PEPTIDE HAVING OSTEOGENIC DIFFERENTIATION PROMOTION AND PERIODONTAL LIGAMENT FIBROBLAST ACTIVATION PROMOTION, AND USE OF SAME

摘要

A peptide comprising an amino acid sequence of SEQ ID NO: 1 or SEQ ID NO: 2, according to the present invention, shows proliferation and differentiation promotion of osteoblast and proliferation and activation promotion of periodontal ligament fibroblast. A peptide, according to the present invention, increases BMP signaling such as SMAD1/5/8 phosphorylation and increases the growth of osteoblast and the expression of a differentiation marker such as COL1A1, BSP and ALP, thereby ultimately showing osteoblast activation. A peptide, according to the present invention, promotes the growth of periodontal ligament fibroblast by means of PI3K and Akt phosphorylation and increases the expression of an activation marker such as COL1A1 and DSPP, thereby ultimately showing periodontal tissue regeneration activation. Provided are a composition for preventing or treating bone diseases and a composition for preventing or treating periodontal diseases, the compositions comprising the aforementioned peptide.
