Bone destruction and inflammation are closely linked. Cytokines play an important role in inflammatory bone destruction by upregulating the receptor activator of nuclear factor-κB (NF-κB) ligand (RANKL). The direct role of cytokines that act in a non-RANKL-dependent manner has yet to be elucidated. The aim of this study was to investigate the direct osteoclastogenic properties of inflammatory c...
CONTEXT The receptor activator of nuclear factor kappaB ligand (RANKL) is essential for osteoclast and, possibly, osteoblast activation and may represent a key link between bone formation and resorption. OBJECTIVE To determine the relationship between serum level of RANKL and the risk of nontraumatic fracture. DESIGN, SETTING, AND PARTICIPANTS As part of a prospective population-based study...
BACKGROUND Metastases to bone are a frequent complication of human prostate cancer and result in the development of osteoblastic lesions that include an underlying osteoclastic component. Previous studies in rodent models of breast and prostate cancer have established that receptor activator of NF-kappaB ligand (RANKL) inhibition decreases bone lesion development and tumor growth in bone. RANK ...
In the current report, we investigated the possibility of a cross-talk between receptor activator of NF-kappaB ligand (RANKL) and tumor necrosis factor alpha (TNF-alpha) using macrophage cell lines derived from wild-type mice and from mice with genetic deletion of the type 1 TNF receptor (p60(-/-)), the type 2 TNF receptor (p80(-/-)), or both receptors (p60(-/-)p80(-/-)). Deletion of TNF recept...
مالتیپل میلوما بیماری ای خونی است که در آن میزان زیادی پلاسماسل تولید می شود.tgf سایتوکاینی است که به میزان زیادی درماتریکس استخوان یافت می شود. به نظر می رسد نقش اصلی tgf? در تشکیل استئوکلاست به واسطه افزایش حساسیت پیش سازهای استئوکلاست به rankl می باشد. در این پایان نامه اثر tgf? بر روی بیان ژن rank بررسی شده است.
BACKGROUND Glomerulosclerosis correlates with reduction in podocyte number that occurs through mechanisms which include apoptosis. Podocyte injury or podocyte loss in the renal glomerulus has been proposed as the crucial mechanism in the development of glomerulosclerosis. However, the mechanism by which podocytes respond to injury is poorly understood. TNF and TNF receptor superfamilies are imp...
Receptor activator of nuclear factor κ B ligand (RANKL) plays a crucial role in the bone erosion of rheumatoid arthritis (RA) by prompting osteoclastogenesis. Considering that 1,25(OH)2D3 has been suggested as a potent inducer of RANKL expression, it should clarify whether vitamin D supplement could result in RANKL overexpression and thereby facilitate excessive osteoclastogenesis and bone reso...
The tumor necrosis factor superfamily (TNFSF) members play pivotal roles in embryonic development of lymphoid tissue and their homeostasis. RANKL (Receptor activator of NF-κB ligand, also called TRANCE, TNFSF11) is recognized as an important player in bone homeostasis and lymphoid tissue formation. In its absence bone mass control is deregulated and lymph nodes fail to develop. While its functi...
STAT5 is a key transcription factor for IL-3-mediated inhibition of RANKL-induced osteoclastogenesis
Among the diverse cytokines involved in osteoclast differentiation, interleukin (IL)-3 inhibits RANKL-induced osteoclastogenesis. However, the mechanism underlying IL-3-mediated inhibition of osteoclast differentiation is not fully understood. Here we demonstrate that the activation of signal transducers and activators of transcription 5 (STAT5) by IL-3 inhibits RANKL-induced osteoclastogenesis...
INTRODUCTION NSCLC is the leading cause of cancer mortality. Recent retrospective clinical analyses suggest that blocking the receptor activator of NF-κB (RANK) signaling pathway inhibits the growth of NSCLC and might represent a new treatment strategy. METHODS Receptor activator of NF-κB gene (RANK) and receptor activator of NF-κB ligand gene (RANKL) expression in human lung adenocarcinoma w...
