Undifferentiated N2a cells were transfected with the indicated constructs and then subjected to 470-nm illumination (0.5 Hz) or kept in the dark, as indicated. After 48 h, the mRNA levels of the indicated genes were quantified via qRT-PCR. GAPDH and HPRT1 were used as control housekeeping genes (one-way ANOVA followed by the Tukey’s multiple comparison test; n = 3 independent experiments).
