Figure 3. Changes in the expression levels of apoptosis-related proteins in cortical and hippocampal regions in the three groups after rTMS treatment. (A) Bax expression in the three groups was examined by immunohistochemistry staining and quantitative histogram analysis. (B) Caspase-3 expression in the three groups was examined by immunohistochemistry staining in three groups and quantitative histogram analysis. (C) Bcl-2 expression- in the three groups was examined by immunohistochemistry staining and quantitative histogram analysis. The data are presented as the mean ± standard deviation (n =5). *P < 0.05 vs. Con group; # P < 0.05 vs. P8 group.
