A PRND polymorphism in Churra do Campo portuguese sheep breed

Prion-like Doppel gene (PRND) is located downstream from priori protein gene (PRNP). Doppel protein is not related to prion disease but to male fertility. Our previous analysis of PRND coding region in 460 animals from 8 Portuguese sheep breeds, by multiple restriction fragment-single strand conformation polymorphism (MRFSSCP), revealed a synonymous substitution (78G>A). An association was found between identif...

Cyclooxygenase-2 (COX-2) expression by in vitro produced bovine embryos. Prelim...

Expression of the two isoforms of cyclooxygenase enzyme, cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), by in vitro produced bovine embryos was examined. Cumulus-oocyte complexes were recovered from ovaries of slaughtered animals and subsequently in vitro matured and in vitro fertilized. Presumptive zygotes were cultured in serum containing medium (TCM 199+10% bovine superovulated oestrus serum) on a gr...
