For example, MEF2A, a transcriptional regulator implicated in muscle development, cell growth control, and apoptosis, had significantly higher activity in OV, BRCA-BASAL, and UCS; the activity of microphthalmia-associated transcription factor (MITF), was significantly higher in uterine carcinosarcoma than in other cancers and displayed high variation across patients. Here, MEF2A is linked to cancer.
