Abstract
Recent studies in yeast reveal an intricate interplay between nuclear envelope (NE) architecture and lipid metabolism, and between lipid signaling and both epigenome and genome integrity. In this review, we highlight the reciprocal connection between lipids and histone modifications, which enable metabolic reprogramming in response to nutrients. The endoplasmic reticulum (ER)-NE regulates the compartmentalization and temporal availability of epigenetic metabolites and its lipid composition also impacts nuclear processes, such as transcriptional silencing and the DNA damage response (DDR). We also discuss recent work providing mechanistic insight into lipid droplet (LD) formation and sterols in the nucleus, and the collective data showing Opi1 as a central factor in both membrane sensing and transcriptional regulation of lipid-chromatin interrelated processes.
期刊介绍：
Trends in Cell Biology stands as a prominent review journal in molecular and cell biology. Monthly review articles track the current breadth and depth of research in cell biology, reporting on emerging developments and integrating various methods, disciplines, and principles. Beyond Reviews, the journal features Opinion articles that follow trends, offer innovative ideas, and provide insights into the implications of new developments, suggesting future directions. All articles are commissioned from leading scientists and undergo rigorous peer-review to ensure balance and accuracy.
