Glutathione, cell proliferation and differentiation

HRA Ashtiani, AK Bakhshandi, M Rahbar, A Mirzaei, A Malekpour, H Rastegar


All organisms require an equivalent source for living. Reduced glutathione is the most abundant thiol containing protein in mammalian cells and organs. Glutathione was discovered by Hopkins in 1924 who published his findings in JBC. It is a three peptide containing glutamic acid, cystein and glycin and is found in reduced and oxide forms in cell. High concentration of glutathione and its high reduced/oxide potential makes GSH a powerful antioxidant and the first defense line against free radicals. However, glutathione is the most efficient tool for detoxification of xenobiotic. In several studies, the effect of GSH on different cell types has been investigated and so, in this study, a review of the glutathione function, focusing on cell proliferation and differentiation would be carried out.

Key words: Glutathione, proliferation, differentiation
