Transcriptional profiling of the luteinizing hormone surge in bovine granulosa cells (GC) during the pre-ovulation period comparing 2 h pre-LH GC, 6 h post-LH GC and 22 h post-LH GC

ABSTRACT: The LH surge induces panoply of events that are essential for ovulation and corpus luteum formation. The transcriptional responses to the LH surge of pre-ovulatory granulosa cells are complex and still poorly understood. In the present study, a genome wide bovine oligo array was used to determine how the gene expression profiles of granulosa cells are modulated by the LH surge. Granulosa cells from three different statuses were used (1) 2 h before the induction of the LH surge, (2) 6 h and (3) 22 h after the LH surge to assess the short and long term effects of this hormone on follicle differentiation. The results obtained were a list of differentially expressed transcripts for each granulosa cell group. To provide a comprehensive understanding of the processes at play, biological annotati
