Definitions
- the present invention relates to a gonad-stimulating hormone derived from an invertebrate such as a starfish starfish and a method for producing the same.
- gonad-stimulating hormones in vertebrates that control the development of the gonad, the development of the egg's sperm, the release of 'maturation', and the like. Elucidation of gonadotropins in vertebrates such as fish is progressing. Their structural similarity is well preserved from fish to humans, and each is a heterodimeric protein hormone consisting of one ex subunit and one j8 subunit.
- Vertebrate gonad-stimulating hormone has been confirmed to have gonad-stimulating effects among vertebrates across species (Non-patent Document 1, Patent Documents 1 and 2), but has no effect on invertebrates. Invertebrate gonadotropins are not as well understood as vertebrate gonadotropins. It has been confirmed that gonad-stimulating hormone (GSS) is also extracted from the invertebrate starfish starfish (GSS) and induces ovulation of ovarian pieces (Non-patent Documents 2 and 3).
- GSS gonad-stimulating hormone
- This gonad-stimulating hormone is known to act on the follicular cells surrounding the egg in the ovary to newly synthesize and secrete an oocyte maturation-inducing hormone (1-methyladenine) that acts directly on the egg (non-patented). Reference 4).

Since then, the main source of extraction of gonadotropins in other types of invertebrates (other than starfish) has been neural tissue in that species. In addition, if there are tissues' organs that have been reported to have gonadotropic hormone action depending on the animal species, these may be used as the extraction source.

- the test individuals In order to use this short-term function, the test individuals must have eggs that are sufficiently developed to lay eggs. Individuals used for testing are in early spawning season It is preferable to collect and maintain vigorously in a laboratory water tank. Not all individuals that have been collected are mature enough to lay eggs. They can lay eggs, but their maturity levels are slightly different, and there are usually differences in hormone sensitivity among individuals. Therefore, in order to test gonad-stimulating activity, it is necessary to search for mature individuals (individuals with eggs that can lay eggs) and prepare multiple individuals with some degree of sensitivity to hormones. is there.
- Gonadal stimulating hormone stimulates follicular cells in the ovaries, which secrete another hormone, the “egg maturation-inducing hormone”, that acts on the egg, resulting in ovulation.
