Cells . 2022 Oct; 11(20). PMID: 36291140
Reprogramming of energy metabolism is regarded as one of the hallmarks of cancer; in particular, oncogenic RAS has been shown to be a critical regulator of cancer metabolism. Recently, asparagine...

Hanada K, Kawada K, Nishikawa G, Toda K, Maekawa H, Nishikawa Y, et al.
Cancer Lett . 2021 Sep; 522:129-141. PMID: 34543685
Mutations of KRAS gene are found in various types of cancer, including colorectal cancer (CRC). Despite intense efforts, no pharmacological approaches are expected to be effective against KRAS-mutant cancers. Macropinocytosis...
