Feedback inhibition (in biology) is defined as the process in which the end product of a reaction inhibits or controls the action of the enzyme that helped produce it. In other words, the end products formed in the reaction actually get enzymes to slow down or stop making new products alto...
When the concentration of D gets too high in comparison to substrate A (in this instance), it starts to inhibit the action of enzyme 1. Noticethat D will bond with the allosteric site on enzyme 1. Hence, end product inhibition or negative feedback inhibition is non-competitive. What is a...
The stimulatory limb of the HPA axis (CRH, vasopressin, and ACTH) is kept in check by continuous feedback inhibition by circulating glucocorticoid hormones. Thus, it has been hypothesized that the intensity of this negative feedback action may be an underlying factor in the sexually dimorphic sec...
CBL1 did not lead to detectable activation of AMT1;1 activity (Additional file1: Figure S2). The inhibition of AMT1;1 activity was not due to effects of CIPK15 co-expression on AMT1;1 levels as shown by protein gel blots (Additional file1: Figure S3). Because we focused...
A systems- biology analysis of feedback inhibition in the Sho1 osmotic-stress-response pathway. Curr Biol. 2007; 17:659-667. [PubMed: 17363249]A systems-biology analysis of feedback inhibition in the Sho1 osmotic-stress-response pathway - Hao, Behar, et al. - 2007...
We also tested the hypothesis about product inhibition (Fig. 6d). These experiments showed that the rate of oxidation is significantly suppressed by a high (>10 mM) concentration of 9. Overall, the fitting of the presented experiments provided five data points with Vmax and KM values (Fig....
Indeed, induction of EMT led to an increase in GABARAPL1 levels through the activation of the SMAD signaling pathway, and then GABARAPL1 induced the autophagy-selective degradation of SMAD proteins, leading to EMT inhibition. Keywords: autophagy; ATG8; GABARAPL1; cancer; EMT; SMAD ...
By proteomics analysis of conditioned media from cells with constitutive mTORC1 activity, Yu and colleagues identify IGF binding protein 5 (IGFBP5) as a protein that is induced by mTORC1 through HIF1 and that blocks IGF-1 signalling. The PI(3)K–Akt–mTO

intramotoneuronalresponses evokedby the stimulation of several cutaneous andmuscle afferentswere quantified. This was done 4 weeks after the lesion for the two groups so that plasticity induced by time after the lesion was the same. It was found that group Ib inhibition was significantly decreased,...
