Glyceryl triacetate, an oral acetate precursor: molecular mechanisms & dependencies

How nutrients influence it

Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.

Human evidence only

How nutrients reach it in more than one step

Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does

Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.

Recorded relationships

What it acts on

A single oral dose of glyceryl triacetate increased the acetylation state of brain histone H4 at lysine 8 at 2 and 4 hours, histone H4 at lysine 16 at 4 and 24 hours, and histone H3 at lysine 9 at 4 hours, with no changes in other forms of brain or liver H3 and H4 acetylation state at any time measured.

Complete structured claim and evidence
Acetate supplementation had no effect on histone acetyltransferase activity in brain extracts but significantly inhibited histone deacetylase activity twofold at 2 and 4 hours after treatment and decreased HDAC 2 levels at 4 hours, leading the authors to conclude that acetyl-CoA derived from acetate supplementation increases brain histone acetylation state by reducing deacetylase activity and expression.

The marks accumulated because they were being removed more slowly, not because more were being added.
