Adiponectin, as one of the most abundant adipokines, has insulin sensitivity, anti-inflammatory and anti-atherogenic properties. Disturbed adiponectin actions through its receptor, (AdipoR1 and AdipoR2) may be involved in atherosclerosis development. Some adiponectin effects are mediated by AMPK and PPAR-α signaling. AdipoRon is an orally active synthetic molecule which can bind to AdipoR1, Adipo R2 and activate them. AdipoRon can activate AdipoR1-AMPK- PGC-1α pathway and AdipoR2-PPAR-α pathway. Some studies indicated insulin sensitivity, anti-apoptotic and anti-oxidative effect of AdipoRon. We hypothesize that AdipoRon has anti atherosclerotic effect and may suppress atherosclerosis processes. With confirmation the benefit role of AdipoRon on atherosclerosis, it may be used in patients at risk of atherosclerotic development.Mashhad University of Medical SciencesIranian Journal of Basic Medical Sciences2008-386620220170201Toxicology effects of saffron and its constituents: a review110121823010.22038/ijbms.2017.8230ENHasan Badie BostanDepartment of Pharmacodynamics and Toxicology, School of Pharmacy, Mashhad University of Medical Sciences, Mashhad, IranSoghra MehriDepartment of Pharmacodynamics and Toxicology, School of Pharmacy, Mashhad University of Medical Sciences, Mashhad, IranPharmaceutical Research Center, Mashhad University of Medical Sciences, Mashhad, IranNeurocognitive Research Center, Mashhad University of Medical Sciences, Mashhad, IranHossein HosseinzadehDepartment of Pharmacodynamics and Toxicology, School of Pharmacy, Mashhad University of Medical Sciences, Mashhad, IranPharmaceutical Research Center, Mashhad University of Medical Sciences, Mashhad, IranJournal Article20170131Saffron (<em>Crocus sativus</em> L.) has been considered as a medicinal plant since ancient times and also widely used as food additive for its color, taste and odor.

Therefore, designing and producing a more effective vaccine against TB seems urgently. In this study, immunogenicity of a fusion protein which consisting or comprising CFP-10 from Mycobacterium tuberculosis and the Fc-domain of mouse IgG2a was evaluated as a novel subunit vaccine candidate against TB.<br /> <strong><em>Materials and Methods: </em></strong>The genetic constructs were cloned in pPICZαA expression vector and recombinant vectors (pPICZαA-CFP-10: Fcγ2a and pPICZαA-CFP-10:His) were transformed into <em>Pichia pastoris</em>. To evaluate the expression of recombinant proteins, SDS-PAGE and immunoblotting were used. The immunogenicity of recombinant proteins, with and without BCG were assessed in BALB/c mice and specific cytokines against recombinant proteins (IFN-γ, IL-12, IL-4, IL-17 and TGF-β) were evaluated.<br /> <strong><em>Results:</em></strong> The levels of IFN-γ and IL-12 in mice that received recombinant proteins was higher than the control groups (BCG and PBS). Thus, both recombinant proteins (CFP-10:Fcγ2a and CFP-10:His) could excite good response in Th1-cells. The Fc-tagged protein had a stronger Th1 response with low levels of IL-4, as compared to CFP-10:His. However, the highest level of Th1 response was observed in groups that were vaccinated with BCG (prime) and then received recombinant protein CFP-10: Fcγ2a (booster).<br /> <strong><em>Conclusion:</em></strong> The results demonstrated that binding mice Fc-domain to CFP-10 protein can increase the immunogenicity of the subunit vaccine. Further studies, might be able to design and produce a new generation of subunit vaccines based on the Fc-fused immunogen.Mashhad University of Medical SciencesIranian Journal of Basic Medical Sciences2008-386620220170201Protective role of licochalcone B against ethanol-induced hepatotoxicity through regulation of Erk signaling131137823510.22038/ijbms.2017.8235ENXiao-peng GaoDepartment of General Surgery, Xi’an Central Hospital, The Affiliated Xi'an Central Hospital of Xi'an Jiaotong University College of Medicine, Xi'an 710003,P.R.ChinaDong-wei QianDepartment of Operation Room, Xi’an Central Hospital, The affiliated Xi'an central hospital of Xi'an Jiaotong university College of Medicine, Xi'an 710003,P.R.ChinaZhen XieDepartment Two of Neurology, Shaanxi Provincial People’s Hospital, Xi’an, ChinaHao HuiDepartment Two of Neurology, Shaanxi Provincial People’s Hospital, Xi’an, ChinaJournal Article20170131<strong><em>Objective(s)</em></strong>: Oxidative stress has been established as a key cause of alcohol-induced hepatotoxicity. Licochalcone B, an extract of licorice root, has shown antioxidative properties. This study was to investigate the effects and mechanisms of licochalcone B in ethanol-induced hepatic injury in an <em>in vitro</em> study.<br /> <strong><em>Materials and Methods:</em></strong> An <em>in vitro</em> model of Ethanol-induced cytotoxicity in BRL cells was used in this study. Cell injury was assessed using WST-1 assay and lactate dehydrogenase, alanine transaminase, and aspartate aminotransferase release assay. Cell apoptosis were quantified by flow cytometric analysis. The intracellular oxidative level was evaluated by reactive oxidative species, malondialdehyde and glutathione detection. Furthermore, the expression level of Erk, p-Erk, Nrf-2 were assessed using Western blot.<br /> <strong><em>Results:</em></strong> Treatment with ethanol induced marked cell injury and cell apoptosis in BRL cells. Licochalcone B significantly attenuated ethanol-induced cell injury, and inhibited cell apoptosis. Furthermore, licochalcone B significantly inhibited ethanol-induced intracellular oxidative level, upregulated the expression of p-Erk, and promoted nuclear localization of Nrf2. Additionally, this hepatoprotective role was significantly abolished by inhibition of Erk signaling. However, no apparent effects of Erk inhibition were observed on ethanol-induced hepatotoxicity.<br /> <strong><em>Conclusion:</em></strong> This study demonstrates that licochalcone B protects hepatocyte from alcohol-induced cell injury, and this hepatoprotective role might be attributable to apoptosis reduction, inhibition of oxidative stress, and upregulation of Erk–Nrf2. Therefore, licochalcone B might possess potential as a novel therapeutic drug candidate for alcohol-related liver disorders.Mashhad University of Medical SciencesIranian Journal of Basic Medical Sciences2008-386620220170201Exploring the effect of intravenous lipid emulsion in acute methamphetamine toxicity138144823610.22038/ijbms.2017.8236ENAmeneh GhadiriDepartment of Toxicology, Faculty of Pharmacy, Islamic Azad University, Shahreza Branch, Shahreza, IranLeila EtemadPharmaceutical Research Center, Mashhad University of Medical Sciences, Mashhad, Iran0000-0002-2800-9395Mohammad MoshiriLegal Medicine Research Center, Legal Medicine Organization, Tehran, IranSeyed Adel MoallemDepartment of Pharmacodynamics and Toxicology, School of Pharmacy, Mashhad University of Medical Sciences, Mashhad, IranAmir Hossein JafarianDepartment of Pathology, Ghaem Hospital, Mashhad University of Medical Sciences, Mashhad, IranFarzin HadizadehBiotechnology Research Center, Mashhad University of Medical Sciences, Mashhad, IranMahmoud SeifiBiotechnology Research Center, School of Pharmacy, Mashhad University of Medical Sciences, Mashhad, IranJournal Article20170131<strong><em>Objective(s):</em></strong> The increasing use of methamphetamine (METH) in the last decades has made it the second most abused drug. Advancs in the area of intravenous lipid emulsion (ILE) have led to its potential application in the treatment of poisoning. The present study aims to investigate the potential role of ILE as an antidote for acute METH poisoning.<br /> <strong><em>Materials and Methods:</em></strong> Two groups of six male rats were treated by METH (45 mg/kg), intraperitoneally. Five to seven min later, they received an infusion of 18.6 ml/kg ILE 20% through the tail vein or normal saline (NS). Locomotor and behavioral activity was assessed at different time after METH administration. Body temperature and survival rates were also evaluated. Brain and internal organs were then removed for histological examination and TUNEL assay.<br /> <strong><em>Results</em></strong><strong>:</strong> ILE therapy for METH poisoning in rats could prevent rats mortalities and returned the METH-induced hyperthermia to normal rates (<em>P</em><0.05). ILE reduced freezing and stereotyped behaviors and increased rearing responses (<em>P</em><0.05). Locomotor activity also returned to control levels especially during the last hours of the experiment. ILE administration decreased the prevalence of pulmonary emphysema in the lungs (<em>P</em>P<0.01) and percentages of TUNEL positive cells in the brain (<em>P</em><0.05), in comparison with the control group.<br /> <strong><em>Conclusion:</em></strong> ILE could reduce the severity of METH- induced toxicity as well as mortality rate in the animals. Intravenous infusion of lipid emulsion may save the life of patients with acute METH intoxication who do not respond to standard initial therapy.Mashhad University of Medical SciencesIranian Journal of Basic Medical Sciences2008-386620220170201Effect of sodium hydrosulfide on mRNA expression of prostaglandin E2 receptors in response to mucosal acidification and distention-induced gastric acid secretion in rats145149823710.22038/ijbms.2017.8237ENSeyyed Ali MardPhysiology Research Center and Research Center for Infectious Diseases of Digestive System, Department of Physiology, School of Medicine, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, IranSimin MahiniPhysiology Research Center and Research Center for Infectious Diseases of Digestive System, Department of Physiology, School of Medicine, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, IranMahin DianatPhysiology Research Center and Department. of Physiology, School of Medicine, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, IranYaghoob FarboodPhysiology Research Center and Department. of Physiology, School of Medicine, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, IranJournal Article20170131<strong><em>Objective(s)</em></strong>: Prostaglandins have been shown to mediate the gastro-protective effect of sodium hydrosulfide (NaHS) but effect of NaHS on mRNA expression of prostaglandin E<sub>2 </sub>receptors (EP1, 3-4; EPs) has not been investigated. Therefore, this study designed to evaluate the effect of NaHS on mRNA expression of EPs receptors in response to mucosal acidification and distention-induced gastric acid secretion in rats.<br /> <strong><em>Materials and Methods: </em></strong>Fasted rats were randomly assigned into 4 groups (n=6/group). They were control, and NaHS-treated groups. To evaluate the effect of NaHS on mucosal mRNA expression of EPs receptors, the gastric mucosa exposed to stimulated gastric acid output and mucosal acidification. The pylorus sphincter catheterized for instillation of isotonic neutral saline or acidic solution. Ninety min after beginning the experiments, animals sacrificed and the gastric mucosa collected to determine the pH, mucus secretion and to quantify the mRNA expression of EPs receptors by quantitative real-time PCR.<br /> <strong><em>Results: </em></strong>present results showed that a) NaHS increased the mucus secretion, mRNA expression of EP3 and EP4 receptors in response to distention-induced expression; b) The mRNA expression of EP1 receptors increased while EP4 mRNA receptors decreased in response to mucosal acidification in NaHS-pretreated rats; and c) NaHS increased pH of gastric contents both in response to distention-induced gastric acid secretion and mucosal acidification.<br /> <strong><em>Conclusion:</em></strong> NaHS behaves in a different manner. It effectively only increased the pH of gastric contents to reinforce the gastric mucosa against a highly acidic solution but modulated both acid and mucus secretion when the rate of acid increase in the stomach was slower.Mashhad University of Medical SciencesIranian Journal of Basic Medical Sciences2008-386620220170201Gestational diabetes leads to down-regulation of CDK4-pRB-E2F1 pathway genes in pancreatic islets of rat offspring150154824010.22038/ijbms.2017.8240ENZahra NazariDepartment of Animal Sciences, Faculty of Biological Sciences, Kharazmi University, Tehran, IranMohammad NabiuniDepartment of Cell and Molecular Biology, Faculty of Biological Sciences, Kharazmi University, Tehran, IranMohsen SaeidiStem Cell Research Center, Faculty of Medicine, Golestan University of Medical Sciences, Gorgan, IranMohammad Jafar GolalipourGorgan Congenital Malformations Research Center, Depatment of Anatomical Sciences, Golestan University of Medical Sciences, Gorgan, Iran0000-0002-0646-7096Journal Article20170131<strong><em>Objective(s):</em></strong> The link between a hyperglycemic intrauterine environment and the development of diabetes later in life has been observed in offspring exposed to gestational diabetes mellitus (GDM), but the underlying mechanisms for this phenomenon are still not clear. Reduced β-cells mass is a determinant in the development of diabetes (type 1 and type 2 diabetes). Some recent studies have provided evidence that the CDK4-pRB-E2F1 regulatory pathway is involved in β-cells proliferation. Therefore, we postulated that GDM exposure impacts the offspring’s β-cells by disruption in the CDK4-pRB-E2F1 pathway.<br /> <strong><em>Materials and Methods: </em></strong>Adult Wistar rats were randomly allocated in control and diabetic group. The experimental group received 40 mg/kg/body weight of streptozotocin (STZ) on day zero of gestation. After delivery, diabetic offspring of GDM mothers and control dams at the age of 15 week were randomly scarified and pancreases were harvested. Langerhans islets of diabetic and control groups were digested by collagenase digestion technique. After RNA extraction, we investigated the expressions of the kir 6.2 and CDK4-pRB-E2F1 pathway genes by quantitative real-time PCR.<br /> <strong><em>Results:</em></strong> GDM reduced the expression of CDK4-pRB-E2F1 pathway genes in Langerhans islets cells of offspring. CDK4, pRB and E2F1 pathway genes were downregulated in diabetic islets by 51%, 35% and 84%, respectively. Also, the expression of Kir 6.2 was significantly decreased in diabetic islets by 88%.<br /> <strong><em>Conclusion:</em></strong> We suggest that the effect of gestational diabetes on offspring’s β-cells may be primarily caused by the suppression of CDK4-pRB-E2F1 pathway.Mashhad University of Medical SciencesIranian Journal of Basic Medical Sciences2008-386620220170201The effect of hydro-ethanolic extract of Curcuma longa rhizome and curcumin on total and differential WBC and serum oxidant, antioxidant biomarkers in rat model of asthma155165824110.22038/ijbms.2017.8241ENFarzaneh ShakeriNeurogeneeic Inflammation Research Center, Mashhad University of Medical Sciences, Mashhad, IranDepartment of Physiology, School of Medicine, Mashhad University of Medical Sciences, Mashhad, IranMohammad SoukhtanlooDepartment of Biochemistry, School of Medicine, Mashhad University of Medical Sciences, Mashhad, IranMohammad Hossein BoskabadyNeurogeneeic Inflammation Research Center, Mashhad University of Medical Sciences, Mashhad, IranDepartment of Physiology, School of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran0000-0001-5736-9755Journal Article20170131<strong><em>Objective(s)</em></strong>: The effects of <em>Curcuma longa</em> (<em>C. longa</em>) and curcumin on total and differential WBC count and oxidant, antioxidant biomarkers, in rat model of asthma were evaluated.<br /> <strong><em>Materials and Methods: </em></strong>Total and differential WBC count in the blood, NO<sub>2</sub>, NO<sub>3</sub>, MDA, SOD, CAT and thiol levels in serum were examined in control, asthma, Asthmatic rats treated with <em>C. longa</em> (0.75, 1.50, and 3.00 mg/ml), curcumin (0.15, 0.30, and 0.60 mg/ml), and dexamethasone (1.25 μg/ml) rats.<br /> <strong><em>Results:</em></strong> Total and most differential WBC count, NO<sub>2</sub>, NO<sub>3</sub> and MDA were increased but lymphocytes, SOD, CAT and thiol were decreased in asthmatic animals compared to controls (<em>P</em><0.001).

Here we investigated the effects of simulated microgravity on neural differentiation of human adipose-derived stem cells (ADSCs).
<strong><em>Materials and Methods</em><em>:</em></strong>We have used a fast rotating clinostat (clinorotation) to simulate microgravity condition. Real-time PCR and flow cytometry analysis were used to evaluate the regulation of neurotrophins, their receptors, and neural markers by simulated microgravity and their impact on neural differentiation of cells.
<strong><em>Results</em>:</strong> Our data revealed that simulation microgravity up-regulated the expression of <em>MAP-2</em>, <em>BDNF</em>, <em>TrkB</em>, <em>NT-3,</em> and <em>TrkC</em> both before and after neural differentiation. Also, the neural cells derived from ADSCs in microgravity condition expressed more <em>MAP-2</em>, <em>GFAP,</em> and synaptophysin protein in comparison to the 1G control.
<strong><em>Conclusion:</em></strong> We showed that simulated microgravity can enhance the differentiation of mesenchymal stem cells into neurons. Our findings provide a new strategy for differentiation of ADSCs to neural-like cells and probably other cell lineages. Meanwhile, microgravity simulation had no adverse effects on the viability of the cells and could be used as a new environment to successfully manipulate cells.Mashhad University of Medical SciencesIranian Journal of Basic Medical Sciences2008-386620220170201The miR-383-LDHA axis regulates cell proliferation, invasion and glycolysis in hepatocellular cancer187192824610.22038/ijbms.2017.8246ENZhixiong FangDepartment of Infectious Disease, XiangTan City Central Hospital, XiangTan, People's Republic of ChinaLangqiu HeDepartment of Infectious Disease, XiangTan City Central Hospital, XiangTan, People's Republic of ChinaHui JiaDepartment of Infectious Disease, XiangTan City Central Hospital, XiangTan, People's Republic of ChinaQiusheng HuangDepartment of Infectious Disease, XiangTan City Central Hospital, XiangTan, People's Republic of ChinaDan ChenEdong Healthcare City Hospital of Traditional Chinese Medicine, Inefections Disease Hospital, Huangshi, People's Republic of ChinaZhiwei ZhangCancer Research Institute, University of South China, Key Laboratory of Cancer Cellular and Molecular Pathology of Hunan Provincial University, Hengyang, People's Republic of ChinaJournal Article20170131<strong><em>Objective(s)</em></strong>: To explore the correlation between expression patterns and functions of miR-383 and LDHA in hepatocellular cancer (HCC).<br /> <strong><em>Materials and Methods: </em></strong>We detected the expression of miR-383 and LDHA in 30 HCC tissues and their matched adjacent normal tissues using qRT-PCR. Then we performed MTT assay, foci formation assay, transwell migration assay, glucose uptake assay and lactate production assay to explore the function of miR-383 in cell proliferation, invasion and glycolysis in HCC cell lines. Luciferase reporter assay was used to explore whether LDHA was a target gene of miR-383. Western blot and qRT-PCR were used to further confirm LDHA was targeted by miR-383. Then the above functional experiments were repeated to see whether the function of LDHA could be inhibited by miR-383.<br /> <strong><em>Results:</em></strong> The results of qRT-PCR showed that miR-383 was down-regulated in HCC tissues compared with their matched adjacent normal tissues. Functional experiments showed that overexpression of miR-383 significantly suppressed cell proliferation, invasion and glycolysis. Luciferase reporter assay showed LDHA was a target gene of miR-383 and expression of LDHA was inversely correlated with that of miR-383 in HCC. Besides, increased cell proliferation, invasion and glycolysis triggered by LDHA could be inhibited by overexpression of miR-383 in HCC cell lines.<br /> <strong><em>Conclusion:</em></strong> Our study proved that miR-383 is down-regulated in HCC and acts as a tumor suppressor through targeting LDHA. Targeting the miR-383-LDHA axis might be a promising strategy in HCC treatment.Mashhad University of Medical SciencesIranian Journal of Basic Medical Sciences2008-386620220170201In vitro lymphoproliferative response and cytokine production in mice with experimental disseminated candidiasis193198824810.22038/ijbms.2017.8248ENAli Reza KhosraviMycology Research Center, Faculty of Veterinary Medicine, University of Tehran, Tehran, IranHojjatollah ShokriDepartment of Pathobiology, Faculty of Veterinary Medicine, Amol University of Special Modern Technologies, Amol, IranShahin EshghiDepartment of Food Sciences, Qazvin, Iranian Veterinary OrganizationJournal Article20170131<strong><em>Objective(s)</em></strong>: Systemic candidiasis is an infection of <em>Candida albicans</em> (<em>C. albicans</em>) causing disseminated disease and sepsis, invariably when host defenses are compromised.

Stimulation with PWM and Con A showed no differences in IL-4 production between infected mice and controls.<br /> <strong><em>Conclusion:</em></strong> These findings demonstrated a significant increase in both cell proliferation and IFN-γ secretion in supernatants of PWM and Con A- stimulated splenocyte cultures obtained from mice with disseminated candidiasis.Mashhad University of Medical SciencesIranian Journal of Basic Medical Sciences2008-386620220170201Nicotine-induced damages in testicular tissue of rats; evidences for bcl-2, p53 and caspase-3 expression199208824910.22038/ijbms.2017.8249ENMaryam MosadeghDepartment of Comparative Histology & Embryology, Faculty of Veterinary Medicine, Urmia University, Urmia, IranShapour HasanzadehDepartment of Comparative Histology & Embryology, Faculty of Veterinary Medicine, Urmia University, Urmia, IranMazdak RaziDepartment of Comparative Histology & Embryology, Faculty of Veterinary Medicine, Urmia University, Urmia, Iran0000-0002-4309-4831Journal Article20170131<strong><em>Objective(s)</em></strong>: Present study was performed in order to uncover new aspects for nicotine-induced damages on spermatogenesis cell lineage.<br /> <strong><em>Materials and Methods: </em></strong>For this purpose, 36 mature male Wistar rats were divided into three groups as; control-sham (0.2 ml, saline normal, IP), low dose (0.2 mg/kg BW<sup>-1</sup>, IP) nicotine-received and high dose (0.4 mg/kg BW<sup>-1</sup>, IP) nicotine-received groups. Following 7 weeks, the expression of bcl-2, p53 and caspase-3 at mRNA and protein levels were investigated by using reverse-transcriptase PCR (RT-PCR) and immunohistochemical (IHC) analyses, respectively. Moreover, the serum level of FSH, LH and testosterone were evaluated. Finally, the mRNA damage was analyzed by using special fluorescent staining.<br /> <strong><em>Results:</em></strong> Nicotine, at both dose levels, decreased tubular differentiation, spermiogenesis and repopulation indices and enhanced cellular depletion. Animals in nicotine-received groups exhibited a significant (<em>P</em><0.05) reduction at mRNA and protein levels of bcl-2. More analyses revealed a remarkable (<em>P</em><0.05) enhancement in expression of p53 and caspase-3 in comparison to control-sham animals. Finally, nicotine resulted in a significant (<em>P</em><0.05) reduction in serum level of testosterone and elevated mRNA damage.<br /> <strong><em>Conclusion:</em></strong> Our data showed that, nicotine by suppressing the testosterone biosynthesis, reducing mRNA and protein levels of bcl-2 and up regulating the p53 and caspase-3 mRNA and protein levels adversely affects the spermatogenesis and results in cellular depletion.Mashhad University of Medical SciencesIranian Journal of Basic Medical Sciences2008-386620220170201Up-regulation of TLR2 and TLR4 in high mobility group Box1-stimulated macrophages in pulpitis patients209215825010.22038/ijbms.2017.8250ENJavad MahmoudiNeurosciences Research Center, Tabriz University of Medical Science, Tabriz, IranBabak SabermaroufNeurosciences Research Center, Tabriz University of Medical Science, Tabriz, IranBehzad BaradaranImmunology Research Center, Tabriz University of Medical Science, Tabriz, IranLeila Sadat-HatamnezhadImmunology Research Center, Tabriz University of Medical Science, Tabriz, IranSiamak Sandoghchian ShotorbaniDepartment of Immunology, Tabriz Branch, Islamic Azad University, Tabriz, IranJournal Article20170131<strong><em>Objective(s)</em></strong>: High Mobility Group Box1 (HMGB1) is a nonhistone, DNA-binding protein that serves a crucial role in regulating gene transcription and is involved in a variety of proinflammatory, extracellular activities. The aim of this study was to explore whether HMGB1 stimulation can up-regulate the expression of Toll-like Receptor 2 (TLR2) and Toll-like Receptor 4 (TLR4) on macrophages from pulpitis and to clarify the subsequent events involving Th17 cells and Th17 cell-associated cytokine changes.<br /> <strong><em>Materials and Methods: </em></strong>Having prepared dental pulp tissues of pulpitis and healthy controls, macrophage were isolated and cultured. Macrophages were thereafter stimulated by HMGB1 time course. RT-QPCR, flowcytometer, immunofluorescence, Western blotting, and ELISA techniques were used in the present research.<br /> <strong><em>Results:</em></strong> Our results showed that the expression of TLR2 and TLR4 on macrophages stimulated with HMGB1 increased in pulpitis compared with controls (macrophages without HMGB1 stimulation) with a statistical significance (<em>P<</em>0.001). In addition, the levels of IL-17, IL-23, and IL-6 in supernatants from cultured macrophages stimulated with HMGB1 from pulpitis increased, and NF-kB, the downstream target of TLR2 and TLR4, also showed a marked elevation after macrophages’ stimulation by HMGB1.<br /> <strong><em>Conclusion:</em></strong> The evidence from the present study suggests that the enhanced TLR2 and TLR4 pathways and Th17 cell polarization may be due to HMGB1 stimulation in pulpitis.Mashhad University of Medical SciencesIranian Journal of Basic Medical Sciences2008-386620220170201Gestational diabetes influences retinal Muller cells in rat's offspring216221825110.22038/ijbms.2017.8251ENAkramsadat TabasiDepartment of Anatomical Sciences, Golestan University of Medical Sciences, Gorgan, IranSoraya GhafariGorgan Congenital Malformations Research Center, Department of Anatomical Sciences, Golestan University of Medical Sciences, Gorgan, IranMehdi MehdizadehDepartment of Anatomical Sciences, School of Medicine, Iran University of Medical Sciences, Tehran, IranMajid Asadi ShekariNeuroscience Research Center, Neuropharmacology Institute.

The expression of Glial fibrillary acidic protein (GFAP) in the Muller cells was used as a cellular marker for retinal damage. This study was done to evaluate the effect of gestational diabetes on retinal Muller cells in rat's offspring.<br /> <strong><em>Materials and Methods: </em></strong>In this experimental study, 12 Wistar rat dams were randomly allocated in control and diabetic groups. Gestational diabetes was induced by 40 mg/kg/body weight of streptozotocin at the first day of gestation, intraperitoneally. Dams in control group received an equivalent volume normal saline. Eye of six offspring of each group were removed at postnatal day 28 (P28). The histopathological changes in retina were examined through H&E staining and ultrastructure transmission electron microscopy (TEM). The expression of GFAP was examined using Immunohisto-chemical staining of GFAP in Muller cells. Photographs of retina were taken using Olympus BX51 microscope and a digital camera DP12 and EM LEO906; Zeiss, Germany.<br /> <strong><em>Results:</em></strong> In the control rat's offspring, GFAP expression was not significant in Muller cells. According to the optical microscope images, GFAP expression was observed in the processes of the Muller cell in the inner plexiform layer of retina in offspring of diabetic mothers. In TEM technique, nuclear fragmentation and apoptotic bodies were observed in Muller cell of diabetic offspring.<br /> <strong><em>Conclusion:</em></strong> This study showed that the uncontrolled gestational diabetes can increase GFAP expression in Muller cells and retinal thickness of retinal layer in rat offspring's, therefore uncontrolled gestational can damage the Muller cells.
