GSTM1; GSTT1; Meta-analysis; Polymorphism; Varicocele

The glutathione S-transferase (GST) family represents a major group of detoxification and antioxidant enzymes. Studies have shown that high oxidative stress levels are associated with varicocele. The objective of this study was to assess the relationship between GSTM1 and GSTT1 null polymorphisms and varicocele using a study group of 497 varicocele patients and 476 ... more

Cervical cancer; GSTM1; GSTT1; Smoking

Human papillomavirus infection is the main risk factor for cervical cancer. Other risk factors include smoking and genetic susceptibility. Glutathione-S-transferases are enzymes involved in tobacco carcinogen metabolism, and genes encoding these enzymes are highly polymorphic. We compared the frequencies of GSTM1 and GSTT1 null polymorphisms in ... more

Atherosclerosis; eNOS; GSTM1; GSTT1; Hypertension

Atherosclerosis is a multifactorial chronic inflammatory disease that occurs in response to endothelial aggression. Systemic arterial hypertension is the main risk factor for the formation of atheromas, increasing the risk of cardiovascular diseases. Several genes are involved in atherogenesis and hypertension. We analyzed polymorphisms of candidate genes that ... more

GSTM1; GSTT1; Polymorphism; Prognosis; Sickle cell anemia

Sickle cell anemia is one of the most common genetic diseases in Brazil. This disease has an autosomal recessive inheritance pattern with a point mutation on chromosome 11, which is the substitution of an adenine by thymine. This mutation leads to the exchange of a glutamic acid for a valine at residue 6 of the beta globin chain, resulting in an abnormal form of hemoglobin, the so-called ... more

GSTM1; GSTT1; Polymorphism; Prostate cancer; Risk factor

Prostate cancer (PCa) is the second most common type of tumor among men over 50 years old and its etiology includes environmental, demographic, and genetic risk factors. We investigated a possible association between GSTM1 and GSTT1 polymorphisms, sociodemographic, and clinical factors with PCa in a population of southwestern Bahia, Brazil. The ... more

ARG1 gene; Arsenic resistance; Glutathione; Glutathione-S-transferase; MRP2; Transfection

To study the relationship between arsenic resistance of 293T cells and overexpression of ARG1, the ARG1 gene in a recombinant plasmid was transfected into 293T cells via liposomes, and then ARG1 overexpression was examined by real-time PCR and immunocytochemistry. The survival rate, arsenic accumulation and arsenic efflux, GSH level, and GST activity of 293T cells overexpressing ARG1 ... more

Chemotherapy; GSTM1; GSTP1 polymorphism; GSTT1; NSCLC

The aim of this study was to evaluate the association of GSTM1 null/present, GSTT1 null/present, and GSTP1 IIe105Val polymorphisms with the chemotherapy response and overall survival of advanced NSCLC. Two hundred and sixty-two patients with histologically confirmed advanced NSCLC (inoperable TNM stages IIIA, IIIB, and IV) were enrolled to this hospital-based ... more

Albuminuria; Essential hypertension; Lectin-like oxidized low-density lipoprotein receptor 1; Polymorphisms

Albuminuria is an independent predictor of renal and cardiovascular complications in hypertensive subjects. We previously showed that lectin-like oxidized low-density lipoprotein receptor 1 (OLR-1) polymorphisms at G501C are associated with susceptibility to essential hypertension and serum C-reactive protein levels. We have now investigated a possible association between OLR-1 polymorphisms ... more

Osteosarcoma; Polymorphisms; VEGF

The aim of this study was to assess the role of the VEGF -2578C/A, +936C/T, and -460T/C gene polymorphisms in the development of osteosarcoma. A total of 182 patients with osteosarcoma and 182 age- and gender-matched healthy controls were enrolled into our study during January 2011 and December 2013. Genotype frequencies of the VEGF -2578C/A and -460T/C alleles in controls ... more

Bone mineral density; Human leukocyte antigen-A; Polymerase chain reaction-sequence-based typing; Polymorphisms; Postmenopausal osteoporosis

Osteoporosis is a common disease characterized by low bone mineral density, deterioration in bone microarchitecture, and increased fracture risk and is more prevalent in postmenopausal women. HLA is a complex gene family; previous studies have shown that it plays an important role in the pathogenesis of osteoporosis among Japanese and Greek populations. Prompted by these findings ... more
