background: leptin and adiponectin are the two key metabolic hormones secreted from adipocytes to control food intake and energy expenditure. the action of both hormones in regulation of gonadotropin releasing hormone (gnrh) secretion from the hypothalamus is mediated through kisspeptins. kisspeptins are products of kiss-1 gene. leptin and adiponectin are modulators of kiss-1 expression in the ...

objective: chronic myeloid leukemia (cml) is a malignant clonal disorder of hematopoietic stem cells which results in increase of myeloid cells, erythroid cells and platelets in the peripheral blood and hyperplasia in bone marrow. investigations have shown different types of bcr- abl variants in these patients. in iran only 3 types of these variants have been identified because most of the clin...

background: recently, reports have indicated a role for the membrane form of toll-like receptor 2 (tlr2) in asthma pathogenesis. in this study we examined soluble tlr2 levels in serum and sputum of asthmatic and healthy subjects. methods: serum and sputum samples were obtained from 33 asthmatic and 19 healthy subjects. the asthmatics were classified into four groups according to the global init...

abstract objective: the previous studies indicated that the tlrs especially toll-like receptor 4) tlr4 (are involved in the process of diabetes. the aim of the present research was to investigate the time course expression pattern of tlr4-a main component of innate immune system- in mrna levels in the heart tissue of diabetic male wistar rats. materials and methods: in this research, adult wist...

hydrogen sulfide (h2s) has been shown to protect the gastric mucosa through several protective mechanisms but till now its effect on mrna expression of sodium bicarbonate cotransporter 1 (nbc1), trefoil factor1 (tff1) and trefoil factor2 (tff2) was not investigated. this study was aimed to evaluate the effect of h2s on mrna expression of nbc1, tff1 and tff2 in rat gastric mucosa in response to ...

The machinery regulating the transcription and processing of the human immunodeficiency virus type 1 (HIV-1) genome has been extensively studied for the past two decades, leading to the characterization of a complex set of interactions between viral and cellular factors. Our understanding of the basic molecular mechanisms regulating the expression of cellular genes has been greatly advanced by ...

background and aims: there has been scant information concerning antihypertrophic effects of vitamin d specifically on its cellular and molecular mechanisms. sirtuin 1 (sirt1) is regarded as a key deacetylase enzyme in cardiomyocytes which applies potential cardioprotective effects by functional regulation of different proteins. this study aimed to evaluate the effects of 1, 25-dihydroxyvitamin...

Background: The aim of the current study was to assess the mRNA levels of two mitochondria-related genes, including nuclear-encoded NRF1 (nuclear respiratory factor 1), mitochondrial transcription factor A (TFAM), and mitochondrial-encoded cytochrome c oxidase subunit 1 (MT-CO1) genes in various stages of the human oocyte maturation. Methods: Oocytes were obtained from nine infertile women wit...

Developing a safe and effective preventive for HIV-1 remains the hope controlling global AIDS epidemic. Recently, mRNA vaccines have emerged as promising alternative to conventional vaccine approaches, primarily due their rapid development potential low-cost manufacture. Despite advantages of vaccines, challenges remain, especially adverse effects delivery vehicle low efficiency. As result, Lun...
