OPG/RANK/RANKL signaling system and its significance in nephrology.

چکیده
Recent years brought the discovery of new members of TNF receptor superfamily - osteoprotegerin/receptor activator of nuclear factor-kappaB and its ligand (OPG/RANK/RANKL) system as regulator of bone remodeling. Further studies showed its involvement in control of vascular and immune system. Animal studies' results confirm the OPG/RANK/RANKL role in pathogenesis of vascular calcifications and osteoporosis. Human studies, especially in patients with chronic kidney disease (CKD), have brought many conflicting data. Understanding of exact contribution of each molecule creating this axis may be crucial for diagnosis and treatment of CKD complications involving renal osteodystrophy and vascular calcification. In this review we try to summarize recent knowledge and OPG/RANK/RANKL role in patient with chronic kidney diseases.

OPG/RANKL/RANK axis is a critical inflammatory signaling system in ischemic brain in mice.
Osteoprotegerin (OPG) is a soluble secreted protein and a decoy receptor, which inhibits a receptor activator of nuclear factor κB (NF-κB) ligand (RANKL)/the receptor activator of NF-κB (RANK) signaling. Recent clinical studies have shown that a high-serum-OPG level is associated with unfavorable outcome in ischemic stroke, but it is unclear whether OPG is a culprit or an innocent bystander. He...

The discovery of the receptor activator of nuclear factor-kappaB ligand (RANKL)/RANK/osteoprotegerin (OPG) system and its role in the regulation of bone resorption exemplifies how both serendipity and a logic-based approach can identify factors that regulate cell function. Before this discovery in the mid to late 1990s, it had long been recognized that osteoclast formation was regulated by fact...

OBJECTIVE To investigate the role of microRNA-145 (miR-145) in steroid-induced necrosis of the femoral head (SINFH) by evaluating its effects on the OPG/RANK/RANKL signaling pathway. METHODS A rat model of SINFH was constructed via injection of the lentiviral vector pLV-shRNA-miR-145. Pathological observation was performed via tartrate-resistant acid phosphatase (TRAP) staining, and serum OPG...

The present study examined the effects of brucine on the OPG/RANKL/RANK signaling pathway for exploring the mechanism of brucine suppression of bone metastasis in breast cancer. MDA-MB-231 breast cancer cells and mouse osteoblast MC3T3-E1 cells were cocultured to mimic the breast cancer bone metastasis microenvironment in vitro. qRT-PCR and Western blotting were used to detect the expressions o...
