Moreover, the same NO/cGMP signaling was effective in survival cell response to GSH depletion in skeletal muscle cells ( On the basis of these knowledge, it is not surprising that alterations in GSH homeostasis have been implicated in the etiology and/or progression of many human diseases ( In this review we briefly summarize the mechanisms of GSH synthesis and homeostasis, while we will focus on the strict connection between GSH levels and oxidative/nitrosative stress and on the downstream redox changes that modulate signaling pathways involved in viral infection and autophagy (ATG)

1- Free GSH=DTNB+Sample+Substrate 2- Total GSH=DTNB+Sample+Substrate+ NADPH+glutathione reductase 3- GSSG=Total GSH-Free GSH Another method to measure GSSG separately, is to remove the free GSH from DTNB reaction process by modification of free GSH with N-ethylmaleimide (NEM) or vinylpyridine prior to conducting assay
