Summary of Meeting
Many chromatin modifications and structures are surprisingly dynamic, yet are involved in initiating and heritably maintaining distinct gene expression patterns that direct and preserve cellular identities. The molecules that target and regulate these modifications and how they influence—and may be influenced by—higher-order chromatin structures, nuclear organization, and various nuclear processes, are areas of intense interest and excitement. This meeting will examine the latest discoveries surrounding the molecular basis of chromatin modifications and explore their connections to various biological processes and epigenetic phenomena such as dosage compensation, imprinting, heterochromatin formation and gene expression in differentiation, development and disease. The goal is to promote a more integrated picture of the molecular interrelationships between chromatin structure and function that exercise the hidden regulatory information in the genomes of complex organisms.
