Plasticity of hormonal response permits rapid gene expression reprogramming

Gene expression is the process of converting the genetic information encoded in DNA into a final gene product such as a protein or any of several types of RNA.Scientists have long thought that the gene programs regulated by different physiological processes throughout the body are robustly pre-determined and relatively fixed for every specialized cell. But a new study by researchers from the University of California, San Diego School of Medicine reveals the unsuspected plasticity of some of these gene expression programs….
