[Change in glutathione content in rat thymocytes under apoptosis induced by H2O2 or irradiation]
Abstract:
Glutathione (GSH) content as well as GSH-peroxidase and GSH-reductase activity in isolated rat thymocytes X-irradiated in a dose of 4.5 Gy or treated with 0.1 mM H2O2 were studied in a period preceding the appearance of apoptosis morphological symptoms. The early adaptive response of thymocytes to radiation - increase of both GSH content and glutathione peroxidase and glutathione reductase activity was revealed. On the contrary the rapid fall of GSH level in H2O2-treated thymocytes was observed simultaneousely with glutathione reductase inhibition and enhanced GSH consumption by glutathione peroxidase, this disbalance of GSH-dependent antioxidant system probably facilitates mitochondrial way of apoptosis.
