2.4.1 Negative feedback Glucose metabolism provides us with examples of such negative feedback. For instance, in a normal individual, an increase in blood glucose concentration (variable X), brought about by the ingestion of the carbohydrate component of a meal, causes an increase in the secreti...

Using two families of genetic oscillators as model examples, we show that the loop gain required for oscillations is minimum when all elements in the loop have the same time constant. On the contrary, we show that homeostasis is ensured if a single element is considerably slower than the ...
However, negative feedback loop motifs are unavailable for thiol chemistry. Here, we develop a negative feedback loop based on the selenocarbonates. In this system, thiols induce the release of aromatic selenols that catalyze the oxidation of thiols by organic peroxides. This negative feedback ...
Negative regulatory feedback loopCancer stem-like cellsNasopharyngeal carcinomaOverexpression of the c-Myc oncogene has been implicated in cancer stem cell - like (CSC) phenotypes and epithelial-to-mesenchymal transition (EMT) in cancer. However, the underlying molecular mechanism by which c-Myc ...
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.
Therefore, MYC2 and MTB proteins form an autoregulatory negative feedback circuit to 43 terminate JA signaling in a highly organized manner. We provide examples demonstrating that gene 44 editing tools such as CRISPR/Cas9 open up new avenues to exploit MTB genes for crop protection. 45 46 ...
In addition, individual examples of genes that have a FOXP1 ChIP-seq peak within 10 kb of the TSS that are differentially expressed by FOXP1 depletion are shown. Stimulation of FOXO3(A3)–ER increases the expression of p27Kip1, but this is not affected by FOXP1 depletion (lower panel)....
