(A) Western-blot analysis of PTEN expression in prostate cancer cell lines stably expressing Slug shRNA. 22RV1 (left panel) and DU145 (right panel) cells were infected with lentiviruses expressing SLUG-specific shRNAs and control shRNA, and then selected with puromycin and expanded. Total protein was extracted from respective cell lines and analyzed by Western-blot analysis using anti-SLUG, anti-pAKT, anti-PTEN and anti-GAPDH (loading control) antibodies, respectively.
(B) qPCR analysis of PTEN transcripts in stable cell lines expressing SLUG-specific shRNAs and control shRNA. ** p < 0.01.
