Figure 2

Protein expression of nNOS in hippocampus of pigeon. A- Mean values (+ s.e.m.) of optical densitometric analyses of immunoreactive bands for nNOS in samples of hippocampal tissue homogenate normalized with Ponceau staining. Each mean was calculated with reference to the ZT0 value. The dashed line indicates the fitted curve by the Cosinor method. One-way ANOVA indicated group effects (p < 0.001); * indicates p < 0.05 when compared to ZT12, ZT16 and ZT20; # indicates p < 0.05 compared with ZT16 and ZT20 (Turkey-Kramer test; n = 4 pigeons per group). B- Representative immunoreactive bands for nNOS and proteins detected by Ponceau staining in each group.
