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...

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...
Therefore, the LTP can be considered as a chain of biochemical reactions with a positive feedback loop. In this study, we investigated numerically the role of interactions in a chain of biochemical reactions with a positive feedback on the bistable behavior or memory. We conclude that the ...
In this study, for the first time, we found that IMPDH1-assembled cytoophidia translocated YB-1 into the cell nucleus and correlated with tumor metastasis. IMPDH1 and YB-1 formed an autoregulatory positive feedback loop. Our findings reveal the function and mechanisms of IMPDH1 in tumors. Th...
Synthetic gene circuits are often engineered by considering the host cell as an invariable 'chassis'. Circuit activation, however, may modulate host physiology, which in turn can substantially impact circuit behavior. We illustrate this point by a simple
