Abstract excerpt
The GSTP1 gene encodes for an enzyme, glutathione S-transferase pi (GSTpi),involved in detoxification of carcinogens. An aminoacid substitution (I105V) in GSTP1 produces a variant enzyme with lower activity and less capability of effective detoxification. This variant GSTP*B allele has been associated with a propensity to develop several neoplasms. Because GSTP1 promoter hypermethylation and inactivation of GSTpi...
