..., a functional impairment of high-density lipoprotein (HDL) has been observed. Although the actual players are unknown, anti-HDLs were associated with altered lipid profile, decreased paraoxonase 1 (PON1) activity and CV disease in RA. Therefore, we aimed to evaluate whether the presence of antibodies against...

... 8 weeks, and after 4 weeks washout. Polymorphisms in the gene for the antioxidant enzyme paraoxonase-1 gene (position 192) were measured. The diabetics had increased DNA oxidative susceptibility ( P = 0.008), without increased LDL oxidative susceptibility. There was a direct relationship between DNA...

... of atherosclerosis in humans by increasing reverse cholesterol transport and inhibiting the oxidation of low-density lipoprotein (LDL) due to the paraoxonase content of HDL. The purpose of the present study was to assess if there are any relationships between in vivo increases in serum levels of immunological LDL...

...Bharti MACKNESS; Paul N. DURRINGTON; Bashir ABUASHIA; Andrew J. M. BOULTON; Michael I. MACKNESS Human serum paraoxonase 1 (PON1) is located on high-density lipoprotein and has been implicated in the detoxification of organophosphates, and possibly in the prevention of lipid peroxidation of low...
