A genome-wide CRISPR screen identifies BRD4 as a regulator of cardiomyocyte differentiation - Nature Cardiovascular Research

AbstractHuman induced pluripotent stem cell (hiPSC) to cardiomyocyte (CM) differentiation has reshaped approaches to studying cardiac development and disease. In this study, we employed a genome-wide CRISPR screen in a hiPSC to CM differentiation system and reveal here that BRD4, a member of the bromodomain and extraterminal (BET) family, regulates CM differentiation.
Single-cell multimodal analyses reveal epigenomic and transcriptomic basis for birth defects in maternal diabetes - Nature Cardiovascular Research

Nov 29, 2023 | nature.com | Angelo Pelonero |Lin Ye |Michael Alexanian |Frances Koback |Casey A. Gifford

AbstractMaternal diabetes mellitus is among the most frequent environmental contributors to congenital birth defects, including heart defects and craniofacial anomalies, yet the cell types affected and mechanisms of disruption are largely unknown. Here, using multimodal single-cell analyses, we show that maternal diabetes affects the epigenomic landscape of specific subsets of cardiac and craniofacial progenitors during embryogenesis.
