| Research Abstract |
We have previously generated knockdown mice expressing shRNA of candidate genes involved in circadian rhythm regulation using a lentiviral vector. In this study, we further developed a technique to express two different shRNAs in vivo and successfully generated double knockdown mice. However, these mice exhibited significant individual differences in the knockdown efficiency and silencing effects among generations. Therefore, we next examined double knockout or cell type-specific knockout mice. Our data demonstrated abnormal circadian behavioral rhythms in different knockout mice strains and suggested involvements of novel candidate genes in the circadian clock machinery.
