We also detected the expression of MALAT1 in human epidermal melanocytes (HEMa-LP) and three human melanoma cell lines (A375, SK-MEL-5 and SK-MEL-2), and found that MALAT1 was significantly higher in melanoma cells than in human epidermal melanocytes, especially in A375 cells (Figure 1B). The gene discussed is MALAT1; the disease is melanoma.
