POU3F2 and melanoma: MiR-211 is encoded within the sixth intron of TRPM1, a candidate suppressor of melanoma metastasis [49]–[50], and previous researches demonstrated that overexpression of miR-211 inhibited both anchorage-independent colony formation and invasion, through regulation of IGF2R, TGFBR2, NFAT5 and BRN2 [51]–[52].
