The impact of KRAS mutations is heavily dependent on the order of mutations. Primary KRAS mutations generally lead to a self-limiting hyperplastic or borderline lesion, but if they occur after a previous APC mutation it often progresses to cancer. [18] KRAS mutations are more commonly observed in cecal cancers than colorectal cancers located in ...
RALD is caused by gain-of-function somatic mutations in the genes NRAS or KRAS. NRAS and KRAS are members of the RAS subfamily and are implicated in many types of cancer. [5] Somatic mutations are changes in DNA that occur after conception. Although generally somatic mutations can develop in any cell of the body, in RALD the somatic mutations ...
RMC-9805 is an investigational drug that selectively targets the G12D mutation in KRAS dependent cancers. [1] [2] [3] RMC-9805 functions as molecular glue that forms a non-covalent ligand-mediated protein-protein interaction between cyclophilin A and GTP-bound RAS.
It is a tetravalent vaccine that targets G12D, G12V, G13D or G12C driver mutations in the KRAS gene. [2] It is currently being evaluated for the treatment of either non-small cell lung cancer, colorectal cancers with microsatellite instability, or pancreatic adenocarcinoma, all with confirmed KRAS driver mutations.

The three Ras genes in humans (HRAS, KRAS, and NRAS) are the most common oncogenes in human cancer; mutations that permanently activate Ras are found in 20 to 25% of all human tumors and up to 90% in certain types of cancer (e.g., pancreatic cancer). [2]

HCT116 cells have a mutation in codon 13 of the KRAS proto-oncogene, and are suitable transfection targets for gene therapy research. [2] The cells have an epithelial morphology and can metastasize in xenograft models. [1] When transducted with viral vectors carrying the p53 gene, HCT116 cells remain arrested in the G1 phase. [3]
Sotorasib is the first approved targeted therapy for patients with tumors with any KRAS mutation, which accounts for approximately 25% of mutations in non-small cell lung cancers. [5] KRAS G12C mutations occur in about 13% of patients with non-small cell lung cancers. [5]
