The Claim
In human hepatoma HepG2 cells, sulforaphane induces increased glutathione synthesis, redirected glutamine and glucose flux, and enhanced methylation, and these metabolic effects are entirely dependent on NRF2, as CRISPR-Cas9 knockout of NRF2 abolishes these changes.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In human liver cancer cells, sulforaphane alters metabolic pathways including glutathione production and nutrient usage, and these changes require the presence of the NRF2 protein; removing NRF2 eliminates all these metabolic effects.
See the scientific wording
In human hepatoma HepG2 cells, the metabolic effects of sulforaphane—including increased glutathione synthesis, redirected glutamine and glucose flux, and enhanced methylation—are entirely dependent on NRF2, as demonstrated by CRISPR-Cas9 knockout of NRF2 abolishing these changes.
When sulforaphane enters liver cells, it disables a brake protein that normally holds back a master regulator called NRF2. Once freed, NRF2 turns on genes that increase the production of glutathione, a key antioxidant, by pulling in more raw materials like cysteine and glutamate. It also shifts sugar use away from energy production and toward generating a molecule called NADPH, which keeps glutathione active. At the same time, NRF2 redirects amino acid use to boost methylation reactions by increasing methionine and its active form, while reducing the production of other amino acids like serine and glycine that would otherwise be used for different purposes.
What the research says
1 studyWhen scientists removed a protein called NRF2 from liver cells, sulforaphane could no longer make the cells produce more glutathione or change how they use sugar and other nutrients—proving NRF2 is needed for all these changes.
