| Outline of Final Research Achievements |
Crustacean vitellogenesis is regulated by vitellogenesis-inhibiting hormone (VIH) from the X-organ/sinus gland neurosecretory system in the eyestalks. To investigate the mode of action of VIH in the ovary, transcriptome and proteome analyses were performed. Transcriptome analyses revealed that several hormonal factors presumed to be involved in the regulation of vitellogenesis or development of secondary sex characteristics, suggesting that peripheral tissues contribute to the regulation of ovarian development. In addition, sex-lethal, piwi, and pumilio, which were involved in the regulation of the renewal and differentiation of germline stem cell in Drosophila, were identified by proteome analyses.
