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...
Third, experience also caused some of the between-individual differences in problem-solving performance, and since experience is not reversible, and by definition carries forward into the next stage of the sequential problem-solving process, this suggests a positive feedback loop driving consistency ...
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
Such positive feedback loops have been identified in other examples of QS in numerous species, and these circuits foster accelerated accumulation of the QS pheromone and rapid activation of the target transcriptional program. At high concentrations, active AgrA may slightly prefer P3 over P2 [79],...
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...
