Figure 4.White LED light influences the circadian rhythm of clock-related genes in HT-22 cells. (A–B) Clock and bmal1 mRNA, showing time-phase shift and suppressed oscillation amplitudes in Light group; (C) Rorα mRNA, showing diminished circadian rhythm and a continous increase in mRNA abundance over the period of examination in Light group; (D–E) Per1, per2 and per3 mRNA expression, showing reduced oscillation frequencies in Light group; (G–H) Cry1 and cry2 mRNA, displaying obvious time-phase shift and significantly suppressed oscillation amplitudes in Light group; (I) Rev-erbα mRNA, showing an obvious time-phase shift in Light group.
