Transcription profiling of chicken oocytes to determine impact of oocyte competence on subsequent fertility

ABSTRACT: The aim of this study was to assess the impact of oocyte competence on subsequent fertility. Based on knowledge already accessible in mammals and on bioinformatics tools including the chicken genome sequence, we focused on the expression of genes involved in the processes of fertilization and of early embryo development. A differential kinetic study is performed on INRA lines selected on the basis of their fertility potential in purpose of hopefully access gene markers of fertility performance. We use 4 different hen lines:; - one line of laying hens with 3 different samples: the just ovulated oocyte, the oocyte collected 24 hours before ovulation (F1 stage), and granulosa cells collected at the F1 stage. We could compare different tissue and developmental stages. - one line of hen wit
