When obese women lose weight on a low-calorie diet, the activity of the lipoprotein lipase gene in fat tissue goes down, which affects how fats are stored in cells.

Scientific Claim

Energy restriction during a 10-week hypocaloric diet decreases lipoprotein lipase mRNA expression in subcutaneous adipose tissue of obese women.

Original Statement

“Levels of peroxisome proliferator-activated receptor γ co-activator 1α mRNA were increased, while the expression of the genes encoding leptin, osteonectin, phosphodiesterase 3B, hormone-sensitive lipase, receptor A for natriuretic peptide, fatty acid translocase, lipoprotein lipase, uncoupling protein 2 and peroxisome proliferator-activated receptor γ was decreased.”

Evidence Quality Assessment

Claim Status

appropriately stated

Study Design Support

Design supports claim

Appropriate Language Strength

definitive

Can make definitive causal claims

Assessment Explanation

The RCT design establishes causation for gene expression changes under hypocaloric conditions. The verb 'decreases' is appropriate for this causal claim.
