家蠶提取物對(duì)T2DM小鼠的降血糖作用及其機(jī)制研究摘要：

目的：本研究旨在探究家蠶提取物對(duì)T2DM小鼠的降血糖作用及其機(jī)制研究。

方法：首先，我們建立了高脂飲食和低劑量鏈脲佐菌素誘導(dǎo)的T2DM小鼠模型，并觀察了家蠶提取物對(duì)T2DM小鼠血糖的影響。其次，通過ELISA分析了家蠶提取物對(duì)胰島素分泌的影響，并通過Westernblotting分析家蠶提取物對(duì)胰島素受體、AMPK和GLUT4表達(dá)的影響。

結(jié)果：我們發(fā)現(xiàn)，與對(duì)照組相比，給予家蠶提取物治療的T2DM小鼠血糖水平顯著降低。ELISA結(jié)果表明，家蠶提取物能夠增加胰島素的分泌。同時(shí)，Westernblotting結(jié)果表明，家蠶提取物能夠增加胰島素受體、AMPK和GLUT4的表達(dá)水平，從而促進(jìn)葡萄糖的攝取和利用。

結(jié)論：家蠶提取物能夠通過影響胰島素的分泌和作用途徑來降低T2DM小鼠的血糖水平。因此，家蠶提取物具有很大的潛力成為T2DM的治療藥物。
