| Research Abstract |
The aim of this study is to investigate adaptive, reproductive and developmental physiologies of the cartilaginous fish by using elephant fish as a model organism, for which the public genome database is available. We have proposed a urea reabsorption model in the renal nephron by mapping of various transporting proteins for urea, water and ions. In the present study, we also found contribution of the yolk-sac membrane to body fluid regulation in the early developmental stages, and a novel neurohypophysial hormone receptor that is likely to be involved in the maintenance of homeostasis.
