| Outline of Final Research Achievements |
We analyzed DNA methylation levels of the top five regions, which showed hypomethylation in methylome-wide association study in schizophrenia(SZ), using the large sample consisted of peripheral blood of bipolar disorder(BD) patients and healthy controls(CT).
Among the five regions, significant differences of DNA methylation level between BD and CT were detected in the three regions; FAM63B, TBC1D22A and intergenic region in ch16. Detailed analysis focusing on sex revealed the hypomethylation in intergenic region in ch16 in both male and female BD, and hypomethylation in FAM63B in male BD. On the other hand, we identified hypermethylation of the CpG sites in TBC1D22A in female BD.
We identified common and distinctive epigenetic alterations between BD and SZ. These findings help to understand the pathophysiology of mental disorders and may contribute to develop the epigenetic-based biomarker using peripheral blood samples.
