Abstract
LncRNAs, pseudogenes, and miRNAs participate a fundamental function in tumorigenesis, metabolism, and invasion of cancer cells, although their regulation of tumor glycolysis in prostate adenocarcinoma (PRAD) is thoroughly not well studied. In this study, we applied transcriptomic, proteomic, and medical information to identify glycolysis-related key genes and modules associated with PRAD. Then, the glycolysis-related lncRNA/lncRNAs/pseudogenes-miRNA-mRNA network was constructed. Analysis of DNA methylation status and expression data determined a DNA methylation-dysregulated three-DE-mRNAs signature for predicting diagnosis, ANGPTL4, GNE, and HSPA in PRAD patients and healthy control. Several lncRNAs/pseudogenes, significantly correlated with the overall survival PVT1, CA5BP1, MIRLET7BHG, SNHG12, and ZNF37BP and disease-free survival status, MALAT1, GUSBP11, MIRLET7BHG, and SNHG1, of patients with PRAD were determined. The methylation profile of DE-lncRNA/pseudogenes was significantly proper for predicting PRAD prognostic model. The transcription level of 6 DE-mRNA ANGPTL4, QSOX1, BIK, CLDN3, DDIT4, and TFF3 was correlated with cancer-related fibroblast infiltration in PRAD. The mutated form of 7 mRNAs, COL5A1, IDH1, HK2, DDIT4, GNE, and QSOX1, was associated with PRAD. In addition to the glycolysis pathway, DE-RNAs play regulatory roles on several pathways, including DNA damage, RTK, cell cycle, RAS/MAPK, TSC/mTOR and PI3K/AKT, AR hormone, and EMT. Overall, our study improves our knowledge of the relation between lncRNAs/pseudogenes and miRNA related to glycolysis and PRAD pathogenesis.

Abstract
BACKGROUND Enzybiotics are promising alternatives to conventional antibiotics for drug-resistant infections. Exolysins, as a class of enzybiotics, show antibacterial effects against methicillin-resistant Staphylococcus aureus (MRSA). This study evaluated a novel exolysin containing an SH3b domain for its antibacterial activity against MRSA. METHODS This study designed a chimeric exolysin by fusing the Cell-binding domain (SH3b) from Lysostaphin with the lytic domain (LYZ2) from the gp61 enzyme. Subsequently, LYZ2-SH3b was cloned and expressed in Escherichia coli (E. coli). Finally, the antibacterial effects of LYZ2-SH3b compared with LYZ2 and vancomycin against reference and clinical isolates of MRSA were measured using the disc diffusion method, the minimal inhibitory concentration (MIC), and the minimal bactericidal concentration (MBC) assays. RESULTS Analysis of bioinformatics showed that LYZ2-SH3b was stable, soluble, and non-allergenic. Protein purification was performed with a 0.8 mg/ml yield for LYZ2-SH3b. The plate lysis assay results indicated that, at the same concentrations, LYZ2-SH3b has a more inhibitory effect than LYZ2. The MICs of LYZ2 were 4 µg/mL (ATCC 43,300) and 8 µg/mL (clinical isolate ST239), whereas, for LYZ2-SH3b, they were 2 µg/mL (ATCC 43,300) and 4 µg/mL (clinical isolate ST239). This suggests a higher efficiency of LYZ2-SH3b compared to LYZ2. Furthermore, the MBCs of LYZ2 were 4 µg/mL (ATCC 43,300) and 8 µg/mL (clinical isolate ST239), whereas, for LYZ2-SH3b, they were 2 µg/mL (ATCC 43,300) and 4 µg/mL (clinical isolate ST239), thus confirming the superior lytic activity of LYZ2-SH3b over LYZ2. CONCLUSIONS The study suggests that phage endolysins, such as LYZ2-SH3b, may represent a promising new approach to treating MRSA infections, particularly in cases where antibiotic resistance is a concern. But further studies are needed.

Abstract
BACKGROUND Natural treatment of cancer has received a lot of attention recently due to its advantages including low cost, and fewer side effects. In this study, we aimed to investigate the antimetastatic properties of Cyrtopodion scabrum, a common home gecko, through Epithelial-Mesenchymal Transition (EMT) process. METHODS Human colon cancer HCT116 cell line was selected and allocated into the following experimental groups: untreated control, vehicle control (DMSO), Retinoic acid (RA), and two treatment groups including aqueous C.scabrum Whole Extract (CWE) and C.scabrum Cell Extract (CCE) groups. The effects of the two different extracts on the viability, migration, and morphology of HCT116 cells were investigated using MTT, colony formation, and wound healing assay as well as microscopic evaluation. We also investigated the gene expression of E-cad, N-cad, and Snail genes using Real-Time PCR analysis. RESULTS Our findings revealed that CWE and CCE were toxic to the HCT116 cell line with IC50 values of 590 and 680 µg/mL, respectively. Colony formation and migration ability of cancer cells were also inhibited by the two extracts, and the morphology of the cells were determined as epithelial phenotype. Moreover, the expression of N-cad and Snail were remarkably decreased in CWE and CCE, and RA groups, while E-cad didn't change significantly as compared to the control. CONCLUSION The results suggest that C. scabrum extract (CsE) may induce its anti-cancer activity through the inhibition of cancer cell growth and the EMT process. CCE, as a valuable natural source, could be also suggested, to be used as an alternative/complementary medicine for the treatment of cancer, in clinical trials.

Abstract
The main strategy of cancer cells for survival is uncontrolled cell division and escape from apoptosis. The use of anticancer agents inducing the production of reactive oxygen species (ROS) and controlling cell division might be a therapeutic approach to eradicate cancer cells. Herein, we examined the therapeutic effects of Auraptene on CT26 cells as well as on a mouse model of colorectal cancer (CRC). The spheroid assay was also conducted to analyze the anti-proliferative activity of Auraptene. We also assessed the in vitro analysis of ROS generation. The impact of Auraptene on oxidant/antioxidant markers, as well as the mRNA expression of Bax, Bcl-2, Nrf2, Cyclin D1, and Survivin genes, was evaluated by qPCR in tumor samples. As a result, Auraptene significantly reduced the size of CT26 spheroids at a dose of 200 µM. After 12 h, ROS levels were significantly elevated in CT26 cells. The administration of Auraptene induced apoptosis and the cell cycle arrest by modulating Bax, Bcl-2, Nrf2, Cyclin D1, and Survivin mRNA levels. Furthermore, our results demonstrated that Auraptene suppressed CAT, GSH (reduced Glutathione), and FRAP while increasing MDA in tissue homogenates which in turn could raise oxidative stress and stimulate apoptosis. Therefore, Auraptene may act as a powerful adjuvant therapy in CRC since it triggers apoptosis and cell cycle.

Abstract
Background:
Recent investigations have demonstrated that metformin treatment can decrease tumor incidence and growth using cell cycle arrest and induction of apoptosis pathway. However, it is not clear how metformin affects the factors involved in the apoptotic process.
Objective:
The present study aimed to determine the effect of metformin on Bak, Bad, and Bim pro-apoptotic proteins using docking and dynamics simulation studies.
Method:
The 3D structure of molecules was retrieved from PubChem and RCSB servers. Simulation and docking studies were conducted by Gromacs and AutoDock software. Next, molecular dynamics analysis was performed using Gromacs software. Moreover, LigPlot+V.4.5.3 software was applied for the determination of the hydrogen and hydrophobic interactions at the binding sites.
Result:
Our findings demonstrated that metformin has the highest affinity for binding the Bak protein. This binding occurred using four amino acid residues within the binding site of Bak with the minimum binding energy (-5.70 kcal/mol). The molecular docking of metformin to these pro-apoptotic factors significantly decreased the total energy and increased the coil secondary structure of Bak protein.
Conclusion:
According to our findings, metformin can alter the molecular dynamics property of these proteins which results in increased activity of these pro-apoptotic proteins and induction of apoptosis.

Abstract
Cell therapy and tissue engineering as promising candidates for the liver transplantation dilemma are of special interest. Induced pluripotent stem cells (iPSCs) are one of the best sources in this field, but their differentiation methods to hepatocytes have remained challenging. We transduced human iPSCs (hiPSCs) with miR-122 and off-let-7f (hiPSCsmiR-122 + off-let-7f ) to evaluate how they can differentiate hiPSCs to hepatocyte-like cells (HLCs) without any extrinsic growth factor. Additionally, we studied the effect of Poly ɛ-caprolactone-gelatin-hyaluronic acid (PCL-Gel-HA) nanofibrous scaffold as an extracellular matrix (ECM) simulator on differentiation improvement. Definitive endoderm markers (FOXA2 and SOX17), as well as hepatic markers (AFP, Albumin, CK18, HNF4α) expression, were significantly higher in hiPSCsmiR-122 + off-let-7f derived HLCs (hiPSCs-HLCs) compared to the control group (miR-scramble transduced hiPSCs: hiPSCsscramble ). hiPSCs-HLCs indicated hepatocyte morphological characteristics and positive immunostaining for AFP, Albumin and HNF4α. Albumin and urea secretion were significantly higher in hiPSCs-HLCs than hiPSCsscramble . Comparing these markers in the PCL-Gel-HA group with the tissue culture plate (TCP) group revealed that PCL-Gel-HA could improve differentiation towards HLCs significantly. Regarding our results, these microRNAs can be used to differentiate hiPSCs to the functional hepatocytes for disease modelling, drug screening and cell-based therapy in future studies.

Abstract
INTRODUCTION Here, we aimed to investigate whether the beneficial effects of metformin on lipid accumulation is mediated through regulation of miR-33b. METHODS The expression of the genes and miRNAs and protein levels were evaluated using real-time PCR and western blot, respectively. To investigate the potential role of miR-33b in lipid accumulation, the mimic of the miR-33b was transfected into HepG2 cells. RESULTS We found that metformin reduces high glucose-induced lipid accumulation in HepG2 cells through inhibiting of SREBP1c and FAS and increasing the expression of CPT1 and CROT. Overexpression of miR-33b significantly prevented the decreasing effect of metformin on lipid content and intra and extra triglyceride levels. Importantly, miR-33b mimic inhibited the increasing effects of metformin on the expression of CPT1 and CROT. CONCLUSION These findings suggest that metformin attenuates high glucose-induced lipid accumulation in HepG2 cell by downregulating the expression of miR-33b.

Abstract
Background Serological diagnosis of Strongyloides stercoralis (S. stercoralis) is fre-quently challenging because of cross-reactivity with other parasitic nematodes. Therefore, it is necessary to introduce novel serological tests with high performance to properly diagnose this neglected parasitic infection. The purpose of the current study was to design a multi-epitope construct for the diagnosis of S. stercoralis. Methods For the purpose of this study, first, highly antigenic segments and potential immunodominant epitopes of S. stercoralis were identified from two antigenic proteins, and then all of the selected parts were linked by an appropriate linker. Next, the physicochemical features of the designed construct were analyzed. Then, tertiary structures of the construct were built and evaluated to find out the best one. Lastly, the amino acid sequence was reverse-translated and optimized for over-expression in Escherchia coli (E. coli). Results The bioinformatic evaluation indicated that the designed protein construct could be hydrophilic, thermostable, and acidic and the estimated half-life was more than 10 hr in E. coli. Conclusion According to the results of the study, the designed construct could be used as an efficient antigen in the ELISA system for serological diagnosis of human strong-yloidiasis.

Abstract
The epithelial-to-mesenchymal transition (EMT) is a unique process resulting in enhanced cell motility, invasiveness, and metastasis in cancer. The EMT is regulated by several transcription factors, including Snail and Slug, which exert crucial roles during cancer progression. We have studied the effects of Docetaxel as the first-line chemotherapy agent for prostate cancer, and Telmisartan as an anti-hypertensive drug on the expression level of Snail and Slug. In addition, the effects of Docetaxel, Telmisartan and their combination on cancer cell proliferation were investigated. The PC3, DU145, MDA-MB468, and HEK cell lines were used for this study. Quantitative RT-PCR analysis and MTT assay were used to study the expression of Snail and Slug level and cell proliferative assay, respectively. We found that a combination of Docetaxel + Telmisartan effectively inhibits the cell proliferation in cancerous cells in comparison with each drug alone (P<0.05). Furthermore, in these cell lines, Docetaxel, Telmisartan and their combination significantly diminished the expression level of Snail and Slug genes compared to control cells (P<0.001), however, in the HEK cell line, this effect was seen only in the combination group. Our data imply that Telmisartan and its combination with Docetaxel exert strong inhibitory effects on the expression level of Snail and Slug genes. Also, these drugs and their combination could inhibit cancer cell proliferation. In conclusion, the combination of Telmisartan and Docetaxel has the potential to suppress the metastasis of prostate and breast cancer cells.

Abstract
BACKGROUND Metastasis is a major cause of death in Colorectal cancer (CRC) patients, and the Epithelial-mesenchymal transition (EMT) has been known to be a crucial event in cancer metastasis. Downregulated expression of AT-rich interaction domain-containing protein 1A (ARID1A), a bona fide tumor suppressor gene, plays an important role in promoting EMT and CRC metastasis, but the underlying molecular mechanisms remain poorly understood. Here, we evaluated the impact of ARID1A knockdown and overexpression on the expression of EMT‑related genes, E-cadherin and β-catenin, in human CRC cells. METHODS AND RESULTS The expression levels of ARID1A, E-cadherin and β-catenin in CRC cell lines were detected via real-time quantitative PCR (qPCR) and western blot. ARID1A overexpression and shRNA-mediated knockdown were performed to indicate the effect of ARID1A expression on E-cadherin and β-catenin expression in CRC cell lines. The effect of ARID1A knockdown on the migration ability of HCT116 cells was assessed using wound-healing assay. We found that the mRNA and protein expression of adhesive protein E-cadherin was remarkably downregulated in response to shRNA-mediated ARID1A knockdown in HCT116 and HT29 cells. Conversely, overexpression of ARID1A in SW48 cells significantly increased E-cadherin expression. In addition, ARID1A silencing promoted the migration of HCT116 cells. ARID1A knockdown and overexpression did not alter the level of β-catenin expression. CONCLUSIONS Our study demonstrates that E-cadherin levels were closely correlated with ARID1A expression. Thus, ARID1A downregulation may promote CRC metastasis through decreasing EMT‑related protein E-cadherin and promoting epithelial cell movement. ARID1A could represent a promising candidate therapeutic target for CRC.

Abstract
OBJECTIVE Diabetic women have different reproductive problems. In pregnant diabetic women, high rates of perinatal mortality, spontaneous abortion and congenital anomalies are observed. We hypothesized that quercetin, as an antidiabetic and phytoestrogen, might have protective effects on the embryo implantation in pregnant diabetic mice. We investigated the ameliorative effects of quercetin on the levels of serum estrogen and progesterone, rate of blastocyst implantation, and uterine receptivity markers in diabetic mice. MATERIALS AND METHODS Diabetic and healthy female mice were treated with quercetin (30 mg/kg/day) four weeks before pregnancy. Plasma sex-steroid levels were determined on day 4 of pregnancy. Also, uteri were harvested for investigation of protein and mRNA expression changes. In another set of our study, implantation rate was determined on day 5 of pregnancy. RESULTS Our results indicated that quercetin was significantly reduced blood glucose levels in diabetic mice. The number of implantation sites as well as serum estradiol level was reduced in diabetic mice, and then treatment with quercetin significantly increased both. On the other hand, insulin like growth factor1, integrin αvβ3, and cyclooxygenase2 mRNA expression in the uterus of diabetic mice were significantly reduced, and quercetin treatment augmented the expression level of these genes. Besides, the level of inactive β-catenin protein level in the uterus of diabetic mice was higher than normal group; treatment with quercetin reduced the level of inactive β-catenin protein as compared to diabetic mice. CONCLUSION We conclude that administration of quercetin before pregnancy can probably alleviate reproductive problems in diabetic women likely via its estrogenic and antihyperglycemic effects.

Abstract
OBJECTIVES The aim of this study is to investigate the effect of two abundant dietary supplements, quercetin and vitamin C on some factors involved in metastasis and proliferation of prostate cancer, which are resistant to conventional chemotherapies in late stages. BACKGROUND Bone and brain are two common sites of metastases in prostate cancer, nevertheless the factors involved in their metastatic pathways are not well understood. METHODS The effect of quercetin (75µM) and vitamin C (100 µM) on CXCR4, CXCR7 chemokine receptors, α4, α5 and β1 integrins, ki-67 proliferation marker and Vascular endothelial growth factor, VEGF was evaluated using Quantitative Reverse Transcription PCR (RT-qPCR). RESULTS The effect of quercetin and vitamin C alone was different on PC3 and DU145 prostate cancer cell lines, but sequential combination reduced significantly the expression of CXCR and CXCR7 chemokine receptors, α4, α5 and β1 integrin subunits, VEGF and Ki-67 proliferation markers in PC3 and DU145 cell lines. CONCLUSION Our results indicated the beneficial effect of quercetin and vitamin C on prostate cancer cells with different metastatic sites and their differential response to the treatment which in turn may lead us to reach suitable therapeutic outcomes to combat cancer (Fig. 3, Ref. 36).

Abstract
Spinal cord injury (SCI) causes histological alterations which in turn affects functional activity. Studies have demonstrated that dental pulp-derived stem cells conditioned medium has beneficial effects on the nervous system. Besides, collagen hydrogel acts as a drug releasing system in SCI investigations. This research aimed to evaluate effects of dental pulp-derived stem cells conditioned medium loaded in collagen hydrogel in SCI. After culturing of Stem cells from human exfoliated deciduous teeth (SHEDs), SHED-conditioned medium (SHED-CM) was harvested and concentrated. Collagen hydrogel containing SHED-CM was prepared. The rats were divided into five groups receiving laminectomy, compressive SCI with or without intraspinal injection of biomaterials (SHED-CM and collagen hydrogel with or without SHED-CM). After 6 weeks, histological parameters were estimated using stereological methods. The total volume of preserved white matter and gray matter (p < 0.05) as well as the total number of neurons and oligodendrocytes in the rats received SHED-CM loaded in collagen hydrogel were significantly higher, and also lesion volume and lesion length were significantly lower (p < 0.05) compared to those of the other injured groups. In conclusion, intraspinal administration of SHED-CM loaded in collagen hydrogel leads to neuroprotection, proposing a cell-free therapeutic approach in SCI.

Abstract
Prostate cancer (PC) is known as the most frequent cancer among men in the world. Androgen Deprivation Therapy (ADT) is one of the initial treatment approaches in the PC therapy and various drugs can be used in routine Hormonal therapy for PC therapy. Nevertheless, PC cells can survive and continue their growth via different mechanisms which lead to their resistance to common treatments i.e., Enzalutamide. olutamide (ODM-201) is a second-generation androgen receptor (AR) inhibitor with a new chemical structure and has a high affinity to the AR. Darolutamide does not cross the blood-brain barrier and for this reason, reduces the possibility of seizures. Darolutamide can also inhibit the transcriptional activity of several AR mutant variants (F877L, F877L/T878A, and H875Y/T878A), which are Enzalutamide resistant. In this review, we reviewed the results of different studies: in vitro, animal model and phase 1, 2 and 3 clinical trials (ARADES, ARAFOR and ARAMIS). We shall discuss worldwide phase 2 and 3 clinical trials (ARASENS and ODENZA) that are in progress, in order to demonstrate the advantages of Darolutamide consumption in different groups of patients. Darolutamide has shown high potential in inhibiting the growth of MR49F (Enzalutamide resistant PC cells) and VCaP (Castration-resistant PC cells) cell lines and transcriptional activities of AR. Fewer doses of Darolutamide are needed compared to Enzalutamide. The drug had significant anti-tumor activity and no effect on serum testosterone levels in animal models. Darolutamide demonstrates its safety and efficacy in different studies and was well tolerated nearly in all of the patients.

Abstract
Osteoporosis is the most prevalent metabolic bone disease and one of the most important postmenopausal consequences. The aim of this study was to investigate the effects of quercetin (Q) and vitamin E (vitE) on ovariectomy-induced osteoporosis. Animals were ovariectomized and treated with Q (15 mg/kg/day), vitE (60 mg/kg/day), estradiol (10 µg/kg/day), and Q (7.5 mg/kg/day) + vitE (30 mg/kg/day) for 10 weeks by gavage, and osteoporosis markers and messenger RNA (mRNA) expression of autophagy and apoptosis-related genes were analyzed in serum and tibia of rats. Data indicated that ovariectomy resulted in development of osteoporosis as demonstrated by reduction in serum calcium, bone weight, bone volume, trabeculae volume, and the total number of osteocytes and osteoblasts, and increase in the total number of osteoclasts and serum osteocalcin. Total mRNA expressions of LC3, beclin1, and caspase 3 were also increased and bcl2 expression was decreased in the tibia. By reversing these changes, treatment with Q and vitE markedly improved osteoporosis. In conclusion, Q, and to a lesser extent, vitE, prevented osteoporosis by regulating the total number of bone cells, maybe through regulating autophagy and apoptosis.

Abstract
OBJECTIVE The current study assesses the effects of platelet-rich plasma-fibrin glue (PRP-FG) dressing along with oral vitamin E and C on wound healing and biochemical markers in patients with non-healing diabetic foot ulcers (non-healing DFU). METHODS This randomized controlled trial was performed on 25 patients with non-healing DFU. Patients were treated with PRP-FG dressing plus oral vitamin E and C (intervention group) or PRP-FG dressing plus placebo (control group) for 8 weeks. RESULTS Eight weeks after treatment, six wounds in the intervention group and two wounds in the control group were completely closed, and also wound size significantly reduced in both intervention and control groups (p < 0.05). This reduction in wound size was significantly greater in the intervention group compared to the control group (p = 0.019). Also, a significant decrease in prooxidant-antioxidant balance (PAB) , ESR, and hs-CRP was observed in the intervention group compared to the control group (p < 0.05). CONCLUSION Our results showed that PRP-FG dressing along with oral vitamin E and C could be used to increase wound healing in patients with non-healing DFU by enhancing the wound healing process and reducing oxidative stress. TRIAL REGISTRATION This trial is registered at ClinicalTrials.gov (CT.gov identifier: NCT04315909).

Abstract
Background Cystic echinococcosis (CE) is one of the most important helminthic parasitic diseases in Iran. The current study aimed to assess the seroprevalence of CE in North Khorasan Province, Northeast of Iran in 2018. Methods The study was carried out in seven cities of North Khorasan Province. Venous blood samples were collected from 932 individuals referring to health centers of those seven cities. A questionnaire was used to obtain the data regarding the subject's gender, age, residence and risk factors linked to the hydatid cyst. Sera samples were evaluated for anti-hydatid cyst antibodies in an ELISA system, using a recombinant B8/1 antigen of E. granulosus. Results Of the 932 recruited subjects, 496 (53.2%) were male and 436 (46.8%) were female. The range of participants' age was between 11 to 83 yr old and the mean age of the subjects was 35.4 (±12.7) years. Anti-hydatid cyst antibodies were detected in the sera of 37 out of 932 subjects, corresponding to a seroprevalence rate of 3.96%. From these, 20 (54.05%) were male and 17 (45.95%) were female. There were no associations between seropositivity to hydatid cyst and age, the gender of the participants, residential areas and having contact with dogs (P>0.05). Conclusion CE is relatively prevalent throughout the North Khorasan Province in the Northeast of Iran. Rate of CE infection in this Province is somewhat similar to the rate of infection in other parts of the country.

Abstract
Endometriosis, as the leading cause of infertility, is attributed to oxidative stress, inflammation, and autophagy dysregulation. This study was conducted to evaluate the effect of quercetin and metformin, alone or in combination, on the ectopic and eutopic endometrial tissues in a rat model of endometriosis. We divided 60 female rats into 6 groups, including SH, Endo, Endo + Oil, Endo + Q, Endo + M, and Endo + Q + M. The last five groups underwent a surgery, so that we could induce endometriosis, and after 4 weeks, daily treatment began, lasting for a month. Subsequently, the size and histoarchitecture of the endometrial implants, serum levels of 17β-estradiol, progesterone and tumor necrosis factor (TNF)-α, and markers of oxidative stress and autophagy were assessed utilizing ELISA and gene expression analysis. Our results shed light to the fact that serum TNF-α and 17β-estradiol levels significantly increased in endometriosis rats. Moreover, NADPH: quinone oxidoreductase (NQO1) enzyme activity and gene expression levels of nuclear factor erythroid 2-related factor 2 (Nrf2) and autophagy markers significantly decreased; meanwhile, mammalian target of rapamycin (mTOR) gene expression increased in the ectopic endometrial tissues, as compared with eutopic ones. Surprisingly, our results demonstrated that the treatment in which we applied the combination of quercetin and metformin significantly reversed these changes and had a pronounced effect on the endometrial implant size and gene expression levels of mTOR and autophagy markers in ectopic endometrium. The findings of the present study suggest that quercetin, metformin, and their combination were of potential therapeutic effects on the rat model of endometriosis.

Abstract
OBJECTIVE Considering the role of oxidative stress in the development and progression of endometriosis, the ameliorative effect of caffeic acid treatment on ectopic, eutopic endometrial cells enzyme activities was investigated. We also determined the underlying cellular mechanisms. MATERIALS AND METHODS Ectopic endometrial specimens were collected from women with confirmed cases of endometriosis (n = 10) and eutopic specimens from (n = 10) controls. Following endometrial cell isolation and culture, eutopic and ectopic endometrial cells were treated with caffeic acid. Then, reactive oxygen species (ROS) level, NAD(P)H quinone oxidoreductase 1 (NQO1), and Heme oxygenase 1 (HO-1) enzyme activities, nuclear factor erythroid 2-related factor 2 (Nrf-2) gene expression were measured. RESULTS In ectopic endometrial cells, caffeic acid caused a significant elevation in Nrf-2 gene expression level, NQO1, and HO-1 enzyme activities. In addition, reduced ROS level was observed in caffeic acid-treated ectopic endometrial cells in comparison with the control. On the contrary, we did not observe any significant changes in caffeic acid-treated eutopic endometrial ones. CONCLUSION Caffeic acid can protect the endometrial cells against oxidative stress and might be able to prevent the progression of endometriosis and its related complications, such as pain and infertility.

Abstract
The mammalian target of rapamycin (mTOR) is an evolutionarily conserved serine/threonine-protein kinase that senses and combines various environmental signals to regulate the growth and homeostasis of human cells. This signaling pathway synchronizes many critical cellular processes and is involved in an increasing number of pathological conditions such as diabetes, cancer, obesity, and metabolic syndrome. Here, we review different complications of diabetes that are associated with mTOR complex 1 imbalance. We further discuss pharmacological approaches to treat diabetes complications linked to mTOR deregulation.

Abstract
Despite considerable investigation in diabetic nephropathy (DN) pathogenesis and possible treatments, current therapies still do not provide competent prevention from disease progression to end-stage renal disease (ESRD) in most patients. Therefore, investigating exact molecular mechanisms and important mediators underlying DN may help design better therapeutic approaches for proper treatment. MicroRNAs (MiRNAs) are a class of small non-coding RNAs that play a crucial role in post-transcriptional regulation of many gene expression within the cells and present an excellent opportunity for new therapeutic approaches because their profile is often changed during many diseases, including DN. This review discusses the most important signaling pathways involved in DN and changes in miRNAs profile in each signaling pathway. We also suggest possible approaches for miRNA derived interventions for designing better treatment of DN.

Abstract
To assess the effect of sequential treatment with Vitamin C (VC) and Quercetin (Q) on Nrf2-related oxidative stress in PC3 and DU145 cells, viability was measured by MTT assay. Intracellular ROS levels were determined, using 2'-7'-dichlorodihydrofluorescein diacetate fluorescent as a probe. Nrf2 gene expression was investigated by quantitative reverse transcription polymerase chain reaction, and Nrf2 protein levels were defined by western blot analysis. The activity of glutathione peroxidase (GPx), glutathione reductase (GR), nicotinamide adenine dinucleotide phosphate dehydrogenase quinone 1 (NQO1) and hemeoxygenase 1 (HO-1) enzymes were measured. The IC50 values for VC + Q were 263.03-372.1 µM and 144.2-194.1 µM respectively and 200 µM VC + 50 µM Q (dose no.1) and 100 µM VC + 75 µM Q (dose no.2) were selected. Sequential treatment of PC3 cells led to a significant reduction of Nrf2 mRNA expression and protein levels in addition to a significant reduction of GPx, GR and NQO1 enzymatic activity. Although the data was slightly different for DU145 cells after the treatments, in terms of Nrf2 gene expression, we obtained the same results. Our study revealed the significant effects of sequential treatment with VC + Q on Nrf2 suppression in prostate cancer cells.

Abstract
BACKGROUND Cystic echinococcosis (CE) is a widespread parasitic disease caused by the larval stage of Echinococcus granulosus. Since current methods for the diagnosis of CE are not efficient enough, rapid, and reliable tests are required for the acceleration of CE diagnosis. The present study aimed to produce recombinant B8/1 and B8/2 antigens of E. granulosus and evaluate their sensitivities and specificities separately and simultaneously for the diagnosis of CE. METHODS The recombinant B8/1 and B8/2 antigens were produced and used in an ELISA system for the diagnosis of CE. The sera specimens including 30 sera from pathologically confirmed CE patients, 30 from other non-CE patients, and 30 from healthy controls, were evaluated by the ELISA, using AgB8/1 and AgB8/2. RESULTS The results showed a sensitivity of 93.33%, 90%, and 96.7% for AgB8/1, AgB8/2, and their combination, respectively. The specificities were 91.7%, 93.33%, and 93.33% for AgB8/1, AgB8/2, and their combination, respectively. CONCLUSION Simultaneous usage of AgB8/1 and AgB8/2 increased the test sensitivity for the diagnosis of CE. Furthermore, the specificity of AgB8/1 and AgB8/2 combination was more than AgB8/1 and equal to AgB8/2 alone. The findings revealed that the simultaneous usage of AgB8/1 and AgB8/2 could be a suitable approach for the diagnosis of CE.

Abstract
Background Breast cancer is one of the most prevalent cancers among women. Common cancer treatment methods are not effective enough, and there is a need for a more efficient treatment procedure. Cancer vaccine is a novel immunotherapy method that stimulates humoral and/or cellular immunity against cancer. Placenta-specific protein 1 (PLAC1) is a cancer/testis antigen, prevalent in breast cancer and rarely found in normal tissues. FliC, as a bacterial adjuvant, when fused to PLAC1 can elicit humoral and cellular responses. Therefore, PLAC1-fliC is a chimeric protein, which can be considered a suitable candidate against breast cancer. Methods ProtParam was used to evaluate the physicochemical properties of PLAC1-fliC. Second structures were determined using the GOR V server. PLAC1-fliC 3D structure was modeled by Phyre2, and it was refined using GalaxyWEB. The refined model was submitted to RAMPAGE, PROCHECK, and ProSA-web for validation. Antigenicity and allergenicity of the construct were predicted by ANTIGENpro, VaxiJen, AllergenFP, and SDAP databases. Then MHC-I- and MHC-II-binding epitopes of PLAC1-fliC were forecasted by NetMHC 4.0 and NetMHCII 2.3 Servers. Finally, Ellipro and CTLpred were employed to predict B-cell and cytotoxic T lymphocyte epitopes. Results The construct was evaluated as a stable fusion protein, which could be antigenic and could stimulate B and T cells against breast cancer. Conclusion PLAC1-fliC, as a cancer vaccine candidate, might be suitable and specific for breast cancer, which could evoke humoral and cellular immunity against this type of tumor.

Abstract
BACKGROUND Visceral leishmaniasis (VL) can lead to death in more than 95% of cases if left untreated. Accurate and early diagnosis has an important role in reducing mortality rate of this disease. OBJECTIVE To express recombinant H2B antigen from an Iranian isolate of Leishmania Infantum and evaluate its efficacy in the diagnosis of VL. METHODS The recombinant H2B antigen was produced in a prokaryotic system, and its efficacy for VL diagnosis was evaluated by ELISA. The serum samples from 80 VL patients, 100 individuals from endemic and non-endemic regions of VL, and 58 non-VL patients were collected. VL cases were confirmed based on the clinical sign, positive IFAT (>64), real time PCR, and response to treatment. RESULTS The H2B gene sequence of the Iranian L. infantum isolate had about 4% diversity in comparison with the H2B gene of the L. infantum counterpart. ELISA, using the produced H2B recombinant antigen, showed sensitivity of 71.25% (95% CI: 60.05%-80.82%) and specificity of 69.62% (95% CI: 61.81%-76.68%) regarding VL diagnosis. CONCLUSION Recombinant H2B antigen expressed in the prokaryotic system had suboptimal performance for the serological diagnosis of VL. It seems that the production and expression of recombinant H2B antigen in a eukaryotic system may enhance the performance of this antigen in the diagnosis of VL in Iran.

Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) is a challenging infectious agent worldwide. The ever growing antibiotic resistance has made the researchers to look for new anti-staphylococcal agents. Autolysins are staphylococcal enzymes that lyse bacterial cell wall for cell division. Autolysins can be used as novel enzybiotics (enzymes have antibiotic effects) for staphylococcal infections. LytU is a newly explored autolysin. SH3b is a potent cell wall binding domain that can be fused to lytic enzymes to increase their activity. The aim of this study was to design a novel and efficient fusion enzybiotic that could lyse staphylococcal cell wall peptidoglycan by disrupting the bacteria. LytU-SH3b fusion construct was synthesized and LytU was amplified through the construct, using overhang PCR. The fusion and native forms that had his-tag were synthesized by recombinant technology in Escherichia coli BL21 (DE3) strain and purified utilizing Ni-NTA agarose beads. LytU and LytU-SH3b activity and potency were assessed using plate lysis assay, turbidity reduction assay and minimal inhibitory concentration (MIC) tests. All these tests showed that LytU-SH3b has more activity and potency than LytU. LytU-SH3b has MIC 421 fold lesser than LytU. Finally, LytU-SH3b is a novel and efficient recombinant enzybiotic that can lyse MRSA as an alternative to chemical small molecule antibiotics.

Abstract
BACKGROUND The hyaluronic acid receptor CD44, is a cancer stem cell biomarker, playing important roles in cell adhesion, tumor progression and drug-resistance. Therefore, CD44 is a potential target for cancer treatment and its blockade could result in multi-factorial therapeutic effects. METHODS Nanobodies against CD44 were isolated from a synthetic library with a diversity of 5×1011 CFU/ml using the phage display technique. Three approaches were used for isolation of nanobodies fragments including peptide-, protein- and cell-based panning. RESULTS Nanobodies from cell-based panning displayed more specificity compared to protein or peptide-based panning. Our results show that cell-based panning is the most efficient method for isolation of a specific single domain antibody fragment to CD44 from a synthetic phage displayed library.

Abstract
Background Cystic echinococcosis (CE) is a helminthic disease caused by the larval form of Echinococcus granulosus. In the present study, the B8/2 subunit of antigen B (AgB) of E. granulosus was expressed in E. coli host and then applied in a diagnostic ELISA set up. Methods The DNA sequence of AgB8/2 subunit from E. granulosus was extracted from the GenBank and codon-optimized according to E. coli codon usage. The target sequence was cloned in an expression vector (pGEX-4T-1). The produced antigen was used in an ELISA system, and its performance for the diagnosis of human hydatid cyst was evaluated, using sera from CE and non-CE patients, along with the sera from healthy subjects. Moreover, the diagnostic value of the recombinant protein was compared with native AgB, as well as with a commercial kit. Results Antibodies to hydatid cyst were detected in 27 out of 30 patients corresponding to a sensitivity of 90% (95% CI: 73-98%). Cross-reaction with sera of non-CE subjects was seen in two cases resulted in a specificity of 93.5% (95% CI: 82-98%) for the test. A sensitivity of 87% and specificity of 90% were found for the native form of the antigen, while the ELISA commercial kit had a sensitivity of 97% and specificity of 95%. Conclusion Our data show that rEgAgB8/2 is an appropriate source of antigen for the serological diagnosis of human hydatid cyst. Co-expression of the rEgAgB/2 along with other subunits of AgB may enhance the performances of these antigens for the serodiagnosis of human CE.

Abstract
Study Design Experimental animal study. Purpose This study aimed to assess effects of conditioned medium (CM) of dental pulp-derived stem cells loaded in collagen hydrogel on functional recovery following spinal cord injury (SCI). Overview of Literature SCI affects sensory and motor functions, and behavioral recovery is the most essential purpose of therapeutic intervention. Recent studies have reported that CM from dental pulp-derived stem cells has therapeutic benefits. In addition, collagen hydrogel acts as a drug delivery system in SCI experiments. Methods Stem cells from human exfoliated deciduous teeth (SHEDs) were cultured, and SHED-CM was harvested and concentrated. Collagen hydrogel containing SHED-CM was prepared. The rats were divided into five groups receiving laminectomy, compressive SCI with or without intraspinal injection of biomaterials (SHED-CM), and collagen hydrogel with or without SHED-CM. Basso, Beattie, and Bresnahan (BBB) scoring, inclined plane, cold allodynia, and beam walk tests were performed for 6 weeks to assess locomotor, motor, sensory, and sensory-motor performances, respectively. Results Scores of the rats receiving SHED-CM loaded in collagen hydrogel were significantly better than those of the other injured groups at 1-week post-injury for BBB, 2 weeks for inclined plane, 2 weeks for cold allodynia, and 4 weeks for beam walk tests (p <0.05). The differences remained significant throughout the study. Conclusions Intraspinal administration of SHED-CM loaded in collagen hydrogel leads to improved functional recovery and proposes a cell-free therapeutic approach for SCI.

Abstract
BACKGROUND Differentiating oligodendrocyte precursor cells (OPCs) into oligodendrocytes could be improved by inhibiting signaling pathways such as Wnt and Notch. 9-cis-retinoic acid (9-cis-RA) and 1,25-dihydroxyvitamin D3 (1,25[OH]2D3) can ameliorate oligodendrogenesis. We investigated whether they could increase oligodendrogenesis by inhibiting the Wnt and Notch signaling pathways. METHODS Cortical neural stem cells were isolated from 14-day-old rat embryos and cultured using the neurosphere assay. The cells were treated in 4 different conditions for 1 week: the negative control group received only the basic fibroblast growth factor, the positive control group received only T3 without growth factors, the RA group was treated with 9-cis-RA, and the Vit D3 group was treated with 1,25(OH)2D3. The effects of 9-cis-RA and 1,25(OH)2D3 on the level of the myelin basic protein (MBP) and the gene expression of the SOX10, MBP gene, HES5, and LRP6 were studied using flow cytometry and real-time PCR. The data were analyzed using one-way ANOVA with GraphPad Prism. A P value less than 0.05 was considered significant. RESULTS The mRNA expressions of the SOX10, MBP, and MBP gene were significantly increased in the treated groups compared with the negative control group; the increase was similar in the 9-cis-RA group and the positive control group. Furthermore, 9-cis-RA significantly decreased the expression of the HES5 gene, a Notch signaling pathway transcription factor, and 1,25(OH)2D3 significantly reduced the expression of the LRP6 gene, a Wnt signaling pathway co-receptor. CONCLUSION It seems that 9-cis-RA and 1,25(OH)2D3 are good candidates to improve the differentiation of OPCs into oligodendrocytes.

Abstract
Human Wharton's jelly mesenchymal stem cells (hWJSCs) are multipotent stem cells that could be aggregated into 3D spherules. ITGA4 and ITGA5 genes encode α4 and α5 subunits of integrins, respectively. In this study, we analyzed expression levels of ITGA4 and ITGA5 gene mRNAs in undifferentiated and 3D spherules forming hWJSCs in order to determine their expression pattern for possible future treatment of cancer cells in a co-culture fashion. For the purpose of obtaining hWJSCs, umbilical cords were collected from patients with caesarian section at full term delivery. The cells were then characterized according to cell surface markers using flow cytometry. Furthermore pluripotency of the obtained cells was verified. Subsequently the cells were aggregated in 3D spherules using hanging drop cultures. Expression levels of ITGA4 and ITGA5 gene mRNAs were determined by RT-PCR and Real time PCR, both in the initial undifferentiated cells and those aggregated in the spherules. The obtained hWJSCs demonstrated pluripotency, differentiating to adipogenic and osteogenic cells. They also expressed mesenchymal stem cell surface markers. Following the aggregation of these cells and formation of 3D spherules, mRNA expression levels of both genes were significantly reduced (P < 0.05) compared with the initial undifferentiated state. The results of this study demonstrated that aggregation of hWJSCs into spherules alters their expression of ITGA4 and ITGA5. The implications of such an alteration would require further research.

Abstract
Due to the considerable role of N-cadherin in cancer metastasis, tumor growth, and progression, inhibition of this protein has been highly regarded in recent years. Although ADH-1 has been known as an appropriate inhibitor of N-cadherin in clinical trials, its chemical nature and binding mode with N-cadherin have not been precisely specified yet. Accordingly, in this study, quantum mechanics calculations were used to investigate the chemical nature of ADH-1. These calculations clarify the molecular properties of ADH-1 and determine its reactive sites. Based on the results, the oxygen atoms are suitable for electrophilic reactivity, while the hydrogen atoms that are connected to nitrogen atoms are the favorite sites for nucleophilic reactivity. The higher electronegativity of the oxygen atoms makes them the most reactive portions in this molecule. Molecular docking and molecular dynamics (MD) simulation have also been applied to specify the binding mode of ADH-1 with N-cadherin and determine the important residues of N-cadherin involving in the interaction with ADH-1. Moreover, the verified model by MD simulation has been studied to extract the free energy value and find driving forces. These calculations and molecular electrostatic potential map of ADH-1 indicated that hydrophobic and electrostatic interactions are almost equally involved in the implantation of ADH-1 in the N-cadherin binding site. The presented results not only enable a closer examination of N-cadherin in complex with ADH-1 molecule, but also are very beneficial in designing new inhibitors for N-cadherin and can help to save time and cost in this field.

Abstract
BACKGROUND Over the past few years, the rapid use of high frequency electromagnetic fields like mobile phones has raised global concerns about the negative health effects of its use. Adaptive response is the ability of a cell or tissue to better resist stress damage by prior exposure to a lesser amount of stress. This study aimed to assess whether radiofrequency radiation can induce adaptive response by changing the antioxidant balance. MATERIALS AND METHODS In order to assess RF-induced adaptive response in tissues, we evaluated the level of GSH and the activity of GR in liver. 50 rats were divided into 5 groups. Three groups were pre-exposed to 915 MHz RF radiation, 4 hours per day for one week at different powers, as low, medium and high. 24 hours after the last exposure to radiation, they were exposed to 4 Gy sublethal dose of gamma radiation and then sacrificed after 5 hours. Their livers were removed, washed and were kept at -80o C until used. RESULTS Our finding showed that pre-exposure to 915 MHz radiofrequency radiation with specific power could induce adaptive response in liver by inducing changes in the activity and level of antioxidant enzymes. CONCLUSION It can be concluded that pre-exposure to microwave radiation could increase the level of GSH and the activity of GR enzyme, although these increases were seen just in low power group, and the GR activity was indicated in medium power group. This increase protects tissue from oxidative damage induced by sublethal dose of gamma radiation.

Abstract
BACKGROUND Discriminating latent tuberculosis infection (LTBI) from active TBI may be challenging. The objective of this study was to produce the recombinant L-alanine dehydrogenase (AlaDH) antigen and evaluate individuals with LTBI, those with active TBI, and uninfected individuals by enzyme-linked immunospot assay (ELISPOT) in order to distinguish LTBI from active TBI. METHODS This exploratory study was performed in the Iranian city of Shiraz from 2014 to 2015. The study population (N=99) was divided into 3 groups: individuals with newly diagnosed active TBI (n=33), their household contacts (n=33), and controls (n=33). AlaDH was produced through PCR and cloning methods. The diagnostic characteristics of AlaDH vs. ESAT-6/CFP-10 were evaluated in responses to interferon-γ (IFN-γ) and interleukin-2 (IL-2) with ELISPOT. Differences between the groups were assessed with the Kruskal-Wallis and Mann-Whitney tests for nonparametric data analysis. The statistical analyses were performed with SPSS, version 16. RESULTS IFN-γ responses to both ESAT-6/CFP-10 (P=0.81) and AlaDH (P=0.18) revealed that there were no significant differences between the individuals with LTBI and those with active TBI. The same results were determined for IL-2 responses to ESAT-6/CFP-10 between the 2 groups, while significantly higher IL-2 responses to AlaDH were observed in LTBI than in active TBI. According to the ROC curve analysis, a cutoff value of 275 SFC showed sensitivity of 75.8% and specificity of 78.8% for distinguishing LTBI from active TBI by IL-2 responses to AlaDH. CONCLUSION The current study suggests that it may be possible to discriminate LTBI from active TBI by IL-2 responses to AlaDH.

Abstract
The balance between the production and elimination of reactive oxygen species (ROS) is essential in determining whether cells survive or undergo apoptosis. Nuclear factor erythroid 2-related factor 2 (Nrf2) may act as a sensor for electrophilic stress, thus regulating the intracellular antioxidant response. The present study investigated the role of vitamin C (VC) and quercetin (Q) in the induction of Nrf2-mediated oxidative stress in cancer cells. An MTT assay was conducted to examine the anti-proliferative effects of VC and Q. Reverse transcription-quantitative polymerase chain reaction and western blot analysis were performed to determine the messenger RNA (mRNA) and protein expression of Nrf2, respectively. The activity of nicotinamide adenine dinucleotide phosphate dehydrogenase quinone 1, heme oxygenase 1, glutathione peroxidase, glutathione reductase and reduced glutathione were measured by spectrophotometric analysis. Intracellular generation of ROS was determined using 2'-7'-dichlorodihydrofluorescein diacetate fluorescent probes. The results demonstrated that the cytotoxicity (50% inhibitory concentration) of VC and Q were 271.6-480.1 and 155.1-232.9 µM, respectively. Additionally, there was a significant decrease in the expression of Nrf2 mRNA and protein levels following the treatment of breast cancer cells with VC and Q (P=0.024). Following treatment with VC and Q, the nuclear/cytosolic Nrf2 ratio was reduced by 1.7-fold in MDA-MB 231 cells, 2-fold in MDA-MB 468 cells, 1.4-fold in MCF-7 cells and 1.2 fold in A549 cells. Sequential treatment with VC and Q decreased endogenous production of ROS in a dose-dependent manner (P=0.027). The results of the current study suggest that VC and Q treatment may be developed as an adjuvant for patients with cancer and overexpression of Nrf2.
