AIM To investigate the influence of Enterococcus faecalis lipoteichoic acid (LTA) on the key bone resorption-regulating proteins, receptor activator of nuclear factor-κB ligand (RANKL) and osteoprotegerin (OPG) in human periodontal ligament fibroblasts (PDL cells). METHODOLOGY Periodontal ligament cells were subjected to various concentrations of LTA. Cell viability was then determined by met...
INTRODUCTION This study investigated whether the calcineurin inhibitor, tacrolimus, suppresses receptor activator of NF-κB ligand (RANKL) expression in fibroblast-like synoviocytes (FLS) through regulation of IL-6/Janus activated kinase (JAK2)/signal transducer and activator of transcription-3 (STAT3) and suppressor of cytokine signaling (SOCS3) signaling. METHODS The expression of RANKL, JAK...
PURPOSE Increased bone resorption is a hallmark of multiple myeloma and is attributable to osteoclast activation. Recent studies showed that the receptor activator of nuclear factor kappaB ligand (RANKL) is the key mediator of osteoclastogenesis and plays a crucial role in bone destruction in malignant bone disease. We found that human myeloma cells express RANKL and analyzed the association of...
Interferon-stimulated gene 15 kDa (ISG15) is a protein upregulated by interferon-β that negatively regulates osteoclastogenesis. We investigated the role of ISG15 in receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclastogenic differentiation of murine RAW264 cells. RANKL stimulation induced ISG15 expression in RAW264 cells at both the mRNA and protein levels. Overexpression ...
Objective(s): This study aimed to determine the collagen type II (COL2) and SOX9 expression in interleukin growth factor (IGF-1)-induced Wharton’s Jelly mesenchymal stem cells (WJMSCs) and the level of chondrogenic markers in co-culture IGF1-WJMSCs and IL1β-CHON002 as osteoarthritis (OA) cells model. Materials and Methods: WJMSCs were induced with IGF1 (75, 150, and 300 ng/ml) to enhance their ...
objective(s): studies have reported that whole body vibration (wbv) played a vital role in bone remodeling. circulating serotonin is also involved in negative regulating bone mass in rodents and humans. however, both wbv and inhibition of serotonin biosynthesis may suppress receptor activator of nuclear factor-kappab ligand (rankl)-induced osteoclastogenesis in vitro . the purpose of the curren...
INTRODUCTION In osteoarthritis (OA) the progression of cartilage degeneration has been associated with remodeling of the subchondral bone. Human OA subchondral bone osteoblasts were shown to have an abnormal phenotype and altered metabolism leading to an abnormal resorptive process. Bone resorption is suggested to occur, at least in part, through the increased levels of two proteolytic enzymes,...
Receptor activator of nuclear factor kappa-B ligand (RANKL) expression was examined during the development of mouse fetal peripheral lymphoid organs. A shift in the expression pattern was detected during the transition from lymphoid tissue inducer (LTi) cells to lymphoid tissue organizer (LTo) cells in the lymph node (LN) anlagen but not in the Peyer's patch anlagen. In order to understand the ...
Osteosarcoma (OS) is the most common primary bone cancer, which occurs primarily in children and adolescents, severely affecting survivors' quality of life. Despite its chemosensitivity and treatment advances, long-term survival rates for OS patients have stagnated over the last 20 years. Thus, it is necessary to develop new molecularly targeted therapies for this metastatic bone cancer. Mutati...
BACKGROUND Osteoprotegerin (OPG), a soluble receptor of the tumour necrosis factor family, and its ligand, the receptor activator of nuclear factor-κB ligand (RANKL), are emerging as important regulators of vascular pathophysiology. OBJECTIVES We evaluated their effects on vasculogenesis induced by endothelial colony-forming cells (ECFC) and on neovessel formation in vivo. METHODS Effects o...
