Transcriptome profiling of dominant follicle development in the equine ovary

ABSTRACT: The Objective of this study was to establish global gene expression profiles associated with different stages of dominant follicle development in the horse. This was done by collecting ovaries at different stages of an ovulatory follicular wave, when the dominant follicle reached 22 mm (early dominant, ED), 33 mm (late dominant, LD) and 34 h after an i.v. injection of crude equine gonadotropins (CEG; 15 mg i.v.) when the largest follicle reached > 33 mm (preovulatory stage, PO). RNA was then separately collected from granulosa cells and theca-rich follicular wall fractions and was hybridized to the Agilent Horse Gene Expression Microarray. Gene expression was compared between ED and LD and between LD and PO stages within each of granulosa cells and theca walls. Significantly larger num
