Zhoushi Qiling decoction induces apoptosis of human prostate cancer cells via miR-143/Bcl-2 axis


Figure 5. Zhoushi Qiling decoction effects caspase-3 activity and Bax and Bcl-2 expression levels via miR-143 in DU145 cells. (A) Bcl-2 was predicted as a direct target of miR-143 by the online software Targetscan. (B) Luciferase reporter assay was conducted in DU145 to verify the direct binding between miR-143 and Bcl-2. Relative miR-143 (C) and Bcl-2 mRNA (D) levels were detected by qRT-PCR. Western blot was performed to measure the protein expression of caspase-3, Bax and Bcl-2 (E) in different groups and relative protein expression levels (F) were quantified. Data were expressed as mean ± SD from three independent experiments with triple replicates per experiment. * p < 0.05, ** p < 0.01 compared with control group. &p < 0.05 compared with ZQD-50 group.
