资源简介:
(a) By TUNEL, detection of apoptotic cells in the myocardium (see arrows) and heart vessel (see arrowheads). At the bottom, a typical striated-like pattern immunostaining of vinculin (see arrows). (b) Caspase-3 expression in the hearts. (c) Masson staining for wistar, GK and GK-treated hearts showing ECM accumulation (green-blue staining) (n=10, each group). (d) ECM protein [pro-type-I collagen and fibronectin (FN)] levels, and pro-fibrotic mRNA expression (TGFß1 and CTGF) (n=10, each group). *p<0.05 and **p<0.01 vs. wistar. †p<0.05 and ††p<0.01 vs. GK rats.
(a) 采用TUNEL法(TUNEL)检测心肌(箭头指示)及心脏血管(箭头头指示)中的凋亡细胞;下方可见典型条纹状的肌纤蛋白(vinculin)免疫染色阳性信号(箭头指示)。
(b) 心脏组织中半胱氨酸天冬氨酸蛋白酶-3(Caspase-3)的表达水平。
(c) 对Wistar、GK及GK干预组大鼠心脏组织进行Masson染色,可见细胞外基质(ECM)呈蓝绿色蓄积染色,每组n=10。
(d) 细胞外基质蛋白[前Ⅰ型胶原蛋白及纤连蛋白(FN)]的表达水平,以及促纤维化相关mRNA的表达情况(转化生长因子β1(TGFβ1)与结缔组织生长因子(CTGF)),每组n=10。
与Wistar组相比,*p<0.05、**p<0.01;与GK大鼠组相比,†p<0.05、††p<0.01。
