Chemical and molecular mechanisms of antioxidants: experimental approaches and model systems
For Glutathione for rheumatoid arthritis, this ratio is pivotalRA patients often show a 30-50% GSH deficit, correlating with disease flares [10]
This activates protein kinase A (PKA), which phosphorylates and stabilizes MITF (microphthalmia-associated transcription factor), driving transcriptional upregulation of tyrosinase, TRP-1, and TRP-2rate-limiting enzymes in the eumelanin biosynthesis pathway (Abdel-Malek et al., Pigment Cell Research, 2001)
Since GPxs-mediated intervention is expected to regulate mainly the peroxides-activated signaling pathways, its overall contribution for offering resistance against radiation-induced cell death may be limited [1, 8,9,10]
