While EGFP-AR-FL was found mainly in the nucleus and with a relatively low level of expression in the cytoplasm of individual prostate cancer cells transfected with pEGFP-AR-FL, expression of EGFP-AR-V7 was found predominantly in the nucleus of individual prostate cancer cells transfected with pEGFP-AR-V7. This evidence concerns the gene AR and prostate carcinoma.
