Abstract

Purpose

We have investigated the epigenetic regulation by dietary fatty acids of Vegfb levels in rats’ white adipose tissue and 3T3-L1 cells.

Methods

A group of rats were assigned to three diets, each one with a different composition of saturated, monounsaturated and polyunsaturated fatty acids. Samples of white adipose tissues were taken for the methylation and expression studies. Additionally, 3T3-L1 cells were treated with palmitic, oleic, and linoleic fatty acids. After treatment, cells were harvested and genetic material was extracted for the analysis of Vegfb levels.

Results

We report evidence of changes in the methylation levels of the CpG island at the Vegfb promoter and in the Vegfb expression levels in vivo and in vitro by dietary fatty acid, with the main contribution of the linoleic fatty acid. Vegfb promoter methylation levels were closely related to the Vegfb gene expression.

Conclusion

According to our results, the regulation of Vegfb gene expression by dietary fatty acids may be mediated, at least in part, by epigenetic modifications on Vegfb promoter methylation. Considering the deep association between angiogenesis and tissue growth, we suggest the nutriepigenetic regulation of Vegfb as a key target in the control of the adipose tissue expansion.

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
