Association between Paraoxonase/Arylesterase Activity of Serum PON-1 Enzyme and Rheumatoid Arthritis: A Systematic Review and Meta-Analysis

Antioxidants, 2022
Background: A decrease in serum paraoxonase (PON-1) and arylesterase (ARE) activity has been reported in rheumatoid arthritis (RA) patients and linked to chronic inflammation and impaired antioxidant defense.

Usefulness of the Measurement of Serum Paraoxonase-1 Arylesterase Activity in the Diagnoses of COVID-19

Biomolecules, 2022
The development of inexpensive, fast, and reliable screening tests for COVID-19 is, as yet, an unmet need. The present study was aimed at evaluating the usefulness of serum arylesterase activity of paraoxonase-1 (PON1) measurement as a screening test in ...

Functional, Structural and Genetic Modulation in Plasma and Renal Antioxidant Systems by Quercetin, Catechin and Genistein in Cisplatin-Induced Acute Nephrotoxicity in Wistar Rats. [PDF]

Food Sci Nutr
Cisplatin administration increases production of reactive oxygen species (ROS) as indicated by increased plasma renal biomarkers (KIM‐1, Cys‐C, BUN, CR), cellular damage indicators (MDA, AOPP, 8‐OHdG) and histopathology of kidney. Co‐exposure along with quercetin, catechin and genistein restored the renal functions which may be due to direct ROS ...

Endothelial Lipase Modulates Paraoxonase 1 Content and Arylesterase Activity of HDL

International Journal of Molecular Sciences, 2021
Endothelial lipase (EL) is a strong modulator of the high-density lipoprotein (HDL) structure, composition, and function. Here, we examined the impact of EL on HDL paraoxonase 1 (PON1) content and arylesterase (AE) activity in vitro and in vivo.

Arylesterase activity of paraoxonase 1 (PON1) on HDL3 and HDL2: Relationship with Q192R, C-108T, and L55M polymorphisms

Biochemistry and Biophysics Reports, 2021
Background Controversy exists regarding the role of the subfractions of high-density lipoproteins (HDL2 and HDL3) in cardiovascular disease. The functionality of these particles, and their protective role, is due in part to the paraoxonase 1 (PON1 ...

Paraoxonase 1 and Chronic Obstructive Pulmonary Disease: A Meta-Analysis

Antioxidants, 2021
Oxidative stress is a driving factor in the pathophysiology of chronic obstructive pulmonary disease (COPD). While paraoxonase 1 (PON1) is an antioxidant enzyme and a potential biomarker of this disease, data regarding the status of PON-1 in COPD are ...

Separation and quantitative recovery of mouse serum arylesterase and carboxylesterase activity

Journal of Lipid Research, 2004
Paraoxonase-1 (PON1) is known to be associated with high density lipoproteins. We optimized buffer conditions to obtain quantitative recovery of PON1 (arylesterase) activity and analyzed the distribution of PON1 in mice using a combination of size ...
