The Claim

In mice, the deletion of either MPC2 or ALT2 individually in the liver does not impair endurance exercise performance or post-exercise glucose homeostasis, suggesting that compensatory metabolic pathways are sufficient to maintain gluconeogenic capacity when only one mitochondrial substrate entry route is disrupted.

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 mice, turning off one of two specific liver genes doesn’t hurt their stamina or blood sugar control after exercise, because their bodies can use backup systems to keep making glucose.

See the scientific wording

In mice, deletion of either MPC2 or ALT2 alone in the liver does not impair endurance exercise performance or post-exercise glucose homeostasis, indicating that compensatory metabolic pathways can maintain gluconeogenic capacity when only one mitochondrial substrate entry route is disrupted.

What the research says

1 study
  1. Study: Disruption of Hepatic Mitochondrial Pyruvate and Amino Acid Metabolism Impairs Gluconeogenesis and Endurance Exercise Capacity in Mice

    The study found that mice could still exercise normally and maintain blood sugar after losing one of two key liver proteins, because the body used backup systems—just like the claim says.
