| Outline of Final Research Achievements |
Post-transcriptional gene regulation such as mRNA processing, stability, and translation are controlled by microRNA (miRNA) and RNA binding proteins that predominantly bind to specific elements located in the untranslated regions (UTRs) of target mRNAs. miRNA binding to partially complementary site 3’-UTR of target mRNA. Several RNA binding proteins can interact with AU-rich elements.
The dental follicle contains stem cells and/or progenitor cells of the periodontium. Human dental follicle cells (hDFCs) have the ability to differentiation for osteoblasts and neural cells. hDFCs have great potential for utilized in regenerative cell therapy. In this study, we investigated miRNA and RNA binding proteins in hDFCs during differentiation for osteogenic or neural cells.
In addition, we examined that the IL-1β and TNF-α synergistic effect on GM-CSF and G-CSF expression in synovial cells are involved mRNA stability by RNA binding protein and AU-rich element in their mRNA 3’-UTR.
