| Outline of Final Research Achievements |
In order to preserve shark resources, we studied on the molecular endocrine mechanisms of oogenesis and spermatogenesis of sharks, using cloudy catshark as a model fish. We newly identified genes related to sexual maturation and eggshell formation, such as hypothalamus gonadotropin-releasing hormone, pituitary gonadotropins, collagen and collagen-converting enzymes of the oviducal gland. Physiological roles of some genes were clarified. Moreover, the morphological observation revealed the process of gonad sex differentiation and genes of steroid hormone metabolizing enzymes were identified.
