Metabolism-driven chromatin dynamics: Molecular principles and technological advances

Area of Science:

• Molecular Biology
• Metabolism
• Epigenetics

Background:

• Cells adapt to environmental changes by integrating metabolic signals into molecular processes like transcription.
• Chromatin, the genome's structural framework, functions as a sensor and regulator for intracellular metabolite levels.

Purpose of the Study:

• To review the growing list of chromatin-associated metabolites and their diverse origins.
• To discuss mechanisms by which metabolic enzymes modify chromatin structure and function.
• To explore technologies for studying the epigenome-metabolome interplay.

Main Methods:

• Literature review of recent advances in epigenetics and metabolism research.
• Analysis of mechanisms linking metabolic enzymes to chromatin regulation.
• Discussion of emerging technologies for epigenome-metabolome studies.

Main Results:

• A diverse array of metabolites are associated with chromatin.
• Metabolic enzymes actively shape chromatin structure and epigenetic modifications.
• Specificity in chromatin regulation emerges despite broad metabolite effects.

Conclusions:

• Metabolites are integral to the chromatin regulatory network.
• Understanding the epigenome-metabolome interplay has profound implications for epigenome evolution and function.
• This interplay offers potential avenues for therapeutic targeting of the epigenome.
