Studies on the genetic programming of life cycle phases in Paramecium
Many organisms show sexual immaturity, maturity and senescence in their life cycles. How are the life cycle phases controlled? In Paramecium, the period of immaturity is genetically controlled. In our laboratory, we are studying the molecular mechanisms that are genetically programmed. We have found a fascinating molecule named Immaturin in young Paramecium by using a microinjection technique. Immaturin rejuvenates senescent cells to mature, and mature cells to immature ones upon microinjection. Immaturin is a small polypeptide and has a catalytic effect on DNA and double stranded RNA. Now, we are approaching the central question of genetic programming working in the regulation of life cycle phases in eukaryotic organisms. |

Our research concerns both fundamental and applied issues in the field of ecophysiology and ecotoxicology of aquatic living things, in particular, fish. Four following areas of research are presently being pursued in our laboratory.
(a) Integrated fish physiology : We are especially interested in the function and the control mechanism of excretory organs (kidney and gills) by circulating and localized hormones and nervous systems. In behalf of this research, respiratory and cardiovascular responses in fish exposed to various environmental conditions have been also investigated.
(b) Investigations of stress responses and fish diseases : We have mainly focuses on the stress response, behaviour, and health (bio-defense response) in teleost fish exposed to environmental pollutants and infected with various diseases.
(c) Fish otolith (calcified tissue) chemistry : Otolith composition of fish is being explored by using simultaneous multi-elemental analysis (PIXE and SIMS) methods for grasping the environmental history of fish habitat.
(d) Assessment of water environment and removal of pollutants. In addition to that, the advanced and multilateral use of resources : Investigations are ongoing.
(e) The sustainable supply of the safe food and water, and the development of the technique which specifies a production area : Investigations are ongoing. |

Hiroshi Sasaki
Doctor of Agriculture
I am focusing on achieving a better understanding of biological production by lower trophic organisms and material cycling processes in aquatic environments. In particular, my research has been done in coastal waters close to Ishinomaki and also in open cold waters, such as the Arctic and Antarctic Oceans. |

Many bivalve species have ingenious strategies for their reproduction. From this point of view, I am conducting research on the echological and physiological mechanisms of gametegenesis and spawning in marine bivalves. |

Deep-sea biology
The deep-sea is an extreme environment. Bivalves which thrive in deep-sea hydrothermal vents and cold seeps live in symbiosis with chemoautotrophic bacteria. My interest in the deep-sea is in how its inhabitants adapt to survive and flourish within it. |

Why are offspring young?
Many organisms have a finite lifespan, but when the organisms produce offspring through sexual reproduction, they can be rejuvenated and start a new generation. How are the organisms rejuvenated during sexual reproduction? I am studying to solve this problem using Paramecium. |

In the eukaryotic nucleus, a nucleosome contains two of each of the histones H2A, H2B, H3, and H4 as a basic building block of chromatin. Histones form an octamer with a protein core from specific interactions and the octamer is wrapped in DNA. I am investigating how the chromatin structure regulates the transcriptional activity of a gene. |

Seagrass and intertidal habitats are highly productive components of estuaries and coastal ecosystems and support diverse faunal assemblages. They are excellent habitats for many commercial fishes and also act as nurseries for juvenile fishes. However, seagrass and intertidal habitats around the world are declining as a result of human impact on coastal and estuarine environments. Thus, many restoration projects have been attempted either as mitigation for loss from development or as enhancement of fishery production. Many of them, however, have failed to maintain sustainable habitats.
The objective of my research is to clarify the factors responsible for the decline of seagrass and intertidal habitats. The ultimate goal of my research is to increase the success of their restoration efforts. |

Environmental Study of Fishery Resources on the Sanriku Coast
The coastal areas of Sanriku provide a favorable environment for the aquaculture of animal resources such as oysters, scallops, sea squirts and salmon. To preserve this environment, I am focusing on the ecological study of food organisms (plankton and seaweed) and parasites of creatures that have economic significance. |
