Activation of peroxisome proliferator-activated receptor-gamma inhibits the Runx2-mediated transcription of osteocalcin in osteoblasts.
Mesenchymal cells are able to differentiate into several distinct cell types, including osteoblasts and adipocytes. The commitment to a particular lineage may be regulated by specific transcription factors. Peroxisome proliferator-activated receptor-gamma (PPARgamma), acting in conjunction with CCAAT/enhancer-binding protein-alpha, has been suggested as a key regulator of adipogenic differentia...
متن کاملDifferent Methylation Patterns of RUNX2, OSX, DLX5 and BSP in Osteoblastic Differentiation of Mesenchymal Stem Cells
OBJECTIVE Runt-related transcription factor 2 (RUNX2) and osterix (OSX) as two specific osteoblast transcription factors and distal-less homeobox 5 (DLX5) as a non-specific one are of paramount importance in regulating osteoblast related genes including osteocalcin, bone sialoprotein (BSP), osteopontin and collagen type Iα1. The present study sets out to investigate whether epigenetic regulatio...
متن کاملResveratrol Mediated Modulation of Sirt-1/Runx2 Promotes Osteogenic Differentiation of Mesenchymal Stem Cells: Potential Role of Runx2 Deacetylation
OBJECTIVE Osteogenic repair in response to bone injury is characterized by activation and differentiation of mesenchymal stem cells (MSCs) to osteoblasts. This study determined whether activation of Sirt-1 (a NAD(+)-dependent histone deacetylase) by the phytoestrogen resveratrol affects osteogenic differentiation. METHODS Monolayer and high-density cultures of MSCs and pre-osteoblastic cells ...
متن کاملBHE 014 The Interrelationship of Runx2 and Osx and Differentiation, Potential Therapeutic Implications
Non-viral based gene therapies represent one possible tissue engineering-based approach to improve bone regeneration. Unique target proteins for gene therapy are transcription factors. These are nuclear based proteins that can not feasibly be applied as mature proteins. Therefore, protein based therapies can not be utilized. Gene therapy is the only option. However, it remains unclear which tra...
متن کاملGenistein Promotion of Osteogenic Differentiation through BMP2/SMAD5/RUNX2 Signaling
To investigate the effects of Genistein on the osteogenic related gene expression profiles during osteoblastic differentiation of human bone marrow mesenchymal stem cell (hBMSC) cultures, the hBMSCs were cultured under osteogenic differentiation medium with the addition of Genistein (10(-8)∼10(-5) M) for 12 days. The cell proliferation was measured by BrdU incorporation, while the osteoblastic ...
