In particular, Bai et al. evaluated EGCG effects on angiogenesis after stroke and the involvement of Nrf2, using a MAPK/extracellular signal-related kinase (MAPK/ERK) inhibitor, given that EGCG was reported to induce Nrf2-mediated antioxidant action through the MAPK/ERK pathway. Here, NFE2L2 is linked to stroke disorder.
