WebContact inhibition in human and mouse cells is mediated by the up-regulation of the cyclin-dependent kinase (Cdk) in-hibitor p27Kip1 (p27§). Early contact inhibition in naked mole rats was, how-ever, associated with the up-regulation of a different Cdk inhibitor, p16Ink4a (p16¶). Cells that bypassed early contact inhibition, either by ... WebOct 26, 2009 · Contact inhibition is a key anticancer mechanism that arrests cell division when cells reach a high density. In cell culture, naked mole-rat fibroblasts arrest at a much lower density than those from a mouse. We demonstrate that early contact inhibition requires the activity of p53 and pRb tumor suppressor pathways.
