  • Space experiment on the effect of microgravity on midge
    ~ Metamorphosis of midge in space environment ~

    An experiment on metamorphosis under microgravity was carried out by JAXA Austronaut Koichi Wakata at the Kibo laboratory of the International Space Station (ISS) using dry larvae of the sleeping chironomid (midge). The experiment is part of the Space Midge Project, a joint collaboration of the National Institute of Agrobiological Sciences (NIAS), the Russian Academy of Sciences Institute of Biomedical Problems (IBMP) and Russia’s Kazan Federal University (KFU), designed to determine the impact of the space environment on desiccation tolerance and gene expression of sleeping chironomid. Upon rehydration, the dry larvae absorbed water and were revived eventually to metamorphose into pupa and the imago stage two weeks later. This is the first study that an insect in the dry state has been shown to undergo metamorphosis under microgravity and indicates the usefulness of midge as experimental material in space biology particularly in understanding how the microgravity influences the genetic apparatus and life cycle of insects.

  • Towards improving artificial insemination efficiency in cattle
    ~ Elucidating the mechanism of luteal cell proliferation ~

    A joint study of Okayama University and NIAS led to the discovery for the first time of the mechanism involved in the growth and proliferation of luteal cells which control hormone secretion during pregnancy in cattle. During artificial insemination of cattle, the time of ovulation can be controlled by the dosage of the hormone, but it is necessary to wait until the luteal cells grow resulting in low efficiency. Understanding the relationship between luteal growth and cell proliferation could contribute to the improvement of the efficiency of artificial insemination in cattle in the future.

  • Identification of a new type semiochemical carrier protein that mediates chemical communication in ants
    ~ Towards the development of eco-friendly pesticides ~

    A new protein that plays crucial role in chemical communication and exchange of information among worker ants has been successfully identified. As this protein specifically functions on ants, this discovery is expected to provide a potential target for the development of safe and environmentally friendly agricultural pesticides against harmful and invasive ants.

  • Sex pheromone successfully controls sugarcane insect pest
    ~ Towards the development of an eco-friendly insect pest management strategy ~

    The mating behavior of white grub beetle (Dasylepida ishigakiensis), a major insect pest of sugar cane, has been successfully disrupted with the application of synthetic sex pheromone in the field. The sex pheromone released in the field using polyethylene-tube dispensers reduced the larval density of next generation thereby providing an effective and environment friendly method of preventing extensive damage in infestation caused by the insect pest.

  • Discovery of a leech that can survive extremely low temperature

    A joint research of NIAS and Tokyo University of Marine Science and Technology led to the discovery of a leech capable of surviving exposure to extremely low temperature. The leech can survive even after exposure to liquid nitrogen (-196oC) for 24 hours and frozen at -90oC for up to 32 months. In addition, the leech is capable of enduring more than 10 times of repeated freeze-thawing cycle ranging from 20 to -100°C.

  • Development of the technology to evaluate the function of a specific domain of intracellular protein
    ~ Towards the acceleration of functional analysis of intracellular protein ~

    Intracellular enzymatic proteins and regulatory proteins in gene expression consist of two or more domain with specific structure that exhibits their specific functions. Although the functions of intracellular proteins were analyzed by the loss of the gene expression, so called "gene-knockout", each domain function of proteins has not been fully investigated. In the present study, it has been demonstrated that intracellularly expressed antibodies (intrabodies) composed of only the variable regions (VH or VL) of antibodies retain their specific binding activity to the target protein and efficiently inhibit the domain function of intracellular protein. These results suggest that intrabody technology provides a novel approach to decipher the molecular mechanisms of protein function in the cell.
