L-Cysteine alleviates HI-induced apoptosis. (A) TUNEL staining was performed 3 days after HI injury. (B) Analysis of TUNEL-positive cells from result A. Scale bar = 50 µm. Images are representative of triplicate sets. Values represent the mean ± SD. n = 4 in each group. (C) The levels of Bax and Bcl-2 of the ipsilateral cortex were measured 3 days after HI by Western blot and RT-PCR. Quantification of the Bax and Bcl-2levels from Western blot and RT-PCR. Values represent the mean ± SD, ***p < 0.001 HI VS Sham; ##p < 0.01, ###p < 0.001 HI + L-Cys VS HI; &&p < 0.01, &&&p < 0.001 HI + L-Cys + AOAA VS HI + L-Cys.
