WebFeb 21, 2024 · This work constructs two different functional and modular incoherent type 1 feedforward loop circuits in a cell-free transcription-translation system and in cells, and demonstrates that these feedforward loops show dynamic response and pulse-like behavior both in vitro and in vivo.

In physiology, feed-forward control is exemplified by the normal anticipatory regulation of heartbeat in advance of actual physical exertion by the central autonomic network. Feed-forward control can be likened to learned anticipatory responses to known cues (predictive coding). Feedback regulation of the heartbeat provides further adaptiveness to the running eventualities of physical exertion. Feedforward systems are also found in biological control of other variables by … WebWe show here that the number of feedback loops in a network, as well as the eigenvalues of associated matrices, is determined by a structural property called trophic coherence, a measure of how neatly nodes fall into distinct levels. ...
