Background: Indians are known to have the highest rates of coronary artery disease (CAD), with the conventional risk factors failing to explain the increased risk. Possible candidate genes to study both the environmental and genetic risk associated with CAD is the glutathione S-transferase (GST) family, as it is involved in detoxification.

Methods: This case-control assessed the association between GSTM1 and GSTT1 polymorphisms in Indian patients with CAD. Fifty patients with CAD and 50 healthy volunteers were genotyped for the two polymorphisms by polymerase chain reaction. The genotype frequencies between the groups were compared, where a p-value of less than 0.05 was considered as statistically significant.

Results: There was a significant inverse association between GSTT1 null polymorphism and CAD susceptibility.

Machine learning approaches and genetic determinants that influence the development of type 2 diabetes mellitus: a genetic association study in Brazilian patients.

Braz J Med Biol Res

Laboratório de Patologia Molecular, Instituto de Ciências Biológicas, Universidade Federal de Goiás, Goiânia, GO, Brasil.

This genetic association study including 120 patients with type 2 diabetes mellitus (T2DM) and 166 non-diabetic individuals aimed to investigate the association of polymorphisms in the genes GSTM1 and GSTT1 (gene deletion), GSTP1 (rs1695), ACE (rs4646994), ACE2 (rs2285666), VEGF-A (rs28357093), and MTHFR (rs1801133) with the development of T2DM in the population of Goiás, Brazil. Additionally, the combined effects of these polymorphisms and the possible differences between sexes in susceptibility to the disease were evaluated. Finally, machine learning models were integrated to select the main risk characteristics for the T2DM diagnosis.

Glutathione S-transferases (GSTs) play a significant role in carcinogen detoxification, and hence, polymorphisms of this gene may lead to lung cancer susceptibility. Accordingly, this study is aimed at investigating GSTM1 and GSTT1 polymorphisms' association with lung cancer risk and their effects on the toxicities of platinum-based chemotherapy used to treat Bangladeshi lung cancer patients. The study subjects comprised 180 lung cancer patients and 200 healthy volunteers.

GSTM1 and GSTT1 deletions in penile cancer are associated with TNM stage but not with HPV DNA status.

Deletions of the GSTT1 and GSTM1 are associated with chemical carcinogenesis and genitourinary malignancies like bladder cancer, where they correlate with increased tumor aggressiveness. In uterine cervical lesions, GSTT1 and GSTM1 deletions have also been suggested to facilitate the persistence of human papillomavirus (HPV) infection and HPV-induced carcinogenesis. This work addresses the hypothesis that GSTT1/GSTM1 deletions are associated with presence of HPV DNA and aggressiveness in penile cancer, a rare malignancy with HPV+ and HPV- subtypes.

Introduction: In noise-induced hearing loss (NIHL), glutathione S-transferases (GSTs) play a pivotal role as antioxidants in cochlear protection. Nevertheless, the variability in population and environmental factors complicates the interpretation of research findings on the association among GST gene polymorphism, GST enzyme activity, and NIHL, leading to inconsistent results. To explore the potential correlation between them, we took a cross-sectional survey.

Article Synopsis
  • Mutations in genes responsible for detoxifying oxidative stress are thought to increase the risk of lung cancer, but the link between waterpipe tobacco smoking and genetic factors is not well understood.
  • This study explores the relationship between waterpipe smoking and specific gene variants (GSTP1, GSTM1, and GSTT1) in Iraqi male smokers, using genetic testing on 123 lung cancer cases and 129 controls.
  • While no direct association was found between the gene variants and lung cancer risk, combining waterpipe smoking with certain gene null variants significantly increased cancer risk, suggesting a complex interaction rather than a straightforward genetic link.
