The Claim

In patient-derived diffuse intrinsic pontine glioma (DIPG) cell lines, the combination of phenformin (0.625 mM) and dichloroacetate (DCA, 25 mM) reduces intracellular lactate levels compared to phenformin alone, suppresses mitochondrial oxidative phosphorylation and glycolytic flux, and induces synergistic ATP depletion, oxidative stress, DNA damage, and apoptosis.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

In laboratory-grown brain tumor cells derived from patients, a combination of two drugs—phenformin and dichloroacetate—lowers lactate levels, reduces energy production through mitochondria and glycolysis, and triggers cell death through ATP loss, oxidative stress, DNA damage, and apoptosis.

See the scientific wording

In patient-derived diffuse intrinsic pontine glioma (DIPG) cell lines, the combination of phenformin (0.625 mM) and dichloroacetate (DCA, 25 mM) reduces intracellular lactate levels compared to phenformin alone, suppresses mitochondrial oxidative phosphorylation and glycolytic flux, and induces synergistic ATP depletion, oxidative stress, DNA damage, and apoptosis, suggesting a metabolic vulnerability that may enhance tumor cell death.

Why this might work

One drug blocks the cell's main energy factory, and the other forces fuel into that same broken factory. This causes the cell to run out of energy, produce toxic waste, and break its own DNA. The cell tries to fix the damage but cannot because it lacks the tools and energy, so it dies.

  1. Study: Metabolic reprogramming in diffuse intrinsic pontine gliomas (DIPG): dual inhibition of mitochondrial oxidative phosphorylation and lactate metabolism to enhance anti-tumor and radiosensitizing effects in DIPG cells

    In lab-grown brain tumor cells, mixing two drugs—phenformin and DCA—made the cells run out of energy, produce less waste acid, and die more than either drug alone. This supports the idea that the combo attacks the tumor’s energy system effectively.
