MITF and melanoma: Reports published since our study began have also demonstrated the tumour-suppressor ability of miR-211 in invasion assays only in melanoma cell lines and have identified a number of targets, including transforming growth factor receptor II and the BRN2 transcription factor, which represses expression of MITF, the master transcription factor regulator for melanocytes (Levy et al, 2010; Mazar et al, 2010; Boyle et al, 2011).
