Figure 5. Per1 and Per2 transcript levels
Per1 (A) and Per2 (B) mRNA levels were measured in saline injected eyes (white circles) and in KA injected eyes (black circles) in DD. Per1 and Per2 mRNA levels were rhythmic in the retina of eyes injected with saline and KA (A,B; Kruskall-Wallis, p<0.01). mRNA levels were measured using real-time quantitative RT-PCR. Mean values are plotted with 8 animals per time; error bars represent the SEM. All values were normalized with respect to the values obtained at Zeitbeger time (ZT); dark-dark cycle (DD) ZT12 in saline injected eyes.
