MAP2K7 and melanoma: In line with previous studies that linked RAF and MEK/ERK activation to cytoplasmic retention and nuclear export of MITF in melanoma cells, respectively (Estrada et al, 2022; Ngeow et al, 2018), we here demonstrate in MCs that MEK and ERK inhibition reverted the low nuclear MITF and melanin production in FN-exposed MCs.
