The Claim

In human hepatoma HepG2 cells exposed to high glucose (25 mM), sulforaphane (10 μM) increases flux through the pentose phosphate pathway by upregulating glucose-6-phosphate dehydrogenase and transketolase, which enhances NADPH production to support glutathione regeneration, while simultaneously reducing the expression of glycolytic genes and lactate production.

How it works
1 study reviewed
In plain English

In liver cancer cells grown under high sugar conditions, sulforaphane increases activity in the pentose phosphate pathway by boosting specific enzymes, leading to higher NADPH levels and more glutathione production, while decreasing the expression of genes involved in glycolysis and reducing lactate output.

See the scientific wording

In human hepatoma HepG2 cells under high glucose (25 mM), sulforaphane (10 μM) increases flux through the pentose phosphate pathway (PPP) by upregulating G6PD and TKT, enhancing NADPH production to support glutathione regeneration, while reducing glycolytic gene expression and lactate production.

Why this might work

Sulforaphane triggers a switch in liver cells from making energy from sugar to making protective antioxidants. It activates a master regulator that turns on genes for enzymes that pull sugar into a special pathway to generate NADPH, a molecule that recharges antioxidants. This same regulator also blocks sugar from being turned into lactate and increases the import of raw materials needed to build the main antioxidant, allowing the cell to neutralize damage caused by excess sugar.

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

    Sulforaphane, a compound in broccoli, tells liver cells under high sugar to stop making energy from sugar and instead use it to make antioxidants that protect the cell. This helps the cell fight damage caused by too much sugar.
