In BC, a correlation between STAT3 activation and the transcription of genes promoting angiogenesis (i.e., VEGF and HIFα), proliferation (i.e., cyclin D1, c-Myc), EMT (i.e., vimentin, TWIST) and mobility (i.e., metalloprotease) has been found [16,17]. This evidence concerns the gene MYC and breast cancer.
