Figure Lengend Snippet: Effect of BSAPPT on apoptosis and cycle-related gene or protein expression in MCF-7, MCF7/TAMR and other cancer cells. (A) mRNA expression levels of genes linked to the cell cycle and apoptosis were measured by qPCR both before and after MCF-7 and MCF7/TAMR cells were treated with 10 µg/ml BSAPPT. (B) Western blotting detection of apoptotic and cycle-related protein expression variations in MCF-7 and MCF7/TAMR cells before and after using 10 µg/ml BSAPPT. Results of qPCR analysis that assessed differences in the level of expression of genes linked to the cell cycle and apoptosis before and after (C) A549 and (D) MDA-MB-231 cells were treated with 10 µg/ml BSAPPT. *P<0.05; **P<0.01; ***P<0.001.
