A study showed that 3,5,6,7,8,3′,4′-heptamethoxyflavone had the ability to induce brain-derived neurotrophic factor production in astrocytes and enhance neurogenesis after brain ischemia, which may be mediated by activation of extracellular signal-regulated kinases 1/2 (ERK1/2) and cAMP response element-binding protein [106]. Here, MAPK3 is linked to brain ischemia.
