112 When GSH is oxidized, it forms GSH disulphide, which can be reduced again to GSH with the help of glutathione reductases, another Nrf2 targets, in an NADPH-dependent manner
Elevated Sod2 activity augments matrix metalloproteinase expression: evidence for the involvement of endogenous hydrogen peroxide in regulating metastasis
Thus, damage to mitochondrial DNA and loss of can further increase ROS production, thereby creating a cycle of dysfunction that includes increased ROS production by the respiratory chain, activation of signal transduction pathways, and potentially, leading to apoptosis or necrosis, as well as the release of cytochrome c, which triggers apoptosis
In this study, phosphotoxic protein inhibited melanin synthesis by downregulating the expression of MITF, TRP-1, TRP-2, and tyrosinase in B16F10 cells and reducing cAMP levels (Jung et al., 2012)
