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 3. FZU-0038-056 decreases the expression of anti-apoptosis proteins and increased p38 phosphorylation in HCC1806 and HCC1937 cells. (A) HCC1806 and HCC1937 cells were treated with FZU-0038-056 (2.5, 5, 10 μM) for 24 hours. Cell lysates were collected for immunoblotting to test the protein levels of cleaved Caspase-3, and PARP, Bcl-2, XIAP, Mcl-1; Bax, Bak and DR5. β-actin was used as the loading control. The quantification data of cl-caspase-3 and Bcl-2 protein expression were shown under the immunoblot images. (B) HCC1806 and HCC1937 cells were treated with FZU-0038-056 (2.5, 5, 10 μM) for 24 hours. The protein levels of p38, p-p38, AKT, p-AKT, ERK, p-ERK, JNK and p-JNK were examined by WB. GAPDH was used as the loading control. The quantification data of p-p38 protein expression was shown under the immunoblot images.
