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.
This positive feedback mechanism, however, can also pose as a potentially significant liability. In the presence of neuropathology, the positive feedback system may escape central inhibitory controls or may excessively sensitize bladder afferent signaling. The overall result of such a loss of “checks...
RNA immunoprecipitation, pull-down, luciferase reporter, chromatin immunoprecipitation assays were used to investigate the mechanism underlying circ-YAP promoting CRC liver metastasis. CRC liver metastasis animal model was established to assess the effect of circ-YAP in vivo. Results Circ-YAP was notably...

Childbirth is a positive feedback mechanism. When uterine contractions become strong enough to push the baby’s head through the cervix, the stretched cervix sends signals to the pituitary gland to secrete the oxytocin hormone, that circulates in the blood to reach the uterine muscles causing ...
(d) Model for a positive-feedback regulation in KDM5A: newly generated H3K4me0 nucleosomes bind to the PHD1 domain of KDM5A. Occupancy of the PHD1 domain then stimulates the demethylase activity by an allosteric mechanism. catalytic activity of KDM5A. This effect is particularly pro- no...

Reciprocally, HIF2α can increase PVT1 expression by occupying the HRE within the enhancer of PVT1 and form a positive feedback loop, thus the sustained HIF2α will mediate PVT1 oncogenic functions for ccRCC tumorigenesis. Our study not only reveals a potential mechanism of PVT1 playing ...
