Abstract excerpt
Genes coding for the glutathione S-transferase M1 (GSTM1) and Theta 1 (GSTT1) proteins are polymorphic in humans and these genes are absent, or homozygous null, in 10-60% of different ethnic populations. These enzymes catalyze the conjugation of glutathione to numerous carcinogenic chemicals and previous epidemiologic studies have associated the null genotypes of these GST genes with higher risk of cancer. In...
