The Claim
Grain feeding in yaks reduces PNPLA2 gene expression, leading to suppressed lipid mobilization and increased intramuscular fat accumulation.
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.
Feeding yaks grain lowers the activity of the PNPLA2 gene, which reduces the breakdown of fat in muscle tissue and results in higher fat content within the muscle.
See the scientific wording
Grain feeding in yaks reduces expression of PNPLA2, a gene involved in fat breakdown, which may contribute to increased intramuscular fat accumulation by suppressing lipid mobilization.
When yaks eat grain, their bodies get more energy than they need, which turns on genes that make and store fat while turning off genes that break down fat. This causes fat to build up inside muscle tissue instead of being used for energy, making the meat fattier and more tender.
What the research says
1 studyFeeding yaks grain makes their meat fattier, and the study shows this happens because genes that normally break down fat, like PNPLA2, become less active. So grain feeding slows down fat breakdown, letting more fat build up in the muscle.
