Paraoxonase 1 (PON1) is a high-density lipoprotein (HDL)-associated enzyme involved in the protection of low-density lipoprotein and HDLs against lipid peroxidation. Several studies documented the capacity of polyphenols to stimulate PON1 transcription activation. The objective of the present review is to provide the main evidence about the role and the potential mechanism of action of polyphenols and polyphenol-rich foods in the modulation of PON1 gene expression and activity. A total of 76 in vitro and in vivo studies were included in the review...

Homocysteine and its modulating genes have strongly emerged as novel biomarkers for coronary artery disease (CAD). In present study, we investigated whether polymorphisms in homocysteine pathway genes and the plasma levels of homocysteine, folate and vitamin B12, independently or in combination, are associated with CAD risk. A total of 504 participants were recruited (cases n = 254, controls n = 250, respectively). Tetra primer allele refractory mutation system (ARMS) PCR was used for resolving the genotypes of 5'10' methylenetetrahydrofolate reductase 'MTHFR' polymorphisms (rs1801133, rs1801131), 5' methyl tetrahydrofolate homocysteine methyltransferase 'MTR' polymorphism (rs1805087), paroxanse1 'PON1' polymorphism (rs662), and cystathionine beta synthase 'CBS' polymorphism (rs5742905)...

BACKGROUNG: Numerous reports have shown that psoriasis patients are more exposed to lipoprotein peroxidation and to a decrease in the activity of paraoxonase (PON)1, an anti-oxidant and anti-inflammatory enzyme. Thus, it has been suggested that malfunction of the anti-oxidant system and an increased production of reactive oxygen species drive immune inflammatory events, that result in progressive skin cell damage in patients with psoriasis. The PON protein family, including PON1, PON2 and PON3, is one of the most important endogenous defense mechanisms against oxidative stress...

Paraoxonase-1 (PON1) gene polymorphisms have been closely associated with the development of advanced cancers while PON1 secretion to the serum is linked with inhibition of oxidized high-density lipoprotein by its antioxidative function. Our group previously demonstrated that post-translational modification of serum PON1 in form of fucosylated PON1 is a potential biomarker of small cell lung cancer. Here, we interrogated the role of PON1 in the pathobiology of lung cancer (LC) by addressing cell-autonomous mechanisms using gain-of-function and loss-of-function approaches and protein expression profiling of tissue samples in our clinical biobank...

In this study, we explored associations between paraoxonase 1 (PON1) L55M and Q192R gene polymorphisms and the risk of breast cancer in 365 female breast cancer patients and 378 healthy controls from the Guangxi region of southern China. The LM heterozygous and MM homozygous genotypes, as well as M carrier status and M alleles, were associated with an increased risk of breast cancer. In addition, the M allele was associated with postmenopausal status and increased nodal involvement. In contrast, none of the Q192R genotypes or alleles were associated with a change in breast cancer risk, or with any of the clinicopathological parameters...

BACKGROUND: Although there have been significant advances for clarifying the pathogenesis of psoriasis, exact pathogenic mechanism of the disease is still unknown. Oxidative stress is considered to be a new aetiopathogenetic key factor in the pathogenesis of psoriasis, as a result of the studies performing the association between psoriasis and paraoxonase 1 (PON1) activity. In this study, we aimed to examine the possible associations between the both PON1 L55M and PON1 Q192R polymorphisms and psoriasis susceptibility and disease progression in Turkish population...

BACKGROUND: Prenatal environmental conditions may influence disease risk in later life. We previously found a gene-environment interaction between the paraoxonase 1 (PON1) Q192R genotype and prenatal pesticide exposure leading to an adverse cardio-metabolic risk profile at school age. However, the molecular mechanisms involved have not yet been resolved. It was hypothesized that epigenetics might be involved. The aim of the present study was therefore to investigate whether DNA methylation patterns in blood cells were related to prenatal pesticide exposure level, PON1 Q192R genotype, and associated metabolic effects observed in the children...

A key factor protecting from oxidative stress in gestational diabetes mellitus (GDM) and in type 2 diabetes (T2D) is paraoxonase-1 (PON1). Inconclusive and limited data exist regarding the effect of a coding polymorphism (Q192R) of the PON1 gene in conferring susceptibility to both states. In the present study, we investigated the association between the PON1 gene and the risk for GDM in the Greek population and assessed for the first time its transcriptional efficiency. We studied 185 women with GDM and 104 non-diabetic controls for the PON1 polymorphism...

Prenatal exposure to mercury, a known neurotoxic metal, is associated with lower cognitive performance during childhood. Disruption of fetal epigenetic programming could explain mercury's neurodevelopmental effects. We screened for epigenome-wide methylation differences associated with maternal prenatal blood mercury levels in 321 cord blood DNA samples and examined the persistence of these alterations during early (n = 75; 2.9-4.9 years) and mid-childhood (n = 291; 6.7-10.5 years). Among males, prenatal mercury levels were associated with lower regional cord blood DNA methylation at the Paraoxonase 1 gene (PON1) that persisted in early childhood and was attenuated in mid-childhood blood...

PURPOSE: Studies have found that pomegranate juice (PJ) consumption increases the binding of high-density lipoproteins (HDL) to paraoxonase 1 (PON1), thus increasing the catalytic activity of this enzyme. PON1 is an antioxidant arylesterase synthesized in the liver and transported in plasma in association with HDL. Decreased levels of PON1 are associated with higher levels of cholesterol. We determined the effects of PJ on body weight, cholesterol, and triacylglycerols through 5 months of supplementation...

Paraoxonase 1 (PON1) is a calcium-dependent lactonase synthesized primarily in the liver and secreted into the plasma, where it is associates with high density lipoproteins (HDL). PON1 acts as antioxidant preventing low-density lipoprotein (LDL) oxidation, a process considered critical in the initiation and progression of atherosclerosis. Additionally, PON1 hydrolyzes and detoxifies some toxic metabolites of organophosphorus compounds (OPs). Thus, PON1 activity and expression levels are important for determining susceptibility to OPs intoxication and risk of developing diseases related to inflammation and oxidative stress...
