To investigate the transcriptomes of melanoma cell lines that represent Epgn1 and Epgn3 groups, we first examined the expression of the 122–epigenetic gene signature in 12 BRAF V600 mutant cell lines derived from human primary cutaneous melanomas using a customized NanoString array (Supplemental Table 1.1 and 1.2; supplemental material available online with this article; https://doi.org/10.1172/jci.insight.166611DS1). Here, BRAF is linked to melanoma.
