[An exploration of animal behavior screen platform for novel gene function in central nervous system].
For the purpose of large-scale screening of novel gene functions in mammalian nervous system, we have developed an animal behavior-monitoring platform employing antisense-oligo technology. Twenty genes of different categories were chosen from a low abundant gene (c)DNA sub-library of rat brain. Antisense oligo-nucleotides of these genes were designed and synthesized according to the homologues of the genes in mouse for mouse behavior tests. These antisense oligos were injected into the lateral ventricles of mouse brain using a Hamilton micro-syringe, with saline and oligos of scramble sequences as controls. These mice were tested with the following behavior model paradigms: metabolism, open field behavior, tail flick latency, and step-down test. Out of the 20 genes tested, 14 genes showed significant behavioral differences from the control groups at the level of P value less than 0.05 or 0.001 in different behavior animal models.
