Abstract
Currently, there is still a lack of effective carriers with minimal side effects to deliver therapeutic miRNA. Thus, it is crucial to optimize novel drug delivery systems. MiR-375 has proven superior therapeutic potency in Hepatocellular carcinoma (HCC). The purpose of this study was to fabricate 2 novel and smart nano-carriers for the transportation efficiency of miR-375 in HCC cells and enhance its anti-tumor effects. We established the miR-375 construct through the pEGP- miR expression vector. Two nano-carriers of solid/liquid lipids and chitosan (CS) were strategically selected, prepared by high-speed homogenization, and optimized by varying nano-formulation factors. Thus, the two best nano-formulations were designated as F1 (0.5% CS) and F2 (1.5% CS) and were evaluated for miR-375 conjugation efficiency by gel electrophoresis and nanodrop assessment. Then, physio-chemical characteristics and stability tests for the miR-375 nano-plexes were all studied. Next, its efficiencies as replacement therapy in HepG2 cells have been assessed by fluorescence microscopy, flow cytometry, and cytotoxicity assay. The obtained data showed that two cationic nanostructured solid/liquid lipid carriers (NSLCs); F1 and F2 typically had the best physio-chemical parameters and long-term stability. Moreover, both F1 and F2 could form nano-plexes with the anionic miR-375 construct at weight ratios 250/1 and 50/1 via electrostatic interactions. In addition, these nano-plexes exhibited physical stability after three months and protected miR-375 from degradation in the presence of 50% fetal bovine serum (FBS). Furthermore, both nano-plexes could simultaneously deliver miR-375 into HepG2 cells and they ensure miR re-expression even in the presence of 50% FBS compared to free miR-375 (p-value < 0.001). Moreover, both F1 and F2 alone significantly exhibited minimal cytotoxicity in treated cells. In contrast, the nano-plexes significantly inhibited cell growth compared to free miR-375 or doxorubicin (DOX), respectively. More importantly, F2/miR-375 nano-plex exhibited more anti-proliferative activity in treated cells although its IC50 value was 55 times lower than DOX (p-value < 0.001). Collectively, our findings clearly emphasized the multifunctionality of the two CS-coated NSLCs in terms of their enhanced biocompatibility, biostability, conjugation, and transfection efficiency of therapeutic miR-375. Therefore, the NSLCs/miR-375 nano-plexes could serve as a novel and promising therapeutic strategy for HCC.

Abstract
BACKGROUND miR-210, a key hypoxamiR, regulates hypoxia and inflammation-linked hypoxia. Systemic lupus erythematosus (SLE), a chronic autoimmune disease, is responsible for many pathological disorders, including photosensitivity. OBJECTIVE This study aimed to find the correlation between circulating miR-210/HIF-1α levels and photosensitivity in SLE patients and other SLE-associated pathological complications in a single-center case-control study. METHODS The study population comprised 104 SLE Egyptian patients with photosensitivity, 32 SLE patients without photosensitivity, and 32 healthy subjects. SLE activity was assessed for all patients using the SLE Disease Activity Index (SLEDAI). Clinical complications/manifestations and hematological/serological analyses were recorded. HIF-α concentration was investigated by ELISA, and miR-210 expression was analyzed by qRT-PCR. RESULTS The results revealed that circulating miR-210 was significantly increased in the SLE/photosensitivity group versus the SLE and control groups. The additional occurrence of malar rash, oral ulcers, renal disorders, or hypertension resulted in a higher expression of miR-210. SLEDAI activity status showed no effect on miR-210. Erythrocyte sedimentation rate, white blood cells, hemoglobin, platelets, patient age, and disease duration were positively correlated with circulatory miR-210. HIF-α concentration was significantly induced in the SLE/photosensitivity group versus the SLE and control groups. In SLE/photosensitivity, the presence of renal disorders and hypertension resulted in the highest HIF-α concentrations. A strong positive correlation was recorded between HIF-α concentration and circulatory miR-210 in SLE/photosensitivity patients (r = 0.886). CONCLUSION The dysregulation of circulating miR-210/HIF-1α levels in SLE/ photosensitivity patients is controlled by the presence of additional pathological complications, and results suggest that the hypoxia pathway might interact positively with the pathogenesis and disease progression of SLE.

Abstract
BACKGROUND Chia seed is an oil seed with multiple biological activities. Doxorubicin is effective chemotherapy for liver cancer. Resistance and adverse effects are doxorubicin limitations. OBJECTIVE This study aimed to investigate the effect of chia seeds oil (CSO) on the resistance of HepG2 cells to liposomal-doxorubicin (DOX). METHODS The objective were investigated through measuring cytotoxicity, doxorubicin-metabolizing enzyme Cytochrome P450 3A4 (CYP-3A4), multidrug resistance-associated protein (MRP1), and the expression of multiple tumor suppressor microRNAs. RESULTS The findings indicated that low concentration of CSO increased HepG2 cells' sensitivity to DOX, as concluded from its higher cytotoxicity. DOX-induced mRNAs of CYP-3A4 and MRP1 and their protein levels. CSO inhibited both in DOX-treated cells. CSO-induced tumor suppressor miRNAs. Doxorubicin inhibited miR-122 and let-7/b/e expression, while it led to overexpression of let- 7a. CSO/DOX upregulated let-7/b/e, miR-34a, and miR-122 (which inhibits MRP1) and downregulated let-7a, which may lead to increased apoptosis. CONCLUSION CSO effectively re-sensitized HepG2 cells to liposomal-doxorubicin via inhibiting MRP1 and CYP-3A4, which may increase in vivo doxorubicin bioavailability and decrease its therapeutic dose to diminish its adverse effects.

Abstract
OBJECTIVE MicroRNAs are fine regulators for gene expression during the post-transcriptional stage in many autoimmune diseases. HypoxamiRs (miR-210 and miR-21) play an important role in hypoxia and in inflammation-associated hypoxia. Systemic lupus erythematosus (SLE) is a chronic systemic autoimmune disease that would potentiate many pathological complications, including hemolytic anemia. This study aimed to investigate the role of hypoxamiRs in SLE/hemolytic anemia patients. METHODS This work was designed to analyze the circulating levels of↱ the miR-210 and miR-21 expressions and hypoxia-inducible factor-1α (HIF-α) in SLE/hemolytic anemia patients. SLE activity was evaluated for all patients by SLE Disease Activity Index (SLEDAI). Clinical manifestations/complications and serological/hematological investigations were reported. HIF-α concentration was assayed by ELISA and expression of miR-21 and miR-210 was analyzed by qRT-PCR. RESULTS The results indicated that the fold change of the miR-210/miR-21 expressions in plasma was significantly elevated in SLE/hemolytic anemia patients. A strong positive correlation between the miR-210 and miR-21 expression levels was also recorded. Among the associated-disease complications, hypertension, arthritis, oral ulcers, and serositis were associated with a high circulating miR-210 expression, while the occurrence of renal disorders was associated with the increased miR-21 expression. Furthermore, the HIF-α level was remarkably elevated in SLE/hemolytic anemia patients. A high positive correlation was recorded between the HIF-α concentration and miR-210/miR-21 expression levels. The occurrence of oral ulcers, arthritis, and hypertension was associated with the increased HIF-α concentration. On the other hand, SLEDAI and white blood cell count were positively correlated with miR-21/ miR-210. The erythrocyte sedimentation rate was positively correlated with miR-21. CONCLUSION The dysregulation of the circulating miR-210/miR-210/HIF-1α levels in SLE/hemolytic anemia patients advocated that the hypoxia pathway might have an essential role in the pathogenesis and complications of these diseases.

Abstract
Cyclophosphamide (CP) is a mutagen that is used in cancer chemotherapy, due to its genotoxicity and as an immunosuppressive agent. Thalidomide (TH) is another cancer chemotherapeutic drug. In this study, the cytogenotoxicity and hypoxia modulatory activities of two phthalimide analogs of TH have been evaluated with/without CP. Both analogs have increased CP-stimulated chromosomal aberrations than those induced by TH, including gaps, breaks/fragments, deletions, multiple aberrations, and tetraploidy. The analogs have elevated the cytotoxic effect of CP by inhibiting the mitotic activity, in which analog 2 showed higher mitosis inhibition. CP has induced binucleated and polynucleated bone marrow cells (BMCs), while micronuclei (MN) are absent. TH and analogs have elevated the CP-stimulated binucleated BMCs, while only analogs have increased the CP-induced polynucleated BMCs and inhibited the mononucleated BMCs. MN-BMCs were shown together with mononucleated, binucleated, and polynucleated cells in the CP group. Both analogs have elevated mononucleated and polynucleated MN-BMCs, whereas in presence of CP, TH and analogs have enhanced mononucleated and binucleated MN-BMCs. The analogs significantly induce DNA fragmentation in a comet assay, where analog 1 is the strongest inducer. The treatment of mice with CP has resulted in a high hypoxia status as indicated by high pimonidazole adducts and high HIF-1α and HIF-2α concentrations in lymphocytes. Analogs/CP-treated mice showed low pimonidazole adducts. Both analogs have inhibited HIF-1α concentration but not HIF-2α. Taken together, the study findings suggest that both analogs have a higher potential to induce CP-genotoxicity than TH and that both analogs inhibit CP-hypoxia via the HIF-1α-dependent mechanism, in which analog 1 is a more potent anti-hypoxic agent than analog 2. Analog 1 is suggested as an adjacent CP-complementary agent to induce CP-genotoxicity and to inhibit CP-associated hypoxia.

Abstract
Indocyanine green (ICG) is a nontoxic registered photosensitizer used as a diagnostic tool and for photodynamic therapy (PDT). Hypoxia is one the main factors affecting PDT efficacy. Perfluorodecalin emulsion (Perftoran®) is a known oxygen carrier. This study investigated the effect of Perftoran® on ICG/PDT efficacy in presence and absence of Perftoran®via evaluation of phototoxicity by MTT; hypoxia estimation by pimonidazole, HIF-1α/β by ELISA, and 17 miRNAs (tumor suppressors, oncomiRs, and hypoxamiRs) were analyzed by qPCR. Compared to ICG/PDT, Perftoran®/ICG/PDT led to higher photocytotoxicity, inhibited pimonidazole hypoxia adducts, inhibited HIF-1α/β concentrations, induced the expression of tumor-suppressing miRNAs let-7b/d/f/g, and strongly inhibited the pro-hypoxia miRNA let-7i. Additionally, Perftoran®/ICG/PDT suppressed the expression of the oncomiRs miR-155, miR-30c, and miR-181a and the hypoxamiRs miR-210 and miR-21 compared to ICG/PDT. In conclusion, Perftoran® induced the phototoxicity of ICG/PDT and inhibited ICG/PDT-hypoxia via suppressing HIF-α/β, miR-210, miR-21, let-7i, miR-15a, miR-30c, and miR-181a and by inducing the expression of let-7d/f and miR-15b.

Abstract
Sargassum dentifolium, (Turner) C. Agarth, 1820, is an edible brown alga collected from red seashores, Egypt. Oral tongue squamous cell carcinoma (OTSCC) is an aggressive malignancy. Hypoxia leads to chemotherapeutic resistance. This work aimed to explore the anti-hypoxia effect of water-soluble polysaccharide fractions of S. dentifolium (SD1-SD3) in CAL-27 OTSCC cells. Cell cytotoxicity assay (MTT); cell death mode (DNA staining); total hypoxia (pimonidazole), HIF-1α (ELISA and immunocytochemistry), HIF-1β (ELISA), and hsa-miRNA-21-5p and hsa-miRNA-210-3p (qRT-PCR) were investigated. SD1 and SD2 showed a cytotoxic effect due to apoptosis. SD2 and SD3 decreased total cell hypoxia, inhibited miR-210 (p < 0.001 and p < 0.01), miR-21 (p < 0.01 and p < 0.05), and HIF-1α (p < 0.01 and p < 0.05), respectively. However, only SD3 suppressed HIF-1β (p < 0.05). In conclusion, SD2 showed a potential anti-hypoxia effect through amelioration of HIF-1α regulators, which may help in decreasing hypoxia-induced therapeutic resistance.

Abstract
Perftoran® (perfluorodecalin) is an oxygen carrier, and carboplatin is a common chemotherapy drug used worldwide for lung cancer treatment. Hypoxia is one of the factors that induce resistance of lung cancer cells to carboplatin. This study explored the role of Perftoran®, as an oxygen carrier, in lowering the resistance of lung cancer cells to carboplatin through suppression of hypoxia pathway mediators. The effect of Perftoran® on the resistance of human lung cancer A549 cells to carboplatin was investigated through the evaluation of cytotoxicity by MTT, cell death mode by dual DNA staining, DNA damage by comet assay, DNA platination (DNA/carboplatin adducts) by atomic absorption spectroscopy, hypoxia degree by pimonidazole, HIF-1α/HIF-2α concentrations by ELISA, expression of miRNAs (hypoxamiRs miR-210, miR-21, and miR-181a) by qRT-PCR, and the content of drug resistance transporter MRP-2 by immunocytochemical staining. Results indicated that compared to carboplatin, Perftoran®/carboplatin decreased cell resistance to carboplatin by potentiating its cytotoxicity using only 45% of carboplatin IC50 and inducing apoptosis. Perftoran® induced DNA platination and DNA damage index in cells compared to carboplatin alone. Moreover, compared to treatment with carboplatin alone, co-treatment of cells with Perftoran® and carboplatin inhibited cellular pimonidazole hypoxia adducts, diminished HIF-1α/HIF-2α concentrations, suppressed hypoxamiR expression, and decreased MRP-2. In conclusion, Perftoran® inhibited resistance of lung cancer cells to carboplatin through the inhibition of both hypoxia pathway mediators and the drug resistance transporter MRP-2 and through the induction of DNA/carboplatin adduct formation.

Abstract
BACKGROUND α-Solanine is a natural toxic glycoalkaloid produced in some species of the Solanaceae family with antiproliferative activity in various cancers. OBJECTIVE This study aimed to investigate the effect of α-solanine on the oxidative stress status in human hepatocellular carcinoma HepG2 cells and to evaluate its influence on microRNAs (miRNAs) associated with oxidative stress and NF-κB regulation. METHODS The prooxidant effect of α-solanine was tested by the decay rate of the fluorescent probe, β-phycoerythrin, and by measuring malondialdehyde, reduced Glutathione, catalase, and superoxide dismutase following treatment of HepG2 cells with low doses of α-solanine. Immunocytochemical techniques were used to detect mitochondrial membrane potential (ΔΨm) and NF-κB protein. The gene expression of NF-κB and miRNAs was evaluated by real-time PCR. RESULTS α-Solanine is a prooxidant that causes a rapid decay in the fluorescence intensity of β-phycoerythrin. It induces oxidative stress-related alterations such as increased lipid peroxidation and reduced antioxidant markers. Oxidative stress induced by α-solanine was mediated by decreased ΔΨm, increased NF-κB expression, upregulation of miRNAs that control oxidative stress by regulating the NF-κB pathway, and downregulation of oncogenic miRNAs that inhibit the NF-κB pathway. CONCLUSION α-Solanine-induced oxidative stress is mediated by alterations in the NF-κB pathway with a detected crosstalk between α-solanine treatment and the expression of oxidative stress-responsive miRNAs.

Abstract
BACKGROUND Shortage of oxygen is a common condition for residents of high-altitude (HA) areas. In mammals, hemoglobin (Hb) has four derivatives: oxyhemoglobin (Hb-O2), carboxyhemoglobin (Hb-CO), sulfhemoglobin (Hb-S), and methemoglobin (Met-Hb). In HA areas, aberrant physiological performance of blood hemoglobin is well-established. OBJECTIVE The study aimed to investigate the influence of 30 days of HA residence on rabbits' total Hb, Hb derivatives, Hb autooxidation rate, and antioxidant enzymes in comparison to low-altitude control rabbits. Further, the study aimed to investigate the effect of antioxidant-rich Angelica archangelica and/or Ginkgo biloba extracts on the same parameters in HA-resident rabbits. METHODS Rabbits subjected to 30 days of HA residence were compared to low-altitude control rabbits. HA-residence rabbits were then orally administered 0.11 g/kg b.wt. of Angelica archangelica and/or Ginkgo biloba extract for 14 days. Hb derivatives and Hb autooxidation rate were measured spectrophotometrically. Antioxidant enzymes were estimated using specialized kits. RESULTS Compared to low-altitude rabbits, 30-day HA-residence rabbits showed a noticeable increase (p<0.05) in Hb-O2 and Hb-CO concentration. In addition, Met-Hb concentration, autooxidation rate of Hb molecules, and activities of superoxide dismutase (SOD) and glutathione peroxidase (GPx) exhibited a remarkable increase in HA-residence rabbits (p<0.01), reflective of rapid ROS generation. In HA-residence rabbits, both individual and combined treatment with antioxidant-rich extracts for 14 days resulted in recovery to near-normal functional levels of Hb-O2 and Met-Hb, Hb autooxidation rate, and activities of SOD and GPx, while only combined treatment led to Hb-O2 recovery. CONCLUSION The findings suggest that functional Hb levels may be recovered by oral administration of A. archangelica, G. biloba, or combined treatments. In conclusion, oxidative stress due to living in HA areas may be avoided by supplementation with natural antioxidants.

Abstract
BACKGROUND Abelmoschus esculentus (AE) (okra), is an edible plant used in many food applications. OBJECTIVE This study explored whether sulfated AE (SAE) has promising cancer chemopreventive activities that may recommend it as a functional food supplement instead of (or in addition to) AE for the population at risk of cancer and in the health food industry. METHODS Cytochrome P450-1A (CYP1A) was estimated by fluorescence enzymatic reaction, using β-naphthoflavone-treated cells (CYP1A inducer). Peroxyl and hydroxyl radical scavenging was assayed by an oxygen radical absorbance capacity assay. Flow cytometry was used to analyze apoptosis/necrosis in MCF-7 cells, cell cycle phases in MCF-7 cells, and macrophage binding to fluorescein isothiocyanate-lipopolysaccharide (FITC-LPS). Nitric oxide was determined by Griess assay in LPS-stimulated macrophages, and cytotoxicity was determined by MTT assay. Diethylnitrosamine (DEN) was used to induce hepatic tumor initiation in rats. Placental glutathione-S-transferase (GSTP; an initiation marker) was stained in a fluorescence immunohistochemical analysis of liver sections, and histopathological changes were examined. RESULTS SAE exhibited strong antitumor initiation and antitumor promotion activities. It suppressed CYP1A, scavenged peroxyl and hydroxyl radicals, induced macrophage proliferation, suppressed macrophage binding to FITC-LPS, inhibited nitric oxide generation, showed specific cytotoxicity to human breast MCF-7 adenocarcinoma cells, and disturbed the cell cycle phases (S and G2/M phases) in association with an increased percentage of apoptotic/necrotic MCF-7 cells. Over a short time period, DEN stimulated liver cancer initiation, but SAE treatment reduced the DEN-induced histopathological alterations and inhibited CYP1A and GSTP. CONCLUSION SAE extract has the potential for use as an alternative to AE in health foods to provide cancer chemoprevention in populations at risk for cancer.

Abstract
AIM The clinical application of cisplatin is limited by severe side effects associated with high applied doses. The synergistic effect of a combination treatment of a low dose of cisplatin with the natural alkaloid α-solanine on human hepatocellular carcinoma cells was evaluated. METHODS HepG2 cells were exposed to low doses of α-solanine and cisplatin, either independently or in combination. The efficiency of this treatment modality was evaluated by investigating cell growth inhibition, cell cycle arrest, and apoptosis enhancement. RESULTS α-solanine synergistically potentiated the effect of cisplatin on cell growth inhibition and significantly induced apoptosis. This synergistic effect was mediated by inducing cell cycle arrest at the G2/M phase, enhancing DNA fragmentation and increasing apoptosis through the activation of caspase 3/7 and/or elevating the expression of the death receptors DR4 and DR5. The induced apoptosis from this combination treatment was also mediated by reducing the expression of the anti-apoptotic mediators Bcl-2 and survivin, as well as by modulating the miR-21 expression. CONCLUSION Our study provides strong evidence that a combination treatment of low doses of α-solanine and cisplatin exerts a synergistic anticancer effect and provides an effective treatment strategy against hepatocellular carcinoma.

Abstract
BACKGROUND MicroRNA modulation therapy has shown great promise to treat hepatocellular carcinoma (HCC), however Efficient tissue-specific and safe delivery remains a major challenge. OBJECTIVE We sought to develop an inorganic-organic hybrid vehicle for the systemic delivery of the tumor suppressor miR-34a, and to investigate the efficiency of the delivered miR-34a in the treatment of HCC in vitro and in vivo. METHODS In the present study, pEGP-miR cloning and expression vector, expressing miR-34a, was electrostatically bound to polyethyleneimine (PEI), and then loaded onto ZSM-5 zeolite nanoparticles (ZNP). Qualitative and quantitative assessment of the transfection efficiency of miR-34a construct in HepG2 cells was applied by GFP screening and qRT-PCR, respectively. The expression of miR-34a target genes was investigated by qRT-PCR in vitro and in vivo. RESULTS ZNP/PEI/miR-34a nano-formulation could efficiently deliver into HepG2 cells with low cytotoxicity, indicating good biocompatibility of generated nanozeolite. Furthermore, five injected doses of ZNP/PEI/miR-34a nano-formulation in HCC induced male Balb-c mice, significantly inhibited tumor growth, and demonstrated improved cell structure, in addition to a significant decrease in alphafetoprotein level and liver enzymes activities, as compared to the positive control group. Moreover, injected ZNP/PEI/miR-34a nano-formulation led to a noticeable decrease in the CD44 and c-Myc levels. Results also showed that ZNP/PEI/miR-34a nano-formulation inhibited several target oncogenes including AEG-1, and SOX-9, in vitro and in vivo. CONCLUSION Our results suggested that miR-34a is a powerful candidate in HCC treatment and that AEG-1 and SOX-9 are novel oncotargets of miR-34a in HCC. Results also demonstrated that our nano-formulation may serve as a candidate approach for miR-34a restoration for HCC therapy, and generally for safe gene delivery.

Abstract
Enterolobium cyclocarpum (EC) is an edible plant and a gum source for food industries. Its sulfated polysaccharide extract (SEC) was examined for cancer chemopreventive properties to estimate its anti-tumor activity. The modulation of carcinogen metabolism and the antioxidant activity revealed that SEC is a potent tumor anti-initiator since it inhibited cytochrome P450-1A (CYP1A) and induced carcinogen detoxification enzyme glutathione-S-transferase. SEC is also a weak scavenger for hydroxyl and peroxyl radicals. SEC was found to modulate macrophage functions into an anti-inflammatory pattern, where it enhanced macrophage proliferation and phagocytosis of fluorescein isothiocyanate-lipopolysaccharide (FITC-LPS). In addition, SEC strongly inhibited the nitric oxide (NO) generation in LPS-stimulated macrophages and induced the binding affinity of FITC-LPS to macrophages. SEC exhibited specific cytotoxicity against human hepatocellular Hep G2 carcinoma cells. SEC disturbed the cell cycle phase, as indicated by the concomitant arrest in S- and G2/M-phases that was associated with necrosis induction. A short-term initiation model for liver cancer was prepared using diethylnitrosamine (DEN) in rats. SEC inhibited the DEN-histopathological findings and reduced both CYP1A and the tumor initiation marker placental glutathione S-transferase (GSTP). Taken together, SEC could be used as an alternative gum in health food industries to provide cancer prevention in high-risk populations.

Abstract
Lapatinib, one of the tyrosine kinase inhibitors (TKIs), is used to reduce epidermal growth factor family proteins overexpression. This study aims to assess the cytotoxic and genotoxic effects of lapatinib on the triple negative breast cancer cell line "MDA-MB-231". We investigated the cytotoxicity of lapatinib by MTT assay, mode of cell death using apoptosis-necrosis assay, DNA damage using micronucleus test, EGFR protein expression by immunocytochemistry, and assessed its effect on EGFR (7p11.2 locus) and TP53 (17p13 locus) genes using interphase-FISH technique. Lapatinib induced cytotoxicity on MDA-MB-231 cell line by elevating the concentration and its IC50 value was 32.5 μM after 24 h. Lapatinib increased apoptotic cells and micronuclei in binucleated cells gradually by increasing the concentration for 24 h. The EGFR protein expression was reduced by double fold that expressed in non-treated cells. Lapatinib enhanced deletion of EGFR gene signals highly significantly from the lowest concentration. Alternatively, lapatinib amplified signals of TP53 gene effectively by raising the concentration. In conclusion, lapatinib induced cytotoxic and genotoxic effects on MDA-MB-231 cell line. However, laptinib reduced the EGFR protein expression and EGFR signals, it raised the apoptotic cells and TP53 gene signals, which triggered extensive DNA damage. Therefore, lapatinib is an effective TKI in triple negative breast cancer cells as elucidated by its mode of cell death.

Abstract
BACKGROUND TNFRSF13B, TACI, is a member of the TNF receptor superfamily; it plays a key role in cancer cell proliferation and progression. METHOD Influence of silencing of human cytokine receptors on cell viability was screened by Luminescent Cell Viability Assay, after transfection of the siRNA library to find the maximum cell death superhits in both triple-negative MDA-MB-231 and double-positive MCF7 breast cells. The mode of cell death was investigated by dual DNA fluorescence staining. The expression of mRNAs of TACI, BAFF, BAFF-R, and APRIL was explored by qPCR. Immunocytofluorescence analysis was used to evaluate changes in TACI, Bcl-2, TNFR2, cyclin-D2, and PCNA. NF-kB p65, cell cycle, and necrosis/apoptosis (late and early) were analyzed by flow cytometry. RESULTS TACI is the most potent cytotoxic superhit resulted from high-throughput screening of the siRNA library, in both types of cells. Our findings indicated that silencing receptor TACI in both types of breast cancer cells led to significant cell death, after different intervals from siRNA transfection. Cell death mediators (TNFR2, Bcl-2, and NF-κB) were significantly decreased after TACI silencing. The key factors for cell division (Cyclin-D2 and PCNA) were significantly increased in silenced cells of both types but the cell cycle was arrested before the completion of mitosis. Expression of BAFF, BAFF-R and APRIL mRNA in TACI-silenced cells showed significant upregulation in MDA-MB-231 cells, while only BAFF-R and APRIL showed significant downregulation in MCF7 cells. CONCLUSION TACI silencing can be a new and promising therapeutic target for mesenchymal-stem like triple-negative breast cancer subtype.

Abstract
Early detection of colorectal cancer and monitoring the progress in colon carcinogenesis stages is essential to reduce mortality. Therefore, there is continuous search for noninvasive biomarkers with high stability and good sensitivity and specificity. miRNAs have attracted attention as promising biomarkers as they are stably expressed in circulation. The aim of our study is to evaluate the aberrant expression of circulating miRNAs during the stepwise progress of colitis-associated colon cancer. This was accomplished through assessing the expression levels of five miRNAs (miR-141, miR-15b, miR-17-3p, miR-21, and miR-29a) in serum and their corresponding tissue samples through the different cycles of colorectal carcinogenesis cascade using the azoxymethane/dextran sulfate sodium murine model. We also compared the diagnostic performance of these selected miRNAs with the conventional tumor biomarkers CEA and CA 19-9. The results of our study revealed that the expression levels of those miRNAs were dynamically changing in accordance with the tumor development state. Moreover, their aberrant expression in serum was statistically correlated with that in tissue. Our data also revealed that serum miR-15b, miR-21, and miR-29a showed the best performance in terms of diagnostic power. Our findings highlight the efficiency of these circulating miRNAs not only for early diagnostics purposes, but also for monitoring progress in the colorectal carcinogenesis process, and therefore encouraging integrating these noninvasive biomarkers into the clinical diagnostic settings beside the traditional diagnostic markers for accurate screening of the early progress of colon carcinogenesis.

Abstract
Phytochemical and biological investigation of the leaves of Cassia petersiana afforded two new chromones (1, 2), in addition, to the known glyceryl-1-hexacosanoate (3) and stigmasterol-3-O-β-D-glucoside (4). The structures of the compounds were determined by comprehensive NMR studies, including DEPT, COSY, HMQC, HMBC and IR spectroscopy and MS. 1–4 were investigated against different types of cell lines, including solid tumor cells (Hep-G2, and MCF-7 cells) and leukemia (1301) cells for their cytotoxic effects. 1–3 possessed a dose-dependent cytotoxic effect against Hep-G2 cells, but in relatively high concentrations; 4 was the most cytotoxic with the lowest IC50 value of 82.7 μM. The calculated IC50 values against MCF-7 cells were 112.2 μM, 143.7 μM, 68.1 μM, and 114.3 μM for 1, 2, 3, and 4, respectively. The alteration in the macrophage proliferation index, using Raw 264.7 cells, was monitored. 1 and 3 were the highest stimulators of macrophage proliferation in a dose-dependent manner, whereas 2 and 4 showed a peak point of stimulation at 20 μM. The effect of these compounds on pre-induced NO was explored. 1–4 inhibited the LPS-induced NO, with inhibition percentages of 80.5%, 89.3%, 82.1%, and 92.1%, respectively, at a concentration of 20 μM. The antioxidant capacity of 1–4, using the DPPH assay was also investigated. 1–3 possessed weak scavenging activity; while 4 had an effective SC50 value as low as 36 μM. These results indicated that 4 possessed the highest anti-tumor, immunoproliferative, macrophage proliferation, anti-inflammatory, and antioxidant activities.

Abstract
A new phenylethanoid, 2-(3,4-dihydroxyphenyl)ethyl-,2-O-(6-deoxy-α-L-mannopyranosyl-,4-(3,4-dihydroxyphenyl)-2-propenoate)-β-D-glucopyranoside (3) and a novel monoterpene alkaloid, 5-hydroxy-skytanthine hydrochloride (8), along with eleven known compounds have been isolated from Tecoma stans Juss. fruits and flowers. 4-O-E-Caffeoyl-α-L-rhamnopyranosyl-(1′→3)-α/β-D-glucopyranose (1), E/Z-acetoside (2), isoacetoside (4), rutin (5), luteolin 7-O-β-D-neohespridoside (6), luteolin 7-O-β-D-glucopyranoside (7) and sucrose (9) were isolated from the fruits, while luteolin 7-O-β-D-glucuronopyranoside (10), diosmetin 7-O-β-D-glucuronopyranoside (11), diosmetin 7-O-β-D-glucopyranoside (12), diosmetin 7-O-β-D-glucuronopyranoside methyl ester (13), and 2 from the flowers. Their structures were determined on the basis of chemical and spectroscopic evidence. It was found that the extract of T. stans fruits and compounds 1, 2 and 4 possess strong scavenging activity to DPPH, peroxyl and hydroxyl radicals. Unlike 4, which potentially induced NO generation in bacterial lipopolysaccharide-stimulated Raw murine macrophages (RAW 264.7), the extract, and compounds 1, 2, and 8 significantly inhibited NO generation. The extract, and compounds 2 and 4 exhibited a cytotoxic effect on human hepatocarcinoma cells (Hep-G2), while the extract, 2 and 8 were potent growth inhibitors of human breast carcinoma (MCF-7). Also, 1 and 2 were remarkable growth inducers of human lymphoblastic leukemia cells (1301), whereas the extract, 2, and 8 stimulated the macrophage proliferation rate.

Abstract
The modulatory role of the Bifidobacterium longum (BL), isolated from women breast milk, on some oncogenic and tumor suppressor miRNAs as well as IL-1β and IL6 targeted-miRNAs was investigated using murine colorectal cancer (CRC) induced on the top of inflammatory ulcerative colitis model. The investigation of the oncomiRs miR-21a and miR-155, which regulate IL-6 and IL-1β expression, indicated that both was depressed by BL-administration in healthy and in CRC-mice. BL-administration induced the tumor suppressor miRNAs (miR-145 and miR-15a) expression in both of the healthy and in CRC-mice. The miR-146a expression, which regulates both of IL-1β and IL-6 expression, was decreased after the BL-administration in both of the healthy and in CRC-mice. In CRC-mice, NF-Kb concentration was elevated, however this NF-Kb induction was diminished after the treatment with BL. BL highly enhanced the IL-1β and IL-6 mRNA and protein concentrations in healthy mice. The administration of BL to CRC-mice resulted in a dramatic increase in IL-1β mRNA and IL-1β concentration, which in contrast was accompanied with a decrease in the IL-6 mRNA and IL-6 concentration. BL-administration resulted in a drop in the aberrant crypt foci number in CRC-mice and increased necrosis and fibrosis of the colon cells. The modulatory influence of B. longum on microRNAs may provide an important therapeutic impact in CRC through inhibition of the proliferation, invasion, apoptosis, and cell cycle of tumor cells.

Abstract
Local delivery of antibiotic into injured bone is a demand. In this work, different scaffolds of chitosan (C) with or without bioactive glass (G) were prepared using the freeze-drying technique in 2:1, 1:1, and 1:2 weight ratios. Chitosan scaffolds and selected formulas of chitosan to bioglass were loaded with ciprofloxacin in 5%, 10%, and 20% w/w. Scaffold morphology showed an interconnected porous structure, where the glass particles were homogeneously dispersed in the chitosan matrix. The kinetic study confirmed that the scaffold containing 1:2 weight ratio of chitosan to glass (CG12) showed optimal bioactivity with good compromise between Ca and P uptake capacities and Si release rate. Chitosan/bioactive glass scaffolds showed larger t 50 values indicating less burst drug release followed by a sustained drug release profile compared to that of chitosan scaffolds. The cell growth, migration, adhesion, and invasion were enhanced onto CG12 scaffold surfaces. Samples of CG12 scaffolds with or without 5% drug induced vascular endothelial growth factor (VEGF), while those containing 10% drug diminished VEGF level. Only CG12 induced the cell differentiation (alkaline phosphatase activity). In conclusion, CG12 containing 5% drug can be considered a biocompatible carrier which would help in the localized osteomyelitis treatment.

Abstract
Tubulin targeting agents have received considerable interest as a potential tumor-selective vascular disrupting agents, which represent another avenue for cancer growing therapeutic opportunities. Hence, the present study was conducted to investigate the anti-tumor activity of Combretastatin A-4 phosphate (CA4-P) and vincristine against hepatocellular carcinoma in rats, by individual administration and in combination. In vitro study was conducted using human hepatocellular carcinoma cell lines, showed that CA4-P and vincristine have a potent cell cytotoxic and tubulin inhibitory effect. In addition, a remarkable synergistic effect was observed by the simultaneous application of both drugs. Whereas in vivo study was conducted using model of rat liver cancer initiated with DENA and promoted by CCl4, showed that CA4-P and vincristine were significantly decreased liver relative weight, number of hepatic nodules and there relative volumes, tubulin content of the hepatic tissue, GSH and AFP. On the other hand, co-administration of both drugs exhibited significant further decrements in these parameters. Whereas a marked increase in MDA, carbonyl content and TNF-α inside hepatic tissue were observed in the treated groups and these increments were more prominent by co-administration of both drugs. In conclusion CA4-P showed a potential anti-cancer activity against hepatocellular carcinoma and this effect was greatly enhanced by co-administration with vincristine. Additionally, our new findings provided an important evidence that the anticancer activity of drugs with a narrow therapeutic window such as vincristine can be greatly improved by its co-administration with CA4-P providing more enhanced activity with less side effects.

Abstract
This work pointed out the anti-cancer effect of ferrimagnetic glass ceramic nanocomposites (CaO-ZnO-Fe2O3-SiO2), which contain high amount of magnetite (∼60%), crystallite size <100nm, and different nucleating agents on bone cancer Saos-2 cells. The cell viability was inhibited by FH and FW to <50% and <25%, respectively, with/without magnetism, and both also reduced mitochondrial transmembrane potential (ΔYm), with/without magnetism (no influence of magnetism). Histone deacetylase (HDAC) activity was inhibited by FH, FW, and FHPNT, with/without magnetism. FHP3/magnetism resulted in HDAC inhibition. In absence of magnetism, FH and FW increased both necrotic and apoptotic cell death, while FW/magnetism induced late apoptosis. DNA fragmentation was increased by FH- and FW-treatment, with/without magnetism. At the same time, FW and FH/magnetism can efficiently induce the intrinsic apoptotic pathway in Saos-2 cells, whereas FW with/without magnetism and FH/magnetism enhanced cytochrome-C release. Similarly, caspase-7 activity was elevated by FH and FW, with/without magnetism. However, the presence of P2O5 in the composition of the nanocomposites inhibited their apoptotic properties and diminished their anti-cancer activity.

Abstract
BACKGROUND The photothermal properties of gold nanoparticles (GNPs) are promising therapeutic modality for cancer. The study objective is to evaluate the therapeutic effect of the prepared PEGylated gold nano-semicubes (PEG-GNSCs) in skin cancer. The synthesized PEG-GNSCs were intermediate between cubic and rod shapes (low aspect ratio- rods). METHODS In vitro toxicity was investigated in human skin melanoma Sk-Mel-28 cells, and skin squamous cell carcinoma was induced in CD1 mice by dimethylbenzanthracene (DMBA) and 12-O-tetradecanoyl-phorbol-13-acetate (TPA). RESULTS The calculated IC50 in Sk-Mel-28 cells was 3.41μg/ml of PEG-GNSCs, in presence of laser exposure. Photothermal therapy using laser-stimulated PEG-GNSCs resulted in inhibited volume of skin tumors. Our findings indicated that the inflammatory mediators, nitric oxide and cycloxygenase-2, were inhibited in mice after being treated with low and high doses of PEG-GNSCs, accompanied with laser exposure. However, the tumor necrosis factor -α was markedly elevated, while there was no change in 5-lipoxygenase. The pro-angiogenic factor vascular endothelial growth factor was inhibited, while histone acetylation and apoptosis were induced in tumor-bearing groups, after being treated with laser-stimulated PEG-GNSCs. CONCLUSION The present study indicated the promising photothermal therapeutic effect of laser-stimulated PEG-GNSCs as an effective modality to inhibit the tumor growth, the angiogenesis and partially the inflammation.

Abstract
A series of novel 5-(substituted phenyl)-3-[(substituted phenylamino)methyl]-3H-[1,3,4]oxadiazole-2- thione derivatives were prepared and their in vitro cytotoxicity was evaluated against a panel of three cancer cell lines, namely, hepatocarcinoma HepG2, breast adenocarcinoma MCF-7, and leukemia HL-60 cells, using the widely accepted MTT assay. In general, the synthesized compounds displayed weak to moderate cytotoxic activity against the three tested cell lines. Compound 5a, which has trimethoxy substituents on both phenyl rings, exhibited the highest cytotoxic effect against all cell lines tested with IC50 values of 12.01, 7.52 and 9.7 μM against HepG2, MCF-7 and HL-60 cells, respectively. Mechanistic studies revealed that the test compounds showed a good inhibitory effect on cellular tubulin of hepatocellular carcinoma. Compound 5h was the most potent tubulin inhibitor in HepG2 cells, with 81.1 % inhibition of the original control tubulin. Moreover, the mechanism of tubulin polymerization inhibition was confirmed by immunofluorescence assay, flow cytometry, and docking study.

Abstract
This study validates the utility of Gum Arabic-conjugated gold nanoparticles (GA-AuNPs) and laser to induce photothermal inhibition of hepatocarcinogenesis, via employing a diethylnitrosamine (DEN)-mediated hepatocellular carcinoma model. This work included both of in vitro and in vivo studies; to investigate the GA-AuNPs cytotoxicity and phototoxicity in hepatic cell line; to delineate the GA-AuNPs therapeutic efficiency in DEN-induced preneoplastic lesions (PNLs) in the liver of Balb-C mice. The therapeutic effects of GA-AuNPs on the mediators of apoptosis, inflammation, and tumor initiation, as well as the histopathological changes in preneoplastic liver have been investigated. Our results infer that GA-AuNPs in combination with laser irradiation led to a significant reduction in the cell viability and in histone deacetylase activity in hepatocarcinoma HepG2 cells. In chemically-induced PNLs mice model our results have demonstrated that GA-AuNPs, with or without laser irradiation, induced cancer cell apoptosis through the activation of death receptors DR5 and caspase-3 and inhibited both of the PNLs incidence and the initiation marker (placental glutathione S-transferase; GST-P). The laser-stimulated GA-AuNPs significantly reduced the tumor necrosis factor-α levels. In summary, GA-AuNPs with laser treatment inhibited liver PNLs via the induction of the extrinsic apoptosis pathway and the inhibition of inflammation.

Abstract
AbstractGold nanoparticles (GNPs) are intended to be used in nanomedicine. Due to nanotechnology innovation GNPs of variable sizes and in different shapes including rods, spheres, cubes, etc., can easily be produced. The aim of the present studies was to evaluate the cyto-and genotoxicity inducible by different shaped GNPs on normal human peripheral blood lymphocytes.Four different shapes of GNPs including big rod GNPs (BR-GNPs, 50 nm), small rod GNPs (SR-GNPs, 30 nm), sphere GNPs (S-GNPs, 15 nm) and semi-cube GNPs (SC-GNPs, 15 nm) were studied. Cultured human blood lymphocytes were treated with different concentrations of these GNPs for 24 h in vitro. Cytotoxicity was evaluated based on the mitotic index (MI), while genotoxicity was studied by an interphase-fluorescence in situ hybridization (I-FISH) assay. The following genes were studied in I-FISH:The lowest concentration of BR-GNPs neither had an effect mitotic activity nor enhanced gain or loss of examined gene signals in a significant manner with I-FSH. Other concentrations of BR-GNPs, SR-GNPs, S-GNPs and SC-GNPs with all concentrations inhibited the mitotic activity of the cells and reduced the cell proliferation highly significantly. The different types of GNPs initiated the duplication ofGNPs at high concentration can reduce the cell proliferation and induce DNA damage. Low concentration of rod-shaped GNPs at 50 nm was safe on human lymphocytes. Further research studies are required to optimize the concentration, shape and size of GNPs before using them in nanomedicine.

Abstract
A series of novel 1-(3,4-methoxyphenyl)-5-(3,4,5-trimethoxyphenyl)-1H-1,2,4-triazole-3-carboxylic acid derivatives (4a-n) were synthesized and evaluated for their in vitro cytotoxic activity against the growth of four different human cell lines (hepatocarcinoma HepG2, breast adenocarcinoma MCF-7, colon carcinoma DLD-1, and leukemia HL-60). The anilides of m-anisidine 4e, o-anisidine 4f, and 3,5-difluoroaniline 4l demonstrated best results on MCF-7 cells and mean IC50 values of 7.79, 10.79, and 13.20 µM, respectively. The compounds produced a significant reduction in cellular microtubules at a concentration of 25 µg/mL, for microtubule loss. Molecular modeling studies involving compounds 4d, 4e, 4f, and 4l with the colchicine binding site of α,β-tubulin revealed hydrogen bonding and hydrophobic interactions with several amino acids in the colchicine binding site of β-tubulin.

Abstract
The cancer chemopreventive activity of the polysaccharide extracts (E1-E4) of Sargassum asperifolium, a brown alga in Red Sea shores in Egypt, was investigated. Tumour anti-initiation activity (the modulation of carcinogen metabolism) indicated that E3 and E4 were potent anti-initiators by inhibiting the carcinogen activator cytochrome P450-1A, and enhancing carcinogen detoxification enzymes glutathione-S-transferase. Only E4 significantly enhanced quinone reductase activity. All polysaccharide extracts possessed anti-promotion property by their anti-inflammatory activity. E3 and E4 dramatically induced the growth of spleen macrophages. E2, E3 and E4 significantly inhibited nitric oxide generation from lipopolysaccharide (LPS)-stimulated spleen macrophages, while E1, E3 and E4 led to significant inhibition of LPS-induced tumour necrosis factor-α. The extracts E1, E2 and E4 showed cytotoxicity against HepG2 cells, where E2 and E4 induced cell death due to apoptosis. In conclusion, E3 and E4 are promising cancer chemopreventive extracts, since they had tumour anti-initiating activity via their protective modulation of carcinogen metabolism.

Abstract
Phytochemical studies of an ethanolic extract of the aerial parts of Salvia disermas resulted in the isolation of seven known compounds, rosmarinic (1) and caffeic (2) acids, salvigenin (3), luteolin (4), luteolin 7-O-β-arabinoside (5), luteolin 7-O-β-glucoside (6), and ocotillol II (7). The initiation stage of carcinogenesis is triggered by activation of procarcinogens by phase I enzymes, such as cytochrome P-450 1A, and oxidative stress that leads to DNA damage. The initiation stage is countered by phase II detoxifi cation enzymes such as glutathione S-transferases (GST), quinine reductase (QR), epoxide hydrolase (mEH) besides conjugation with thiols. We aimed to investigate the cancer chemopreventive and tumour anti-initiating activity of the ethanolic extract of the aerial parts of Salvia disermas and its constituents. The S. disermas extract was a promising inhibitor of CYP1A activity, inducer of GST, QR, and mEH activities, enhancer of thiol content, radical scavenger, and inhibitor of DNA damage. On the other hand, 3 was an enhancer of thiol content and QR activity, while 4 was an inhibitor of CYP1A activity, inducer of QR activity, and radical scavenger of ROO•, and 5 was an inducer of GST activity and inhibitor of DNA damage. The present study indicated that the ethanolic extract of S. disermas and 4 are promising anti-initiating and multipotent blocking agents.

Abstract
A new naturally occurring compound based on the dammarane skeleton, i.e. cabralealactone 3-acetate-24-methyl ether, was isolated from the aqueous methanolic extract of Forsythia koreana fruits, along with eight known compounds: cabralealactone 3-acetate, ursolic acid, arctigenin, arctiin, phillyrin, rutin, caffeic acid, and rosmarinic acid. The identifi cation of the isolated compounds was based on their spectral analysis including: HREI-MS, 1D and 2D NMR spectroscopy. The selected compounds and the aqueous methanolic extract were evaluated for their cytotoxic activity against human solid tumour cell lines. Cabralealactone 3-acetate-24-methyl ether and ursolic acid were found to be active against human breast cancer cells (MCF-7). The cytotoxicity was associated with the activation of caspase-8, the induction of the death receptors DR4 and DR5, as well as DNA fragmentation, and was thus due to apoptosis rather than necrosis

Abstract
Phytochemical investigation of Cassia petersiana Bolle leaves afforded four new compounds,
including two chromone derivatives, 7-acetonyl-5-hydroxy-2-methylchromone (petersinone
1, 1) and 7-(propan-2ʹ-ol-1ʹ-yl)-5-hydroxy-2-methylchromone (petersinone 2, 2),
two benzoic acid derivatives, 5-methyl-3-(propan-2ʹ-on-1ʹ-yl) benzoic acid (petersinone 3, 3)
and 5-(methoxymethyl)-3-(propan-2ʹ-ol-1ʹ-yl) benzoic acid (petersinone 4, 4), and glyceryl-
1-tetracosanoate (6), in addition to the known compound sistosterol-3-β-ᴅ-glycoside (5). The
structures of these compounds were determined by comprehensive NMR studies, including
DEPT, COSY, HMQC, HMBC, MS and IR.
Compounds 1, 2, 5 and 6 were tested for antioxidant, anti-cancer and immunostimulatory
properties. The biological investigations indicated that compound 6, among others, possessed
the highest anti-cancer activity against hepatocellular carcinoma, immunoproliferative activity
via induction of T-lymphocytes and macrophage proliferation, anti-inflammatory activity
as indicated by NO inhibition, and antioxidant activity against DPPH radicals. Moreover,
compound 5 was the most effective cytotoxic compound against breast carcinoma and stimulated
a consistent immunoproliferative effect on lymphocytes and macrophages combined
with strong NO inhibitory activity, while compound 1 was promising as immunoproliferative
agent and may act as anti-inflammatory agent as a consequence of its NO inhibitory activity.

Abstract
BACKGROUND Indocyanine green (ICG) is a promising water-soluble photosensitizer for photodynamic therapy (PDT) of tumors. It was reported to have promising phototoxic effect on different cell lines. This study aimed to evaluate the efficacy of ICG as an efficient PS agent for skin cancer induced in mice. METHODS Skin squamous cell carcinoma was induced in female CD-1 mice by 7,12-dimethylbenzanthracene and 12-O-tetradecanoyl-phorbol-13-acetate followed by an ICG/PDT treatment. The laser irradiation for PDT was adjusted to cover the whole body of the mice to make sure that the treatment protocol will be delivered to multiple tumors. RESULTS The treatment of skin cancer by ICG/PDT using intravenously injected ICG initiated tumor cell death and significantly decreased cell proliferation as indicated by the reduction in proliferating cell nuclear antigen positivity. A significant reduction in the inflammatory mediators; tumor necrosis factor-α, nitric oxide and 5-lipoxygenase was reported, however the level of cyclooxygenase-2 (COX-2) was significantly elevated after ICG/PDT treatment. CONCLUSION The proposed ICG/PDT treatment modality showed a significant anti-tumor and anti-inflammatory activity against skin cancer accompanied with COX-2 elevation.

Abstract
BACKGROUND 5-Aminolevulinic acid (ALA) is a natural heme precursor metabolized into protoporphyrin IX (PpIX). PpIX preferentially accumulates in tumor cells resulting in the formation of singlet oxygen upon exposure to visible light. Doxil(®), an active agent against breast and ovarian cancer, is a nano-formulation of doxorubicin. This study aimed to investigate in vitro synergistic cytotoxic effect of low doses of combined chemotherapy and ALA/PDT to human breast adenocarcinoma cells (MCF-7) compared to high doses of each individual therapy. METHODS MCF-7 cells were pretreated with Doxil(®) (48 h) followed by ALA/PDT (4h). The cell viability was evaluated by trypan blue assay and PpIX production was measured spectrofluorometrically. Alkaline phosphatase was determined as a marker for cellular differentiation. Apoptosis and necrosis were evaluated by fluorescence stains. The apoptosis cell death pathways were investigated: detection of mitochondrial membrane potential (ΔΨm) and percent of DNA fragmentation, malondialdehyde, histone deacetylase (HDAC) activity, caspase-3 and death receptors (DR4 and DR5). Vascular endothelial growth factor (VEGF) was determined by ELISA, as an angiogenic mediator. RESULTS There was a higher reduction in cell viability in Doxil(®)+ALA/PDT-treated cells compared with their individual effect. The combined therapy showed enhanced apoptosis with a significant increase in the loss of ΔΨm, DNA fragmentation %, caspase-3, DR4, DR5 and lipid peroxides and inhibited HDAC. Pretreatment with Doxil(®) resulted in a twofold increase in the intracellular PpIX, by increasing the PDT killing of MCF-7 cells. CONCLUSION The combined therapy using 50% of IC50 of ALA/PDT and Doxil(®) possessed a synergistic apoptotic effect on MCF-7 cells compared to 100% of IC50 of each therapy through enhancing both intrinsic and extrinsic apoptotic pathways, thus may minimize side effects of Doxil(®) and ALA.

Abstract
BACKGROUND Indocyanine green (ICG) is a promising photosensitive agent for photodynamic therapy (PDT) of tumors. Encapsulating ICG dye in polymeric nanoparticles based on PEBBLE technology forming (ICG-PEBBLE) could improve the aqueous stability of the entrapped ICG molecules. The study objective is to investigate the PDT effect of free ICG-PEBBLE and its Anti-EGFR conjugate. METHODS Skin squamous cell carcinoma was induced in CD1 mice by dimethylbenzanthracene (DMBA) and 12-O-tetradecanoyl-phorbol-13-acetate (TPA) followed by a PDT protocol for four weeks. RESULTS PDT using ICG-PEBBLE or ICG-PEBBLE-Anti-EGFR decreased skin tumor sizes. Our findings revealed that the inflammatory mediators tumor necrosis factor (TNF-α), nitric oxide (NO), cycloxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX), the angiogenic mediator vascular endothelial growth factor (VEGF), and proliferating cell nuclear antigen (PCNA) were decreased, while apoptosis, caspase-3 and histone acetylation were induced in tumor bearing groups after PDT using both of ICG-PEBBLE or ICG-PEBBLE-Anti-EGFR. CONCLUSION The present study indicated the effectiveness of PDT using ICG-PEBBLE or ICG-PEBBLE-Anti-EGFR as an inhibitor modality for tumor size, apoptosis, angiogenesis and tumor inflammation. The conjugating of ICG-PEBBLE to anti-EGFR was found to be more effective in inhibiting VEGF and in increasing caspase-3 compared to free ICG-PEBBLE, but there were no other preferential PDT efficacy.

Abstract
A series of twenty five 2-methylsulfanyl-[1,2,4]triazolo[1,5-a]quinazoline derivatives 1-25 was previously synthesized. We have now investigated their cytotoxic effects against hepatocellular Hep-G2 and colon HCT-116 carcinoma cells and effect on the macrophage growth, in addition to their influence of the inflammatory mediators [nitric oxide (NO), tumor necrosis factor-α (TNF-α), prostaglandin E-2 (PGE-2) and in bacterial lipopolysachharide (LPS)-stimulated macrophages]. The findings revealed that compounds 13 and 17 showed the highest cytotoxicity and that 3, 6-8 and 25 are promising multi-potent anti-inflammatory agents.

Abstract
A new naturally occurring compound based on the dammarane skeleton, i.e. cabralealactone 3-acetate-24-methyl ether, was isolated from the aqueous methanolic extract of Forsythia koreana fruits, along with eight known compounds: cabralealactone 3-acetate, ursolic acid, arctigenin, arctiin, phillyrin, rutin, caffeic acid, and rosmarinic acid. The identification of the isolated compounds was based on their spectral analysis including: HREI-MS, 1D and 2D NMR spectroscopy. The selected compounds and the aqueous methanolic extract were evaluated for their cytotoxic activity against human solid tumour cell lines. Cabralealactone 3-acetate-24-methyl ether and ursolic acid were found to be active against human breast cancer cells (MCF-7). The cytotoxicity was associated with the activation of caspase-8, the induction of the death receptors DR4 and DR5, as well as DNA fragmentation, and was thus due to apoptosis rather than necrosis.

Abstract
The alga Sargassum dentifolium (Turner) C. Agardh, belongs to Sargassaceae, is a brown seaweed in red sea shores in Egypt. This work aimed to extract different water-soluble polysaccharide extracts (E1, E2, and E3) from S. dentifolium and to investigate their protective effect against cyclophosphamide (CP)-induced genotoxicity. Mice bone marrow cells (BMCs) were collected and analyzed for the chromosomal aberration, micronucleated BMCs (MN-BMCs), the mitotic index, DNA fragmentation by comet assay, and histone deacetylases (HDACs), and radical scavenging capacity of extracts was evaluated by the oxygen radical absorbance capacity assay. The results indicated that E2 and E3 significantly inhibited CP-induced multiple chromosomal aberrations, where E1 and E3 significantly suppressed the number of CP-induced formation of tetraploidy. The extracts prohibited the cytotoxic effect of CP and recovered the mitotic activity, whereas E1 possessed the highest recovery and mitosis. In absence of MN, CP induced formation of bi- and poly-nucleated BMCs. E1 prohibited CP-induced formation of bi-nucleated BMCs, while E2 and E3 prohibited CP-induced formation of poly-nucleated BMCs. CP-induced MN-BMCs were accompanied with mono-, bi- and poly-nucleated cells. E1 and E3 remarkably suppressed mono-nucleated MN-BMCs, while E2 inhibited bi-nucleated MN-BMCs. All the extracts significantly inhibited the CP-induced formation of poly-nucleated MN-BMCs. CP-induced DNA fragmentation was inhibited by all extracts, where E1 was the strongest inhibitor as concluded from the comet tail moment. All the extracts were strong OH scavengers, while only E3 was ROO scavenger. The results revealed a drastic decline in HDACs activity by E1 and E3. In conclusion, S. dentifolium polysaccharide extracts E1 and E3 possessed a potential anti-genotoxic and a promising anti-mutagenic activity.

Abstract
BACKGROUND Photodynamic therapy (PDT) is used for the treatment of many types of predominantly epithelial cancers. Photosensitizer is taken up by fast growing tumor cells more actively than by other body cells and is activated by light, generating reactive oxygen species that cause cell death by necrosis or apoptosis. This study aimed to evaluate the efficacy of PDT with indocyanine green (ICG) through the investigation of TP53, HER-2 and TOP2A genes signals as breast cancer gene markers by interphase fluorescence in situ hybridization (nuc-FISH). METHODS The photosynthetizer ICG (200 μM) was applied to breast cancer cell line MCF-7 cells (adenocarcinoma) in combination with laser irradiation (807 nm) exposure for 20 min and then incubated for 12, 24 and 48 h. Cell viability was evaluated using trypan blue. The signals for nuc-FISH was investigated and counted for probes specific for the genes TP53 (17p13), HER-2 (17q11.2-q12), and TOP2A (17q21-q22), and BAC-probes RP11-746M1 in 17p11.2 and RP11-403E9 in 17q11.2. RESULTS The cell viability of MCF-7 did not reduced significantly when the cells were treated with ICG (200 μM) or exposed to laser irradiation for 20 min followed by incubation for 24 h. ICG/PDT treatment with laser irradiation exposure for 20 min reduced the cell viability after incubating cells for 12, 24 and 48 h highly significantly in a time dependent manner. For nuc-FISH analysis, TP53, HER-2, TOP2A, RP11-746M1 and RP11-403E9 signals did not reduce or increase in a significant manner when the cells were treated with ICG or exposed to laser irradiation for 20 min then incubated for 24h. PDT enhanced amplification of TP53 signals from nuc ish 17p13(TP53×2) to nuc ish 17p13(TP53×3) or nuc ish 17p13(TP53×4). However, the signals of HER-2 gene, TOP2A gene and BAC probes were reduced highly significantly when MCF-7 cells were treated with PDT with all time intervals. CONCLUSION ICG/PDT and laser induced cytotoxic effect in MCF-7 cells. Also, PDT enhanced TP53 gene amplification, and reduced HER-2, TOP2A, and BAC probes RP11-746M1 and RP11-403E9 signals. Therefore ICG/PDT can be used for breast cancer treatment. It has the potential to induce apoptotic effect and reduce HER-2 and TOP2A genes propagation. Further in vivo studies are needed to evaluate ICG/PDT as a promising therapeutic approach for breast cancer.
