We have reported that glucocorticoids increase steady state insulin receptor mRNA levels in target cells. In the present study using IM-9 cultured human lymphocytes, we investigated the mechanism responsible for this glucocorticoid mediated increase in insulin receptor mRNA levels. Incubation of IM-9 cells with 100 nM dexamethasone for 4 h stimulated a parallel increase in both polysomal and nu...

Regulation of the mu-opioid receptor gene by opioid analgesic drugs has not been observed in rats and mice following in vivo treatments that produce tolerance. Although in vivo heterologous regulation of mu-opioid receptor mRNA by non-opioid compounds has been reported, the failure to observe changes in mu-opioid receptor mRNA levels in vivo after treatment with opioid agonists raised the possi...

Recent studies have shown that the administration of endotoxin (LPS) and cytokines to Syrian hamsters increases serum cholesterol levels, hepatic cholesterol synthesis, and the activity, protein levels, and mRNA levels of hepatic HMG-CoA reductase. Despite the greater than 10-fold increase in HMG-CoA reductase mRNA levels, LPS had only minimal effects on hepatic LDL receptor mRNA levels. In the...

Sex and species differences in androgenic regulation of steroid hormone receptor mRNAs were examined in the diencephalon of two species of whiptail lizards: Cnemidophorus inornatus is a sexual species and the direct evolutionary ancestor to Cnemidophorus uniparens, an all-female parthenogenetic species. Lizards were gonadectomized and treated with different doses of either aromatizable testoste...

Using in situ hybridization techniques, the expression of 5-HT1A receptor mRNA was measured within the hippocampal formation after bilateral adrenalectomy (ADX). After 24 hr ADX, 5-HT1A receptor mRNA expression was significantly increased in all hippocampal subfields in ADX animals relative to sham-operated controls (SHAM). The magnitude of the increase was most pronounced within CA2 (127%) and...

background: there is evidence that cd36 promotes foam cell formation through internalizing oxidized ldl (ox-ldl) into macrophages therefore, it plays a key role in pathogenesis of atherosclerosis. in addition, cd36 expression seems to be mediated by nuclear receptor peroxisome proliferator-activated receptor gamma (ppar-γ). the aim of the present study was to evaluate and compare the effect of ...

background: nephrotic syndrome is a disorder that leads to hyperlipidemia. l-carnitine and genistein can effect on lipid metabolism and the syndrome. in the present study, we have delved into the separate and the twin-effects of l-carnitine and genistein on the gene expressions of hmg-coa reductase and ldl receptor in experimental nephrotic syndrome. methods: in this controlled experimental stu...

the purpose of the present study is to investigate the prevalence of th17 and regulatory t (treg) cells in children with allergic rhinitis (ar) accompanying with bronchial asthma (ba).24 children with ar, 22 children with ba, 18 children with ar accompanying with ba,and 20 healthy controls were recruited. the prevalence of peripheral blood th17 and treg cells were determined by flow cytometry. ...

Nerve growth factor (NGF) is a target-derived neurotrophic protein that promotes the survival and growth of developing sympathetic and sensory neurons. We have examined NGF receptor gene expression in these neurons after NGF administration. Northern blot and in situ hybridization analyses demonstrated that NGF given systemically to neonatal rats increased levels of NGF receptor mRNA in sympathe...

Background: There is evidence that CD36 promotes foam cell formation through internalizing oxidized LDL (ox-LDL) into macrophages therefore, it plays a key role in pathogenesis of atherosclerosis. In addition, CD36 expression seems to be mediated by nuclear receptor peroxisome proliferator-activated receptor gamma (PPAR-γ). The aim of the present study was to evaluate and compare the effect of ...
