ANGPTL4 induces the expression levels of multiple ATP-dependent transporters and Bcl-xL in tumor cells. (A) The inductive effect of CM or adipocyteshMock or adipocyteshANGPTL4 on the protein expression level of ABCB1, ABCC1, ABCG2 and Bcl-xL in SKOV3 cells. Left, representative images of western blot analysis. Right, statistical analysis of western blot assay. The data are presented as the mean ± SD. **P<0.01 vs. SKOV3.
