Effects of overexpression of MITF cDNA in three different melanoma cell lines (A–C) and the human melanocyte NHEM cell line (D) on expression of BPTF, BCL2, BCL-XL, and CCND2. The expression level of CCND2 was undetectable in D04, SKMEL-28, and D05 cells. In all panels data presented reflect mean ± SEM of three replicates. *P < 0.05.
