Asthenospermia; Genetic polymorphisms; NSUN7 gene

\Previous studies have shown that genetic polymorphisms in exon7 of the NSUN7 gene can be used as an infertility marker in Iranian men with asthenospermia. However, there have been no equivalent studies in China. In the present study, we investigated the possible association between the genetic polymorphisms in exon7 of NSUN7 and asthenospermia in a Chinese Han population. We ... more

Alcohol; Colorectal neoplasms; Cytochrome P-450 CYP1A1; Cytochrome P-450 CYP2E1; Genetic polymorphisms; Smoking

Polymorphisms in genes encoding P450 cytochrome enzymes may increase the risk of sporadic colorectal cancer (SCRC). Here we investigated the association between SCRC and CYP2E1 (PstI) and CYP1A1 (MspI) polymorphisms in a case-control study. Moreover, we sought to determine any possible associations between this disease and the sociodemographic factors. ... more

Genetic polymorphisms; Glutathione S-transferase; SA; Turabah

Glutathione-S-transferases (GST) are key phase II detoxifying enzymes that play critical roles in protection against products of oxidative stress and against electrophiles. Glutathione S-transferase mu (GST-M1) and theta (GST-T1) are isoforms of glutathione transferase enzymes that participate in the metabolism of a wide range of chemicals. Deletion variants ... more

Chemokine receptor type 2-V64I; Chemokine receptor type 5-Δ32; Genetic polymorphisms; Mixed population; Northeastern Brazil

Chemokines are low-molecular weight proteins that play a key role in inflammatory processes. Genomic variations in chemokine receptors are associated with the susceptibility to various diseases. Polymorphisms in chemokine receptor type 5 (CCR5)-Δ32 and CCR2-V64I are related to human immunodeficiency virus infection resistance, which has led to genetic association studies ... more

Breast cancer; Chemotherapy sensitivity; Genetic polymorphisms; Methylenetetrahydrofolate reductase

Activity of methylenetetrahydrofolate reductase (MTHFR), an enzyme involved in folate metabolism, is influenced by mutations in the corresponding gene, contributing to a decrease in 5,10-MTHF. Due to such polymorphisms, individuals differ in MTHFR enzyme activity and plasma folate levels. We investigated the relationship between two common MTHFR polymorphisms (C677T and A1298C) ... more

Biochemical markers; Genetic polymorphisms; Oxidative stress; Schizophrenia

We evaluated the association of glutathione S-transferase polymorphisms (GSTT1 and GSTM1) and oxidative stress biomarkers in patients with schizophrenia. A total of 162 subjects were studied: 53 had schizophrenia (Total Study Group-TSG), and 109 without the disorder (Total Control Group-TCG). To analyze oxidative stress, TSG was distributed into ... more

Brazilian population; Chronic lymphocytic leukemia; Genetic polymorphisms; Glutathione S-transferase

Genetic polymorphisms involved in carcinogen metabolism contribute to leukemogenesis risk. Epidemiological studies have revealed genetic alterations in chronic lymphocytic leukemia (CLL), including chromosome alterations, noncoding RNA alterations, and genetic polymorphisms. The bioactivation and detoxification of chemical agents is mediated by xenobiotic ... more

Androgen receptor; Breast cancer; Short tandem repeat

The androgen receptor (AR) is involved in the differentiation and growth of breast cancer. Genetic markers in the AR gene have a plausible role in modulating the risk of breast cancer. In this study, we studied the association of breast cancer and the trinucleotide repeat polymorphism (CAG)n in exon 1 of the AR gene in 202 patients with breast cancer and 183 healthy ... more

Cloning; Penta D allele; Sequencing; Short tandem repeat; Zhuang nationality

Kinship testing of a father and his son from Guangxi, China, the location of the Zhuang minority people, was performed using the PowerPlex® 18D System with a short tandem repeat typing kit. The results indicated that both the father and his son had an off-ladder allele at the Penta D locus, with a genetic size larger than that of the maximal standard allelic ladder. To further identify ... more
