Hepcidin Mrna

Diabetes is a disease with an inflammatory component that courses with an anemic state. Vanadium (V) is an antidiabetic agent that acts by stimulating insulin signaling. Hepcidin blocks the intestinal absorption of iron and the release of iron from its deposits. We aim to investigate the effect of V on hepcidin mRNA expression and its consequences on the hematological parameters in streptozotocin-induced diabetic Wistar rats. Control healthy rats, diabetic rats, and diabetic rats treated with 1 mgV/day were examined for five weeks. The mineral levels were measured in diet and serum samples. Hepcidin expression was quantified in liver samples. Inflammatory and hematological parameters were determined in serum or whole blood samples. The inflammatory status was higher in diabetic than in control rats, whereas the hematological parameters were lower in the diabetic rats than in the control rats. Hepcidin mRNA expression was significantly lower in the V-treated diabetic rats than in control and untreated diabetic rats. The inflammatory status remained at a similar level as the untreated diabetic group. However, the hematological profile improved after the V-treatment, reaching similar levels to those found in the control group. Serum iron level was higher in V-treated than in untreated diabetic rats. We conclude that V reduces gene expression of hepcidin in diabetic rats, improving the anemic state caused by diabetes.

Background: An in-depth study of dismetabolic mechanisms in the genesis of pre-eclampsia (PE) has been updated because pregnancy is considered as a natural model of metabolic syndrome (MS), as well as the metabolic disorders are important in development of essential hypertension.Aims: to reveal clinical and laboratory parallels in pregnancy complicated by PE without MS and pregnancy proceeding on the background of MS to assess the role of metabolic disturbances in the development of PE.Materials and methods: 82 women with MS were examined in the dynamics of pregnancy and were divided into 2 groups depending on the implementation of PE: group I consisted of 50 women with PE on the background of MS, group II 32 women with MS without PE. We formed group III consisting of 44 pregnant women with PE without accompanying diseases to assess the pathogenetic value of metabolic disorders in the development of PE. The IV (control) group consisted of 30 healthy women with physiological pregnancy. Metabolic, hematological parameters, hormones, markers of the proinflammatory state, endothelial hemostasiological dysfunction, decidualization and placental angiogenesis, accumulation dynamics and distribution loci of adipose tissue were determined in all pregnant women.Results: In the groups of pregnant women with PE, changes similar to MS were revealed: pronounced diabetic and atherogenic disorders with the development of pathological insulin resistance, hyperinsulinemia and leptinemia, endothelial-platelet link hyperactivation, thrombotic and inflammatory status, visceral type of fat deposition, hyperuricemia, hypersympathicotonia. It is proved that in the hierarchy of mechanisms of PE formation, placental dysfunction is a secondary alteration factor, which additionally potentiates the insulin resistance increase and the effects of structural and functional destabilization of the vascular endothelium.Conclusions: The direction of metabolic changes during pregnancy, the common development of PE and MS indicate the important role of dismetabolic mechanisms in the formation of PE.

Background: Diabetes mellitus deeply changes the genes expression of integrin (Itg) subunits in several cells and tissues such as monocytes, arterial endothelium, kidney glomerular cells, retina. Furthermore, hyperglycemia could impress and reduce the rate of successful assisted as well as non-assisted pregnancy. Endometrium undergoes thorough changes in normal menstrual cycle and the question is: What happens in the endometrium under diabetic condition? Objective: The aim of the current study was to investigate the endometrial gene expression of α3, α4, αv, Itg β1 and β3 subunits in diabetic rat models at the time of embryo implantation. Materials and Methods: Twenty-eight rats were randomly divided into 4 groups: control group, diabetic group, pioglitazone-treated group, and metformin-treated group. Real-time PCR was performed to determine changes in the expression of Itg α3, α4, αv, β1, and β3 genes in rat’s endometrium. Results: The expression of all Itg subunits increased significantly in diabetic rats’ endometrium compared with control group. Treatment with pioglitazone significantly reduced the level of Itg subunits gene expression compared with diabetic rats. While metformin had a different effect on α3 and α4 and elevated these two subunits gene expression. Conclusion: Diabetes mellitus significantly increased the expression of studied Itg subunits, therefore untreated diabetes could be potentially assumed as one of the preliminary elements in embryo implantation failure.

Background: Myeloperoxidase (MPO) is involved in the initiation, progression, and complications of atherosclerosis in diabetic patients. Objectives: In the current study, the impact of alpha-lipoic acid (LA), a natural antioxidant and a cofactor in the enzyme complexes on MPO, catalase (CAT) and glutathione peroxidase (GPx) activity, glutathione (GSH) and malondialdehyde (MDA) level, histopathology of kidney and expression of antioxidant enzymes, superoxide dismutase (SOD), GPx and CAT which are involved in the detoxification of reactive oxygen species (ROS), was evaluated in alloxan-induced diabetic rats. Materials and Methods: In this study, 30 male Rattus norvegicus rats randomly divided into three groups; control (C), non-treated diabetic (NTD), and LA-treated diabetics (LATD) was induced by alloxan monohydrate (100mg/kg; subcutaneous [SC]). Then treatment was performed with alphaLA (100 mg/kg intraperitoneal (i.p) daily to 6 weeks). Blood sample of animals collected to measure levels of MPO, CAT and GPx activity GSH and MDA. Kidney paraffin sections were prepared to estimate histological studies and to measure quantitative gene expression SOD, GPX and CAT in kidney. Results: Induction of diabetes led to a significant increase in MPO and MDA, reduced GSH level and GPx and CAT activities (P < 0.05). However, treatment with alpha-LA led to a significant elevation in GPx, CAT and GSH levels with a reduction in MPO activities and MDA levels (P < 0.05). Furthermore, the real-time reverse transcriptase-polymerase chain reaction (RT-PCR) analysis results showed increased expressions of GPx, CAT and SOD enzyme in the treatment group compared with the diabetic control group. Histopathological lesions such as increased glomerular volume and lymphocyte infiltration were attenuated in the alpha-LA treated group. Conclusions: Our findings indicated that alpha-LA supplementation is effective in preventing complications induced by oxidative stress and atherosclerosis in diabetic rats.

Objectives: To discover the role of altered gene expression regulation in Brugada Syndrome (BrS) and to find biomarkers for BrS diagnosis. Methods: Twenty-five control patients (Control), 25 BrS patients without SCN5A mutation (SCN5A(-)) and 20 BrS patients with SCN5A mutation (SCN5A(+)) were included in this study. Specified gene expression of white blood cells (WBC) were measured by RT-qPCR using TaqMan® Gene Expression assay. Results: MEF2C and MESP1 are the two major cardiac specific transcription factors expressed in WBC. The mRNA expression levels of SCN5A, MEF2C and HuR, one of mRNA stabilizers, were decreased in the SCN5A (+) group (P=0.047, 0.02, 0.000 vs. control group, respectively). The mRNA expression of MESP1 in WBCs was significantly lower in both SCN5A(-) (P=0.012 vs. control) and SCN5A(+) (P=0.000 vs. control) groups. There was no difference between the two BrS groups in MESP1 expression (P=0.215). The area under the Receiver Operating Characteristics (ROC) analysis curve for prediction of BrS using MESP1 levels was 0.775 (95% CI 0.668, 0.882, asymptotic Sig.=0.000). At the optimal cutoff, the corresponding maximum sensitivity and specificity were 0.62 (95% CI: 0.47, 0.76) and 0.88 (0.69, 0.97), respectively. The diagnostic odds ratio (DOR) of MESP1 for BrS diagnosis was 11.96 (95% CI: 5.79, 24.73). The assessment of the mRNA levels in blood SCN5A, MEF2C and HuR were useful for predicting BrS patients with an SCN5A mutation. The area under the ROC analysis curve for prediction of BrS with an SCN5A mutation using SCN5A, MEF2C and HuR mRNA levels in WBCs was 0.847 (95% CI 0.752, 0.942, asymptotic Sig.=0.000), 0.685 (95% CI 0.542, 0.828, asymptotic Sig.=0.016) and 0.777 (95% CI 0.652, 0.902, asymptotic Sig.=0.000), respectively. At the optimal cutoff, the DOR of SCN5A, MEF2C and HuR for SCN5A(+) BrS diagnosis was 17.5 (95% CI: 8.06, 37.86), 4.9 (95% CI: 2.61, 9.17) and 23.5 (95% CI: 9.39, 58.80), respectively. Conclusions: Our results suggest that assessment of circulating MESP1 may be used as a biomarker for BrS diagnosis while decreased SCN5A, MEF2C and HuR mRNA in WBCs is associated with BrS patients with an SCN5A mutation. Our results also suggest that decreased expression of SCN5A, MEF2C, MESP1, and HuR may be pathophysiologically related to BrS.

Abstract Background Apelin, an adipokine peptide and its receptor has recently emerged as a key signaling pathway in maintaining cardiac performance at chronic pressure loads. Apelin has been linked to ventricular dysfunction and therefore maybe of pathophysiologic relevance as a candidate biomarker in HF patients. Purpose This study aims to investigate Apelin-13 gene expression and level, and Apelin receptor (APJ) level in a rat model of heart failure induced by chronic systemic hypoxia and their correlation to BNP-45 gene expression and level, the current gold standard biomarker for heart failure, and to cardiac histopathologic changes. The effect of chronic systemic hypoxia on cardiac hypertrophy, remodeling and heart failure parameters is also of interest. Methods Twenty-eight male Sprague-Dawley rats (8–12 weeks of age) were placed in special hypoxic chambers divided into 7 groups – a control group provided with normoxia (atmospheric O2 levels) and 6 exposure groups exposed to hypoxia (8% O2) for 6 hours, 1, 3, 5, 7 and 14 days respectively prior to measurement. Changes in the expression of Apelin and BNP-45 were measured using quantitative real-time PCR, whereas changes in Apelin-13, APJ and BNP-45 levels were measured using ELISA. Histopathology staining using Hematoxylin and Eosin was performed on cardiac tissues post-termination. Results Compared to control, BNP-45 mRNA expression in the hypoxic heart was only significantly different in day 14, whereas, Apelin mRNA expression had showed significantly higher values starting from day 7 onward. This is in line with the evidence of cardiac hypertrophy based on histopathologic examination present from day 7 onwards. BNP-45 and Apelin-13 levels were significantly higher compared to control from day 5 onwards with a peak on day 7. Although significantly higher than control, Apelin-13 and BNP-45 level decreases in day 14 as compared to day 7. Mean APJ levels showed a similar profile with Apelin-13 and BNP-45 levels with a peak in day 7 (4.619 ng/mL). The cardiac Apelin-13 level shows strong significant correlation with BNP-45 levels (r 0.823, p-value 0.0001). There was also a strong significant correlation between APJ receptor levels with Apelin-13 (r 0.9029, p-value 0.001) and BNP-45 (r 0.9062, p-value 0.0009) levels. Apelin-13, APJ and BNP-45 levels also showed strong significant positive correlation to the duration of hypoxia exposure. Conclusion Chronic (≥5 days) and not acute systemic hypoxia in an experimental rat model leads to increase in Apelin-13, APJ and BNP-45 levels. Apelin-13 and BNP-45 were found to significantly increase from 5 days onwards. Apelin mRNA expression was found to show significant increase earlier compared to BNP-45 mRNA expression. Hence, Apelin may serve as a new candidate biomarker for detection of HF due to oxidative stress compared to BNP-45. Exposure to chronic systemic hypoxia can serve as an easily replicable rat model for heart failure.

This study investigated the effects of polysaccharides fromEnteromorpha prolifera(PEP) on glucose metabolism in a rat model of diabetes mellitus (DM). PEP (0, 150, 300, and 600 mg/kg) was administered intragastrically to rats for four weeks. After treatment, fasting blood glucose (FBG) and insulin (INS) levels were measured, and the insulin sensitivity index (ISI) was calculated. The morphopathological changes in the pancreas were observed. Serum samples were collected to measure the oxidant-antioxidant status. The mRNA expression levels of glucokinase (GCK) and insulin receptor (InsR) in liver tissue and glucose transporter type 4 (GLUT-4) and adiponectin (APN) in adipose tissue were determined. Compared with the model group, the FBG and INS levels were lower, the ISI was higher, and the number of isletβ-cells was significantly increased in all the PEP groups. In the medium- and high-dose PEP groups, MDA levels decreased, and the enzymatic activities of SOD and GSH-Px increased. The mRNA expression of InsR and GCK increased in all the PEP groups; APN mRNA expression increased in the high-dose PEP group, and GLUT-4 mRNA expression increased in adipose tissue. These findings suggest that PEP is a potential therapeutic agent that can be utilized to treat DM.

To explore the effect of Eimeria tenella infection on the cytokines gene expression and IgA production in the spleen of chickens, the morphological characteristics of the spleen were observed through optical and transmission electron microscopy. The IgA production was determined through immunohistochemistry. The mRNA expression levels of splenic cytokines were detected through real-time PCR. Compared to the control group, along with the infection of E. tenella, the splenic lymphocytes exhibited irregular and cracked membranes, mitochondria swelled even vacuolization, the IgA expression in spleen tissue was decreased by 55.57% (p lessthan 0.01). Likewise, the mRNA expression levels of IL-2 and IL-1â decreased by 40% (plessthan 0.01) and 43% p lessthan 0.05), respectively. By contrast, the IL-6, IFN-g and IL-10 levels increased by 158% (p lessthan 0.01), 464% (p lessthan 0.05) and 379% p lessthan 0.01), respectively. These results indicated that the spleen implement an important function in the antagonism of E. tenella, which suggest a new strategy to control coccidiosis by improving the peripheral immunity of chickens.

Transforming growth factor beta (TGFβ) is a family of genes that play a key role in mediating tissue remodeling in various forms of acute and chronic lung disease. In order to assess their role on pulmonary hypertension in broilers, we determined mRNA expression of genes of the TGFβfamily and endothelin 1 in lung samples from 4-week-old chickens raised either under normal or cold temperature conditions. Both in control and cold-treated groups of broilers, endothelin 1 mRNA expression levels in lungs from ascitic chickens were higher than levels from healthy birds (), whereas levels in animals with cardiac failure were intermediate. Conversely, TGFβ2 and TGFβ3 gene expression in lungs were higher in healthy animals than in ascitic animals in both groups (). TGFβ1, TβRI, and TβRII mRNA gene expression among healthy, ascitic, and chickens with cardiac failure showed no differences (). BAMBI mRNA gene expression was lowest in birds with ascites only in the control group as compared with the values from healthy birds ().

Background. Mycosis fungoides (MF) is the most common disease among the cutaneous T-cell lymphomas (85-90%). The accuracy of the diagnosis of MF, which is confirmed only by clinical, histological and immunohistochemical signs, is 50-75%. The aim of the study was to investigate genetic markers (FOXP3, STAT4, IL-12B) for early diagnosis of mycosis fungoides. Material and methods. A study involving 42 patients with MF and plaque parapsoriasis (PP) treated at the Dermatology Department of I.M. Sechenov First Moscow State Medical University and National Medical Hematology Research Сenter, was performed. The analysis of gene expression FOXP3, STAT4, IL-12B was carried out by TaqMan Real time-PCR. The objects of the study were lesional skin samples of patients. A group with MF consisted of 29 patients, a group with PP consisted of 13 patients, a control group included 10 healthy volunteers. Results. The study revealed that the level of STAT4 gene expression showed a significant (9 times) increase in the mRNA expression of STAT4 transcripts in patients with MF (166) compared with patients with PP (17.9; p < 0.05) and 553 times - with healthy volunteers (0.3; p < 0.05). There was also a statistically significant predominance of the level of mRNA expression of STAT4 transcripts in patients with spotted and plaque stages of MF (180; 318) compared with patients with PP (17.9; p < 0.05) and healthy volunteers (0.3; p < 0.05), as well as a sharp decrease in patients with erythrodermic form of MF (7.19). For early diagnosis of MF the level of expression of mRNA transcripts STAT4 is of great importance. Inclusion of STAT4 in the list of diagnostic features increases the accuracy of differential diagnosis of MF and PP from 59.1 to 81.8%.
