Study on gene expression of the key enzymes in primary metabolism from Whitmania pigra Whitman during hibernation
Abstract： The experimental purpose is to explore the related enzyme gene expression of sugar, fat, protein synthesis to understand the mechanism of W. Pigra metabolism during hibernation.The methods is to select the W. Pigra in different stages of hibernation as material,The gene expression of key enzymes in substance metabolism at different stages was measured by real-time quantitative PCR.The results showed that the expression of PK, FBP, PEPCK, ACC, HSL, TLSP, AST and GDH in the digestive tract increased first and then decreased during hibernation,except for the FBP gene in the muscle during hibernation, it was the first to decrease and increase and decrease, the decrease was the trend of the other genes,It reached the highest level before and after 60 days, and the difference was remarkable（P＜0.05）. The W. Pigra will reduce their metabolism during hibernation early during hibernation with growth time, will provide energy through the consumption of their own material.

蚂蟥冬眠过程中糖、脂肪、蛋白质关键酶基因表达的研究
蚂蟥（Whitmania pigra Whitman），水蛭科动物，别名宽体金线蛭，其干燥全体是药材水蛭的主要基原动物，具有破血消症，逐瘀通经的功效[1]，是治疗心脑血管中成药的主要原料。近年来由于野外生存环境污染和市场需求的加大，蚂蟥的供需矛盾日益凸显，人工养殖备受重视。
