Hypothesis
Does FAAH and MGL activity in human subcutaneous adipocytes correlate with body mass index (BMI) and other markers of adiposity and metabolism?
Conclusion
FAAH activity in subcutaneous adipocytes increases with BMI, while MGL activity does not correlate with BMI or other metabolic markers.
Supporting Evidence
- FAAH activity positively correlates with BMI and waist circumference.
- MGL activity shows no relationship with BMI or other adiposity indices.
- FAAH activity does not correlate with fasting serum insulin, glucose, or adipokine levels.
Takeaway
This study found that as people get heavier, a specific enzyme in their fat cells becomes more active, but another enzyme does not change.
Methodology
Subcutaneous adipocytes were isolated from fasting blood samples of 28 metabolically healthy subjects, and FAAH and MGL activities were measured using radiolabelled substrates.
Potential Biases
Potential bias due to the exclusion of subjects with metabolic diseases and the small sample size.
Limitations
The study only included metabolically healthy subjects and did not assess the effects of obesity-related metabolic diseases.
Participant Demographics
14 males and 14 females aged 20-48 years with a BMI range of 19.1-33.8 kg/m².
