FIVE GLUTATHIONE S-TRANSFERASE GENE VARIANTS IN 23,452 CASES OF LUNG CANCER AND 30,397 CONTROLS: META-ANALYSIS OF 130 STUDIES.

Five glutathione s-transferase gene variants in 23,452 cases of lung cancer and 30,397 controls: meta-analysis of 130 studies.

Glutathione S-transferases (GSTs) are known to abolish or reduce the activities of intracellular enzymes that help detoxify g fuel spiderverse environmental carcinogens, such as those found in tobacco smoke.It has been suggested that polymorphisms in the GST genes are risk factors for lung cancer, but a large number of studies have reported apparen
