MUC1 was shown to induce BRN2, an NEPC-associated transcription factor, through MYC-mediated mechanism, and silencing MUC1 caused suppression of BRN2.This study highlights the significance of MUC1 in prostate cancer lineage plasticity, making it an attractive target for therapeutic inter-vention. The gene discussed is MUC1; the disease is Familial prostate cancer.
