Fig 4. PON1 arylesterase activity in the healthy subjects and the ACS patients and based on their PON1 192 genotype.

The PON1 Q192R genotype was determined by RT-PCR. PON1 arylesterase activity was measured by the increase in absorbance at 270 using phenylacetate as a substrate. Results are expressed as means ± SEM. ** p<0.001 and ****p<0.0001 for the ACS patients compared to the healthy subjects with the same PON1 Q192R polymorphism.
