| Summary |
Cholesteatoma arises from a tympanic membrane and expands in the middle ear. It erodes the surrounding bone and leads to hearing loss or brain abscess which is lethal complication. Currently, the only effective treatment is the complete surgical removal of cholesteatoma. However, possibility of recurrence is not satisfactory, other clinical treatment is desired. A mechanism of bone erosion in rheumatoid arthritis, which is one of the bone destructive disease, is progressing to be clarified. Receptor activator of NF-κB ligand (RANKL) secreted by synovial fibroblasts, T cells, and B cells lead to differentiation and activation of osteoclast precursor in rheumatoid arthritis. In contrast it has been still unclear why cholesteatoma erodes bone. In the current study we studied that osteoclasts statistically increased in cholesteatoma, and that fibroblasts in the prematrix of cholesteatoma express RANKL. In this study we studied that osteoclasts statistically increased in cholesteatoma, and that fibroblasts in the prematrix of cholesteatoma express RANKL. We investigated upstream of RANKL from RNA sequence results by Ingenuity Pathways Analysis, which is data base of abundance information about molecular biology.

| Overall design |
To generate the transcriptome profiles of the permatrix of cholesteatoma and dermis cut by laser micro dissection from cholesteatoma, three pairs of both sample from the same patients were adapted to RNA sequencing.
