From: Brazilian green propolis water extract up-regulates the early expression level of HO-1 and accelerates Nrf2 after UVA irradiation

By western blot analysis, Nrf2 is almost not detected in nuclear fraction at 3, 6 h after UVA irradiation. Nrf2 expression level in cytosolic and nuclear fraction of NB1-RGB cells was evaluated using western blotting 3, 6 h after UVA irradiation. (a) 3 h after UVA irradiation, and (b) 6 h after UVA irradiation. At all time points, WEP was applied at a concentration of 30 μg/mL
