VIM and Familial prostate cancer: Recently, two sORFs have been identified within the human pri-miRNA of miR-200a and miR-200b, a 187 amino acid ORF (coding miPEP200a) and a 54 amino acid ORF (coding miPEP200b), and overexpression of these HA-tagged-miPEPs in PC3 prostate cancer cells inhibited their migration and downregulated the vimentin expression [12].
