Epigenetics to proteomics: from yeast to brain

Abstract

Brain is the most complex and least understood organ of the body. Recent research suggests that epigenetics of the brain may be behind the complex functions of this master organ. Yeast, the simplest eukaryote, had been the model for studying the complex physiology of higher eukaryotes, including humans. Current depth in understanding of mechanisms of gene regulation has been possible mainly because of the knowledge acquired by epigenetic studies on yeast while the research on the biochemistry and physiology of the brain has been tremendously benefitted by proteomic studies. The independent advances of research in both these fields are now converging. As the current understanding of epigenetics can be applied to understand the mysteries of normal brain function as well as various diseases, modern proteomic approaches can help find new therapeutic targets.
