BACKGROUND Cyclophilin A (CypA) is associated with metastasis in diverse cancers; however, its role in lung cancer metastasis and the underlying mechanisms remain poorly understood. Our study investigated the effect of CypA on non-small cell lung cancer (NSCLC) metastasis in vitro and in vivo to determine its mechanisms. METHODS In this study, A549 and H1299 cell lines with downregulated and ...
AIMS Cyclophilin A (CyPA) is a pro-inflammatory mediator involved in oxidative stress-related cardiovascular diseases. It is secreted from vascular smooth muscle cell (VSMC) in response to reactive oxygen species (ROS) in a highly regulated manner. Extracellular CyPA activates VSMCs and endothelial cells (ECs) promoting inflammation, cell growth, and cell death. Recently, it was shown that acet...
OBJECTIVE Cyclophilin A (CyPA) is secreted under inflammatory conditions by various cell types. Whereas the important role of intracellular CyPA for platelet function has been reported, the effect of extracellular CyPA on platelet function has not been investigated yet. APPROACH AND RESULTS Inhibition of extracellular CyPA through a novel specific inhibitor MM284 reduced thrombus after ferric...
Cyclophilin A (CypA) is a key member of immunophilins that has peptidyl-prolyl cis/trans isomerase (PPIase) activity. Besides acting as a cellular receptor for immunosuppressive drug cyclosporine A (CsA), CypA is involved in various cellular activities. CypA has an important role in viral infection which either facilitates or inhibits their replication. Inhibition of CypA via inhibitors is usef...
OBJECTIVE Oxidative stress and inflammation play key roles in the development of pulmonary arterial hypertension (PAH). Cyclophilin A (CypA) is secreted in response to oxidative stress and promotes inflammation and cardiovascular disease. Endothelial cell (EC) dysfunction is an early event in the pathogenesis of PAH. We evaluated the role of extracellular CypA in PAH and compared the effects of...
Cyclophilin A (CypA) is the main member of the immunophilin superfamily that has peptidyl-prolyl cis-trans isomerase activity. CypA participates in protein folding, cell signaling, inflammation and tumorigenesis. Further, CypA plays critical roles in the replication of several viruses. Upon influenza virus infection, CypA inhibits viral replication by interacting with the M1 protein. In additio...
Cyclophilin A (CypA) is a typical member of the cyclophilin family of peptidyl-prolyl isomerases and is involved in the replication of several viruses. Previous studies indicate that CypA interacts with influenza virus M1 protein and impairs the early stage of the viral replication. To further understand the molecular mechanism by which CypA impairs influenza virus replication, a 293T cell line...
Cyclophilin A (CypA), a receptor for the immunosuppressive agent cyclosporin A, is a cis-trans-peptidyl-prolyl isomerase (PPIase). It accelerates the cis-trans isomerization of prolyl-peptide bonds. CypA binds and regulates the activity of a variety of proteins. Atrial natriuretic factor (ANF) and its receptor membrane-bound guanylate cyclase-A (GC-A) are involved in the regulation of blood pre...
Cyclophilin A (CyPA; encoded by Ppia) is a ubiquitously expressed protein secreted in response to inflammatory stimuli. CyPA stimulates vascular smooth muscle cell migration and proliferation, endothelial cell adhesion molecule expression, and inflammatory cell chemotaxis. Given these activities, we hypothesized that CyPA would promote atherosclerosis. Apolipoprotein E-deficient (Apoe(-/-)) mic...
Cyclophilin (Cyp) belongs to a group of proteins that have peptidyl-prolyl cis-trans isomerase (PPIase) activity. CypA is the major cellular target for the immunosuppressive drug cyclosporin A and mediates its actions. Previous studies have demonstrated that CypA has diverse cellular functions and have suggested that CypA may function as an antioxidant. The present study investigated the antiox...
