The effect of hypoxia on proliferation of cultured bovine retinal pigment epithelial cells and expression of the antiapoptotic protein bcl-2 / 中华眼底病杂志

ABSTRACT

Objective To study the effect of hypoxia on proliferation of cultured bovine retinal pigment epithelium (RPE) cells and expression of the antiapoptotic protein bcl-2. Methods The bovine RPE cells were cultured under normal and hypoxic chamber respectively. After 24 hours, the proliferation of RPE cells was evaluated by[3-(4,5-dimethylthiazole-2yl)-2,5-diphenyl tetrazolium bromide, MTT]-test. At the same time, anti-bcl-2 protein antibody was examined by immuno-histochemistry method. Results The A value in the hypoxia group was higher than that in the normal group after 24 hours (P
