Ovarian transcriptomics over a complete breeding cycle in wild Largemouth bass (Micropterus salmoides) characterizes pathways underlying oocyte maturation and atresia

ABSTRACT: Background: Follicular growth and maturation in semi-synchronously spawning fish involve numerous cell signaling cascades and different molecular cascades are activated or inhibited during specific stages of oocyte development. The objectives of the current study were to identify molecular pathways and temporal gene expression patterns throughout a complete breeding cycle in female wild LMB to characterize the molecular sequence of events underlying follicle and ovary development. Methods: Microarray analysis was performed on eight morphologically distinct stages, from primary stages of oocyte growth to ovulation and atresia. Ovarian tissue histology, plasma vitellogenin, and sex steroids (E2 and T) were also measured to correlate molecular signaling cascades to higher levels of biologica
