There are several studies about the effects of NPs on dermal fibroblast or keratino- cytes, but very little attention has been directed towards adipose-derived mesenchymal stem cells (ASCs). A previous study has revealed that ZnO-NPs restricted the migration capability of ASCs. However, the potential toxicity of these NPs on ASCs is not well un- derstood. This study intends to evaluate the effects of ZnO-NPs on subcutaneous ASCs. <br /><strong>Materials and Methods</strong><br />In this experimental study, In order to assess toxicity, we ex- posed rat ASCs to ZnO-NPs at concentrations of 10, 50, and 100 µg/ml for 48 hours. Tox- icity was evaluated by cell morphology changes, cell viability assay, as well as apoptosis and necrosis detection. <br /><strong>Results</strong><br />ZnO-NPs concentration dependently reduced the survival rates of ASCs as re- vealed by the trypan blue exclusion and 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazo- lium-bromide (MTT) tests. ZnO-NPs, at concentrations of 10 and 50 µg/ml, induced a significant increase in apoptotic indices as shown by the annexin V test. The concentration of 10 µg/ml of ZnO-NPs was more toxic. <br /><strong>Conclusion</strong><br />Lower concentrations of ZnO-NPs have toxic and apoptotic effects on subcutaneous ASCs. We recommend that ZnO-NPs be used with caution if there is a dermatological problem.https://www.celljournal.org/article_250299_9986fbc2b2c1810201b9244baa53dac6.pdfRoyan Institute, Iranian Academic Center for Education Culture and Research (ACECR)Cell Journal (Yakhteh)2228-580617320151001The Protective Effects of Gadolinum Chloride on Pneumotoxic Effects of Styrene in Rat42242825030010.22074/cellj.2015.3ENMohammad Reza ArabCell and Molecular Research Center, Department of Anatomical Sciences, Faculty of Medicine, Zahedan

GdCl3 (N=5) and v. normal saline (Nor.Sal, as a solvent of GdCl3, N=5). Normal saline, as a sham control group, was otherwise treated identically. Rats from the experimental groups were exposed to St in an exposure chamber for 6 days/week, 4 hours/day for up to 3 weeks. At the end of the experi- ment, rats from all groups were killed by deep anesthesia. Their lungs were removed, then fixed in formalin and weighed. Tissue samples were processed routinely and sections stained by the hematoxylin and eosin (H&E) and periodic acid Schiff (PAS) methods. We measured the thicknesses of the respiratory epithelia and interalveolar septa. Obtained data were ana- lyzed by ANOVA, the Tukey test and the paired t test. <br /><strong>Results</strong><br />Shedding of apical cytoplasm in the bronchiole was a prominent feature of the St group. PAS staining revealed histochemical changes in goblet cells in the epithelium of the St group. While there were no significant changes in lung weights and respiratory epithelial thicknesses between all studied groups, statistical analysis showed a significant alteration in the thickness of interalveolar septa in the St and St+GdCl3 group compared to the control groups (P < 0.001). <br /><strong>Conclusion</strong><br />Styrene induced structural and histochemical changes in bronchiole, interalveolar septa and alveolar organization in the rats’ lungs. Gadolinium appeared to partially reduce the toxic effects of styrene on the lungs.https://www.celljournal.org/article_250300_e6f1e4616163bef5b2582c7dcd97639c.pdfRoyan Institute, Iranian Academic Center for Education Culture and Research (ACECR)Cell Journal (Yakhteh)2228-580617320151001Cell Attachment and Proliferation of Human Adipose-Derived Stem Cells on PLGA/Chitosan Electrospun Nano-Biocomposite42943725030110.22074/cellj.2015.4ENShahnaz RazaviDepartment of Anatomical Sciences and Molecular Biology, School of Medicine, Isfahan University of

Despite the fact that various methods such as lipofection and electroporation have been applied to transfer the gene of interest (GOI) into the target cell line, however, there are few re- ports that compare all parameters, which influence transfection efficiency. In this study, we examine all parameters that affect the efficiency of electroporation and lipofection for transient and long-term gene expression in three different cell lines to introduce the best method and determinant factor. <br /><strong>Materials and Methods</strong><br />In this experimental study, both electroporation and lipofection approaches were employed for genetic modification. pCAG-EGFP was applied for tran- sient expression of green fluorescent protein in two genetically different hESC lines, Roy- an H5 (XX) and Royan H6 (XY), as well as human foreskin fibroblasts (hFF). For long-term EGFP expression VASA and OLIG2 promoters (germ cell and motoneuron specific genes, respectively), were isolated and subsequently cloned into a pBluMAR5 plasmid backbone to drive EGFP expression. Flow cytometry analysis was performed two days after trans- fection to determine transient expression efficiency. Differentiation of drug resistant hESC colonies toward primordial germ cells (PGCs) was conducted to confirm stable integration of the transgene. <br /><strong>Results</strong><br />Transient and stable expression suggested a variable potential for different cell lines against transfection. Analysis of parameters that influenced gene transformation ef- ficiency revealed that the vector concentrations from 20-60 μg and the density of the sub- jected cells (5×105and 1×106cells) were not as effective as the genetic background and voltage rate. The present data indicated that in contrast to the circular form, the linearized vector generated more distinctive drug resistant colonies. <br /><strong>Conclusion</strong><br />Electroporation was an efficient tool for genetic engineering of hESCs compared to the chemical method. The genetic background of the subjected cell line for transfection seemed to be a fundamental factor in each gene delivery method. For each cell line, optimum voltage rate should be calculated as it has been shown to play a crucial role in cell death and rate of gene delivery.https://www.celljournal.org/article_250302_7533cb162b5b31e1ff8a6d927c06403f.pdfRoyan Institute, Iranian Academic Center for Education Culture and Research (ACECR)Cell Journal (Yakhteh)2228-580617320151001Genome-Wide Analysis of Oceanimonas sp.

In this study, we aimed to investigate the impact of predicted miRNAs and their target genes on the myoblast to myocyte differentiation process. <br /><strong>Materials and Methods</strong><br />This experimental study was conducted on the C2C12 cell line. Using a bioinformatics approach, miR-214 and miR-135 were selected according to their targets as potential factors in myoblast to myocyte differentiation induced by 3% horse serum. Immunocytochemistry (ICC) was undertaken to confirm the differentiation process and quantitative real-time polymerase chain reaction (PCR) to determine the expression level of miRNAs and their targets. <br /><strong>Results</strong><br />During myoblast to myocyte differentiation, miR-214 was significantly down- regulated while miRNA-135, Irs2, Akt2 and Insr were overexpressed during the process. <br /><strong>Conclusion</strong><br />miR-214 and miR-135 are potential regulators of myogenesis and are involved in skeletal muscle development through regulating the IRS/PI3K pathway.https://www.celljournal.org/article_250304_012df60aa3e0559e17473927c236180e.pdfRoyan Institute, Iranian Academic Center for Education Culture and Research (ACECR)Cell Journal (Yakhteh)2228-580617320151001Upregulation of RHOXF2 and ODF4 Expression in Breast Cancer Tissues47147725030510.22074/cellj.2015.8ENGolnesa Kazemi-OulaDepartment of Medical Genetics, Tehran University of Medical Sciences, Tehran, Iran;Genetics Research Center, University of Social Welfare and Rehabilitation Sciences, Tehran, IranSoudeh Ghafouri-FardDepartment of Medical Genetics, Shahid Beheshti University of Medical Sciences, Tehran, IranMaryam Beigom MobasheriDepartment of Medical Genetics, Tehran University of Medical Sciences, Tehran, IranLobat Geranpayeh4Department of Surgery, Sina Hospital, Tehran University of Medical Sciences, Tehran, IranMohammad Hossein ModarressiDepartment of Medical Genetics, Tehran University of Medical Sciences, Tehran, IranJournal Article19700101<strong>Objective</strong><br />During the past decade, the importance of biomarker discovery has been highlighted in many aspects of cancer research. Biomarkers may have a role in early detection of cancer, prognosis and survival evaluation as well as drug response. Cancer-testis antigens (CTAs) have gained attention as cancer biomarkers because of their expression in a wide variety of tumors and restricted expression in testis. The aim of this study was to find putative biomarkers for breast cancer. <br /><strong>Materials and Methods</strong><br />In this applied-descriptive study, the expression of 4 CTAs, namely acrosin binding protein (ACRBP), outer dense fiber 4 (ODF4), Rhox homeobox family member 2 (RHOXF2) and spermatogenesis associated 19 (SPATA19) were ana- lyzed at the transcript level in two breast cancer lines (MCF-7 and MDA-MB-231), 40 invasive ductal carcinoma samples and their adjacent normal tissues as well as 10 fibroadenoma samples by means of quantitative real-time reverse transcription polymerase chain reaction (RT-PCR). <br /><strong>Results</strong><br />All four genes were expressed in both cell lines. Expression of ODF4 and RH- OXF2 was detected in 62.5% and 60% of breast cancer tissues but in 22.5 and 17.5% of normal tissues examined respectively. The expression of both RHOXF2 and ODF4 was upregulated in cancerous tissues compared with their normal adjacent tissues by 3.31 and 2.96-fold respectively. The expression of both genes was correlated with HER2/neu overexpression. RHOXF2 expression but not ODF4 was correlated with higher stages of tumors. However, no significant association was seen between expression patterns and estrogen and progesterone receptors status. <br /><strong>Conclusion</strong><br />ODF4 and RHOXF2 are proposed as putative breast cancer biomarkers at the transcript level. However, their expression at protein level should be evaluated in future studies.https://www.celljournal.org/article_250305_4dd30117432bc6ddf5f1d9eae8001e0d.pdfRoyan Institute, Iranian Academic Center for Education Culture and Research (ACECR)Cell Journal (Yakhteh)2228-580617320151001Expression of COLLAGEN 1 and ELASTIN Genes in Mitral Valvular Interstitial Cells within Microfiber Reinforced Hydrogel47848825030610.22074/cellj.2015.22ENMaryam EslamiDepartment of Biology, Science and Research Branch, Islamic Azad University, Tehran, Iran;Department of Genetics,Tehran Medical Sciences Branch, Islamic Azad University, Tehran, Iran;Applied Biotechnology Research Center, Tehran MGholamreza JavadiDepartment of Biology, Science and Research Branch, Islamic Azad University, Tehran, IranNasser Agdami4Department of Stem Cells and Developmental Biology, Cell Science Research Center, Royan Institute for

By mimicking the main tissue structures and properties of heart valve, tissue engineering offers new options for the replacements. Applying an appropriate scaffold in fabricating tissue-engineered heart valves (TEHVs) is of importance since it affects the secretion of the main extracellular matrix (ECM) components, collagen 1 and elastin, which are crucial in providing the proper mechanical properties of TEHVs. <br /><strong>Materials and Methods</strong><br />Using real-time polymerase chain reaction (PCR) in this experi- mental study, the relative expression levels of COLLAGEN 1 and ELASTIN were obtained for three samples of each examined sheep mitral valvular interstitial cells (MVICs)-seeded onto electrospun poly (glycerol sebacate) (PGS)-poly (ε-caprolactone) (PCL) microfibrous, gelatin and hyaluronic acid based hydrogel-only and composite (PGS-PCL/hydrogel) scaffolds. This composite has been shown to create a synthetic three-dimensional (3D) microenvironment with appropriate mechanical and biological properties for MVICs. <br /><strong>Results</strong><br />Cell viability and metabolic activity were similar among all scaffold types. Our results showed that the level of relative expression of COLLAGEN 1 and ELASTIN genes was higher in the encapsulated composite scaffolds compared to PGS-PCL-only and hydrogel-only scaffolds with the difference being statistically significant (P < 0.05). <br /><strong>Conclusion</strong><br />The encapsulated composite scaffolds are more conducive to ECM secretion over the PGS-PCL-only and hydrogel-only scaffolds. This composite scaffold can serve as a model scaffold for heart valve tissue engineering.https://www.celljournal.org/article_250306_773792f39b3983b27142bdbb7eb2b40d.pdfRoyan Institute, Iranian Academic Center for Education Culture and Research (ACECR)Cell Journal (Yakhteh)2228-580617320151001Effect of Nanosilver Particles on Procaspase-3 Expression in Newborn Rat Brain48949325030710.22074/cellj.2015.23ENMostafa GanjuriDepartment of Biology, School of Sciences, University of Isfahan, Isfahan, IranJamal MoshtaghianDepartment of Biology, School of Sciences, University of Isfahan, Isfahan, IranJournal Article19700101<strong>Objective</strong><br />Nanotechnology focuses on materials having at least one dimension of less than 100 nanometers. Nanomaterials such as Nanosilver (NS) have unique physical and chemical properties such as size, shape, surface charge. NS particles are thought to in- duce neuronal degeneration and necrosis in the brain. It has been reported that NS parti- cles generate free radicals and oxidative stress which alters gene expression and induces apoptosis. This study was designed to evaluate whether the detrimental effect of NS parti- cles is through the activation of Procaspase-3 during fetal neural development. <br /><strong>Materials and Methods</strong><br />In this experimental study, thirty Wistar female rats at day one of pregnancy were semi-randomly distributed into three groups of ten. Group 1, the control group, had no treatment. From day 1 to the end of pregnancy, groups 2 and 3 received 1 and 10 ppm NS respectively via drinking water. Newborn rats were sacrificed immediately after birth and their brains were dissected and kept frozen. Total RNA, extracted from brain homogenates, was reverse transcribed to cDNA. Quantitative real-time polymerase chain reaction (PCR) analysis was undertaken to estimate the expression level of Procaspase-3. <br /><strong>Results</strong><br />Developmental exposure to NS induced neurotoxicity and apoptosis. This corre- lated with a significant increase in Procaspase-3 expression level especially at 10 ppm NS. <br /><strong>Conclusion</strong><br />The pro-apoptotic activity of NS in cells is likely to due to the dysregula- tion of Procaspase-3.https://www.celljournal.org/article_250307_cc12b4685b10aa1c66ce5a4c0c0b0ffd.pdfRoyan Institute, Iranian Academic Center for Education Culture and Research (ACECR)Cell Journal (Yakhteh)2228-580617320151001Identification of Reliable Reference Genes for Quantification of MicroRNAs in Serum Samples of Sulfur Mustard-Exposed Veterans49450125030810.22074/cellj.2015.9ENSedigheh GharbiDepartment of Molecular Genetics, Faculty of Biological Sciences, Tarbiat Modares University, Tehran, Iran;Department of Biology, Faculty of Sciences, Shahid Bahonar University of Kerman,

Circulating microRNAs (miRNAs) are promising biomarkers for disease diagnosis and prognosis. Accurate normalization using appropriate reference genes, is a critical step in miRNA expression studies. In this study, we aimed to identify appropriate reference gene for microRNA quantification in serum samples of SM victims. <br /><strong>Materials and Methods</strong><br />In this case and control experimental study, using quantitative real-time polymerase chain reaction (qRT-PCR), we evaluated the suitability of a panel of small RNAs including SNORD38B, SNORD49A, U6, 5S rRNA, miR-423-3p, miR-191, miR-16 and miR-103 in sera of 28 SM-exposed veterans of Iran-Iraq war (1980-1988) and 15 matched control volunteers. Different statistical algorithms including geNorm, Normfinder, best-keeper and comparative delta-quantification cycle (Cq) method were employed to find the least variable reference gene. <br /><strong>Results</strong><br />miR-423-3p was identified as the most stably expressed reference gene, and miR- 103 and miR-16 ranked after that. <br /><strong>Conclusion</strong><br />We demonstrate that non-miRNA reference genes have the least stabil- ity in serum samples and that some house-keeping miRNAs may be used as more reliable reference genes for miRNAs in serum. In addition, using the geometric mean of two reference genes could increase the reliability of the normalizers.https://www.celljournal.org/article_250308_ab8aedc02e4047bfef3137d1a5c73a77.pdfRoyan Institute, Iranian Academic Center for Education Culture and Research (ACECR)Cell Journal (Yakhteh)2228-5806173201510016-Methoxy Podophyllotoxin Induces Apoptosis via Inhibition of TUBB3 and TOPIIA Gene Expressions in 5637 and K562 Cancer Cell Lines50250925030910.22074/cellj.2015.10ENIman SadeghiDepartment of Genetics, Faculty of Biological Sciences, Tarbiat Modares University, Tehran, IranMehrdad BehmaneshDepartment of Genetics, Faculty of Biological Sciences, Tarbiat Modares University, Tehran, Iran0000-0002-3901-304XNajmeh Ahmadian ChashmiDepartment of Plant Biology, Faculty of Biological Sciences, Tarbiat Modares University, Tehran, IranMohsen SharifiDepartment of Plant Biology, Faculty of Biological Sciences, Tarbiat Modares University, Tehran, IranBahram Mohammad SoltaniDepartment of Genetics, Faculty of Biological Sciences, Tarbiat Modares University, Tehran, IranJournal Article19700101<strong>Objective</strong><br />Podophyllotoxin (PTOX), a natural compound in numerous plants, contains remarkable biological properties that include anti-tumor, anti-viral such as anti-human im- munodeficiency virus (HIV) activities. In order to avoid its adverse effects, various com- pounds have been derived from PTOX. 6-methoxy PTOX (MPTOX) is one of the natural PTOX derivatives with an extra methoxy group. MPTOX is mostly isolated from the Linum species. This study has sought to determine the biological effects of MPTOX on cancer cell lines, 5637 and K562. <br /><strong>Materials and Methods</strong><br />In this experimental study, we treated the 5637 and K562 cancer cell lines with MPTOX in a doseand time-dependent manner. Apoptosis was examined by flow cytometry and viability rate was analyzed by the MTT assay. Expressions of the tubulin (TUBB3) and topoisomerase II (TOPIIA) genes were determined by real-time poly- merase chain reaction (PCR). <br /><strong>Results</strong><br />Treatment with MPTOX led to significant induction of apoptosis in cancer cells compared to control cells. Gene expression analysis showed reduced levels of TUBB3 and TOPIIA mRNA following MPTOX treatment. <br /><strong>Conclusion</strong><br />MPTOX inhibited TUBB3 and TOPIIA gene expression and subsequently induced cell death through apoptosis. These results suggested that MPTOX could be considered a potential anti-tumor agent.https://www.celljournal.org/article_250309_2f7d56d5db78106e26e76a04603ce153.pdfRoyan Institute, Iranian Academic Center for Education Culture and Research (ACECR)Cell Journal (Yakhteh)2228-580617320151001Association of The Common CYP1A1*2C Variant (Ile462Val Polymorphism) with Chronic Myeloid Leukemia (CML) in Patients Undergoing Imatinib Therapy51051925031010.22074/cellj.2015.11ENSamyuktha LakkireddyCentre for Biotechnology and Bioinformatics, School of Life Sciences, Jawaharlal Nehru Institute of Advanced

The association be- tween single nucleotide polymorphisms (SNPs) in CYP1A1 and pathogenesis of chronic myeloid leukemia (CML) has been investigated in several studies, but the results observed vary based on varied risk factors. The objective of this study was to investigate the risk factors associated with the CYP1A1*2C [rs1048943: A>G] polymorphism in CML patients and its role in therapeutic response to imatinib mesylate (IM) affecting clinico-pathological parameters, in the Indian population. <br /><strong>Materials and Methods</strong><br />In this case-control study, CYP1A1*2C was analysed in CML patients. After obtaining approval from the Ethics Committee of oncology hospital, we collected blood samples from 132 CML patients and 140 matched controls. Genom- ic DNA was extracted and all the samples were analysed for the presence of the CYP1A1*2C polymorphism using allele-specific polymerase chain reaction, and we examined the relationship of genotypes with risk factors such as gender, age, phase of the disease and other clinical parameters. <br /><strong>Results</strong><br />We observed a significant difference in the frequency distribution of CYP1A1*2C genotypes AA (38 vs. 16%, P=0.0001), AG (57 vs. 78%, P=0.0002) and GG (5 vs. 6%, P=0.6635) between patients and controls. In terms of response to IM therapy, significant variation was observed in the frequencies of AA vs AG in major (33 vs 67%) and poor (62 vs 31%) hematological responders, and AA vs AG in major (34 vs. 65%) and poor (78 vs. 22%) cytogenetic responders. However, the patients with the GG homozygous genotype did not show any significant therapeutic outcome. <br /><strong>Conclusion</strong><br />The higher frequency of AG in controls indicates that AG may play a protec- tive role against developing CML. We also found that patients with the AG genotype showed favorable treatment response towards imatinib therapy, indicating that this polymorphism could serve as a good therapeutic marker in predicting response to such therapy.https://www.celljournal.org/article_250310_ea29a679f098f1bd855fd5c4ebc76fc8.pdfRoyan Institute, Iranian Academic Center for Education Culture and Research (ACECR)Cell Journal (Yakhteh)2228-580617320151001High-Level Expression, Purification and Characterization of A Recombinant Plasmodium vivax Apical Membrane Antigen 1: Implication for vivax Malaria Vaccine Development52053125031110.22074/cellj.2015.12ENMaryam SalavatifarDepartment of Biology, Science and Research Branch, Islamic Azad University, Tehran, IranSedigheh ZakeriMalaria and Vector Research Group (MVRG), Biotechnology Research Center (BCR), Pasteur Institute of Iran,

The correct conformation of this protein appears to be necessary for the stimulation of parasite-inhibitory responses, and these responses, in turn, seem to be antibody-mediated. Therefore, in the present investigation, we expressed the Plasmodium vivax AMA-1 (PvAMA-1) ectodomain in Escherichia coli (E. coli), purified it using standard procedures and characterized it to determine its biological activities for it to be used as a potential target for developing a protective and safe vivax malaria vaccine. <br /><strong>Materials and Methods</strong><br />In this experimental investigation, the ectodomain of PvAMA-1 antigen (GenBank accession no. JX624741) was expressed in the E. coli M15pQE30 expression system and purified with immobilized-metal affinity chromatography. The correct conformation of the recombinant protein was evaluated by Western blotting and indirect immunofluorescence antibody (IFA) test. In addition, the immunogenic properties of PvAMA-1 were evaluated in BALB/c mice with the purified protein emulsified in Freund’s adjuvant. <br /><strong>Results</strong><br />In the present study, the PvAMA-1 ectodomain was expressed at a high-level (65 mg/L) using a bacterial system. Reduced and non-reduced sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) as well as Western blot analysis confirmed the appropriate conformation and folding of PvAMA-1. The evaluation of immunogenic properties of PvAMA-1 showed that both T helper-1 and 2 cells (Th1 and Th2) responses were present in mice after three immunizations and persisted up to one year after the first immunization. Moreover, the antibodies raised against the recombinant PvAMA-1 in injected mice could recognize the native protein localized on P. vivax parasites. <br /><strong>Conclusion</strong><br />We demonstrate that our recombinant protein had proper conformation and folding. Also, there were common epitopes in the recombinant forms corresponding to native proteins. These results; therefore, indicate that the expressed PvAMA-1 has the potential to be used as a vivax malaria vaccine.https://www.celljournal.org/article_250311_8f5482aa580497203c81acfc44be96ee.pdfRoyan Institute, Iranian Academic Center for Education Culture and Research (ACECR)Cell Journal (Yakhteh)2228-580617320151001Suppressive Effects of Resveratrol Treatment on The Intrinsic Evoked Excitability of CA1 Pyramidal Neurons53253925031210.22074/cellj.2015.13ENGholamhossein MeftahiNeuroscience Research Center and Department of Physiology, Medical School, Shahid Beheshti University of

Despite a growing body of evidence indicating that resveratrol induces changes in neu- ronal function, little effort, if any, has been made to investigate the cellular effect of res- veratrol treatment on intrinsic neuronal properties. <br /><strong>Materials and Methods</strong><br />This experimental study was performed to examine the acute effects of resveratrol (100 µM) on the intrinsic evoked responses of rat Cornu Ammonis (CA1) pyramidal neurons in brain slices, using whole cell patch clamp re- cording under current clamp conditions. <br /><strong>Results</strong><br />Findings showed that resveratrol treatment caused dramatic changes in evoked responses of pyramidal neurons. Its treatment induced a significant (P < 0.05) increase in the after hyperpolarization amplitude of the first evoked action potential. Resveratrol-treated cells displayed a significantly broader action potential (AP) when compared with either control or vehicle-treated groups. In addition, the mean instantaneous firing frequency between the first two action potentials was significantly lower in resveratrol-treated neurons. It also caused a significant reduction in the time to maximum decay of AP. The rheobase current and the utilization time were both significantly greater following resveratrol treatment. Neurons exhibited a significantly depolarized voltage threshold when exposed to resveratrol. <br /><strong>Conclusion</strong><br />Results provide direct electrophysiological evidence for the inhibitory effects of resveratrol on pyramidal neurons, at least in part, by reducing the evoked neural activity.https://www.celljournal.org/article_250312_022df8e53816572b97d48a7a1d614915.pdfRoyan Institute, Iranian Academic Center for Education Culture and Research (ACECR)Cell Journal (Yakhteh)2228-580617320151001Fibroblast Growth Factor-2 Enhanced The Recruitment of Progenitor Cells and Myelin Repair in Experimental Demyelination of Rat Hippocampal Formations54045625031310.22074/cellj.2015.14ENMahdieh AzinJavad Mirnajafi-ZadehMohammad JavanJournal Article19700101<strong>Objective</strong><br />Hippocampal insults have been observed in multiple sclerosis (MS) patients. Fibroblast growth factor-2 (FGF2) induces neurogenesis in the hippocampus and en- hances the proliferation, migration and differentiation of oligodendrocyte progenitor cells (OPCs). In the current study, we have investigated the effect of FGF2 on the processes of gliotoxin induced demyelination and subsequent remyelination in the hippocampus. <br /><strong>Materials and Methods</strong><br />In this experimental study adult male Sprague-Dawley rats re- ceived either saline or lysolecithin (LPC) injections to the right hippocampi. Animals re- ceived intraperitoneal (i.p.) injections of FGF2 (5 ng/g) on days 0, 5, 12 and 26 post-LPC. Expressions of myelin basic protein (Mbp) as a marker of myelination, Olig2 as a marker of OPC proliferation, Nestin as a marker of neural progenitor cells, and glial fibrillary acidic protein (Gfap) as a marker of reactive astrocytes were investigated in the right hippocampi by reverse transcriptase-polymerase chain reaction (RT-PCR). <br /><strong>Results</strong><br />There was reduced Mbp expression at seven days after LPC injection, in- creased expressions of Olig2 and Nestin, and the level of Gfap did not change. FGF2 treatment reversed the expression level of Mbp to the control, significantly enhanced the levels of Olig2 and Nestin, but did not change the level of Gfap. At day-28 post- LPC, the expression level of Mbp was higher than the control in LPC-treated animals that received FGF2. The levels of Olig2, Nestin and Gfap were at the control level in the non-treated LPC group but significantly higher in the FGF2-treated LPC group. <br /><strong>Conclusion</strong><br />FGF2 enhanced hippocampal myelination and potentiated the recruitment of OPCs and neural stem cells (NSCs) to the lesion area. Long-term application of FGF2 might also enhance astrogliosis in the lesion site.https://www.celljournal.org/article_250313_971450a1ec48d16102e49c0fb4ba2ac8.pdfRoyan Institute, Iranian Academic Center for Education Culture and Research (ACECR)Cell Journal (Yakhteh)2228-580617320151001The Relationship between Seminal Melatonin with Sperm Parameters, DNA Fragmentation and Nuclear Maturity in Intra-Cytoplasmic Sperm Injection Candidates54755325031410.22074/cellj.2015.15ENMina SharbatoghliDepartment of Embryology, Reproductive Biomedicine Research Center, Royan Institute for Reproductive

Because of the presence of melatonin in semen and the mem- brane melatonin receptor in spermatozoa, the impact of melatonin on the regulation of male infertility is still questionable. The aim of this study was to determine the effects of endogenous melatonin on human semen parameters (sperm concentration, motility and normal morphology), DNA fragmentation (DF) and nuclear maturity. <br /><strong>Materials and Methods</strong><br />In this clinical prospective study, semen samples from 75 infer- tile men were routinely analyzed and assessed for melatonin and total antioxidant capac- ity (TAC) levels using the enzyme-linked immunosorbent assay (ELISA) and colorimetric assay kits, respectively. DF was examined by the sperm chromatin dispersion (SCD) test. Acidic aniline blue staining was used to detect chromatin defects in the sperm nuclei. <br /><strong>Results</strong><br />There was no significant correlation between seminal plasma melatonin and TAC with sperm parameters and nuclear maturity. However, we observed a positive significant correlation between DF and melatonin level (r=0.273, P < 0.05). <br /><strong>Conclusion</strong><br />Melatonin in seminal plasma is positively correlated with damaged sperm DNA of infertile patients. The mechanism of this phenomenon needs further study.https://www.celljournal.org/article_250314_ef043ffe99a36d4479eb4455c9434b05.pdfRoyan Institute, Iranian Academic Center for Education Culture and Research (ACECR)Cell Journal (Yakhteh)2228-580617320151001Salivary Interferon Gamma and Interleukin-4 Levels in Patients Suffering from Oral Lichen Planus55455825031510.22074/cellj.2015.16ENHossein MalekzadehDepartment of Oral Medicine, Faculty of Dentistry, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, IranMaryam RobatiDepartment of Oral Medicine, Faculty of Dentistry, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, IranHojatollah YousefimaneshDepartment of Periodontics, Faculty of Dentistry, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, IranMehri Ghafourian BoroujerdniaDepartment of Immunology, Faculty of Medicine, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, IranReza NadripourDepartment of Periodontics, Faculty of Dentistry, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, IranJournal Article19700101<strong>Objective</strong><br />Oral lichen planus (OLP) is a chronic inflammatory disease. Immunological factor may act as etiological factor. The cellular immune cells such as T cells are impor- tant in pathogenesis. Interferon gamma (IFN-γ) and interleukin 4 (IL-4) are secreted by T-helper 1 (Th1) and Th2, respectively. The aim of this study was to investigate the cor- relation between salivary levels of IFN-γ and IL-4 with OLP. <br /><strong>Materials and Methods</strong><br />This case control study included sixty three Iranian OLP patients who were selected from the Department of Oral Medicine of Ahvaz Jundishapur University of Medical Sciences from January to July 2013. An equal number of healthy volunteers were also selected as a control group. The OLP patients were then divided into two follow- ing sub-groups: reticular (n=30) and erythematous/ulcerative (n=33). All patients had no systemic disease and received no medication. IFN-γ and IL-4 levels in whole unstimulated saliva (WUS) were measured using the enzyme-linked immunosorbent assay (ELISA) test. Data analysis was done using t test, ANOVA, least significant difference (LSD) test, and the Kruskal-Wallis test. <br /><strong>Results</strong><br />Reticular OLP patients showed higher salivary IFN-γ (7.74 ± 0.09 pg/ml ) and IL-4 (3.876 ± 0.05 pg/ml) levels compared with the control group, indicating that difference was significant. Salivary IFN-γ/IL-4 ratio significantly increased compared with control group (P=0.042).

The objective of this experiment is to investigate the methylation variation of 10 CpG sites in the Egf promoter region and their relevance to Egf expression during rat liver regenera- tion. As a follow up of our previous study, rat liver tissue was collected after rat 2/3 partial hepatectomy (PH) during the re-organization phase (from days 14 to days 28). Liver DNA was extracted and modified by sodium bisulfate. The methylation status of 10 CpG sites in Egf promoter region was determined using bisulfite sequencing polymerase chain reaction (PCR), as BSP method. The results showed that 3 (sites 3, 4 and 9) out of 10 CpG sites have strikingly methylation changes during the re-organization phase compared to the regeneration phase (from 2 hours to 168 hours, P=0.002, 0.048 and 0.018, respectively). Our results showed that methylation modification of CpGs in the Egf promoter region could be restored to the status before PH operation and changes of methylation didn’t affect Egf mRNA expression during the re-organization phase.https://www.celljournal.org/article_250319_f4a9c923abdc0ca0247321dd29ed19dc.pdfRoyan Institute, Iranian Academic Center for Education Culture and Research (ACECR)Cell Journal (Yakhteh)2228-580617320151001Transcription Profiles of Marker Genes Predict The Transdifferentiation Relationship between Eight Types of Liver Cell during Rat Liver Regeneration58258225032010.22074/cellj.2015.21ENXiaoguang ChenAnimal Science and Technology School, Henan University of Science and Technology, Luoyang, ChinaCunshuan XuKey Laboratory for Cell Differentiation Regulation, Henan Normal University, East of Construction Road,
