我们研究了垂体腺苷酸环化酶激活多肽(PACAP)对大鼠摄食的影响,并利用原位杂交技术研究了下丘脑神经肽基因表达的参与。侧脑室注射PACAP(1000 pmol/大鼠)以剂量依赖性方式显著降低摄食量。 在PACAP处理的大鼠中,弓状核中的神经肽Y(NPY)mRNA水平和室旁核中的甘丙肽mRNA水平升高,室旁核中的促肾上腺皮质激素释放激素(CRH)mRNA水平降低。在禁食72 h的大鼠中,NPY mRNA水平升高,CRH mRNA水平降低,但甘丙肽mRNA水平不变。 这些结果表明PACAP的厌食功能不是由NPY或CRH介导的,并且PACAP增加甘丙肽的合成。
We investigated the effect of centrally administered pituitary adenylate cyclase activating polypeptide (PACAP) on feeding in rats, and the involvement of hypothalamic neuropeptide gene expression using in situ hybridization. lntracerebroventricular injection of PACAP (1000 pmol/rat) significantly decreased food intake in a dose‐dependent manner. In PACAP‐treated rats, neuropeptide Y (NPY) mRNA levels in the arcuate nucleus and galanin mRNA levels in the paraventricular nucleus increased, and corticotropin‐releasing hormone (CRH) mRNA levels in the paraventricular nucleus decreased. In rats fasted for 72 h, NPY mRNA levels increased, and CRH mRNA levels decreased, but galanin mRNA levels were unchanged. These results indicate that the anorectic function of PACAP is not mediated by NPY or CRH, and that PACAP increases galanin synthesis.
