IR kinase is downregulated with unilateral naris occlusion. A: postnatal day 10 animal after left unilateral naris occlusion 24 h after birth. Note the slightly reduced size of the left olfactory bulb. B: 10-micron-thick cresyl violet stained cryosection of a postnatal day 10 animal after naris occlusion as in A. Shown is the control (right olfactory bulb, contralateral to occlusion) versus the naris-occluded (left olfactory bulb, ipsilateral to occlusion) cryosection at ×10 magnification. Note the apparent reduction in the ONL, disordered (and often missing in many sections) glomeruli, reduced thickness of the EPL, and lack of demarcation between the MCL and the GCL in the naris-occluded cryosection. Bar = 100 μm. C: 10-micron cryosections of a postnatal day 30 animal after naris occlusion as in A. Control and naris-occluded conditions were double-immunolabeled with anti-β tubulin III (1:300) and IR kinase (1:100) as indicated. Bar = 15 μm. Abbreviations as in Fig. 7.
