甲状腺功能亢进激活心肌细胞β-catenin/FoxO1诱导大鼠心室重构的作用
目的探究甲亢激活心肌细胞β-catenin/FoxO1诱导大鼠心室重构的作用和机制。方法通过甲状腺激素(T4 0.1 mg/kg/day;腹腔注射)连续给药30 d构建甲亢诱导心室重构大鼠体内模型。利用β-catenin抑制剂MSAB(14 mg/kg)同时给药30 d,通过Western-blot检测心肌肥厚主要标志物ANP以及β-catenin、FoxO1等蛋白的表达情况;免疫荧光检测β-catenin、FoxO1的核内外表达及分布情况。利用原代培养的乳鼠心肌细胞,使用甲状腺激素(T3 20 nmol/L)处理心肌细胞24 h构建体外甲亢诱导心肌细胞肥厚模型,利用β-cateninsiRN...
