Glutathione S-transferase distribution and concentration in human organs

Biochem Int. 1988 Mar;16(3):443-8.

Abstract

The concentration of basic, near-neutral and acid GSH S-transferase was measured in 18 organs from each of 9 male human subjects using radial immunodiffusion. Basic transferases were detectable in all tissues studied. Highest concentrations were found in liver, testis, kidney, adrenal and jejunum while low levels were found in bladder, muscle and thyroid. The concentration in liver was 230 times higher than that in thyroid. Near-neutral GSH S-transferase were absent in all tissues in 5 of the 9 individuals studied. When present they were widely distributed, highest concentrations being found in liver, testis, muscle, adrenal and brain and lowest levels in thyroid, lung, duodenum, stomach, heart and kidney. Acid GSH S-transferases were present in every individual studied although they were undetectable in the liver of a single subject. Highest concentrations were present in colon, jejunum, ileum, bladder, spleen and lung while low concentrations were found in liver. Our study provides conclusive evidence of marked inter-individual and inter-organ variation of the three groups of human GSH S-transferase.
