A negative feedback loop refers to a circuit or mechanism in which the output of a system is used to regulate or suppress its own activity. It can be implemented through repressive or degradation-inducing interactions, and it helps to maintain stability and reduce variability in gene expression....

Negative feedback in living organisms Negative feedback is a principle which is used by the body in order to return systems to its normal level; it does this by turning the corrective measures off. Homeostasis uses the principle of negative feedback in order to maintain a constant internal env...
Based on the findings of this study and our previous study, we propose that there is a negative feedback loop involving NRF2 and p97. However, this loop becomes disrupted in lung cancer as NRF2 is no longer ubiquitylated by the KEAP1-CUL3-RBX1 E3 complex, resulting in hyperactivation of ...
Our results in vivo demonstrated circ-SNRK overexpression is sufficient to improve the cardiac function post-MI in rats by breaking the feedback loop. Nevertheless, a recent study found that the level of miR-33 in fibroblast (another crucial member of the heart) significantly increase in pressure...
Thus, our findings define a critical role of p66Shc in the suppression of fibrotic EMT response with a negative feedback loop between p66Shc and ZEB1 in lung epithelial cancer cells. Cell Death and Disease (2015) 6, e1708; doi:10.1038/cddis.2015.74; published online 2 April 2015 Owing ...
A feedback mechanism accelerates or inhibits a process. The feedback mechanism among most of the hormones is a negative feedback loop. It occurs when the original effect of the stimulus is reduced by the output.
We illustrate a proposed model of control of NO formation whereby at low concentrations of 4-HNE a negative feedback loop maintains a constant level of NO production with an observed inflection at approximately 1聽碌M, while at higher 4-HNE concentrations positive feedback is observed. Further,...
As a target of miR-17-92, E2F1 has been suggested to induce the transcription of miR-17-92 in several cell types. We sought to investigate whether this negative feedback loop exists in mouse PMCs and what the function of this negative feedback loop would be in PMCs. Our results showed ...
