| Outline of Final Research Achievements |
The aim of this study was to elucidate pathophysiology of inclusion body myositis by comprehensive expression profiling. Seventy-nine samples (11 controls, 11 PM, 47 IBM and 10 non-PM, non-IBM MHC-1 complex positive cases) were subjected to RNA-seq analysis. Seventy-one cases, of which RIN were more than 5, were statistically analyzed. Cluster analysis suggested that there was correlation between morphological classification and expression profile cluster. In IBM expression of cell adhesion molecules, inflammatory system, autophagy-lysosome system, and splicesome system were up-regulated. Expression of oxidative phosphorylation, citric cycle and electron transport genes was down-regilated.
