The Claim

Genetic deletion or pharmacological inhibition of CaMKK2 in adult mouse skeletal muscle does not impair contraction-stimulated AMPK phosphorylation at Thr172 or glucose uptake, indicating that CaMKK2 is not required for these processes under normal physiological conditions.

Source: CaMKK2 is not involved in contraction-stimulated AMPK activation and glucose uptake in skeletal muscle

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 adult mice, blocking or removing the CaMKK2 protein does not reduce the activation of AMPK or the uptake of glucose in skeletal muscle during muscle contraction.

See the scientific wording

In adult mouse skeletal muscle, genetic deletion or pharmacological inhibition of CaMKK2 does not impair contraction-stimulated AMPK phosphorylation at Thr172 or glucose uptake, indicating that CaMKK2 is not required for these processes under normal physiological conditions.

Why this might work

When muscle contracts, it uses up energy, which causes a rise in AMP and ADP levels. This change triggers LKB1 to add a phosphate group to AMPK at a specific spot, turning it on. Activated AMPK then signals the muscle to take in more sugar from the blood to make more energy, all without needing CaMKK2.

  1. Study: CaMKK2 is not involved in contraction-stimulated AMPK activation and glucose uptake in skeletal muscle

    When scientists removed or blocked the CaMKK2 protein in mouse muscles, the muscles still activated AMPK and took up sugar normally during contraction — meaning CaMKK2 isn’t needed for this process. Even fake drugs that couldn’t block CaMKK2 still stopped sugar uptake, proving earlier results were mistakes.
