Regulation of Primary Response Genes

Primary response genes (PRGs) are a set of genes that are induced in response to both cell-extrinsic and cell-intrinsic signals and do not require de novo protein synthesis for their expression. These first responders in the waves of transcription of signal-responsive genes play pivotal roles in a wide range of biological responses, including neuronal survival and plasticity, cardiac stress response, innate and adaptive immune responses, glucose metabolism, and oncogeneic transformation. Here we bring together recent advances and our current understanding of the signal-induced transcriptional and epigenetic regulation of PRGs.
