K-ras proto-oncogene exhibits tumor suppressor activity as its absence promotes tumorigenesis in murine teratomas.

Abstract excerpt

Ras proteins transduce signals from membrane-bound receptors via multiple downstream effector pathways and thereby affect fundamental cellular processes, including proliferation, apoptosis, and differentiation. K-ras activating mutations play a key role in neoplastic progression and are particularly prevalent in colorectal, pancreatic, and lung cancers. The present study addressed whether the K-ras proto-oncogene...
