The Claim
No significant interaction exists between the USF1 usf1s1 C>T and usf1s2 G>A polymorphisms and the HSL -60C>G polymorphism in their effect on antilipolytic insulin sensitivity among 407 Caucasian adults, indicating that the influence of USF1 variants on insulin-mediated suppression of lipolysis is independent of HSL genetic variation.
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.
Genetic variations in the USF1 gene affect how insulin suppresses fat breakdown, but this effect does not change based on whether a person also has a specific variation in the HSL gene.
See the scientific wording
No significant interaction was observed between the USF1 usf1s1 C>T and usf1s2 G>A polymorphisms and the HSL -60C>G polymorphism on antilipolytic insulin sensitivity in 407 Caucasian adults, suggesting that the effect of USF1 variants on insulin-mediated lipolysis suppression is independent of HSL variation.
When certain versions of the USF1 gene are present, they make the body more sensitive to insulin’s signal to stop breaking down fat. This happens because the gene makes more of a protein that controls another protein (HSL) that breaks down fat. When insulin is present, this control works better, so less fat is released into the blood.
What the research says
1 studyScientists found that certain gene changes in USF1 make the body better at stopping fat breakdown when insulin is present, but this effect doesn’t depend on another gene called HSL — they work separately.
