The Claim

Thyroid hormone (T3) rapidly activates AMP-activated protein kinase (AMPK) in human and mouse cell lines through intracellular calcium mobilization and calcium/calmodulin-dependent protein kinase kinase-beta (CaMKKβ), leading to increased phosphorylation of acetyl-CoA carboxylase and enhanced fatty acid oxidation, independent of transcriptional mechanisms.

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

How it works
1 study reviewed
In plain English

Thyroid hormone T3 triggers a biochemical cascade in human and mouse cells that activates AMPK, increases phosphorylation of acetyl-CoA carboxylase, and boosts fatty acid oxidation without involving gene expression changes.

See the scientific wording

Thyroid hormone (T3) rapidly activates AMP-activated protein kinase (AMPK) in human and mouse cell lines through intracellular calcium mobilization and calcium/calmodulin-dependent protein kinase kinase-beta (CaMKKβ), leading to increased phosphorylation of acetyl-CoA carboxylase and enhanced fatty acid oxidation, independent of transcriptional mechanisms.

Why this might work

Thyroid hormone binds to its receptor on or inside the cell, causing calcium to be released from internal stores. This calcium binds to a protein that activates another enzyme, which then turns on AMPK. Activated AMPK shuts down a key enzyme that blocks fat burning, allowing fatty acids to enter mitochondria and be burned for energy.

  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.

    This study shows that thyroid hormone quickly turns on a cellular energy switch (AMPK) by first raising calcium levels inside cells, which then activates a protein (CaMKKβ) that flips the switch — all without changing any genes. This helps cells burn fat faster for energy.
