A surprising portion of both mammalian and Drosophila genomes are transcriptionally paused, undergoing initiation without elongation. We tested the hypothesis that transcriptional pausing is an obligate transition state between definitive activation …
Embryonic stem cell (ESC) differentiation is an excellent model to study chromatin changes at developmentally regulated loci. Differentiating mouse and human ESCs increase genome-wide acetylation (euchromatic) and tri-methylation (heterochromatic) of …
Understanding pathways controlling cardiac development may offer insights that are useful for stem cell-based cardiac repair. Developmental studies indicate that the Wnt/beta-catenin pathway negatively regulates cardiac differentiation, whereas …
