Human glutathione S-transferases: radioimmunoassay studies on the expression of alpha-, mu- and pi-class isoenzymes in developing lung and kidney.
The developmental expression of the alpha-, mu- and pi-class glutathione S-transferases has been defined in human lung and kidney using radioimmunoassay, immunohistochemistry and column chromatography. Expression of alpha-class enzymes increased significantly after about 40 weeks gestation in kidney but not lung, while expression of mu isoenzymes was continuous throughout development in both tissues. Expression of the pi isoenzyme fell during in utero ontogeny in lung, the pattern of down-regulation being similar to that previously observed in liver. There was no change in the expression of this isoenzyme in kidney. Comparison of the expression of the glutathione S-transferases in developing lung, kidney and liver shows some common patterns of expression suggesting these genes are under similar regulatory control.
