Última No evidence of association of MUC-1 genetic polymorphism with embryo implantation failure BJMBR Dentillo,D.B.; Souza,F.R.P.; Meola,J.; Vieira,G.S.; Yazlle,M.E.H.D.; Goulart,L.R.; Martelli,L.. Pregnancy loss can be caused by several factors involved in human reproduction. Although up to 50% of cases remain unexplained, it has been postulated that the major cause of failed pregnancy is an error of embryo implantation. Transmembrane mucin-1 (MUC-1) is a glycoprotein expressed on the endometrial cell surface which acts as a barrier to implantation. The gene that codes for this molecule is composed of a polymorphic tandem repeat of 60 nucleotides. Our objective was to determine if MUC-1 genetic polymorphism is associated with implantation failure in patients with a history of recurrent abortion. The study was conducted on 10 women aged 25 to 35 years with no history of successful pregnancy and with a diagnosis of infertility. The control group...

Mol. Biol. Marques,V. Alonso; Goulart,L.R.; Silva,A.E.D. Feliciano. Just as calcium plays an integral role in acrosome capacitation and reaction, several spermatozoon proteins have been reported as binding to the ovum at fertilization. We examined the relationship between thawed bovine semen protein profiles, seminal plasma calcium ion concentration, spermatozoon phospholipase A2 (PLA2) activity and acrosome reaction. Electrophoretic profile analysis of spermatozoa and bovine seminal plasma proteins (total and membrane) revealed qualitative and quantitative differences among bulls. Variations in PLA2 and seminal plasma calcium concentration indicated genetic diversity among individuals. A 15.7-kDa membrane protein was significantly correlated (r = 0.71) with acrosome reaction, which in turn has been associated with in vivo...
