Pyrrolo [3,4-b]-quinolin-9-amine compound FZU-0038-056 suppresses triple-negative breast cancer partially through inhibiting the expression of Bcl-2
Figure 5. FZU-0038-056 induced apoptosis partially via inhibiting Bcl-2 in HCC1806 cells. (A) Bcl-2 was overexpressed in HCC1806 cells through a lentivirus system. (B) Overexpression of Bcl-2 reduced the cell viability inhibition triggered by FZU-0038-056. Cell viability was measured by the SRB assay. *p < 0.05. (C) FZU-0038-056-induced apoptosis were partially rescued by the overexpression of Bcl-2 compared with the control cells, as measured by Annexin V staining and flow cytometry analysis. Annexin V positive cell populations were quantified and shown on the right side. *p < 0.05. (D) FZU-0038-056-induced apoptosis were partially rescued by the overexpression of Bcl-2, as measured by Caspase-3 and PARP cleavage. The cells were treated with DMSO or FZU-0038-056 (10 μM) for 24 hours, and cell lysates were collected for WB analysis. β-actin was used as loading control.
