We examined the effects of olaparib on the mRNA expression of markers related to migration, invasion, and adhesion, Ki67, Vimentin, E-Cadherin, β-catenin, MMP2, MMP9, p53, and integrin α2 and β1, in all three cancer cell lines by quantitative real-time PCR (Figure 5). This evidence concerns the gene MKI67 and cancer.
