The tumour suppressor, miR-137, inhibits malignant melanoma migration by targetting the TBX3 transcription factor

The transcription factor, TBX3, is a key driver of malignant melanoma and any drug that impacts its expression is likely to have an impact on the treatment of this highly aggressive and treatment resistant cancer. Replacement of miRNAs that target oncogenes has gained much attention as a therapy because it is anticipated to be effective with little side-effects since miRNAs are naturally occurring and often target large set of genes in the same oncogenic pathway. Here we show that miR-137 levels correlate inversely with TBX3 mRNA levels in a panel of melanoma cell lines and in a cohort of patients with primary melanoma.
