Abstract

The authors evaluated the diagnostic value of the glutathione-S-transferase (GST) enzyme in the medical practice. The GST is widely distributed in human tissues, the majority of the enzyme protein is present in the cytoplasm. GST plays a pivotal protective role against the environmental damages. It can be made a conclusion from the quantity, the localization of the enzyme expression and enzyme forms to the degree of chemical insult suffered by the organism. The increase of alpha GST izoenzyme can reflect the degree of the hepatocellular and renal proximal tubular epithelium damage. The overexpression of pi-class GST represents the injury of bile epithelium and renal distal tubules. Overexpression of GST is associated with tumor appearances and with resistance to cytostatic agents. It was possible to took the enzyme izoenzymes apart, to identify them--hereby to explore their origin--and to detect their quantity with the development of the separation techniques, the immunological and genetical methods. Since the enzyme expression is in direct proportion to the magnitude organs and tissues damage or/and the presence of specific izoenzymes suspects tumor formation, for this reason the monitoring of the GST expression could give a help for the physicians in creating the diagnosis.
