TSN affects the apoptosis of glioma cells. (A) Cell apoptosis analysis of U-138MG or U-251MG cells after TSN treatment (0nM, 50nM, 100nM, 150nM). Apoptosis rates were quantified and shown as histograms. (B) The protein levels of Cleaved caspase-3 and Cleaved PARP in U-138MG or U-251MG cells after TSN treatment (0nM, 50nM, 100nM, 150nM), as determined using Western blotting. Relatively, quantitative results were determined by ImageJ and shown as histogram. The data are expressed as the mean ± SEM, *P < 0.05, **P < 0.01.
