Interactions between wild-type and mutant Ras genes in lung and skin carcinogenesis.

Abstract excerpt

Ras oncogenes (Hras, Kras and Nras) are important drivers of carcinogenesis. However, tumors with Ras mutations often show loss of the corresponding wild-type (WT) allele, suggesting that proto-oncogenic forms of Ras can function as a suppressor of carcinogenesis. In vitro studies also suggest that WT Ras proteins can suppress the tumorigenic properties of alternate mutant Ras family members, but in vivo evidence...
