Gamma-glutamyl transpeptidase, triglycerides, and enzyme induction
British Medical Journal
|January 4, 1975
Summary
Serum gamma-glutamyl transpeptidase (gamma-GT) activity is linked to higher triglyceride and pre-beta-lipoprotein levels in patients. This suggests liver enzyme induction may play a role in hyperlipidemia.
Area of Science:
- Biochemistry
- Clinical Chemistry
- Metabolic Research
Background:
- Elevated serum triglycerides are a risk factor for cardiovascular disease.
- Gamma-glutamyl transpeptidase (gamma-GT) is an enzyme found primarily in the liver.
- Lipoprotein profiles, including triglyceride and pre-beta-lipoprotein levels, are crucial for assessing cardiovascular risk.
Purpose of the Study:
- To investigate the association between serum gamma-glutamyl transpeptidase (gamma-GT) activity and lipid/lipoprotein concentrations.
- To explore potential mechanisms linking gamma-GT to hyperlipidemia.
Main Methods:
- A study involving 109 consecutive patients undergoing routine lipid screening.
- Measurement of serum gamma-GT activity, triglyceride concentration, and pre-beta-lipoprotein concentration.
Main Results:
- A significant positive association was found between serum gamma-GT activity and serum triglyceride concentration.
- A significant positive association was also observed between serum gamma-GT activity and serum pre-beta-lipoprotein concentration.
Conclusions:
- Serum gamma-GT activity is positively associated with triglyceride and pre-beta-lipoprotein levels.
- These findings suggest that hepatic microsomal enzyme induction in hyperlipidemic individuals may increase triglyceride synthesis.
