The cardio protective functions of HDL are attributed to the HDL-associated proteins like Paraoxonase 1 (PON1). PON1 is associated with HDL through a N-terminal signal peptide. HDL-associated PON1 alone is cardio protective.

Paraoxonase (PON1) as a biomarker of susceptibility for organophosphate toxicity
Paraoxonase (PON1) is an A-esterase capable of hydrolysing the active metabolites (oxons) of a number of organophosphorus (OP) insecticides such as parathion, diazinon and chlorpyrifos.

PON1 status does not influence cholinesterase activity in Egyptian agricultural workers exposed to chlorpyrifos [PDF]
Animal studies have shown that paraoxonase 1 (PON1) genotype can influence susceptibility to the organophosphorus pesticide chlorpyrifos (CPF). However, Monte Carlo analysis suggests that PON1 genotype may not affect CPF-related toxicity at low exposure ...

The growing importance of PON1 in cardiovascular health: a review
The wide acceptance of the oxidation theory of atherogenesis has prompted attention to antioxidant mechanisms, particularly the prevention of lipid oxidation by high-density lipoprotein-associated proteins like paraoxonase 1 (PON1) enzyme.

The levels and activity of the enzyme paraoxonase 1 affect the vulnerability to the teratogenic effects of organophosphate pesticides. Mutant mice lacking the gene for paraoxonase1 (PON1-/-) are more susceptible to the toxic effects of chlorpyrifos, and ...

Main Determinants of PON1 Activity in Hemodialysis Patients
Cardiovascular diseases are the major cause of morbidity and mortality in hemodialysis (HD) patients. These patients present reduced paraoxonase 1 (PON1) activity that depends on genetic and non-genetic factors; however, how these factors influence PON1 ...
