Hypothalamic agouti-related protein messenger ribonucleic acid is inhibited by leptin and stimulated by fasting.
Agouti-related protein (AGRP) is a homologue of the agouti gene product and, when overexpressed, promotes obesity. Like neuropeptide Y (NPY) messenger RNA (mRNA), AGRP mRNA is produced in the hypothalamic arcuate nucleus and is elevated in leptin-deficient ob/ob and leptin-resistant db/db mice. These data suggest that AGRP mRNA might be affected by leptin and nutritional status in parallel with...
متن کاملSignal transducer and activator of transcription (stat) binding sites but not stat3 are required for fasting-induced transcription of agouti-related protein messenger ribonucleic acid.
Energy homeostasis depends on the regulation of hypothalamic neurons by leptin, an adipocyte hormone whose circulating levels communicate body energy stores. Leptin activates the transcription factor signal transducer and activator of transcription 3 (Stat3) in hypothalamic neurons, including neuronal subtypes producing Agouti-related protein (Agrp), a neuropeptide that stimulates feeding. Prev...
متن کاملRegulation of steroidogenic acute regulatory protein and luteinizing hormone receptor messenger ribonucleic acid in hen granulosa cells.
The regulation of steroidogenic acute regulatory protein (StAR) in vitro by gonadotropins was investigated in granulosa cells from prehierarchal and preovulatory hen follicles. Basal levels of StAR messenger RNA (mRNA) in undifferentiated granulosa cells from prehierarchal (6- to 8-mm) follicles were consistently low, but detectable, and were significantly increased by treatment with 8-bromo-cA...
متن کاملEffects of chronic renal failure on protein synthesis and albumin messenger ribonucleic acid in rat liver.
Previously we reported that chronic renal failure in rats leads to preferential disaggregation of liver membrane-bound polysomes associated with a decrease in albumin synthesis. To determine whether reduced albumin synthesis results from reduced cellular levels of albumin messenger RNA (mRNA) or some other molecular mechanism, we have employed mRNA-DNA hybridization in conjunction with cell-fre...
