T-cell receptor (TCR)-mediated apoptosis in immature thymocytes and T-cell hybridomas is calcium dependent and can be inhibited by cyclosporin A (CsA). Induction of the orphan steroid receptor Nur77 (NGFI-B) is required for activation-induced apoptosis. Here, we examined the regulation of Nur77 expression, in response to apoptotic TCR signals, which consists of kinase C and calcium pathways. We...
Background: Phytoestrogens, a group of plant-derived polyphenolic compounds have recently come into considerable attention due to the increasing information on their potential adverse effects in human health. Some of phytoestrogens show estrogenic activity that may be carcinogenic for human. In the present study, we investigated the transcriptional effects of variety of phytoestrogens ...
1,25 dihydroxyvitamin D (1,25 D) is traditionally viewed as an endocrine hormone produced in the kidney whose function is to regulate calcium homeostasis by influencing intestinal calcium absorption, renal calcium reabsorption, and bone calcium resorption. These effects are mediated at the molecular level by a nuclear receptor of the steroid hormone receptor superfamily, the vitamin D receptor ...
Collecting duct-derived endothelin-1 (ET-1) reduces blood pressure and inhibits Na and water reabsorption. Collecting duct ET-1 production is increased by volume expansion; however, the mechanism by which this occurs is unknown. We hypothesized that intracellular calcium, which is likely to be increased by volume expansion, regulates collecting duct ET-1 synthesis. Rat inner medullary collectin...

background: some of metal ions as environmental pollutants show estrogenic activity. this xenostrogenic compounds can be caused carcinogenicity in organs. the mechanism of carcinogenicity of metal ions is not clarified. objectives: in this study, we investigated the transcriptional effects of variety of metal ions on the bovine oxytocin and the thymidine kinase-ere promoter by estrogen receptor...
abstract: since sugar consumption is directly related to diabetes and other illnesses such as obesity, the issue that will most heavily dominate the health food market is blood sugar management and low glycemic foods. using calcium chloride and gums such as sodium alginate and low ester pectin as thikener and a high-potency sweetener aspartame we were able to reduce sugar content of sour cherry...
Background: The organochlorine DDT has estrogenic activity but the mechanism underlying the estrogenic activity of this pesticide remains unclear. In the present investigation here, we studied the transcriptional effects of a synthetic organochlorine pesticide o,p’-DDT [1.1.1.-trichloro-2-(o-chlorophenyl)-2-p-chloriphenyl ethane] and its metabolite p,p'-DDE (2-2-bis(4/chlorophenyl)-1-1-di...
The 173-base pair proximal promoter of SPRR1A is necessary and sufficient for regulated expression in primary keratinocytes induced to differentiate either by increasing extracellular calcium or by 12-O-tetradecanoylphorbol-13-acetate (TPA) treatment. Whereas calcium-induced expression depends both on an AP-1 and an Ets binding site in this region, responsiveness to TPA resides mainly (but not ...
