Coxsackie virus and adenovirus receptor, CXADR (CAR) is a member of the tight junction protein (TJP also known as JAM) family of adhesion receptor and located on a cytoplasmic membrane surface of intercellular tight junctions. CXADR are reported to be expressed during preimplantation in human embryos, but its function in early embryo development was not investigated. In the present study we determine temporal and spatial expression patterns of CXADR in porcine embryos and inve...

Introduction: Zinc is an extremely important trace element that play important roles in several biological processes. In this study, we investigated the role of zinc during meiotic resumption and metaphase arrest in in vitro-matured porcine oocytes.Materials and methods: Oocytes which arrest at GV or MII stage were treated with TPEN, a Zn2+ chelator, respectively. Meiotic resumption and activation were assayed. Effect of PMA, a PKC ac...
