| Research Abstract |
I constructed a screening system based on RNA interference(RNAi) to identify a gene responsible for mental retardation in Down syndrome(DS). I identified an aggregation-like CaMKII in primary neurons as a useful marker for screening. If the maker is changed by specific gene knockdown, the target gene could be a candidate one responsible for DS. To assess whether the screening system run or not, I performed a test for the screening system using Rcan1 gene that could be associated with CaMKII. The result of screening showed that specific inhibition of Rcan1 gene tends to decrease in a rate of neurons with aggregation-like structure of CaMKII. The method of screening should be improved some points, and a candidate gene responsible for DS could be found by this screening system.
