Figure 5.
Several cell lines (1889c, HaCat, TE167, and PC3) were transfected using si-BIRC3 for 48h, which significantly repressed expression of (A) Birc3 mRNA ****p < 0.0001 in 1889c, HaCat and TE167 cells and ***p = 0.0002 in PC3) and (B) Birc3 protein. After transfection. Changes of the cytology of transfected cells is shown in (C). Cells were stained with an antibody to cleaved caspase 3 for apoptosis detection (immunoperoxidase ×20) (D). FACS analysis to quantify apoptosis using Annexin V-FITCS/PI (E). All experiments were done in triplicate and each measurement in duplicate. Similar low levels of apoptosis following si-BIRC3 transfection were observed in A549 (lung carcinoma); MCF7 (breast carcinoma); and HeLa (cervical adenocarcinoma) cells.
