Oogenesis in Solea senegalensis: Previtellogenic versus vitellogenic ovaries

ABSTRACT: Transcriptionnal profile changes in ovary during the reproductive cycle of Solea senegalensis: from previtellogenic stage to vitellogenic stage obtained at different times during the annual reproductive cycle. An oligo microarray based on ESTs sequenced from S. senegalensis previously designed (Cerdà et al., 2008, BMC genomics) was used. The two stages of ovary development were directly compared using three individuals for each stage (IR-Pv-1, IR-Pv-2, IR-Pv-3 for previtellogenic individuals and IR-Vt-1, IR-Vt-2, IR-Vt-3 for vitellogenic individuals). For the experiment, the vitellogenic stage was used as the control.

<h4>Background</h4>The Senegalese sole (Solea senegalensis) is a marine flatfish of increasing commercial interest. However, the reproduction of this species in captivity is not yet controlled mainly because of the poor knowledge on its reproductive physiology, as it occurs for other non-salmonid marine teleosts that exhibit group-synchronous ovarian follicle development. In order to investigate intra-ovarian molecular mechanisms in Senegalese sole, the aim of the present study was to identify d  ...[more]
