Negative feedback is not the only type of feedback control that exists. The human body also uses positive feedback loops. In positive feedback, the signal continues to be amplified. The relationship between the signal and the response to the signal is direct, meaning that both the signal and...
The connection between positive feedback and instability has been widely observed in network theory. In this paper several points are made regarding this connection from the point of view of developing a criteria for determining which models from a class of possible models are unstable or admit an...
Systems Biology Meets Single-Cell Physiology: Role of a Positive-Feedback Signal Transduction Network in Cerebellar Long-Term Synaptic Depression 来自 Springer 喜欢 0 阅读量: 27 作者:K Tanaka,GJ Augustine 摘要: It is widely assumed that persistent changes in the brain, such as those occurring ...
Positive feedback loops are common regulatory elements in metabolic and protein signalling pathways. The length of such feedback loops determines stability and sensitivity to network perturbations. Here we provide a mathematical analysis of arbitrary length positive feedback loops with protein production an...
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.
Mechanistically, IMPDH1 and YB-1 formed an autoregulatory positive feedback loop: IMPDH1 maintained YB-1 protein stabilization; YB-1 induced IMPDH1 expression by binding to the IMPDH1 promoter motif. Functionally, IMPDH1-assembled cytoophidia physically interacted with YB-1 and translocated YB-1 ...
we found that the expression of miR-16-5p is largely induced by EV71, meaning that EV71 infection promotes the pri-miR-16-1 process into mature miR-16-5p. As the host gene of miR-16-1, the primary transcript of DLEU2 contains the pri-miR-16-1 sequences, which can further be proces...
Unravelling biosphere feedback mechanisms is crucial for predicting the impacts of global warming. Soil priming, an effect of fresh plant-derived carbon (C) on native soil organic carbon (SOC) decomposition, is a key feedback mechanism that could release

HB-EGF mimics EGF in EGFR signaling, and since HER2+ BC was demonstrated to induce NF-κB [34], which activates TWIST1 expression [17], HB-EGF might support a positive feedback loop in HER2+ BC. Considering our microarray dataset, the most interesting results involved the downregulation of...
