Nuclear Receptor Coregulators in Metabolism and Disease

Within the past two decades, coregulators have emerged as essential chromatin components of metabolic signaling by nuclear receptors and additional metabolite-sensing transcription factors. Intriguingly, coregulators themselves are efficient sensors and effectors of metabolic stimuli that modulate gene expression at different levels, often via post-translational modifications of histones or other factors. There is already evidence that alterations of expression or function of coregulators contributes to metabolic disease by propagating disease-specific epigenomes linked to the dysregulation of transcription and downstream pathways. In this chapter we review the current progress made in understanding the role of coregulators in metabolic pathways, with a particular emphasis on their study in vivo and in the context of metabolic disease.
