In order to understand whether androgen resistance or independence might be driving EGFR expression, we performed qRT-PCR and Western blot analysis (Figure 5A,B) using five different prostate cancer cell lines (LNCaP, C4-2, DU145, PC3, and LNCaP-FUT8) to evaluate EGFR expression. This evidence concerns the gene EGFR and prostate carcinoma.
