Figure 5. WA treatment inhibits complex III activity in MDA-MB-231 breast cancer cells.

Mitochondrial complex enzyme activities were determined using lysates from MDA-MB-231 cells treated for 6 h with DMSO or 5 µM WA. Results shown are mean ± SD (n = 3). *P<0.05; **P<0.01, significantly different compared with control by Student's t-test.
