| Outline of Final Research Achievements |
We aimed to determine gene expression patterns in the anterior pituitary (AP) of heifers before and after ovulation via deep sequencing of the transcriptome (RNA-seq) to identify new genes and clarify important pathways. The bovine APs expressed 12,769 annotated genes at pre- or post-ovulation. The bovine AP showed differential expression of 396 genes (P<0.05) in the pre- and post-ovulation APs. The 396 genes included new G-protein-coupled receptor (GPCR) genes and binding proteins. The AP also expressed 259 receptor and other 364 binding proteins. Moreover, ingenuity pathway analysis for the 396 genes revealed a canonical pathway linking GPCR to gene expression. Thus, the present study clarified the novel genes found to be differentially expressed before and after ovulation and clarified an important pathway in the AP. Some of the new GPCR colocalizes with GnRH receptor on the lipid raft in the plasma membrane of gonadotrophs.
