The Claim
Perturbation of the PGE2-EP4 signaling pathway is associated with a state of metabolically healthy obesity in humans.
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.
Changes in the PGE2-EP4 signaling pathway occur alongside a condition in which individuals have excess body fat but do not show typical metabolic problems like insulin resistance or high blood pressure.
See the scientific wording
Perturbation of the PGE2-EP4 signaling pathway is associated with a state of 'metabolically healthy obesity' in humans.
When fat cells are exposed to insulin after eating, they produce a signaling molecule that binds to a specific receptor on their surface. This keeps fat breakdown active even when the body should be storing fat, and over time it causes scar tissue to build up inside fat deposits. The scar tissue prevents fat cells from expanding properly, so excess fat spills into the liver and muscles instead. This fat in the wrong places disrupts how the body responds to insulin, leading to metabolic disease.
What the research says
1 studyWhen a specific body signal (PGE2-EP4) is turned off, some very overweight people don’t get diabetes or fatty liver disease — their bodies stay healthy despite the weight. This study shows that breaking this signal might protect them from metabolic problems.
