The present study correlates Snail expression with prostate cancer, as Snail protein was absent in normal immortalized prostate epithelial cells (PrEC), however it was then expressed in our LNCaP progression model (LNCaP, C4-2), DU145 prostate cancer cell lines, though undetectable in 22Rv1 cells. Here, SNAI1 is linked to prostate carcinoma.
