MYC and pancreatic neoplasm: By constructing dFdC-resistant pancreatic cancer Panc-1 cells, our data found that the expression of c-Myc and PD-L1 was significantly elevated, suggesting c-Myc and PD-L1 may be novel prognostic biomarkers in pancreatic cancer, and inhibiting c-Myc and PD-L1 may be a potential strategy to rescue dFdC resistance in pancreatic cancer therapy.
