Abstract Lipids are crucial for various cellular functions. Besides the storage of energy equivalents, these include forming membrane bilayers and serving as signaling molecules. While significant progress has been made in comprehension molecular biology lipids, their functions cell nucleus remain poorly understood. The main role eukaryotic is to provide an environment regulation chromatin which a complex DNA, histones, associated proteins. Recent studies suggest that nuclear lipids play epigenetics. Here, we discuss experimental methods lipid‐chromatin research, including biophysical, structural, approaches, pointing out strengths weaknesses. We take view have far more widespread impact on than currently acknowledged. This gap mostly due existing challenges study biology. Several new, interdisciplinary approaches discussed could aid elucidating roles gene expression.

Aging is a fundamental driver of numerous life-threatening diseases, significantly compromising cellular structures and functions, including the integrity nucleus. A consistent feature aging across diverse species progressive accumulation lipid droplets (nLDs) within nuclear compartment, which disrupts architecture functionality. Notably, accompanied by marked increase in nLD at envelope. Interventions known to extend lifespan, such as caloric restriction reduced insulin signaling, reduce both rate size nLDs. The triglyceride lipase ATGL-1, localizes envelope, plays critical role limiting buildup maintaining balance, especially long-lived mutant worms. These findings establish excessive deposition key hallmark aging, with profound implications for processes chromatin organization, DNA repair, gene regulation. In addition, ATGL-1 emerges promising therapeutic target preserving health, extending organismal healthspan, combating age-related disorders driven dysregulation.
