Human (HCT116, DLD-1) and murine (CT26) KRAS-mutant CRC cell lines, as well as KRAS-mutant lung cancer (H23, H727) and pancreatic ductal adenocarcinoma (PANC1) cells, were grown in control medium (1 g/L glucose and 10% serum; CTR) or in a FMD-like medium (0.5 g/L glucose and 1% serum), here referred to as short-term starvation condition (STS), which mimics the reduction of extracellular glucose and growth factor concentrations that occurs during prolonged (>48 h) fasting or FMD in vivo, with or without pharmacological concentrations of vitamin C (≥0.3 mM). The gene discussed is KRAS; the disease is lung carcinoma.
