WebFeb 2, 2024 · A growing body of evidence suggests that excess stress could aggravate tumor progression. The paraventricular nucleus (PVN) of the hypothalamus plays an important role in the adaptation to stress because the hypothalamic–pituitary–adrenal (HPA) axis can be activated by inducing the release of corticotropin-releasing hormone (CRH) … WebOct 12, 2024 · AAV-Retro-EF1a-DIO-EYFP was infected into the VTA of CRH-ires-Cre mice, and VTA-projecting CRH neurons tagged with EYFP in the CeA, the bed nucleus of stria terminals (BNST), and the paraventricular nucleus of the hypothalamus (PVN) were detected. c-Fos expression was increased in CRH CeA→VTA and CRH BNST→VTA …
WebMar 1, 2024 · The activation of paraventricular nucleus (PVN) CRH neurons with … Acute stress is a potent suppressor of pulsatile luteinizing hormone (LH) secretion, but the mechanisms through which corticotrophin-releasing hormone (CRH) neurons inhibit gonadotropin-releasing hormone (GnRH) release remain unclear. WebTo investigate whether the neuronal accumulation of CRH in the GAD67 +/GFP mice is altered under stressful conditions, we performed CRH immunohistochemistry on the PVN after a single 30-min bout of restraint-induced stress (Fig. 2, G and H).The density of the CRH-immunoreactive cells in the PVN increased after a bout of restraint-induced stress …
WebApr 24, 2014 · CRH is highly expressed in PVN neurons and, when centrally injected, inhibits food intake and reduces body weight in rats. Peripheral administration of human CRH increases energy expenditure and fat oxidation in humans. Leptin infusion stimulates CRH expression, while pretreatment with a CRH antagonist attenuates the leptin-induced …
