| Outline of Final Research Achievements |
The principal investigator conducted a suppressor screening to identify molecules involved in sleep regulation through the SIK3 pathway. We performed whole exosome sequencing to examine the frequency of random point mutations due to ethylnitrosourea dosage. We used SIK3 gene mutant mice of the C57BL/6N strain to induce random mutations and made them crossed with wild-type C57BL/6J females to obtain F1 mice. We examined sleep/wake behavior based on EEG/EMG recording of the F1 generation mice. Since there are many polymorphisms even in the same C57BL/6J or C57BL/6N strains from multiple breeders, we sequenced SNP candidates and created a full SNP panel that is necessary for a linkage analysis. I have been running a suppressor screening for sleep in mice.
