Fig. 3. Brn3b-dependent genes require Brn3b for expression only in the retina.
Shown here are four genes (A, Rgcg1; B, synaptotagmin 4; C,
persyn; D, Brn3a) whose expression was downregulated in the
RGC layer in Brn3b-null (-/-) when compared with the heterozygous
retina (+/-), but was not changed in other tissues. NC, nasal cavity; R,
retina; DRG, dorsal root ganglia; SC, spinal cord.
