Osteoblastic differentiation of stromal ST-2 cells from octacalcium phosphate exposure via p38 signaling pathway

Rap1A Regulates Osteoblastic Differentiation via the ERK and p38 Mediated Signaling

Rap1A is a member of small G proteins belonging to the Ras family. Recently, an integration of human genome-wide association studies (GWAS) and gene expression profiling study revealed that single-nucleotide polymorphisms (SNPs) within human Rap1A were strongly associated with narrow neck width in women. However, the regulatory role of Rap1A in osteoblasts remains to be elucidated. Here we repo...

Curcumin promotes osteogenic differentiation of periodontal ligament stem cells through the PI3K/AKT/Nrf2 signaling pathway

Objective(s): The aim of this study was to investigate the effect of curcumin on the osteogenic differentiation of human periodontal ligament stem cells (hPDLSCs) and its underlying potential mechanism.Materials and Methods: The tissue explant adherence method was used to isolate hPDLSCs. Flowcytometry, Alizarin Red staining and Oil Red ...

Simvastatin enhances bone marrow stromal cell differentiation into endothelial cells via notch signaling pathway.

Bone marrow stromal cells (BMSCs) are capable of differentiating into multiple cell lineages including endothelial cells. Simvastatin, an HMG-CoA reductase inhibitor that is used as a cholesterol-lowering agent, promotes endothelial differentiation from epithelial progenitor cells (EPC). The Notch signaling pathway, which plays a key role in multiple cell functions such as differentiation, prol...

All-trans Retinoic Acid Regulates the Balance of Treg-Th17 Cells through ERK and P38 Signaling Pathway

Nanocurcumin-Mediated Down-Regulation of Telomerase Via Stimulating TGFβ1 Signaling Pathway in Hepatocellular Carcinoma Cells

Background: Curcumin, extracted from turmeric, represents enormous potential to serve as an anticancer agent. Telomerase is viewed as a prominent molecular target of curcumin, and transforming growth factor-β1 (TGFβ1) has proven to be a major inhibitory signaling pathway for telomerase activity. In the current study, we aimed to explore suppressive effects of nanocurcumin on telomeras...
