Enzyme Regulation: It can upregulate the expression of manganese superoxide dismutase ( $\text{Mn}-\text{SOD}$ ) in the mitochondrial matrix by activating and expressing $\text{Be}-2$ associated $\text{X}$ protein.
Gene Activation: It can also activate nuclear factor erythroid 2-related factor 2 ( $\text{Nrf}2$ ) to exert its antioxidant effects.
