Only a few reports have been published, including research on UGT expression in melanocytes derived from newborn foreskin tissues, with UGT2B isoforms (UGT2B7, UGT2B10, and UGT2B15) being expressed primarily in normal melanocytes as well as in a primary melanoma cell line [40,41]. This evidence concerns the gene UGT2B15 and melanoma.
