Fig 2. Effect of complex 4 on MDA-MB-231, MCF-7 and MCF-10A cells.

(A) Cell morphology was examined after 2 h and 24 h of treatment. (B) Clonogenic assay of untreated MDA-MB-231 cells (control) or cells treated with complex (4). A photograph of a representative experiment is shown along with graph quantifications of colony number and size. Significant at the *p<0.005, **p<0.001 levels using ANOVA and Bonferroni tests.
