MBE and delphinidins suppressed the increase of ATF4 expression in 661W cells exposed to blue light. (A, C, E) Representative images of immunoblots of whole cell lysates obtained from 661W cells incubated with MBE (A, C, E), D3S5G (C), and D3G5G (E) for the indicated times exposed to blue light. (B, D, F) The graph represents the relative protein level of ATF4 normalized to that of β-actin (Vehicle = 1). Bar graphs show the mean ± SEM.
