A striking observation of our analysis of myosin IC isoform expression in these cell lines are the high expression levels of myosin IC isoform A in the mouse and human prostate cancer cell lines when compared to the normal (non-cancer) prostate cell line RWPE-1 and to other (non-prostate) cancer cell lines as summarized in Table 1. This evidence concerns the gene MYO1C and prostate carcinoma.
