PC-3 (not a prostate cancer model) is a model with a molecular subtype of classical tumor and Myc-signal low which are associated with better prognosis in PDAC patients, whereas PC-42 is a model with a molecular subtype of basal-like tumor and Myc-signal high which are associated with poorer prognosis in PDAC patients. This evidence concerns the gene MYC and Familial prostate cancer.
