Monomeric Bistability and the Role of Autoloops in Gene Regulation

WebThe repressilator is a genetic regulatory network consisting of at least one feedback loop with at least three genes, each expressing a protein that represses the next gene in the loop. In biological research, repressilators have been used to build cellular models and understand cell function. There are both artificial and naturally-occurring repressilators. Webwe ﬁrst present a model of the canonical GRN (the Hes1 protein) and show the e↵ect of varying the spatial location of gene and protein production sites on the oscillations. We then extend the approach to examine spatio-temporal models of synthetic gene regulatory networks e.g. n-gene repressilators and activator-repressor systems. 1 ... honeymoon white wineWebThe synthetic gene network implements an artificial differentiation process that changes the physicochemical properties of the agents.
