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 ...

Noncatalytic Functions Are Required for MPO and PON1 in Modulating the Involvement of Monocytes and Endothelial Cells in Atherosclerosis. [PDF]

Biochem Res Int
High‐density lipoproteins (HDLs) are deeply implicated in atherosclerosis. HDL, myeloperoxidase (MPO), and paraoxonase‐1 (PON1) form a functional ternary complex where PON1 partially inhibits the MPO activity, and MPO in turn partially inactivates PON1.

Paraoxonase and arylesterase activity in bladder cancer [PDF]

Urology Research and Practice, 2019
Abstract Objective: Oxidative stress is the main pathogenetic mechanism in bladder cancer among many other causes. We aimed to investigate whether a potential relationship exists between bladder cancer and the activities of paraoxonase (PON1) and arylesterase (ARE) enzymes.

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 ...

Decreased serum PON1 arylesterase activity in familial hypercholesterolemia patients with a mutated LDLR gene

Genetics and Molecular Biology, 2018
Paraoxonase 1 (PON1) is a serum enzyme associated with high density lipoprotein (HDL) regulation through its paraoxonase and arylesterase activity. PON1 inhibits the oxidation of HDL and low density lipoprotein (LDL), and is involved in the pathogenesis ...
