ras activity and cyclin D1 expression: An essential mechanism of mouse skin tumor development
1 Jan 1999
Abstract excerpt
ras is a family of small GTP-binding proteins that transduce signals from tyrosine-kinase receptors to the nucleus and thus play a role in the regulation of cell proliferation and differentiation. Several lines of evidence have shown that the cell-cycle machinery, specifically the circuit cyclin D1/cyclin-dependent kinase (cdk) 4 and 6-p16-pRb, lies downstream of ras. Point mutations that activate the ras protein...
