The Claim

Insulin and niacin do not significantly activate the ERK1/2 MAP kinase pathway in human subcutaneous adipose tissue under the conditions tested, suggesting this pathway is not a major mediator of free fatty acid uptake in vivo.

How it works
1 study reviewed
In plain English

In human fat tissue, neither insulin nor niacin strongly triggers the ERK1/2 signaling pathway under the conditions studied, indicating that this pathway likely does not play a major role in how free fatty acids are taken up by fat cells in the body.

See the scientific wording

Insulin and niacin do not significantly activate the ERK1/2 MAP kinase pathway in human subcutaneous adipose tissue under the conditions tested, suggesting this pathway is not a major mediator of free fatty acid uptake in vivo.

Why this might work

When niacin or insulin is given, they both stop fat cells from releasing fatty acids into the blood. This lets more fatty acids stay inside the fat tissue, even though only insulin turns on a specific signaling pathway called ERK1/2. Since both drugs cause the same amount of fat storage, the ERK1/2 pathway isn’t needed for this to happen.

  1. Study: Adipose Tissue Free Fatty Acid Storage In Vivo: Effects of Insulin Versus Niacin as a Control for Suppression of Lipolysis

    The study found that insulin and niacin both led to the same amount of fat storage in fat tissue, even though they work differently in the body. Since niacin doesn’t activate a certain signaling pathway (ERK1/2), but insulin does, and both had the same effect, this suggests that pathway isn’t important for fat storage.
