When scientists blocked one specific receptor (GPR40) in pig milk cells, the cells made about 38% less milk fat from oleic acid — blocking the other receptor (GPR120) had a smaller effect.
Scientific Claim
In porcine mammary epithelial cells, pharmacological inhibition of GPR40 reduces oleic acid-induced triglyceride accumulation by approximately 37.6%, while inhibition of GPR120 produces a more modest decrease.
Original Statement
“Pharmacological blockade revealed that GPR40 inhibition reduced triglyceride accumulation by approximately 37.6%, whereas GPR120 blockade produced a more modest decrease.”
Evidence Quality Assessment

overstated
Study Design Support
Design cannot support claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The claim cites a precise percentage, implying causal measurement, but without details on experimental replicates, controls, or statistical tests in the abstract, the strength of this quantitative claim cannot be verified.
More Accurate Statement
“In porcine mammary epithelial cells, pharmacological inhibition of GPR40 is associated with approximately 37.6% reduction in oleic acid-induced triglyceride accumulation, while inhibition of GPR120 is associated with a more modest decrease.”

Oleic acid-enriched diet improves maternal lactation performance and neonatal growth through GPR40 and GPR120 signaling pathways
The study found that blocking GPR40 cut fat buildup in milk-making cells by about 38%, while blocking GPR120 had a much smaller effect—exactly what the claim says.
