Isogenic cells in a common environment present a large degree of heterogeneity in gene expression. Part of this variability is attributed to transcriptional bursting: the stochastic activation and inactivation of promoters that leads to the discontinuous p ...
Isogenic cells sharing a common environment present a large degree of heterogeneity in gene expression, and stochasticity inherent to transcription substantially participates in this cell-to-cell variability. Notably, a majority of mammalian genes are tran ...
The molecular clock has been conserved from cyanobacteria to mammals and is believed to align behavioral and biochemical processes with the diurnal cycle. This cellular mechanism has been an advantage to increase the fitness of organisms through the abilit ...
In mammals the circadian clock drives daily behavioural and physiological changes that resonate with environmental cues, which can be observed, for example, in the intricate timing of rest during the night and activity during the day in humans. The circadi ...
KAP1 is an enigmatic regulatory protein, first described some twenty years ago, shown to be involved in multiple and diverse cellular functions. Specifically, it mediates tasks critical to cell growth and differentiation, pluripotency, apoptosis, gene sile ...
Deposition of epigenetic marks is an important layer of the transcriptional control of retrotransposons, especially during early embryogenesis. Krüppel-associated box domain zinc finger proteins (KRAB-ZFPs) are one of the largest families of transcription ...
Transcription represents a key regulatory step in gene expression and transcription factors (TFs) are the key molecular players of this process. TFs inhibit or promote the assembly of the transcriptional machinery by binding DNA and several co-factors. Whe ...
In mammals, transcription was observed to occur predominantly in bursts, resulting from short and intense periods of gene transcription interspersed by longer silent periods. In order to elucidate the causes and the consequences of discontinuous transcript ...
Chromatin condensation plays an important role in the regulation of gene expression. Recently, it was shown that the transcriptional activation of Hoxd genes during vertebrate digit development involves modifications in 3D interactions within and around th ...
Background: Understanding the mechanisms by which transcription factors (TF) are recruited to their physiological target sites is crucial for understanding gene regulation. DNA sequence intrinsic features such as predicted binding affinity are often not ve ...
