RANKL Detection Service

The RANKL-RANK signaling pathway plays a key role in the development of osteoclasts and the regulation of the immune system. This signaling pathway not only works as a major mediator of osteoclast activation, formation and inventory, but also functions in breast, brain and lymph nodes. Disorders of the RANKL-RANK signaling pathway can lead to a variety of diseases, including postmenopausal osteoporosis, rheumatoid arthritis (RA), bone tumors, and certain bone metastatic tumors. Creative BioMart Biomarker is capable to provide our customers with superior RANKL detection service, various detection methods ensuring high sensitivity for detecting biomarkers in different samples with different concentrations.

Introduction

Receptor activator for nuclear factor kappa-B ligand (RANKL) is a member of the TNF receptor superfamily and is produced by osteocytes, pre-osteoblasts and endothelial cells. In the presence of macrophage colony-stimulating factor, RANKL binds to its receptor RANK, resulting in increased osteoclast formation and activity. In the late 1990s, it was discovered that the nuclear factor κB receptor activator ligand (RANKL) and its ligand (RANK) can induce osteoclastogenesis, while osteoprotegerin (OPG) acts as a soluble molecular decoy. The RANKL-RANK signaling pathway plays a key role in the development of osteoclasts and the regulation of the immune system. Stimulated by parathyroid (PYD) hormone, vitamin D or prostaglandin 2, osteoblasts and osteocytes present RANKL to osteoblast progenitor cells. OPG inhibits RANK signaling by preventing interactions between RANKL-RANK. Upon binding to RANKL, the RANK receptor undergoes trimerization and recruits a TRAF6 adaptor molecule that conjugates RANK to a variety of signaling pathways. c-Src activates anti-apoptotic signals via Akt/protein kinase B. Activation of MAPK induces translocation of c-Fos and c-Jun to the nucleus. The nuclear translocation of NF-κB up-regulate c-Fos, and the c-Fos and Ca2+-regulated NFATc1 complex initiates the genetic program required for osteoclast formation and maturation.
