Metabolic-associated Fatty Liver Disease Regulation through Nutri Epigenetic Methylation

Area of Science:

• Hepatology and Epigenetics
• Nutritional Science
• Molecular Biology

Background:

• Metabolically associated fatty liver disease (MAFLD), previously nonalcoholic fatty liver disease, is a prevalent global liver condition and a leading cause for liver transplantation.
• MAFLD is characterized by over 5% lipid accumulation in hepatocytes, excluding other liver diseases.
• Disease progression is influenced by factors including inflammation, oxidative stress, gut-liver axis alterations, dysbiosis, and epigenetic modifications.

Purpose of the Study:

• To explore the role of epigenetics in the development and progression of MAFLD.
• To investigate the connection between nutriepigenomics, specifically one-carbon metabolism and its associated micronutrients, and MAFLD.
• To highlight the potential of epigenetic modifiers as therapeutic targets for MAFLD.

Main Methods:

• Review of existing literature on epigenetics and MAFLD.
• Analysis of the role of nutriepigenomics and micronutrients (methionine, folate, choline) in epigenetic regulation.
• Examination of epigenetic mechanisms like DNA methylation and histone modifications in the context of MAFLD.

Main Results:

• Epigenetic alterations are significantly associated with various diseases, including MAFLD.
• Micronutrients involved in one-carbon metabolism act as methyl group donors, influencing epigenetic states.
• Deficiency in these key micronutrients is linked to an increased risk of developing MAFLD.

Conclusions:

• Epigenetic modifications play a crucial role in MAFLD pathogenesis.
• Nutrient-driven epigenetic regulation, particularly via one-carbon metabolism, is a key factor in MAFLD.
• Targeting epigenetic modifiers offers a promising avenue for novel MAFLD therapies.
