Calcium-binding proteins play essential roles in the cell. One important class of calcium-binding proteins is the annexin family. This is a family of 13 proteins, which binds to phospholipids in a calcium-dependent manner. Osteosarcoma cell line (MG-63) is a transformed cell that has many characteristics of the differentiated cell, such as a considerable serum dependency in its growth rate. Usi...

objective: it is a firm belief that blood transfusion is life-saving in many situations, but at the same time transfusion complications could be life-threatening. the possible effects of blood transfusion related immunomodulatory (trim) and its related mechanisms is one of the important debatable subjects in the field of blood transfusion medicine. one of the mechanisms through which transfus...

introduction: apoptosis is a major consequence of ionizing radiation in proliferative tissues and quantification of the apoptotic cells could be helpful for noninvasive assessment and estimation of the radiation absorbed dose. annexin v conjugated with super paramagnetic iron oxide nanoparticles (anx-spio) is a biological probe for detection of apoptotic cells using magnetic resonance imaging. ...

It has been widely accepted that microparticles expose phosphatidylserine which in turn binds annexin V. It was the objective of this study to compare the antigenic characteristics and phospholipid-dependent procoagulant activity of annexin V positive and -negative subpopulations of platelet-derived microparticles. Annexin V positive and -negative microparticles were identified and characterise...

Platelets bind annexin V when stimulated with combinations of platelet agonists such as collagen and thrombin. Previous studies have demonstrated significant heterogeneity of platelets binding annexin V. The relative role of the thrombin protease-activated receptors (PARs), PAR1 and PAR4, together with different methods of platelet preparation on annexin V binding to platelets is unclear. We th...

The causes underlying the self-perpetuating nature of idiopathic pulmonary fibrosis (IPF), a progressive and usually lethal disease, remain unknown. We hypothesised that alveolar soluble annexin V contributes to lung fibrosis, based on the observation that human IPF bronchoalveolar lavage fluid (BALF) containing high annexin V levels promoted fibroblast involvement in alveolar epithelial wound ...

When the cell membrane is disturbed, phospholipid phosphatidylserine (PS) is translocated from the inner to the outer leaflet of the plasma membrane. This is one of the earliest signs of apoptosis and can be monitored by the calcium-dependent binding of annexin V. Therefore, annexin V-binding, in conjunction with flow cytometry, was used to evaluate the integrity of the sperm plasma membrane af...
