The Claim
12/15-lipoxygenase deficiency in mice reduces hepatic steatosis and inflammation to a similar extent as lowering the dietary omega-6 to omega-3 ratio, and both interventions reduce plasma oxidized arachidonic acid metabolites, indicating that 12/15-lipoxygenase is a key enzymatic mediator of omega-6 fatty acid-induced liver damage.
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.
In mice, removing the enzyme 12/15-lipoxygenase reduces fat accumulation and inflammation in the liver, just as reducing dietary omega-6 relative to omega-3 fatty acids does. Both approaches lower levels of oxidized arachidonic acid metabolites in the blood, showing that this enzyme plays a central role in liver damage caused by omega-6 fatty acids.
See the scientific wording
In mice, 12/15-lipoxygenase deficiency reduces hepatic steatosis and inflammation similarly to lowering dietary omega-6 to omega-3 ratio, and both interventions reduce plasma oxidized arachidonic acid metabolites, suggesting that 12/15-lipoxygenase is a key enzymatic mediator of omega-6 fatty acid-induced liver damage.
When omega-6 fats are abundant, the enzyme 12/15-lipoxygenase converts arachidonic acid into inflammatory molecules that activate liver immune cells, trigger the release of signaling proteins that attract immune cells, and increase fat production in liver cells, leading to fat buildup and tissue damage. Removing this enzyme or reducing omega-6 fats stops this chain, preventing liver damage.
What the research says
1 studyIn mice, removing the 12/15-lipoxygenase enzyme or eating less omega-6 and more omega-3 fats both helped reduce liver fat and inflammation, and lowered the same harmful fat byproducts — showing the enzyme is a major way these fats hurt the liver.
