We examined whether miRNAs that commonly target transcripts to block their translation are involved in regulation of INPP4B by comparing miRNA expression profiles between melanoma cell lines expressing relatively high levels of the INPP4B protein (Mel-RM and ME4405) and those with low levels (MM200 and ME1007) using TaqMan® Low Density miRNA Array [38]. Here, INPP4B is linked to melanoma.
