Coherent vs incoherent feed-forward loops
WebThere are eight possible three-node FFLs as each of the three arrows can be either repression or activation, which can be classified into coherent or incoherent FFLs. Coherent FFLs have the same sign for both the paths … WebCoherent feed-forward loops exist extensively in realistic biological regulatory systems, and are common signaling motifs. Here, we study the characteristics and the propagation …

WebConsider the two feed-forward loops below containing three transcription regulators A, B, and C, where A receives the input signal and C generates the output. In the so-called coherent loop (left), A activates C both directly and indirectly, whereas in an incoherent loop (right), A activates C via one route and inactivates it via the other. heather cucchetti doWebDec 11, 2009 · Summary. Many sensory systems (e.g., vision and hearing) show a response that is proportional to the fold-change in the stimulus relative to the background, a feature related to Weber's Law. Recent experiments suggest such a fold-change detection feature in signaling systems in cells: a response that depends on the fold-change in the input ... movie action clickerWebIn a coherent FFL, the regulatory paths have the same effects on the target (either activation or repression) (Figure 1b), whereas in an incoherent loop the expression of the target is controlled by two reverse paths (Figure 1c). Thus, coherent and incoherent FFLs could lead to different effects on gene regulation. heather cuddyWebMar 10, 2006 · One of the most common network motifs is the incoherent type-1 feed-forward loop (I1-FFL), in which a transcription activator activates a gene directly, and also activates a repressor of the gene.
