In our MTT analysis, prostate cancer cells (PC3 and LNCap cell lines) (Figure 6A), lung cancer cells (H1299 and A549 cell lines) (Figure 6B), colorectal cancer cells (LOVO and SW480 cell lines) (Figure 6C), bladder cancer cells (EJ and T24 cell lines) (Figure 6D), and ovarian cancer cells (Hey cell line) (Figure 6F) were all separately transfected with PinX1 siRNA. The gene discussed is PINX1; the disease is prostate carcinoma.
