目的观察二氢杨梅素(DHM)对高脂饮食诱导的肥胖小鼠肩胛下脂肪组织棕色化的影响,并阐明其机制。方法C57bl/6j小鼠采用普通饲料和高脂饲料喂养,同时分别用或不用低剂量(125 mg·kg~(-1)·d~(-1))或高剂量(250 mg·kg~(-1)·d~(-1))的DHM处理16W。实验期间每4周测一次小鼠体质量, 16周后小鼠空腹过夜测空腹血糖,接着处死小鼠,测量体长后算出Lee’s指数,随后取肩胛下脂肪组织,一部分HE染色观察脂肪细胞形态,另一部分通过实时定量PCR和蛋白质免疫印迹法检测肩胛下脂肪组织:解偶联蛋白1(UCP1)、锌指转录因子PR结构域包含子16(Prdm16)、腺苷酸活化蛋白激酶(AMPK)、过氧化物酶体增殖激活受体γ(PGC1α)...

Aim To observe the effect of dihydromyricetin (DHM) on the browning of subscapular adipose tissues in the high-fat diet fed obese mice, and clarify the mechanism. Methods C57BL/6J mice were fed with normal and high-fat diet, and were treated with or without low dose (125 mg • kg"1 • d"1) or high dose (250 mg • kg"1 • d"1) DHM for 16W. The body mass of mice was measured every four weeks during the experiment. After 16 weeks, the mice were fasted overnight. Blood samples were taken for fasting blood glucose. The mice were then sacrificed and ...
