Incoherent feedback loop
WebRecent work has shown that the incoherent feed-forward loop (IFFL) can provide a remarkably simple mechanism for gene dosage compensation. Here, we will explore two different IFFL designs that use either … WebFeedback loops comprising two transcription interactions. Developmental transcription networks often use positive-feedback loops that are made up of two transcription factors …

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. WebJan 4, 2024 · Specifically, we propose that an incoherent feedback loop mechanism, besides high redundancy, mediates robustness of expression of broadly expressed genes, and we show how redundancy may be a consequence of motif turnover in regulatory sequences, instead of the result of natural selection favouring robustness. Methods
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. ... Meanwhile, the networks linked to metabolism are significantly incoherent (q/q̃ > 1) and have mean trophic ... WebNov 19, 2024 · Incoherent feed-forward signaling of a positive feedback loop with distinct regulatory thresholds of the two arms of the feed-forward loop are the key requirements for such emergent behaviors. Our calculations show that the specific types of atypical bistable responses depend on the logic gate configuration of the signals.
WebJul 20, 2012 · Such feedback loops are built into the way that natural systems work, and they affect all life forms at all levels. Natural selection, as one example, is based on continual … WebJul 10, 2024 · In particular, we showed that an incoherent feedforward loop Type 1 (I1-FFL), from within a gene regulatory circuit, can be finely-tuned for perfect adaptation after a …
