WebOct 3, 2012 · Our previous studies of another long-lived subterranean rodent, the naked mole rat (Heterocaphalus glaber), identified a novel anticancer mechanism termed early contact inhibition (ECI) ().Naked mole rat cells proliferate slowly in culture and display hypersensitivity to contact inhibition ().Abrogation of ECI makes naked mole rat cells … WebApr 12, 2024 · Contact inhibition is a regulatory mechanism that functions to keep cells growing into a layer one cell thick (a monolayer). If a cell has plenty of available substrate space, it replicates rapidly and moves freely. This process continues until the cells occupy the entire substratum. At this point, normal cells will stop replicating.
WebJun 2, 2014 · This work solves longstanding mysteries in the field of contact inhibition (CI), cancer, and aging. As shown here during CI, cells do not undergo senescence, thus resuming proliferation after replating. We found that CI was associated with inhibition of the mammalian target of rapamycin (mTOR) pathway, which is required for the senescence … WebJul 1, 2014 · The researchers dubbed this hypersensitivity early contact inhibition, and found that it is regulated by two genes: p16 and p27 (ref. 2).
