β-catenin mRNA levels in RWPE-1, PC-3, DU-145, and LNCaP cells. Gene expression levels were quantified using RT-qPCR and normalized to the levels of GAPDH expression. Data are plotted as the mean ± s.e.m. of the 2^-ΔCT values, and three independent experiments were performed. Expression levels in prostate cancer cells were compared with those in the normal prostate cell line (RWPE-1) using Dunnett’s test. * p < 0.05; **** p < 0.0001
