Abstract

Canaries and other songbirds offer unique advantages for analyzing the relationship between specific gene regulation and neural plasticity. To establish a quantitative profile of the population of RNAs potentially involved in this regulation, we analyzed the solution hybridization kinetics of canary forebrain cytoplasmic polyadenylated RNA. Hybridization of forebrain cDNA to forebrain RNA provides evidence for RNA species at individual concentrations ranging from less than 10(-6) to about 10(-3) (by fractional mass). Cross-hybridization to RNA from the rest of the brain, together with other studies, defines a subpopulation of about 5000 rare RNAs that are enriched in the forebrain compared to the rest of the brain. Some of these forebrain-enriched RNAs are likely to play a role in regulating the neural plasticity characteristic of the canary forebrain.
