How Mitochondrial MPC Transport Blocks Fatal Heart Failure
Dr. Jared Rutter explains the discovery of MPC1 and MPC2, and how blocking pyruvate transport causes lethal heart failure.
How Mitochondria Control Your Metabolism | Dr. Jared Rutter
With Andrew Huberman, Dr. Jared Rutter · Sunday, September 13, 2026
Dr. Jared Rutter, a professor of biochemistry and HHMI investigator, joins Andrew Huberman to explain the nuanced biology of cellular metabolism and mitochondria. They discuss how individual cells balance energy production against biomass generation, the discovery of the mitochondrial pyruvate carrier (MPC), and how metabolic dysregulation drives diseases such as heart failure, cancer, and accelerated aging.
Key takeaways
- Jared Rutter identified MPC1 and MPC2, solving a 60-year mystery around how pyruvate enters mitochondria across yeast, fruit flies, and mammals. Read more →
- Dr. Jared Rutter explains that pyruvate inside cells faces two main paths: oxidation inside mitochondria or conversion into lactate. Read more →
- Dr. Jared Rutter explains that flooding mitochondria with more chemical energy than they can convert into ATP pushes them into an unstable, electron-dense state. Read more →
- Glycolysis ends at a single chemical junction: pyruvate. Read more →
- Human metabolism is the collective output of roughly 30 trillion individual cells, rather than a single unified internal furnace. Read more →
- Otto Warburg's 1920s hypothesis claimed broken mitochondria cause cancer, but modern biochemistry shows tumor mitochondria actively redirect resources into biomass rather than ATP. Read more →

Why Lactate Is Cellular Fuel, Not Toxic Waste
Dr. Jared Rutter explains how lactate preserves carbon for biomass, powers the brain and heart, and signals neuroplasticity through BDNF.
Dr. Jared Rutter on How Excess Energy Overpowers Mitochondria
Dr. Jared Rutter explains how excess cellular fuel overpowers mitochondria, generating reactive oxygen species that damage DNA and accelerate aging.
How Cells Choose Between Energy and Biomass
Dr. Jared Rutter explains how cells decide whether to burn pyruvate for ATP or build biomass, and why this resource split dictates health.
Jared Rutter on Why Metabolism Is 30 Trillion Cells, Not One Furnace
Dr. Jared Rutter explains how 30 trillion cells adapt their mitochondria to balance ATP production against biomass growth across tissues.
Why Cancer Cells Thrive and How Multi-Drug Cocktails Stop Them
Dr. Jared Rutter explains why cancer mitochondria aren't broken, how tumors beat single drugs, and why oncology must adopt HIV-style multi-drug cocktails.
