Learn the difference between positive and negative feedback. Understand what is positive feedback in biology through the use of some positive...
Feedback loopThe feedback loop is information that is obtained from a reaction about the product and this will be used to alter the product. Therefore, the feedback loop in biology will be defined as a system of altering the reaction based on the type of product formed....
Key role of the positive feedback between PGE(2) and COX2 in the biology of myeloid-derived suppressor cells. Oncoimmunology. 2012;1(5):762-764.Obermajer N., Kalinski P. Key role of the positive feedback between PGE(2) and COX2 in the biology of myeloid-derived suppressor cells. ...
Negative feedback in a system occurs when the system functions in such a way that the effects of a disturbance are counteracted over time, bringing the system back to its predisturbance state. In landscapes, an example of negative feedback occurs when deposition of coarse sediment takes place ...
Cell signaling systems that contain positive-feedback loops or double-negative feedback loops can, in principle, convert graded inputs into switch-like, irreversible responses. Systems of this sort are termed ‘bistable’. Recently, several groups have engineered artificial bistable systems into Escheri...
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...
Bistability is ubiquitous in biological systems. For example, bistability is found in many reaction networks that involve the control and execution of important biological functions, such as signaling processes. Positive feedback loops, composed of speci
to capture the mechanisms controlling microbial physiology we incorporated the mass specific rates of these processes in the model as previously45. It is important to highlight that a substantial fraction of CUE variation remains unexplained in the model, meaning that other important factors are not ...
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...
The term "plus" can also imply a benefit or an addition in non-mathematical contexts, such as "a plus point" meaning an advantage. Conversely, "positive" is widely used to describe optimistic attitudes, affirmative answers ("a positive response"), or conditions ("positive feedback"), reflect...
