The Claim

In human hepatoma HepG2 cells exposed to high glucose (25 mM), sulforaphane (10 μM) increases the SAM:SAH ratio through modulation of methionine cycle metabolites and upregulation of BHMT2, and this effect is dependent on NRF2.

How it works
1 study reviewed
In plain English

In liver cancer cells grown in high glucose, sulforaphane increases the ratio of SAM to SAH by altering methionine cycle metabolites and increasing BHMT2 levels, and this change requires NRF2.

See the scientific wording

In human hepatoma HepG2 cells under high glucose (25 mM), sulforaphane (10 μM) increases the SAM:SAH ratio by modulating methionine cycle metabolites and upregulating BHMT2, suggesting enhanced cellular methylation capacity, which is dependent on NRF2.

Why this might work

Sulforaphane triggers a cellular defense system that reprograms how liver cells use sugar and amino acids. It shifts resources away from making energy and instead channels them into producing molecules that add methyl groups to DNA and proteins. This happens by increasing the supply of methionine, the building block of the main methyl donor, and by activating an enzyme that recycles a waste product back into methionine. The entire process depends on a master regulator that turns on these changes when the cell is under stress from too much sugar.

  1. Study: Sulforaphane rewires central metabolism to support antioxidant response and achieve glucose homeostasis

    Sulforaphane, a compound in broccoli, helps liver cells handle too much sugar by turning on a cellular defense system (NRF2) that boosts the production of molecules needed for healthy chemical reactions, including methylation — even if it didn’t measure every single detail mentioned in the claim.
