Research Abstract

In this study, Isolation of vitellogenesis-stimulating hormone (VSH) from the sinus glands of Maruspenaeus japonicus and Palaemon paucidens was conducted. In M. japonicus, a candidate molecule for VSH, which specifically increases in the sinus gland during vitellogenic stage, was purified. In P. paucidens, VSH has not yet been isolated, but vitellogenesis-inhibiting hormone (VIH) was successfully purified. In the near future, biological activities of the both stimulating and inhibiting hormones will be elucidated.
