| Outline of Final Research Achievements |
We performed functional analysis of DHRS3, CYP26A1 and NR0B1, highly expressed in favorable neuroblastoma transfected into neuroblastoma cell lines such as SKNSH, NH12, TGW, GOTO and NH6 with an overexpression and silensing system. DHRS3 and NR0B1 induced cell proliferation, cell cycle suppression, decreased tumorigenic ability.
In exhaustive transcriptome analysis using RNAseq, expression of genes related to cell cycle and cell proliferation was decreased. We found the group of genes involved in the suppression of TGF-βsignaling involved in the retinoid X receptor activation pathway, JNKsignaling, tumor suppression and promotion of tumor growth. Therefore, DHRS3 and NR0B1 may be associated with spontaneous degeneration of neuroblastoma.
