P-Elk-1 staining in other areas of the hamster brain. A, P-Elk-1 staining in the SCN was always found to be nuclear, with no discernable dendritic or axonal staining present (section from CT19, light pulse given CT18–18.5).B, Adjacent section to that shown in A, but primary antiserum was adsorbed with phosphorylated Elk-1 peptide. This treatment abolishes P-Elk-1 staining. C, P-Elk-1 staining in the hamster parietal cortex. Here the P-Elk-1 staining is seen to be mostly dendritic and axonal in character, with only faintly stained nuclei present, most notably in layers I, II, and III.D, P-Elk-1 staining in hippocampal CA1. Similar to the cortex, P-Elk-1 staining in the hippocampus is dendritic and axonal in character, present most notably in the stratum radiatum (SR). Weakly stained nuclei are present in the stratum pyramidale (SP).E, P-Elk-1 in the intergeniculate leaflet (IGL). The IGL is part of the geniculate complex and is known to play a part in circadian time keeping in mammals. P-Elk-1-ir was present in the nuclei of IGL cells. P-Elk-1 levels in the IGL were not affected by photic conditions or by circadian phase. Scale bar: (in A)A–E, 15 μm.
