BACKGROUND Glutathion S-transferase P1 (GSTP1), the abundant isoform of glutathione S-transferase in lung epithelium, plays an important role in cellular protection against oxidative stress and toxic foreign chemicals. GSTP1 (Ile105Val) polymorphism has been reported to be associated with asthma related phenotypes such as atopy and bronchial hyperresponsiveness. Therefore we investigated whethe...

Thiazolides are a novel class of broad-spectrum anti-infective drugs with promising in vitro and in vivo activities against intracellular and extracellular protozoan parasites. The nitrothiazole-analogue nitazoxanide (NTZ; 2-acetolyloxy-N-(5-nitro 2-thiazolyl) benzamide) represents the thiazolide parent compound, and a number of bromo- and carboxy-derivatives with differing activities have been...

BACKGROUND/AIMS Increasing evidence shows that oxidative stress plays an important part in the pathophysiological mechanisms of preeclampsia (PE). Polymorphic variants of oxidative stress-related candidate genes GST1 and GPX1 can affect the antioxidant activities of their encoded enzymes. Therefore, this study aimed to explore the associational analysis between GSTP1 and GPX1 single nucleotide ...

BACKGROUND Glutathione S-transferase P1 (GSTP1) is thought to be involved in the detoxification of reactive carcinogen metabolites. Numerous epidemiological studies have evaluated the association of GSTP1 Ile105Val polymorphism with the risk of prostate cancer. However, the results remain inconclusive. To derive a more precise estimation, a meta-analysis was performed. METHODOLOGY/PRINCIPAL F...

BACKGROUND Early-life exposure to p,p'-DDT [2,2-bis(p-chlorophenyl)-1,1,1-trichloroethane] is associated with a decrease in cognitive skills among preschoolers at 4 years of age. We hypothesized that genetic variability in glutathione S-transferase (GST) genes (GSTP1, GSTM1, and GSTT1) could influence the effects of prenatal exposure to p,p'-DDT. METHODS We used data from 326 children assesse...

This study aimed to investigate the association of the GSTP1 gene polymorphism with the outcomes and toxicities of treatments in breast cancer. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated for the association of GSTP1 polymorphism with tumour response and toxicities, and the hazard ratios (HRs) and 95% CIs were calculated for the association between GSTP1 polymorphis...

BACKGROUND The aim of this study was to determine whether expressions of the excision repair cross-complementing (ERCC1), thymidylate synthase (TS), and glutathione S-transferase P1 (GSTP1) predict clinical outcome in patients with advanced gastric cancer treated with fluorouracil (5-fluorouracil)/oxaliplatin chemotherapy. PATIENTS AND METHODS The study population consisted of 64 advanced gas...

The glutathione S-transferase P1 genotype (GSTP1) is involved in the inactivation of cigarette smoke carcinogens, and sequence variation in the gene may alter bladder cancer susceptibility. To examine the association between GSTP1Ile 105Val and bladder cancer, the authors undertook a meta- and pooled analysis. Summary crude and adjusted odds ratios and corresponding 95% confidence intervals wer...

Glutathione Stransferases (GSTs) are a group of enzymes that act to detoxify reactive oxygen species resulting from oxidative stress processes and melanin production. GSTP1 is a polymorphic gene encoding variant proteins involved in metabolism. The role of the rs1695*A/G GSTP1 Ile105Val polymorphism in cutaneous malignant melanoma (CMM) susceptibility remains controversial. Two recent metaanaly...

The enhanced neurotoxicity of the Parkinson's disease-associated LRRK2 mutant, G2019S, than its wild-type counter-part has recently been reported. Overexpression of LRRK2 (G2019S) in cultured neural cells results in caspase-3-dependent apoptosis via a yet undefined signaling pathway. Elucidation of the mechanism underlying LRRK2 (G2019S) neurotoxicity may offer new insights into the pathogenesi...
