CART is expressed abundantly in the hypothalamic paraventricular nucleus and locus coeruleus, major corticotropin releasing factor (CRF) and noradrenaline sources, respectively. There is a bidirectional relation between CART and hypothalamo-pituitary-adrenal axis activity. CART stimulates CRF, adrenocorticotropic hormone and glucocorticoid secretion, whereas CRF and glucocorticoids increase the transcriptional activity of the CART gene; adrenalectomy declines CART expression in the hypothalamus. Stress exposure modulates CART expression in hypothalamus and amygdala in rat brain in a region and sex specific manner. CART may be a mediator peptide in the interaction between stress, drug abuse, and feeding. The review discusses the established role of CART as it relates to the stress response.
可卡因-安非他明调节转录肽(CART)在下丘脑室旁核和蓝斑中大量表达,分别是促肾上腺皮质激素释放因子(CRF)和去甲肾上腺素的主要来源。CART与下丘脑-垂体-肾上腺轴活动之间存在双向关系。CART刺激CRF、促肾上腺皮质激素和糖皮质激素的分泌,而CRF和糖皮质激素则增加CART基因的转录活性;肾上腺切除术会降低下丘脑CART的表达。应激暴露以区域和性别特异性方式调节大鼠脑中下丘脑和杏仁核的CART表达。CART可能是应激、药物滥用和进食之间相互作用的一种介质肽。本文综述讨论了CART在应激反应中的既定作用。
