Abstract
The excessive secretion of H2O2 within cells is closely associated with cellular dysfunction. Therefore, high sensitivity in situ detection of H2O2 released from living cells was valuable in clinical diagnosis. In the present work, a novel electrochemical cells sensing platform by synthesizing copper nanoclusters (CuNCs) at room temperature based on DNA nanoribbon (DNR) as a template (DNR-CuNCs). The tight and ordered arrangement of nanostructured assemblies of DNR-CuNCs conferred the sensor with superior stability (45 days) and electrochemical performance. The MUC1 aptamer extending from the DNR template enabled the direct capture MCF-7 cells on electrode surface, this facilitated real-time monitoring of H2O2 release from stimulated MCF-7 cells. While the captured MCF-7 cells on the electrode surface significantly amplified the current signal of H2O2 release compared with the traditional electrochemical detection H2O2 released signal by MCF-7 cells in PBS solution. The approach provides an effective strategy for the design of versatile sensors and achieving monitored cell release of H2O2 in long time horizon (10 h). Thereby expanding the possibilities for detecting biomolecules from live cells in clinical diagnosis and biomedical applications.

Abstract
Breast cancer is a leading cause of cancer-related deaths among women. Cisplatin is used for treatment, but the development of resistance in cancer cells is a significant concern. This study aimed to investigate changes in the transcriptomes of cisplatin-resistant MCF7 cells. We conducted RNA sequencing of cisplatin-resistant MCF7 cells, followed by differential expression analysis and bioinformatic investigations to identify changes in gene expression and modified signal transduction pathways. We examined the size and quantity of extracellular vesicles. A total of 724 genes exhibited differential expression, predominantly consisting of protein-coding RNAs. Notably, two long non-coding RNAs (lncRNAs), NEAT1 and MALAT, were found to be dysregulated. Bioinformatic analysis unveiled dysregulation in processes related to DNA synthesis and repair, cell cycle regulation, immune response, and cellular communication. Additionally, modifications were observed in events associated with extracellular vesicles. Conditioned media from resistant cells conferred resistance to wild-type cells in vitro. Furthermore, there was an increase in the number of vesicles in cisplatin-resistant cells. Cisplatin-resistant MCF7 cells displayed differential RNA expression, including the dysregulation of NEAT1 and MALAT long non-coding RNAs. Key processes related to DNA and extracellular vesicles were found to be altered. The increased number of extracellular vesicles in resistant cells may contribute to acquired resistance in wild-type cells.

Abstract
BACKGROUND/AIM Methyl jasmonate (MeJa) is a botanical stress hormone that serves as a defense mechanism to inhibit growth in stressed plants. It is well known that MeJa exhibits an anticancer effect by reducing intracellular ATP, activating reactive oxygen species (ROS) production, and promoting mitogen-activated protein kinase (MAPK) activity. Presently, no report has been published on MeJa-induced changes in intracellular Mg2+ concentration ([Mg2+]i), and TRPM7 as an Mg2+ transporter in cancer cells. Therefore, this study aimed to investigate the Mg2+ homeostatic changes and apoptotic effects following MeJa treatment using the MCF-7 human breast cancer cell line. MATERIALS AND METHODS The MTT assay was used to assess the cell viability and half-inhibitory concentration, microscopic two-photon excitation wavelength spectrophotometry was used to measure the [Mg2+]i, a luminescent assay determined intracellular ATP levels, western blot assay measured TRPM7 levels, antioxidant capacities, endoplasmic reticulum (ER) stress, and MAPK signaling pathways, while the fluorescence assay evaluated ROS concentrations and the cell apoptotic index. RESULTS This study provides evidence that MeJa has an antiapoptotic effect on MCF-7 cells. The increase in [Mg2+]i led to decreased TRPM7 expression, which is related to elevated ROS production, in addition to elevated ER stress and MAPK signaling pathway activity and decreased ATP content. CONCLUSION The increase in [Mg2+]i leads to decreased TRPM7 expression and may be the epicenter of MeJa-induced apoptotic cell death in MCF-7 cells.

Abstract
BACKGROUND There is increasing evidence that honey has anti-inflammatory, antioxidant, and anti-cancer effects. This study aims to assess and contrast the cytotoxic, anti-metastatic, and apoptotic effects of Ziziphus jujube honey and commercial honey on MCF7 cells. METHODS AND RESULTS Two honey samples, Ziziphus jujube (JH) and commercial honey (CH), were categorized into high and low groups based on their phenolic content, antioxidant capacity, and diastase activity (PAD score). The viability and migration ability of MCF-7 cells treated with JH and CH were evaluated. Also, quantitative polymerase chain reaction (Q-PCR) was performed to assess the effect of the two honey samples on the expression of Bax, p53, p21 and Bcl-2 genes. JH had a total phenolic content of 606.4 ± 0.1 µg gallic acid equivalent/mg, while CH had a value of 112.1 ± 0.09 µg gallic acid equivalent/mg. The total antioxidant capacity of the two samples was compared. It was 203.5 ± 10.5µM/l in JH and 4.6 ± 10.5 µM/l in CH. In addition, JH had a diastatic activity of 524.1 ± 0.25 U/l, while CH had a value of 209.7 ± 0.56 U/l. According to the results, JH had a high PAD value, while CH had a low PAD value. Cell viability was measured using the results of the MTT assay. The results showed that JH inhibited the growth of MCF-7 cells more strongly (IC50 of 170 ± 4.2 µg/ml) than CH (IC50 of 385.3 ± 4.5 µg/l). The scratch assay showed that treatment with JH decreased the migration rate of MCF-7 cells in a dose-dependent manner compared to the CH and control groups. In addition, the results of q-PCR analysis showed significant upregulation of Bax, p53 and p21 genes and downregulation of Bcl-2 gene in the JH-treated group compared to the CH and control groups. CONCLUSION These results showed that honey with an increased content of phenolic compounds, antioxidant capacity, and diastatic activity has anticancer properties by effectively suppressing tumor development. This suppression occurs via several mechanisms, including suppression of proliferation and metastasis, and promotion of apoptosis.

Abstract
BACKGROUND Our previous study investigated the levels of soluble growth factors in the conditioned media of bone marrow-derived mesenchymal stem cells (BMSCs) pre-treated with thiazolidinedione solutions. The present study aimed to investigate the complex intracellular proteins extracted from BMSCs pre-treated with pioglitazone and/or rosiglitazone using proteomics. METHODS The proliferative effect of the identified protein on MCF-7 cells that interacted non-adhesively with BMSCs pre-treated with pioglitazone and/or rosiglitazone was evaluated using cell culture inserts and conditioned media. The mRNA expression of proliferation and lipid accumulation markers was also evaluated in the interacted MCF-7 cells by reverse transcription-quantitative PCR. Finally, the correlation between the identified protein and fibroblast growth factor 4 (FGF-4) protein in the conditioned media of the pre-treated BMSCs was evaluated by ELISA. RESULTS The present study identified vimentin as the specific protein among the complex intracellular proteins that likely plays a role in MCF-7 cell proliferation when the breast cancer cells interacted non-adhesively with BMSCs pre-treated with a combination of pioglitazone and rosiglitazone. The inhibition of this protein promoted the proliferation of MCF-7 cells when the breast cancer cells interacted with pre-treated BMSCs. Gene expression analysis indicated that pre-treatment of BMSCs with a combination of pioglitazone and rosiglitazone decreased the mRNA expression of Ki67 and proliferating cell nuclear antigen in MCF-7 cells. The pre-treatment did not induce mRNA expression of PPARγ, which is a sign of lipid accumulation. The level of vimentin protein was also associated with the FGF-4 protein expression level in the conditioned media of the pre-treated BMSCs. Bioinformatics analysis revealed that vimentin regulated the expression of FGF-4 through its interaction with SRY-box 2 and POU class 5 homeobox 1. CONCLUSIONS The present study identified a novel intracellular protein that may represent the promising target in pre-treated BMSCs to decrease the proliferation of breast cancer MCF-7 cells for human health and wellness.

Abstract
Cannabis sativa is a well-known plant for its psychoactive effects; however, its many derivatives, such as Cannabidiol (CBD), contain several therapeutic applications. Tetrahydrocannabinol (THC) is the main cannabis derivative responsible for psychoactive properties, while CBD is non-psychotropic. For this reason, CBD has been more exploited in the last decade. CBD has been connected to multiple anticancer properties, and when combined with photodynamic therapy (PDT), it is possible to eradicate tumors more effectively. In this study, CBD was utilized to treat MCF-7 breast cancer cells, followed by in vitro PDT combination therapy. Conventional breast cancer treatment modalities such as chemotherapy, radiotherapy, etc. have been reported for inducing a number of undesirable side effects, recurrence of the disease, and low quality of life. In this study, cells were exposed to varying concentrations of CBD (i.e., 1.25, 2.5, 5, 10, and 20 μg/mL) and incubated 12 and 24 h after treatment. The optimal doses were then used in combination therapy. Morphology and biochemical assays, including lactate dehydrogenase (LDH) for membrane integrity, adenosine triphosphate (ATP) for viability, and trypan blue exclusion assay for viability, were used to examine cellular responses after treatments. The optimal concentration was then utilized in Hypericin-Gold nanoparticles mediated PDT combination. The results revealed that, in a dose-dependent manner, conventional morphological characteristics of cell death, such as vacuolization, blebbing, and floating were observed in treated cells. The biochemical responses demonstrated an increase in LDH, a decrease in ATP, and a reduction in viability. This study demonstrated that CBD induces cell death in MCF-7 breast cancer cells cultured in vitro. The immunofluorescence results of combination therapy indicated that cell death occurred via apoptosis. In conclusion, this study proposes that the CBD and PDT combination therapy is effective in killing MCF-7 breast cancer cells in vitro by induction of apoptosis.

Abstract
Background Multi-drug resistance is an important challenge in the chemotherapy of cancer. The role of annexin A5 (ANXA5) in the biology of cancer has been the focus of many studies. Breast Cancer (BC) is frequent cancer in women with high morbidity and mortality rate. The present study aimed to investigate the effects of ANXA5 overexpression on the anti-tumor activity of Epirubicin (EPI) in MCF-7 and MCF-7/ADR cells. Methods MCF-7 and MCF-7/ADR cells were transfected with the pAdenoVator-CMV-ANXA5-IRES-GFP plasmid or mock plasmid. The overexpression of ANXA5 was evaluated using qPCR. The effects of ANXA5 overexpression and EPI on the cell viability of MCF-7 and MCF-7/ADR cells were measured using an MTT assay. Cell apoptosis was measured by annexin V/7-AAD flow cytometry assay. Results Following the overexpression of ANXA5, the viability of MCF-7 and MCF-7/ADR was significantly decreased. Furthermore, the overexpression of ANXA5 in MCF-7 cells increased the cytotoxic effects of EPI in all doses and reduced the IC50 of EPI from 17.69 μM to 4.07 μM. Similarly, the overexpression of ANXA5 in MCF7-ADR cells reduced the IC50 of EPI from 27.3 μM to 6.69 μM. ANXA5 overexpression alone or combined with EPI treatment increased the apoptosis of MCF7 and MCF7-ADR cells. Conclusion The results of the present study demonstrate that ANXA5 overexpression increases the sensitivity of MCF-7 and MCF-7/ADR to EPI, suggesting a possible beneficial role of ANXA5 in the therapy of BC.

Abstract
Urinary tract infection is an infectious disease that requires immediate treatment. It can occur in any age group and involves both genders equally. The present study was to check the resistance of some antibiotics and to assess the antibacterial potential of three extracts of three plants against notorious bacteria involved in urinary tract infections. Along with assessing the antibacterial activity of plant extracts, we checked for the anticancer potential of these extracts against the cancer cell lines MCF-7 and A2780. Cancer is the leading cause of mortality in developed countries. Determinations of total flavonoid content, total phenolic content, total alkaloid content, total tannin content, total carotenoid content, and total steroid content were performed. The disk diffusion method was used to analyze the antibacterial activity of plant extracts. Ethanolic extract of Selenicereus undatus showed sensitivity (25-28 mm) against bacteria, whereas chloroform and hexane extracts showed resistance against all bacteria except Staphylococcus (25 mm). Ethanolic extract of Pistacia vera L. showed sensitivity (22-25 mm) against bacteria, whereas chloroform and hexane extracts showed resistance. Ethanolic extract of Olea europaea L. showed sensitivity (8-16 mm) against all bacteria except Staphylococcus, whereas chloroform and hexane extracts showed resistance. Positive controls showed variable zones of inhibition (2-60 mm), and negative control showed 0-1 mm. The antibiotic resistance was much more prominent in the case of hexane and chloroform extracts of all plants, whereas ethanolic extract showed a sensitivity of bacteria against extracts. Both cell lines, MCF-7 and A2780, displayed decreased live cells when treated with plant extracts.

Abstract
Thiadiazole derivatives have garnered significant attention in the field of medicinal chemistry due to their diverse pharmacological activities, including anticancer properties. This article presents the synthesis of a series of thiadiazole derivatives and investigates their chemical characterization and potential anticancer effects on various cell lines. The results of the nuclear magnetic resonance (NMR) analyses confirmed the successful formation of the target compounds. The anticancer potential was evaluated through in silico and in vitro cell-based assays using LoVo and MCF-7 cancer lines. The assays included cell viability, proliferation, apoptosis, and cell cycle analysis to assess the compounds' effects on cancer cell growth and survival. Daphnia magna was used as an invertebrate model for the toxicity evaluation of the compounds. The results revealed promising anticancer activity for several of the synthesized derivatives, suggesting their potential as lead compounds for further drug development. The novel compound 2g, 5-[2-(benzenesulfonylmethyl)phenyl]-1,3,4-thiadiazol-2-amine, demonstrated good anti-proliferative effects, exhibiting an IC50 value of 2.44 µM against LoVo and 23.29 µM against MCF-7 after a 48-h incubation and little toxic effects in the Daphnia test.

Abstract
The effects of insulin on the doxorubicin (Dox) sensitivity of breast cancer cell line MCF-7 and its Dox-resistant counterpart MCF-7/Dox were studied and glucose metabolism, content of essential minerals, and the expression of several microRNAs in these cells upon exposure to insulin and Dox were compared. Cell viability colorimetric assay, colorimetric enzymatic technique, flow cytometry, immunocytochemical techniques, inductively-coupled plasma atomic emission spectroscopy, and quantitative polymerase chain reaction were used in the study. We found that insulin in high concentration significantly suppressed Dox toxicity, especially in parental MCF-7 cell line. The increase in proliferative activity triggered by insulin in MCF-7 but not MCF-7/Dox cells occurred in the setting of the increased level of specific binding sites for insulin and increased glucose uptake. Insulin treatment of MCF-7 cells in low and high concentrations resulted in the increase of Mg, Ca, and Zn content while in DOX-resistant cells, only Mg content increased upon exposure to insulin. High concentration of insulin increased the expression of kinase Akt1, P-glycoprotein 1 (P-gp1) and DNA excision repair protein ERCC-1 in MCF-7 cells, while in MCF-7/Dox cells, Akt1 expression decreased, and cytoplasmic expression of P-gp1 increased. In addition, insulin treatment affected expression of miR-122-5p, miR-133a-3p, miR-200b-3p, and miR-320a-3p. The decreased manifestation of biological effects of insulin in Dox-resistant cells could be partly explained by the different patterns of energy metabolism in MCF-7 cells and their Dox-resistant counterpart.

Abstract
Breast cancer has replaced lung cancer to be the leading cancer in the world. Currently, chemotherapy is still the major method for breast cancer therapy, but its overall effect remains unsatisfactory. Fusaric acid (FSA), a mycotoxin derived from fusarium species, has shown potency against the proliferation of several types of cancer cells, but its effect on breast cancer cells has not been examined. Therefore, we explored the possible effect of FSA on the proliferation of MCF-7 human breast cancer cells and uncovered the underlying mechanism in the present study. Our results showed that FSA has a strong anti-proliferative effect on MCF-7 cells through inducing ROS production, apoptosis and arresting cell cycle at G2/M transition phase. Additionally, FSA triggers endoplasmic reticulum (ER) stress in the cells. Notably, the cell cycle arrest and apoptosis inducing effect of FSA can be attenuated by ER stress inhibitor, tauroursodeoxycholic acid. Our study provide evidence that FSA is a potent proliferation inhibition and apoptosis inducing agent against human breast cancer cells, and the possible mechanism involves the activation of ER stress signaling pathways. Our study may highlight that FSA is promising for the future in vivo study and development of potential agent for breast cancer therapy.

Abstract
Breast cancer has the characteristics of high metastasis and recurrence and ranks first in incidence and mortality among female malignant tumors. Shc SH2-domain binding protein 1 (SHCBP1) is an important protein in intracellular signal transduction and cell division, but the role of SHCBP1 in breast cancers remains elusive. Here, we found that SHCBP1 deficiency inhibited the proliferation of breast cancer cells. Mechanistically, SHCPB1 significantly downregulates the mRNA level of CXCL2, which in turn activates the AKT and ERK signaling, while inactivates the p21 and p27 signaling. In addition, overexpression of SHCPB1 downregulates the protein levels of p21 and p27, which could be completely reversed by restoration of CXCL2 expression. Moreover, we analyzed the expression of both SHCPB1 and CXCL2, and found that SHCPB1 is highly expressed in breast cancer cells or tissues from breast cancer patients compared to normal breast cells or adjacent normal tissues, while CXCL2 is lowly expressed in breast cancer cells or tissues. Collectively, our study reveals that SHCBP1 plays an oncogenic role in breast cancer tumorigenesis partially through inhibiting the inflammatory response and ultimately activating the proliferation of breast cancers.

Abstract
The incidence of aggressive and resistant breast cancers is growing at alarming rates, indicating a necessity to develop better treatment strategies. Recent epidemiological and preclinical studies detected low serum levels of vitamin D in cancer patients, suggesting that vitamin D may be effective in mitigating the cancer burden. However, the molecular mechanisms of vitamin D3 (cholecalciferol, vit-D3)-induced cancer cell death are not fully elucidated. The vit-D3 efficacy of cell death activation was assessed using breast carcinoma cell lines in vitro and a widely used Ehrlich ascites carcinoma (EAC) breast cancer model in vivo in Swiss albino mice. Both estrogen receptor-positive (ER+, MCF-7) and -negative (ER-, MDA-MB-231, and MDA-MB-468) cell lines absorbed about 50% of vit-D3 in vitro over 48 h of incubation. The absorbed vit-D3 retarded the breast cancer cell proliferation in a dose-dependent manner with IC50 values ranging from 0.10 to 0.35 mM. Prolonged treatment (up to 72 h) did not enhance vit-D3 anti-proliferative efficacy. Vit-D3-induced cell growth arrest was mediated by the upregulation of p53 and the downregulation of cyclin-D1 and Bcl2 expression levels. Vit-D3 retarded cell migration and inhibited blood vessel growth in vitro as well as in a chorioallantoic membrane (CAM) assay. The intraperitoneal administration of vit-D3 inhibited solid tumor growth and reduced body weight gain, as assessed in mice using a liquid tumor model. In summary, vit-D3 cytotoxic effects in breast cancer cell lines in vitro and an EAC model in vivo were associated with growth inhibition, the induction of apoptosis, cell cycle arrest, and the impediment of angiogenic processes. The generated data warrant further studies on vit-D3 anti-cancer therapeutic applications.

Abstract
Receptor-mediated drug delivery systems are a promising tool for targeting malignant cells to suppress/inhibit the malignancy without disturbing healthy cells. Protein-based nanocarrier systems possess numerous advantages for the delivery of variety of chemotherapeutics, including therapeutic peptides and genes. In the present work, glucose-conjugated camptothecin-loaded glutenin nanoparticles (Glu-CPT-glutenin NPs) were fabricated to deliver camptothecin to MCF-7 cells via GLUT-1 transporter protein. Initially, Glu-conjugated glutenin polymer was successfully synthesized through reductive amination reaction, and this was confirmed by FTIR and 13C-NMR. Then, camptothecin (CPT) was loaded into Glu-conjugated glutenin polymer forming Glu-CPT-glutenin NPs. The nanoparticles were studied for their drug releasing capacity, morphological shape, size, physical nature, and zeta potential. The fabricated Glu-CPT-glutenin NPs were found to be spherical in shape and amorphous in nature with 200-nm size range and a zeta potential of - 30 mV. Furthermore, MTT assay using Glu-CPT-glutenin NPs confirmed concentration-dependent cytotoxicity against MCF-7 cells after 24-h treatment, and IC50 was found to be 18.23 μg mL-1. In vitro cellular uptake study demonstrated that the Glu-CPT-glutenin NPs had enhanced endocytosis and delivered CPT in MCF-7 cells. A typical apoptotic morphological change of condensed nuclei and distorted membrane bodies was found after treatment with IC50 concentration of NPs. The released CPT from NPs also targeted mitochondria of MCF-7 cells, significantly increasing the level of reactive oxygen species and causing the damage of mitochondrial membrane integrity. These outcomes confirmed that the wheat glutenin can positively serve as a significant delivery vehicle and enhance the anticancer potential of this drug.

Abstract
According to studies, the microbiome may contribute to the emergence and spread of breast cancer. E. coli is one of the Enterobacteriaceae family recently found to be present as part of the breast tissue microbiota. In this study, we focused on the effect of E. coli secretome free of cells on MCF-7 metabolism. Liquid chromatography-mass spectrometry (LC-MS) metabolomics was used to study the E. coli secretome and its role in MCF-7 intra- and extracellular metabolites. A comparison was made between secretome-exposed cells and unexposed controls. Our analysis revealed significant alterations in 31 intracellular and 55 extracellular metabolites following secretome exposure. Several metabolic pathways, including lactate, aminoacyl-tRNA biosynthesis, purine metabolism, and energy metabolism, were found to be dysregulated upon E. coli secretome exposure. E. coli can alter the breast cancer cells' metabolism through its secretome which disrupts key metabolic pathways of MCF-7 cells. These microbial metabolites from the secretome hold promise as biomarkers of drug resistance or innovative approaches for cancer treatment, either as standalone therapies or in combination with other medicines.

Abstract
Oxidative stress and chronic inflammation interplay with the pathogenesis of cancer. Breast cancer in women is the burning issue of this century, despite chemotherapy and magnetic therapy. The management of secondary complications triggered by post-chemotherapy poses a great challenge. Thus, identifying target-specific drugs with anticancer potential without secondary complications is a challenging task for the scientific community. It is possible that green technology has been employed in a greater way in order to fabricate nanoparticles by amalgamating plants with medicinal potential with metal oxide nanoparticles that impart high therapeutic properties with the least toxicity. Thus, the present study describes the synthesis of Titanium dioxide nanoparticles (TiO2 NPs) using aqueous Terenna asiatica fruit extract, with its antioxidant, anti-inflammatory and anticancer properties. The characterisation of TiO2 NPs was carried out using a powdered X-ray diffractometer (XRD), Fourier transform infrared (FTIR), scanning electron microscopy (SEM), energy-dispersive X-ray diffraction (EDX), high-resolution transmission electron microscopy (HR-TEM), dynamic light scattering (DLS), and zeta-potential. TiO2 NPs showed their antioxidant property by scavenging 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radicals in a dose-dependent manner with an IC50 value of 80.21 µg/µL. To ascertain the observed antioxidant potential of TiO2 NPs, red blood cells (RBC) were used as an in vitro model system. Interestingly, TiO2 NPs significantly ameliorated all the stress parameters, such as lipid peroxidation (LPO), protein carbonyl content (PCC), total thiol (TT), superoxide dismutase (SOD), and catalase (CAT) in sodium nitrite (NaNO2)-induced oxidative stress, in RBC. Furthermore, TiO2 NPs inhibited RBC membrane lysis and the denaturation of both egg and bovine serum albumin, significantly in a dose-dependent manner, suggesting its anti-inflammatory property. Interestingly, TiO2 NPs were found to kill the MCF-7 cells as a significant decrease in cell viability of the MCF-7 cell lines was observed. The percentage of growth inhibition of the MCF-7 cells was compared to that of untreated cells at various doses (12.5, 25, 50, 100, and 200 µg/mL). The IC50 value of TiO2 NPs was found to be (120 µg/mL). Furthermore, the Annexin V/PI staining test was carried out to confirm apoptosis. The assay indicated apoptosis in cancer cells after 24 h of exposure to TiO2 NPs (120 µg/mL). The untreated cells showed no significant apoptosis in comparison with the standard drug doxorubicin. In conclusion, TiO2 NPs potentially ameliorate NaNO2-induced oxidative stress in RBC, inflammation and MCF-7 cells proliferation.

Abstract
The dimeric peptide 26[F]: (RRWQWRFKKLG)2-K-Ahx has exhibited a potent cytotoxic effect against breast cancer cell lines, with position 26 (F) being the most relevant for anti-cancer activity. In this investigation, six analogues of the 26[F] peptide were synthesized in which the 26th position was replaced by non-natural hydrophobic amino acids, finding that some modifications increased the resistance to proteolytic degradation exerted by trypsin or pepsin. Additionally, these modifications increased the cytotoxic effect against breast cancer cells and generated cell death mediated by apoptosis pathways, activating caspases 8 and 9, and did not compromise the integrity of the cytoplasmic membrane. Finally, it was found that the modified peptides have a broad spectrum of action, since they also have a cytotoxic effect against the HeLa human cervical cancer cell line. Peptide 26[F] was inoculated in mice by ip administration and the lethal dose 50 (LD50) was between 70 and 140 mg kg-1. While for the 26[1-Nal]: (RRWQWR-1-Nal-KKLG)2-K-Ahx peptide, a dose-response test was performed, and the survival rate was 100%. These results suggested that these peptides are safe in this animal model and could be considered as promissory to develop a treatment against breast cancer.

Abstract
Mitochondrial oxidative phosphorylation (OXPHOS) system dysfunction in cancer cells has been exploited as a target for anti-cancer therapeutic intervention. The downregulation of CR6-interacting factor 1 (CRIF1), an essential mito-ribosomal factor, can impair mitochondrial function in various cell types. In this study, we investigated whether CRIF1 deficiency induced by siRNA and siRNA nanoparticles could suppress MCF-7 breast cancer growth and tumor development, respectively. Our results showed that CRIF1 silencing decreased the assembly of mitochondrial OXPHOS complexes I and II, which induced mitochondrial dysfunction, mitochondrial reactive oxygen species (ROS) production, mitochondrial membrane potential depolarization, and excessive mitochondrial fission. CRIF1 inhibition reduced p53-induced glycolysis and apoptosis regulator (TIGAR) expression, as well as NADPH synthesis, leading to additional increases in ROS production. The downregulation of CRIF1 suppressed cell proliferation and inhibited cell migration through the induction of G0/G1 phase cell cycle arrest in MCF-7 breast cancer cells. Similarly, the intratumoral injection of CRIF1 siRNA-encapsulated PLGA nanoparticles inhibited tumor growth, downregulated the assembly of mitochondrial OXPHOS complexes I and II, and induced the expression of cell cycle protein markers (p53, p21, and p16) in MCF-7 xenograft mice. Thus, the inhibition of mitochondrial OXPHOS protein synthesis through CRIF1 deletion destroyed mitochondrial function, leading to elevated ROS levels and inducing antitumor effects in MCF-7 cells.

Abstract
With great interest, we read the paper "Chitosan nano-vehicles as biocompatible delivering tools for a new Ag(I)curcuminoid-Gboxin analog complex in cancer and inflammation therapy" published in the International Journal of Biological Macromolecules. In Elbehairi's report, the human breast carcinoma line MCF-7 were used in the in vitro cytotoxic analysis test of the curcuminoid conjugate and its silver(I) complex. They found that Ag(I)FLLL49-GbA could induce highly significant up-regulation of caspase-3, tumor suppressor proteins P53, and Bax after the 48 h of treatment in MCF-7 cells (Fig. 9), and the expression of caspase-3 was analyzed by western blot assay. However, it's well known that the MCF-7 breast carcinoma line do not express caspase-3. The lack of caspase-3 in MCF-7 cells is caused by a 47-base pair deletion within exon 3 of the CASP-3 gene resulting in the skipping of this exon during pre-mRNA splicing and introduction of a premature stop codon at position 42 that completely abrogates translation of the CASP-3 mRNA. Therefore, the detection of a caspase-3 protein in caspase-3 deficient MCF-7 cells in this study made us confused. We appreciate the authors' efforts in investigating the effects of chitosan nano-vehicles as biocompatible delivering tools for a new Ag(I)curcuminoid-Gboxin analog complex in cancer and inflammation therapy. Nevertheless, we sincerely suggest that appropriate modification may further solidify the findings of the study.

Abstract
It was previously identified that there may be an active metabolite of bisphenol A (BPA), 4-methyl-2,4-bis(4-hydroxyphenyl)pent-1-ene (MBP). An in vitro system was developed to detect MBP toxicity to the Michigan Cancer Foundation-7 (MCF-7) cells that had been repeatedly exposed to a low dose of the metabolite. MBP profoundly activated estrogen receptor (ER)-dependent transcription as a ligand, with an EC50 of 2.8 nM. Women are continuously exposed to numerous estrogenic environmental chemicals; but their susceptibility to these chemicals may be significantly altered after menopause. Long-term estrogen-deprived (LTED) cells, which display ligand-independent ER activation, are a postmenopausal breast cancer model derived from MCF-7 cells. In this study, we investigated the estrogenic effects of MBP on LTED cells in a repeated exposure in vitro model. The results suggest that i) nanomolar levels of MBP reciprocally disrupt the balanced expression of ERα and ERβ proteins, leading to the dominant expression of ERβ, ii) MBP stimulates ERs-mediated transcription without acting as an ERβ ligand, and iii) MBP utilizes mitogen-activated protein kinase and phosphatidylinositol-3 kinase signaling to evoke its estrogenic action. Moreover, the repeated exposure strategy was effective for detecting low-dose estrogenic-like effects caused by MBP in LTED cells.

Abstract
Background: We hypothesized that the antitumor effects of asiaticoside on breast cancer are driven by its ability to decrease the expression of tumor inflammation-promoting genes and increase apoptotic signaling. In this study, we aimed to better understand the mechanisms of action of asiaticoside as a chemical modulator or as a chemopreventive agent in breast cancer. Methods: MCF-7 cells were cultured and treated with 0, 20, 40, and 80 μM asiaticoside for 48 h. Fluorometric caspase-9, apoptosis, and gene expression analyses were conducted. For the xenograft experiments, we divided nude mice into the following 5 groups (10 animals per group): group I, control mice; group II, untreated tumor-bearing nude mice; group III, tumor-bearing nude mice treated with asiaticoside at weeks 1-2 and 4-7 and injected with MCF-7 cells at week 3; group IV, tumor-bearing nude mice injected with MCF-7 cells at week 3 and treated with asiaticoside beginning at week 6; and group V, nude mice treated with asiaticoside, as a drug control. After treatment, weight measurements were performed weekly. Tumor growth was determined and analyzed using histology and DNA and RNA isolation. Results: In MCF-7 cells, we found that asiaticoside increased caspase-9 activity. In the xenograft experiment, we found that TNF-α and IL-6 expression decreased (p < 0.001) via the NF-κB pathway. Conclusion: Overall, our data suggest that asiaticoside produces promising effects on tumor growth, progression, and tumor-associated inflammation in MCF-7 cells as well as a nude mouse MCF-7 tumor xenograft model.

Abstract
Fe3O4/Au/porous Au nanohybrids being bi-functional nanoparticles with magnetic properties and high porosity, were synthesized and used for drug delivery. To achieve this purpose, after Fe3O4 nanoparticles synthesis, a gold layer coats them to increase their stability. Then, to improve the loading capacity of Fe3O4/Au nanoparticles, a shell of porous gold was synthesized on the Fe3O4/Au surface by creating an Ag-Au nanohybrid layer on Fe3O4/Au and dissolving the metallic silver atoms in HNO3 (0.01 M). The DLS results show that the synthesized nanohybrid has an average size of 68.0 ± 7.7 nm and a zeta potential of - 28.1 ± 0.2 mV. Finally, doxorubicin (DOX), as a pharmaceutical agent, was loaded onto the Fe3O4/Au/porous Au nanohybrids. The prepared nano-drug enhanced the therapeutic efficacy of DOX on MCF-7 cancer cells compared to the free DOX. These results confirmed a 1.5 times improvement in the antitumor activity of DOX-loaded Fe3O4/Au/porous Au nanohybrids.

Abstract
MicroRNA 193a-3p (miR193a-3p) is a short non-coding RNA with tumor suppressor properties. Breast cancer (BC) progression is governed by active interaction between breast cancer cells, vascular (V)/lymphatic (L) endothelial cells (ECs), and BC secretome. We have recently shown that miR193a-3p, a tumor suppressor miRNA, inhibits MCF-7 BC cell-driven growth of VECs via direct antimitogenic actions and alters MCF-7 secretome. Since LEC-BC cross-talk plays a key role in BC progression, we investigated the effects of miR193a-3p on MCF-7 secretome and estradiol-mediated growth effects in LECs and LEC + MCF-7 spheroids, and delineated the underlying mechanisms. Transfection of LECs with miR193a-3p, as well as secretome from MCF-7 transfected cells, inhibited LEC growth, and these effects were mimicked in LEC + MCF-7 spheroids. Moreover, miR193a-3p inhibited ERK1/2 and Akt phosphorylation in LECs and LEC + MCF-7 spheroids, which are importantly involved in promoting cancer development and metastasis. Treatment of LECs and LEC + MCF-7 spheroids with estradiol (E2)-induced growth, as well as ERK1/2 and Akt phosphorylation, and was abrogated by miR193a-3p and secretome from MCF-7 transfected cells. Gene expression analysis (GEA) in LEC + MCF-7 spheroids transfected with miR193a-3p showed significant upregulation of 54 genes and downregulation of 73 genes. Pathway enrichment analysis of regulated genes showed significant modulation of several pathways, including interferon, interleukin/cytokine-mediated signaling, innate immune system, ERK1/2 cascade, apoptosis, and estrogen receptor signaling. Transcriptomic analysis showed downregulation in interferon and anti-apoptotic and pro-growth molecules, such as IFI6, IFIT1, OSA1/2, IFITM1, HLA-A/B, PSMB8/9, and PARP9, which are known to regulate BC progression. The cytokine proteome array of miR193a-3p transfected MCF secretome and confirmed the upregulation of several growth inhibitory cytokines, including IFNγ, Il-1a, IL-1ra, IL-32, IL-33, IL-24, IL-27, cystatin, C-reactive protein, Fas ligand, MIG, and sTIM3. Moreover, miR193a-3p alters factors in MCF-7 secretome, which represses ERK1/2 and Akt phosphorylation, induces pro-apoptotic protein and apoptosis in LECs, and downregulates interferon-associated proteins known to promote cancer growth and metastasis. In conclusion, miR193a-3p can potentially modify the tumor microenvironment by altering pro-growth BC secretome and inhibiting LEC growth, and may represent a therapeutic molecule to target breast tumors/cancer.

Abstract
Cancer is one of the most common diseases nowadays and derives from the uncontrollable growth of a single cell. Magnetic nanoparticles (NpMag) offer various possibilities for use in the biomedical area, including drug delivery mediated by magnetic fields. In the current study, we evaluated the in vitro effects of iron-oxide magnetic nanoparticles conjugated with the antitumor drug doxorubicin (Dox) on human breast cancer cells. Our results revealed that magnetic nanoparticles with Dox (NpMag+Dox) induce cellular redox imbalance in MCF-7 cells. We also demonstrate that iron-oxide nanoparticles functionalized with Dox induce oxidative stress evidenced by DNA damage, lipid peroxidation, cell membrane disruption, and loss of mitochondria potential. As a result, NpMag+Dox drives MCF-7 cells to stop the cell cycle and decrease cell migration. The association of NpMg+Dox induced a better delivery of Dox to MCF cells, mainly in the presence of a magnetic field, increasing the death of MCF cells which might reduce the toxicity for healthy cells providing a better efficacy for the treatment. Thus, iron-oxide nanoparticles and doxorubicin conjugated may be candidate for anticancer therapy.

Abstract
Objectives Nanotechnology has helped a lot in diagnosing and treating multiple illnesses, specifically cancer, and increasing the development of targeted drug delivery methods. Nanocomposites are materials with at least one component smaller than 100 nm. Therefore, this study aims to assess the anticancer effects of silver-graphene nanocomposite on MCF-7. Materials and Methods In this study, the rate of inhibition of cancer cell growth and production of reactive oxygen radicals, malondialdehyde, and glutathione stores in MCF7 cells were investigated. Cancer cells were exposed to nano particles for 48 hr. Silver nanoparticles and graphene both reduced the growth rate of MCF-7. Results Subsequently, by treating the cells with silver-graphene nanocomposite, the rate of inhibition of cell growth at the highest concentration was 84.60%. Nanoparticles also inhibited the growth of cancer cells through the oxidative stress pathway by increasing the amount of intracellular ROS, followed by increasing malondialdehyde and decreasing glutathione stores, so that at the highest combined concentration of nanoparticles, the amounts of LPO and ROS increased up to 70% and 74 %, and glutathione reserves decreased by 16%. Conclusion Treatment of MCF-7 cells with silver or graphene nanoparticles and combination treatment with these two substances against cisplatin have sound effects, and by affecting oxidative stress factors, such as increased ROS and subsequent increase in lipid membrane damage, inhibit cell growth and proliferation. According to the mathematical model, silver graphene nanocomposite> silver nanoparticles> graphene has the best effect in inhibiting the growth of cancer cells, respectively.

Abstract
The focus of this research is to design a bioengineered drug delivery vehicle that is efficient in anti-cancer drug delivery in a controlled manner. The experimental work focuses on constructing a methotrexate-loaded nano lipid polymer system (MTX-NLPHS) that can transport methotrexate (MTX) in MCF-7 cell lines in a controlled manner through endocytosis via phosphatidylcholine. In this experiment, MTX is embedded with polylactic-co-glycolic acid (PLGA) in phosphatidylcholine, which acts as a liposomal framework for regulated drug delivery. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and dynamic light scattering (DLS) were utilized to characterize the developed nanohybrid system. The particle size and encapsulation efficiency of the MTX-NLPHS were found to be 198 ± 8.44 nm and 86.48 ± 0.31 %, respectively, which is suitable for biological applications. The polydispersity index (PDI) and zeta potential of the final system were found to be 0.134 ± 0.048 and -28 ± 3.50 mV, respectively. The lower value of PDI showed the homogenous nature of the particle size, whereas higher negative zeta potential prevented the system from agglomeration. An in vitro release kinetics was conducted to see the release pattern of the system, which took 250 h for 100% drug release This kind of system may carry the drug for a long time in the circulatory system and prevent the drug discharge. Other cell culture assays such as 3-(4, 5-dimethyl thiazolyl-2)-2, 5-diphenyltetrazolium bromide (MTT) and reactive oxygen species (ROS) monitoring were used to see the effect of inducers on the cellular system. MTT assay showed cell toxicity of MTX-NLPHS reduced at the lower concentration of the MTX, however, toxicity increased at the higher concentration of the MTX as compared to free MTX. ROS monitoring c revealed more scavenging of ROS using MTX-NLPHS as compared to free MTX. Confocal microscopy suggested the MTX-NLPHS induced more nuclear elongation with cell shrinkage comparatively.

Abstract
INTRODUCTION Worldwide, breast cancer is the most common cancer in women and is the main cause of death among all neoplasia in this group. Luminal A breast cancer represents approximately 70% of all breast cancers and is treated with hormone therapies targeting estrogen receptor alpha (ERα). Unfortunately, patients develop drug resistance leading to recurrence of neoplasia due to estrogen-independent ERα reactivation. Therefore, it is crucial to identify new molecular targets downstream ERα signaling pathway that allows the implementation of better treatments to improve the outcome of breast cancer patients. Overexpression of c-Fos, an ERα gene target, has been associated with increased cell motility, malignancy, metastasis, and invasion while its neutralization results in decreased breast cancer tumorigenesis. The aryl hydrocarbon receptor (AHR) ligands halogenated and polycyclic aromatic hydrocarbons, highly toxic compounds, down regulate c-Fos and ERα levels. The present study aimed to evaluate whether 6-formylindolo(3,2-b)carbazole (FICZ), a no toxic AHR agonist, modifies c-Fos levels in MCF-7 mammary carcinoma cells as well as to determine its effects on cell proliferation and migration. In addition, the possible mechanism through which FICZ mediates c-Fos levels in MCF-7 cells was investigated. METHODS Initially, the effect of FICZ on c-Fos mRNA and protein levels in MCF-7 cells, untreated or treated with estradiol, was evaluated by qPCR and Western blot. 2,3,7,8-Tetrachloro-dibenzo-p-dioxin, an AHR prototype agonist, was used as a positive control. Next, we examined the effect of FICZ on MCF-7 cell proliferation and migration by cell counting, MTT, 3H-thymidine incorporation, and scratch-wound assays. Finally, the involvement of proteasome 26S on ERα and c-Fos protein degradation was investigated by the use of MG132 and Western blot. RESULTS The data show that FICZ treatment downregulates c-Fos mRNA and protein levels, most likely by promoting ERα proteasome degradation, blocking MCF-7 cell proliferation and migration. The results also demonstrate that liganded ERα was required for FICZ-mediated ERα degradation. CONCLUSIONS Activation of AHR results in a decreased MCF-7 cell proliferation and migration by ERα and c-Fos down regulation. Targeting AHR might be a promising therapy for breast cancer treatment, particularly when estrogen-independent ERα reactivation presents.

Abstract
Objective To investigate the anticancer effect of Illicium verum against human breast cancer MCF-7 cell line. Methods An experimental study was conducted in Multidisciplinary and Tissue Culture Laboratory, Aga Khan University in collaboration with Pharmacology Department of Bahria University Medical and Dental College, Karachi, Pakistan from January 2021 to June 2021. MCF-7 cells of Luminal-A breast cancer were seeded in 96-well plate and treated with I.verum methanol extract. After incubation, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) dye was used for cell viability and cell proliferation assays to determine the number of dead and viable cells, and the absorbance was measured using an enzyme-linked immunosorbent assay (ELISA) plate reader. In cell viability assay, different doses of I. verum methanol extract were used to treat the MCF-7 (0.25, 0.5, 1, 3, 6, 12, 25, and 50μg/ml) cells. For apoptosis analysis, the cells were processed with 4´, 6-diamidino-2-phenylindole fluorescent nuclear dye (DAPI) and were examined for fluorescence intensity and apoptotic cells. For cell proliferation assay and apoptosis the IC50 dose of 5.5μg/ml I. verum methanol extract was used. Results The MCF-7 cells showed a significant reduction (p-value <0.01) in cell viability in the presence of all tested doses of I. verum methanol extract, except for the dose of 0.25μg/ml. The IC50 dose 5.5μg/ml of same extract also showed a significant reduction (p-value <0.01) in cell proliferation and apoptosis induction in MCF-7 cells. Conclusions Illicium verum methanol extract possesses very potent anticancer action against MCF-7 cells through cytotoxicity, reduction, and inhibition of cancer cells and by inducing apoptosis.

Abstract
Mathematical modeling of cancer systems is beginning to be used to design better treatment regimens, especially in chemotherapy and radiotherapy. The effectiveness of mathematical modeling to inform treatment decisions and identify therapy protocols, some of which are highly nonintuitive, is because it enables the exploration of a huge number of therapeutic possibilities. Considering the immense cost of laboratory research and clinical trials, these nonintuitive therapy protocols would likely never be found by experimental approaches. While much of the work to date in this area has involved high-level models, which look simply at overall tumor growth or the interaction of resistant and sensitive cell types, mechanistic models that integrate molecular biology and pharmacology can contribute greatly to the discovery of better cancer treatment regimens. These mechanistic models are better able to account for the effect of drug interactions and the dynamics of therapy. The aim of this chapter is to demonstrate the use of ordinary differential equation-based mechanistic models to describe the dynamic interactions between the molecular signaling of breast cancer cells and two key clinical drugs. In particular, we illustrate the procedure for building a model of the response of MCF-7 cells to standard therapies used in the clinic. Such mathematical models can be used to explore the vast number of potential protocols to suggest better treatment approaches.

Abstract
The purpose of current research was to assess the apoptotic effects of biofabrication silver nanoparticles (AgNPs) mediated by the aqueous extract of Phlomis armeniaca on human breast cancer cells (MCF-7 and MDA-MB-231) in monolayer (2D) and spheroid (3D) cultures. The biosynthesized AgNPs were characterized by UV-Vis spectrophotometer (the peaks of resonances at 432 nm), scanning electron microscopy (SEM) and energy-dispersive X-ray spectrometry (EDS). 1-20 µM/mL AgNPs were applied to MCF-7 and MDA-MB-231 cell lines to determine IC50 values at 24, 48 and 72nd h and were found to be 10 µM/mL for both cell lines. Immunohistochemical staining results of BrdU, TUNEL, caspase-3 and Endo G in both 2D and 3D cultures and gene expression levels of caspases (caspase-3, -8 and -9) and Endo G were evaluated. Moreover, the total oxidant/antioxidant status (TOS-TAS) due to AgNPs application in both cell culture mediums was evaluated. AgNPs treatment results in both cell lines in both 2D and 3D cultures showed a significant decrease in the BrdU labeling index, while large amounts of cells were labelled with TUNEL and Endo G. In 2D culture, Endo G expression increased in MCF-7 cells at 48 and 72nd hours, while it increased significantly in MDA-MB-231 cells at all hours. OSI results show that ROS production is increased in cell medium treated with AgNPs. In conclusion, AgNPs mediated by Phlomis armeniaca, synthesized by a green method, successfully induced damage to mitochondria, resulting in cell cycle arrest and consequent cell proliferation blockade and death in both MCF-7 and MDA-MB-231 cells.

Abstract
Objectives Controlled drug delivery using nanotechnology enhances drug targeting at the site of interest and prevents drug dispersal throughout the body. This study focused on loading a poorly water-soluble drug tamoxifen (TMX) into silica nanoparticles (SNPs) and amine-functionalized mesoporous silica nanoparticles (NH2-SBA-15). Materials and Methods SNPs were prepared according to the Stöber method and functionalized with an amine group using 3-aminopropyl triethoxysilane (APTES) through a one-pot synthesis method to produce amine-functionalized mesoporous silica nanoparticles (NH2-SBA-15). Characterization of both nanoparticles was performed using FT-IR, FE-SEM, CHN analysis, porosity tests (BET), and dynamic light scattering (DLS). Results The results showed an average particle size of 103.7 nm for SNPs and 225.9 nm for NH2-SBA-15. Based on the BET results, the pore size of NH2-SBA-15 was about 5.4 nm. In both silica nanoparticles, drug release at pH=5.7 was greater than that of pH=7.4. However, Tamoxifen-loaded NH2-SBA-15 (TMX@NH2-SBA-15) indicated the highest drug release in the acidic medium among TMX-loaded SNPs (TMX@SNPs), perhaps due to the high columbic repulsion in the functionalized NH2-SBA-15 nanoparticles. Regarding cytotoxicity results against MCF-7 breast cancer cell lines, both TMX@SNPs and TMX@NH2-SBA-15 nanoparticles exhibited greater cytotoxicity compared to the free TMX as a positive control. Although TMX@SNPs had a small size and high loading capacity, the cytotoxic effects were higher than those of TMX@NH2-SBA-15. Conclusion Amine functionalization of SNPs can improve the potential activity of these nanoparticles for target therapy.

Abstract
PURPOSE The effects of extended Δ9-tetrahydrocannabinol (Δ9-THC) exposure on estrogen receptor-positive human breast cancer MCF-7 cells have been investigated; however, the effects of Δ9-THC exposure for a shorter duration remain unclear. In this study, we sought to study whether Δ9-THC stimulates the migration of MCF-7 cells under both estrogenic and estrogen-deprived conditions over a short period (approximately 6 h). METHODS MCF-7 cells were treated with Δ9-THC under estrogenic or estrogen-deprived conditions, and cell migration was subsequently analyzed. RESULTS Δ9-THC-stimulated migration of MCF-7 cells 6 h after exposure was only observed in the estrogen-deprived condition. However, Δ9-THC-mediated migration was counteracted under estrogenic conditions without affecting cell proliferation and estrogen receptor expression during this period. CONCLUSIONS Δ9-THC can stimulate MCF-7 cell migration under estrogen-deprived conditions; however, there is an interfering interaction between Δ9-THC and the estrogenic milieu that influences the migration of MCF-7 cells.

Abstract
Many of the chemotherapeutic drugs for the treatment of cancer are molecules identified and isolated from plants or their synthetic derivatives. This work aimed to identify the bioactive compounds using LC-MS and GC-MS and to evaluate the anticancer activity of the methanolic extracts of roots, stems, leaves, and flowers from Cladanthus mixtus. The anticancer activity was evaluated in vitro against two cancer cell lines: human breast carcinoma (MCF-7) and human prostate carcinoma (PC-3), using the MTT assay and microscopic observation. A human normal lung fibroblast (MRC-5) was included to determine the extract's safety for non-tumoral cells. The chemical composition results by LC-MS analysis revealed the presence of 24 phenolic compounds. Furthermore, GC-MS analysis allowed the identification of many biomolecules belonging to terpenoids, esters, alcohols, alkanes, fatty acids, organic acids, benzenes, phenols, ketones, carbonyls, amines, sterols, and other groups. The findings suggest that the majority of C. mixtus extracts have antiproliferative activity against two cancer cell lines, MCF-7 and PC-3, and one non-tumoral cell line, MRC-5. The activity was dose-dependent, and the highest effect was obtained with leaf extract in the two cancer cell lines. Moreover, these extracts demonstrated an acceptable toxicological profile against normal cells. Overall, C. mixtus extracts revealed promising antitumor properties provided by their phytochemical composition.

Abstract
This study aimed to synthesize the nickel (Ni) doped cobalt ferrite (CFO) nanoparticles and to determine its anticancer effect on breast cancer MCF-7 cells. The various concentrations of Ni (0.2%, 0.4%, 0.6%, 0.8%, and 1%) doped CFO nanoparticles were synthesized using Coriandrum sativum extracts by precipitation technique. The synthesized Ni-CFO was characterized by X-ray diffraction, Fourier transform infrared spectroscopic, transmission electron microscopy, and vibrating sample magnetometer analyses. The results show that 0.8% Ni-CFO nanoparticles showed good magnetic properties and antioxidant activity than other concentrations of Ni-CFO. The results showed that the administration of 0.8% Ni-CFO nanoparticles promoted apoptosis, and reduced cell adhesion and migration of MCF-7 cells, as demonstrated by increased lipid peroxidation, decreased antioxidant levels such as superoxide dismutase, catalase, and glutathione peroxidase, and increased formation of reactive oxygen species. Moreover, administration of 0.8% Ni-CFO nanoparticles decreased the Bcl-2 expression while activating the expression of p53, Bax, and cleaved caspase 3, 8 and 9 protein expression. Notably, 0.8% Ni-CFO treatment reduced phospho-PI3K, phospho-Akt, and phospho-mTOR expression levels. As a result, via altering apoptotic related proteins, 0.8% Ni-CFO induced cell death. Therefore, the 0.8% Ni-CFO could be utilized to treat breast cancer.

Abstract
Breast cancer represents the most frequently occurring cancer globally among women. As per the recent report of the World Health Organization (WHO), it was documented that by the end of the year 2020, approximately 7.8 million females were positively diagnosed with breast cancer and in 2020 alone, 685,000 casualties were documented due to breast cancer. The use of standard chemotherapeutics includes the frontline treatment option for patients; however, the concomitant side effects represent a major obstacle for their usage. Carbazole alkaloids are one such group of naturally-occurring bioactive compounds belonging to the Rutaceae family. Among the various carbazole alkaloids, 3-Methoxy carbazole or C13H11NO (MHC) is obtained from Clausena heptaphylla as well as from Clausena indica. In this study, MHC was investigated for its anti-breast cancer activity based on molecular interactions with specific proteins related to breast cancer, where the MHC had predicted binding affinities for NF-κB with −8.3 kcal/mol. Furthermore, to evaluate the biological activity of MHC, we studied its in vitro cytotoxic effects on MCF-7 cells. This alkaloid showed significant inhibitory effects and induced apoptosis, as evidenced by enhanced caspase activities and the cellular generation of ROS. It was observed that a treatment with MHC inhibited the gene expression of NF-kB in MCF-7 breast cancer cells. These results suggest that MHC could be a promising medical plant for breast cancer treatment. Further studies are needed to understand the molecular mechanisms behind the anticancer action of MHC.

Abstract
Chimeric antigen receptor (CAR) immunotherapy includes the genetic modification of immune cells to carry such a receptor and, thus, recognize cancer cell surface antigens. Viral transfection is currently the preferred method, but it carries the risk of off-target mutagenicity. Other transfection platforms have thus been proposed, such the in vitro transcribed (IVT)-mRNAs. In this study, we exploited our innovative, patented delivery platform to produce protein transduction domain (PTD)-IVT-mRNAs for the expression of CAR on NK-92 cells. CAR T1E-engineered NK-92 cells, harboring the sequence of T1E single-chain fragment variant (scFv) to recognize the ErbB receptor, bearing either CD28 or 4-1BB as co-stimulatory signaling domains, were prepared and assessed for their effectiveness in two different ErbB(+) cancer cell lines. Our results showed that the PTD-IVT-mRNA of CAR was safely transduced and expressed into NK-92 cells. CAR T1E-engineered NK-92 cells provoked high levels of cell death (25-33%) as effector cells against both HSC-3 (oral squamous carcinoma) and MCF-7 (breast metastatic adenocarcinoma) human cells in the co-incubation assays. In conclusion, the application of our novel PTD-IVT-mRNA delivery platform to NK-92 cells gave promising results towards future CAR immunotherapy approaches.

Abstract
Introduction Introduction: Chemotherapy, biotherapy, and radiotherapy play a limited but important role in treating breast cancer. For more efficient treatment, combination therapy could be an appropriate option. In this study, radiotherapy using neutron radiation emitted from a 241Am-Be neutron source, as well as biotherapy using curcumin (80 μM) was combined to investigate the efficiency of treatment towards MCF-7 breast cancer in a three dimensional (3D) culture medium. Methods Methods: MTT, neutral red uptake assay, nitric oxide, glutathione assay, catalase, cytochrome c, comet assay, and caspase-3 were used to determine the effect of neutron radiation and also neutron and curcumin combination on the viability of cancer cells. Results Results: The results of cytotoxicity test showed that neutron irradiation with or without curcumin at 5, 10, 15, and 20 h reduced the survival of tumor cells. Moreover, the rate of apoptosis due to the neutron effect at different irradiation times enhanced with the increasing time. Conclusion Conclusion: Due to the significant anticancer effect of curcumin in 3D culture, using this molecule before or after neutron therapy is recommended.

Abstract
This study aimed to evaluate the safety and potential use of soy isoflavones in the treatment of skin problems, difficult-to-heal wounds and postoperative scars in women after the oncological treatment of breast cancer. The effects of different concentrations of genistein as a representative of soy isoflavonoids on MCF-7 tumor cells and BJ skin fibroblasts cultured in vitro were assessed. Genistein affects both healthy dermal BJ fibroblasts and cancerous MCF-7 cells. The effect of the tested isoflavonoid is closely related to its concentration. High concentrations of genistein destroy MCF-7 cancer cells, regardless of the exposure time, with a much greater effect on reducing cancer cell numbers at longer times (48 h). Lower concentrations of genistein (10 and 20 μM) increase the abundance of dermal fibroblasts. However, higher concentrations of genistein (50 μM and higher) are detrimental to fibroblasts at longer exposure times (48 h). Our studies indicate that although genistein shows high potential for use in the treatment of skin problems, wounds and surgical scars in women during and after breast cancer treatment, it is not completely safe. Introducing isoflavonoids to treatment requires further research into their mechanisms of action at the molecular level, taking into account genetic and immunological aspects. It is also necessary to conduct research in in vivo models, which will allow for eliminating adverse side effects of therapy.

Abstract
Fluorescent silica nanoparticles with a polymer shell of poly (D, L-lactide-co-glycolide) (PLGA) can provide traceable cell-triggered delivery of the anticancer drug doxorubicin (DOX), protecting the cargo while in transit and releasing it only intracellularly. PLGA with 50:50 lactide:glycolide ratio was grown by surface-initiated ring-opening polymerization (ROP) from silica nanoparticles of ca. 50 nm diameter, doped with a perylenediimide (PDI) fluorescent dye anchored to the silica structure. After loading DOX, release from the core-shell particles was evaluated in solution at physiological pH (7.4), and in human breast cancer cells (MCF-7) after internalization. The hybrid silica-PLGA nanoparticles can accommodate a large cargo of DOX, and the release in solution (PBS) due to PLGA hydrolysis is negligible for at least 72 h. However, once internalized in MCF-7 cells, the nanoparticles release the DOX cargo by degradation of the PLGA. Accumulation of DOX in the nucleus causes cell apoptosis, with the drug-loaded nanoparticles found to be as potent as free DOX. Our fluorescently traceable hybrid silica-PLGA nanoparticles with cell-triggered cargo release offer excellent prospects for the controlled delivery of anticancer drugs, protecting the cargo while in transit and efficiently releasing the drug once inside the cell.

Abstract
Hypoxia-inducible factor-1α (HIF-1α) is a major transcriptional regulator that plays a crucial role in the hypoxic response of rapidly growing tumors. Overexpression of HIF-1α has been associated with breast cancer metastasis and poor clinical prognosis. Plumbagin, the main phytochemical from Plumbago indica, exerts anticancer effects via multiple mechanisms. However, its precise mechanisms on breast cancer cells under hypoxic conditions has never been investigated. This study aims to examine the anticancer effect of plumbagin on MCF-7 cell viability, transcriptional activity, and protein expression of HIF-1α under normoxia and hypoxia-mimicking conditions, as well as reveal the underlying signaling pathways. The results demonstrate that plumbagin decreased MCF-7 cell viability under normoxic conditions, and a greater extent of reduction was observed upon exposure to hypoxic conditions induced by cobalt chloride (CoCl2). Mechanistically, MCF-7 cells upregulated the expression of HIF-1α protein, mRNA, and the VEGF target gene under CoCl2-induced hypoxia, which were abolished by plumbagin treatment. In addition, inhibition of HIF-1α and its downstream targets did not affect the signaling transduction of the PI3K/Akt/mTOR pathway under hypoxic state. This study provides mechanistic insight into the anticancer activity of plumbagin in breast cancer cells under hypoxic conditions by abolishing HIF-1α at transcription and post-translational modifications.

Abstract
BACKGROUND Astragalus Polysaccharides (APS) had been reported to exhibit antitumor activities. Given that nanoparticles possessed unique advantages in cancer treatment, APS was used as the modifier to prepare gold, silver and selenium nanoparticles (APS-Au, APS-Ag and APS-Se NPs) in the present study. METHODS The three nanoparticles were synthesized via a green approach and characterized by DLS, TEM, XRD, FT-IR and UV-Vis. The inhibitory effects of these nanoparticles on various tumor cells proliferation were examined by MTT assay in vitro. Reactive oxygen species (ROS), mitochondrial membrane potential (MMP) and the expression of apoptosis and autophagy-related proteins were also detected. RESULTS Among these, APS-Se NPs displayed the most potent antitumor activities against MCF-7 cells in vitro. Flow cytometric analysis suggested that after cells were exposed to elevated concentrations of APS-Se NPs (10, 20 and 40 μmol/L), the rate of apoptosis was increasing (16.63 ± 0.89, 38.60 ± 3.46 and 44.38 ± 2.62%, respectively). Further analysis by immunofluorescence revealed an increase in intracellular ROS and a loss of MMP. This was accompanied by increased LC3-I to LC3-II conversion. Also, western blot analysis demonstrated that the ratios of Bax/Bcl-2 and cleaved caspase9/caspase 9 rose, and LC3-II and p62 protein levels increased. The addition of chloroquine, an inhibitor of autophagy, further enhanced protein expression of p62 and LC3-II. CONCLUSION APS-Se NPs exerted their cytotoxic activity in MCF-7 cells by blocking autophagy and facilitating mitochondrial pathway-mediated apoptosis.

Abstract
Cadmium (Cd) could reduce abnormal cell morphology and membrane permeability, however, there are few studies on the detoxification of Cd-reduced cell membrane toxicity. In the present study, we firstly studied the effects of zinc chloride (ZnCl2), n-acetyl-L-cysteine (NAC), and calcium/calmodulin dependent protein kinase II inhibitor (KN93) on cell membrane permeability, respectively; then, we studied the inhibitory effects of ZnCl2, NAC, and KN93 on Cd2+-induced abnormal cell membrane permeability by scanning electrochemical microscopy (SECM) scanning imaging, transverse scanning curve and DPV technology. Our results showed that 10 μmol·L-1 ZnCl2, 0.5 mmol·L-1 NAC and 5 μmol·L-1 KN93 could significantly improve the activity of MCF-7 cells, while did not destroy the cell morphology and membrane permeability. 0.5 mmol·L-1 NAC and 5 μmol·L-1 KN93 could significantly inhibit the effects of Cd2+ on the morphology and membrane permeability of MCF-7 cells (p < 0.01). 10 μmol·L-1 ZnCl2 could significantly inhibit the effect of Cd on the membrane permeability of MCF-7 cells, however, it cannot completely eliminate the morphological changes of MCF-7 cells caused by Cd2+. The results of cell activity experiment showed that 10 μmol·L-1 ZnCl2, 0.5 mmol·L-1 NAC and 5 μmol·L-1 KN93 could inhibit the effect of Cd2+ on the activity of MCF-7 cells. By comparing the inhibitory effects of ZnCl2, NAC and KN93 on Cd2+- induced cytotoxicity, 5 μmol·L-1 KN93 had the robust effect on the maintenance of MCF-7 cell morphology and cell membrane integrity. Our research provided evidence on Zn supplement, NAC as antioxidant drugs, and KN93 as special inhibitor for the detoxification of Cd2+-reduced abnormal cell morphology and membrane permeability.

Abstract
The purpose of this study was to evaluate the potential of a newly modified cyclodextrin derivative, water-soluble β-cyclodextrin–epichlorohydrin (β-CD), as an effective drug carrier to enhance the poor solubility and bioavailability of galangin (GAL), a poorly water-soluble model drug. In this regard, inclusion complexes of GAL/β-CDP were prepared. UV-VIS spectrophotometry, Fourier-transform infrared spectroscopy (FTIR), X-ray crystallography (XRD), zeta potential analysis, particle size analysis, field emission scanning electron microscopy (FESEM), and transmission electron microscopy (TEM) were applied to characterize the synthesized GAL/β-CD. Michigan Cancer Foundation-7 (MCF-7; human breast cancer cells) and rat embryo fibroblast (REF; normal cells) were employed to examine the in vitro cytotoxic effects of GAL/β-CD using various parameters. The dye-based tests of MTT and crystal violet clearly exhibited that GAL/β-CD-treated cells had a reduced proliferation rate, an influence that was not found in the normal cell line. The cells’ death was found to follow apoptotic mechanisms, as revealed by the dye-based test of acridine orange/ethidium bromide (AO/EtBr), with the involvement of the mitochondria via caspase-3-mediated events, as manifested by the Rh 123 test. We also included a mouse model to examine possible in vivo toxic effects of GAL/β-CD. It appears that the inclusion complex does not have a significant influence on normal cells, as indicated by serum levels of kidney and liver enzymatic markers, as well as thymic and splenic mass indices. A similar conclusion was reached on the histological level, as manifested by the absence of pathological alterations in the liver, kidney, thymus, spleen, heart, and lung.

Abstract
The utilization of novel compounds as cancer treatments offers enormous potential in this field. The advantages of nanomedicine-based therapy include efficient cellular uptake and selective cell targeting. In this study, we employ selenium nanoparticles' green-synthesized by apigenin (SeNPs-apigenin) to treat breast cancer. We used various assays to show that SeNPs-apigenin can reduce MCF-7 cell viability and trigger apoptosis in vitro. Flow cytometry and PCR methods were used to detect apoptosis, while cell migration and invasion methods were used to quantify the possible effect of SeNPs-apigenin therapy on cell migration and invasion. According to cytotoxicity testing, the SeNPs-apigenin treatment can successfully limit MCF-7 cell proliferation and viability in a concentration-dependent manner. Flow cytometric and PCR analyses revealed that SeNPs-apigenin treatment induced apoptosis in MCF-7 cells, demonstrating that SeNPs-apigenin treatment could directly target Bcl-2, Bax, and caspase-3 and result in the discharge of cytochrome C from mitochondria into the cytosol, accompanied by the initiation of cell death, leading to permanent DNA damage and killing of MCF-7 cells. Furthermore, treatment with SeNPs-apigenin increased reactive oxygen species production and oxidative stress in MCF-7 cells. Our findings indicate that SeNPs-apigenin has cytotoxic potential in the treatment of breast cancer.

Abstract
BACKGROUND/AIM Copine 1 (CPNE1) is a calciumdependent phospholipid protein that has been shown to regulate the AKT serine/threonine kinase 1 (AKT) signaling pathway to mediate its function in various cell types. However, little is known about the physiological function of this protein in breast cancer cells. We aimed to investigate the prognostic and therapeutic value of CPNE1 in erb-b2 receptor tyrosine kinase 2 [human epidermal growth factor receptor 2 (HER2)]-positive and luminal A subtypes of breast cancer. MATERIALS AND METHODS Western blotting, cell viability, wound-healing and invasion assays were performed on SK-BR3 and MCF-7 breast cancer cells with forced overexpression of CPNE1. CPNE1 immunohistochemical (IHC) staining and bioinformatics analysis were performed on specimens from patients with breast cancer and compared to normal breast samples. RESULTS CPNE1 overexpression promoted AKT activation, and increased cell viability and cell motility in SK-BR3 and MCF-7 breast cancer cells. In addition, invasive capabilities of SK-BR3 cells were increased by the overexpression of CPNE1. The expression levels of CPNE1 were higher in HER2-positive and luminal A subtypes of human breast cancer tissues compared with those in adjacent normal tissues. Furthermore, CPNE1 expression was increased in RNA microarray analysis of samples from patients with breast cancer compared to normal breast samples. CONCLUSION CPNE1 may play a key role in the pathophysiology of HER2-positive and luminal A subtypes of breast cancer.

Abstract
BACKGROUND Breast cancer (BC) is the leading cause of death worldwide. The severity of BC strictly depends on the molecular subtype. The less aggressive hormone-positive subtype is treated with adjuvant endocrine therapy (AET), which causes both physical and psychological side effects. This condition strongly impacts the adherence and persistence of AET among oncologic patients. Moreover, viral infections also constitute a serious problem for public health. Despite their efficacy, antiviral agents present several therapeutic limits. Accordingly, in the present work, we investigated the antitumor and antiviral activities of Orobanche crenata Forssk. (O. crenata), a parasitic plant, endemic to the Mediterranean basin, traditionally known for its beneficial properties for human health. METHODS The MTT assay was carried out to evaluate the cytotoxic effect of O. crenata leaf extract (OCLE) on human breast cancer cells (MCF-7 and MDA-MB-231) and the primary HFF-1 cell line. The lactic dehydrogenase (LDH) assay was performed on MCF-7 cells to analyze necrotic cell death. The antioxidant effect of OCLE was evaluated by intracellular determination of the reactive oxygen species and thiol groups, by DPPH and ABTS assays. The antiviral activity of OCLE was determined against Poliovirus 1, Echovirus 9, Human respiratory syncytial virus, Adenovirus type 2 and type 5, Coxsackievirus B1 (CoxB1) and B3 (CoxB3), Herpes simplex type 1 (HSV-1) and type 2 (HSV-2), and β-Coronavirus by the plaque reduction assay. RESULTS The extract, after 24 h of incubation, did not affect MDA-MB-231 and HFF-1 cell viability. However, at the same time point, it showed a dose-dependent inhibitory effect on MCF-7 cells, with an increase in LDH release. OCLE exhibited free radical scavenging activity and significantly increased non-protein thiol levels in MCF-7 cells. OCLE effectively inhibited HSV-1, HSV-2, CoxB1, and CoxB3 replication. CONCLUSIONS The overall results showed an interesting inhibitory effect of OCLE on both MCF-7 cell survival and viral replication.

Abstract
Radiation therapy is an important component of cancer treatment scheduled for cancer patients, although it can cause numerous deleterious effects. The use of adjuvant molecules aims to limit the damage in normal surrounding tissues and enhance the effects of radiation therapy, either killing tumor cells or slowing down their growth. Melatonin, an indoleamine released by the pineal gland, behaves as a radiosensitizer in breast cancer, since it enhances the therapeutic effects of ionizing radiation and mitigates side effects on normal cells. However, the molecular mechanisms through which melatonin modulates the molecular changes triggered by radiotherapy remain mostly unknown. Here, we report that melatonin potentiated the anti-proliferative effect of radiation in MCF-7 cells. Treatment with ionizing radiation induced changes in the expression of many genes. Out of a total of 25 genes altered by radiation, melatonin potentiated changes in 13 of them, whereas the effect was reverted in another 10 cases. Among them, melatonin elevated the levels of PTEN and NME1, and decreased the levels of SNAI2, ERBB2, AKT, SERPINE1, SFN, PLAU, ATM and N3RC1. We also analyzed the expression of several microRNAs and found that melatonin enhanced the effect of radiation on the levels of miR-20a, miR-19a, miR-93, miR-20b and miR-29a. Rather surprisingly, radiation induced miR-17, miR-141 and miR-15a but melatonin treatment prior to radiation counteracted this stimulatory effect. Radiation alone enhanced the expression of the cancer suppressor miR-34a, and melatonin strongly stimulated this effect. Melatonin further enhanced the radiation-mediated inhibition of Akt. Finally, in an in vivo assay, melatonin restrained new vascularization in combination with ionizing radiation. Our results confirm that melatonin blocks many of the undesirable effects of ionizing radiation in MCF-7 cells and enhances changes that lead to optimized treatment results. This article highlights the effectiveness of melatonin as both a radiosensitizer and a radioprotector in breast cancer. Melatonin is an effective adjuvant molecule to radiotherapy, promoting anti-cancer therapeutic effects in cancer treatment. Melatonin modulates molecular pathways altered by radiation, and its use in clinic might lead to improved therapeutic outcomes by enhancing the sensitivity of cancerous cells to radiation and, in general, reversing their resistance toward currently applied therapeutic modalities.

Abstract
BACKGROUND Menopausal hormone therapy (MHT) is recommended for only five years to treat vasomotor symptoms and vulvovaginal atrophy because of safety concerns with long-term treatment. We investigated the ability of 2',3',4'-trihydroxychalcone (2',3',4'-THC) to modulate estrogen receptor (ER)-mediated responses in order to find drug candidates that could potentially prevent the adverse effects of long-term MHT treatment. METHODS Transfection assays, real time-polymerase chain reaction, and microarrays were used to evaluate the effects of 2',3',4'-THC on gene regulation. Radioligand binding studies were used to determine if 2',3',4'-THC binds to ERα. Cell proliferation was examined in MCF-7 breast cancer cells by using growth curves and flow cytometry. Western blots were used to determine if 2',3',4'-THC alters the E2 activation of the MAPK pathway and degradation of ERα. Chromatin immunoprecipitation was used to measure ERα binding to genes. RESULTS The 2',3',4'-THC/E2 combination produced a synergistic activation with ERα on reporter and endogenous genes in human U2OS osteosarcoma cells. Microarrays identified 824 genes that we termed reprogrammed genes because they were not regulated in U2OS-ERα cells unless they were treated with 2',3',4'-THC and E2 at the same time. 2',3',4'-THC blocked the proliferation of MCF-7 cells by preventing the E2-induced activation of MAPK and c-MYC transcription. The antiproliferative mechanism of 2',3',4'-THC differs from selective estrogen receptor modulators (SERMs) because 2',3',4'-THC did not bind to the E2 binding site in ERα like SERMs. CONCLUSION Our study suggests that 2',3',4'-THC may represent a new class of ERα modulators that do not act as a direct agonists or antagonists. We consider 2',3',4'-THC to be a reprogramming compound, since it alters the activity of ERα on gene regulation and cell proliferation without competing with E2 for binding to ERα. The addition of a reprogramming drug to estrogens in MHT may offer a new strategy to overcome the adverse proliferative effects of estrogen in MHT by reprogramming ERα as opposed to an antagonist mechanism that involves blocking the binding of estrogen to ERα.

Abstract
Introduction Breast cancer, as the most common malignancy among women, is shown to have a high mortality rate and resistance to chemotherapy. Research has shown the possible inhibitory role of Mesenchymal stem cells in curing cancer. Thus, the present work used human amniotic fluid mesenchymal stem cell-conditioned medium (hAFMSCs-CM) as an apoptotic reagent on the human MCF-7 breast cancer cell line. Methods Conditioned medium (CM) was prepared from hAFMSCs. After treating MCF-7 cells with CM, a number of analytical procedures (MTT, real-time PCR, western blot, and flow cytometry) were recruited to evaluate the cell viability, Bax and Bcl-2 gene expression, P53 protein expression, and apoptosis, respectively. Human fibroblast cells (Hu02) were used as the negative control. In addition, an integrated approach to meta-analysis was performed. Results The MCF-7 cells' viability was decreased significantly after 24 hours (P < 0.0001) and 72 hours (P < 0.05) of treatment. Compared with the control cells, Bax gene's mRNA expression increased and Bcl-2's mRNA expression decreased considerably after treating for 24 hours with 80% hAFMSCs-CM (P = 0.0012, P < 0.0001, respectively); an increasing pattern in P53 protein expression could also be observed. The flow cytometry analysis indicated apoptosis. Results from literature mining and the integrated meta-analysis showed that hAFMSCs-CM is able to activate a molecular network where Bcl2 downregulation stands in harmony with the upregulation of P53, EIF5A, DDB2, and Bax, leading to the activation of apoptosis. Conclusion Our finding demonstrated that hAFMSCs-CM presents apoptotic effect on MCF-7 cells; therefore, the application of hAFMSCs-CM, as a therapeutic reagent, can suppress breast cancer cells' viabilities and induce apoptosis.

Abstract
Anticancer drug cytarabine, has been widely used for treating haematological malignancies while it has minimal activity against solid tumours, which demands continuous infusion leading to high dose cytarabine toxicity. In this study, folate conjugated chitosan nanoparticles (FCCNP) were used for targeted delivery of cytarabine in breast adenocarcinoma cell lines by making use of the overexpressed folate receptors on the surface of MCF-7. Folate was conjugated to chitosan using carbodiimide. FCCNPs show spherical morphology with a size of<50 nm. Zeta potential of + 45.2 mV and PDI of 0.98 from DLS measurement confirms a stable monodisperse nanoformulation. Cytotoxicity was studied in folate receptor positive, MCF-7 and folate receptor negative, A-549 cell lines. Increased cellular uptake of the drug incorporated nanoparticles was confirmed in MCF-7 cells with fluorophore, squaraine 650 compared to A-549 cells. The relative fold of expression of genes involved in apoptosis such as bax, cyt c and cas 9 were upregulated. The present in vitro study confirms improved cytotoxicity of cytarabine folate conjugated chitosan nanoparticles in MCF-7 cells.
