MITF and melanoma: As lower levels of the melanoma specific transcription factor MITF (micropthalmia-associated transcription factor) are associated with increased invasiveness in melanoma cells [29,30], we examined the protein levels of MITF in 130429 and 160915 cell lines 30 min and 24 h post-0.1 μM anisomycin treatment; however, we did not observe any difference (Figure 3, top and middle panel).
