Metaboloepigenetics: the Emerging Network in Stem Cell Homeostasis Regulation

Area of Science:

• Biochemistry
• Molecular Biology
• Cell Biology

Background:

• Epigenetics provides regulatory information beyond DNA sequence, enabling cellular decision-making.
• Metabolites are increasingly linked to epigenetic chromatin-modifying enzymes, connecting cellular metabolism to gene expression and cell fate.
• Epigenetic information can be transient or stable, and transmitted to daughter cells or across generations.

Purpose of the Study:

• To review the connections between metabolism and epigenetic regulation in stem cell differentiation and self-renewal.
• To explore how altered metabolism and nutrition contribute to disease through epigenetic modifications.
• To discuss the interplay of the circadian clock, metabolic regulation, and epigenetics in stem cell homeostasis.

Main Methods:

• Literature review of recent discoveries and pertinent studies.
• Synthesis of information on metabolite-epigenetic enzyme interactions.
• Analysis of research on nutrition, disease, and epigenetic mechanisms.

Main Results:

• Metabolic state directly influences epigenetic regulation of stem cell processes.
• Altered metabolism and nutrition are implicated in disease development via epigenetic changes.
• The circadian clock, metabolic regulation, and epigenetics are interconnected, impacting stem cell homeostasis.

Conclusions:

• Metabolism and epigenetics are tightly linked, governing stem cell behavior and fate.
• Nutritional status and metabolic dysregulation can drive disease through epigenetic alterations.
• Understanding these links is crucial for stem cell biology, disease prevention, and therapeutic strategies.
