Early contact inhibition
WebFurthermore, uncontrolled growth because of the loss of contact inhibition of proliferation is a hallmark of solid tumors (3, 4). Despite these insights, the underlying regulatory mechanisms of the contact inhibition of proliferation remain poorly understood, although cadherin-mediated cell–cell adhesion is thought to play an important role (2). 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.

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. 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 …
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. As motile cells come into contact in confluent cultures, they exhibit decreased mobility and mitotic activity … 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 …
