Snail expression correlates inversely with maspin expression in normal and prostate cancer cell lines. Normal immortalized epithelial cells (PrEC), the LNCaP prostate cancer progression model (LNCaP, C4-2), DU145 and 22Rv1 cells were utilized to analyze Snail and maspin levels by (A) PCR and (B) Western blot analyses. GAPDH and actin were utilized as loading controls for PCR and Western blot analysis, respectively. All experiments were performed at least 3 times.
