The Claim

Thyroid hormone stimulates fatty acid oxidation in human and mouse cells through the CaMKKβ-AMPK pathway, and inhibition of CaMKKβ via STO-609 or siRNA knockdown abolishes the T3-induced increase in fatty acid oxidation.

Source: Thyroid hormone activates adenosine 5'-monophosphate-activated protein kinase via intracellular calcium mobilization and activation of calcium/calmodulin-dependent protein kinase kinase-beta.

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

Thyroid hormone increases the breakdown of fatty acids in human and mouse cells by activating the CaMKKβ-AMPK signaling pathway, and blocking CaMKKβ prevents this increase.

See the scientific wording

Thyroid hormone stimulates fatty acid oxidation in human and mouse cells through the CaMKKβ-AMPK pathway, as inhibition of CaMKKβ with STO-609 or siRNA knockdown of CaMKKβ abolishes the T3-induced increase in fatty acid oxidation.

Why this might work

Thyroid hormone triggers a surge of calcium inside cells, which turns on an enzyme called CaMKKβ. This enzyme then activates another enzyme called AMPK, which shuts down a blocker of fat burning. As a result, fats are pulled into mitochondria and burned for energy.

What the research says

1 study

  1. Study: Thyroid hormone activates adenosine 5'-monophosphate-activated protein kinase via intracellular calcium mobilization and activation of calcium/calmodulin-dependent protein kinase kinase-beta.

    The study shows that when you block a specific enzyme called CaMKKβ, thyroid hormone can’t make cells burn fat anymore — proving this enzyme is needed for the hormone to work.
