The aim of this study was to investigate the effects of apelin on proliferation and apoptosis of mouse osteoblastic MC3T3-E1 cells. APJ was expressed in MC3T3-E1 cells. Apelin did not affect Runx2 expression, alkaline phosphatase (ALP) activity, osteocalcin and type I collagen secretion, suggesting that it has no effect on osteoblastic differentiation of(More)
The domestic pig has been widely used as an important large animal model. Precise and efficient genetic modification in pig provides a great promise in biomedical research. Recently, clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated (Cas) system has been successfully used to produce many gene-targeted animals. However,(More)
OBJECTIVES Apelin is a recently discovered peptide that is the endogenous ligand for the orphan G-protein-coupled receptor APJ. Adipocytes can express and secrete apelin. The aim of this study was to characterize apelin and APJ expression in human osteoblasts and to investigate the effects of apelin on osteoblasts. RESULTS Apelin and APJ were expressed in(More)
Mesenchymal stem sells (MSCs) have received much attention in the field of bone tissue engineering due to their biological capability to differentiate into osteogenic lineage cells. Hypoxia-inducible factor 1alpha (HIF-1α) plays an important role in the MSC-related bone regeneration during hypoxia, while core binding factor alpha 1 (Cbfα1) is a(More)
Objectives: Apelin is a recently discovered peptide that is the endogenous ligand for the orphan G-protein-coupled receptor APJ. Adipocytes can express and secrete apelin. Osteoblast can express apelin and APJ. The aim of this study was to investigate the action of apelin on apoptosis of human osteoblasts. Results: Apelin inhibited human osteoblasts(More)
Pigs share many physiological, biochemical, and anatomical similarities with humans and have emerged as valuable large animal models for biomedical research. Considering the advantages in immune system resemblance, suitable size, and longevity for clinical practical and monitoring purpose, SCID pigs bearing dysfunctional RAG could serve as important(More)
OBJECTIVE To investigate the effect of osteogenic growth peptide(OGP) to the proliferation and differentiation of osteoblast-like cells in vitro. METHODS Calvarial osteoblast-like cells of rat bones were cultured individually in medium contained various concentrations (10(-11) mol/L-10(-7) mol/L) of OGP; and the cell proliferation was checked by MTT(More)
Mutations in the human copper/zinc superoxide dismutase 1 (hSOD1) gene cause familial amyotrophic lateral sclerosis (ALS). It remains unknown whether large animal models of ALS mimic more pathological events seen in ALS patients via novel mechanisms. Here, we report the generation of transgenic pigs expressing mutant G93A hSOD1 and showing hind limb motor(More)
