Annexins are a family of homologous proteins that associate with anionic phospholipid (aPL) in the presence of Ca(2+). Evidence that the function of one annexin type may be regulated by another was recently reported in studies investigating cytomegalovirus-aPL interactions, where the fusogenic function of annexin 2 (A2) was attenuated by annexin 5 (A5). This observation suggested that A2 may bi...

Eph receptors constitute the largest family of receptor tyrosine kinases. Multiple transcripts of ephrin-A5, the cognate ligand of the EphA3 receptor, were found in neonatal rat cardiomyocytes. Two cDNA clones encoding the full-length ephrin-A5 (ephrin-A5 alpha) and a 27-amino acid deletion form (ephrin-A5 beta) were isolated. To examine the role of ephrin-A5 in cardiomyocytes, the cDNAs were i...

The distribution and regulation of annexin A5 expression, a gonadotropin releasing hormone (GnRH) receptor regulated protein in gonadotropes and luteal cells, in the testes of rats were examined. Immunocytochemical staining revealed high levels of annexin A5 in the Leydig and endothelial cells and lower levels in the primary spermatocytes and sperm. Hemicastration significantly increased the an...

Auranofin has been developed as antirheumatic drugs, which is currently under clinical development for the treatment of chronic lymphocytic leukemia. Previous report showed that auranofin induced apoptosis by enhancement of annexin A5 expression in PC-3 cells. To understand the role of annexin A5 in auranofin-mediated apoptosis, we performed microarray data analysis to study annexin A5-controll...

AIM To investigate the expression of annexin A5 in serum and tumor tissue of patients with colon cancer and to analyze its clinical significance. METHODS Ninety-three patients with colon cancer treated at our hospital between February 2013 and March 2016 were included in an observation group, and 40 healthy individuals were included in a control group. Enzyme-linked immunosorbent assay was pe...
