Research Summary

Life science research makes use of toxic and deleterious substances and radioactive compounds that are harmful to the human body. Chemical and Radioisotope Management Unit is responsible for the management of hazardous chemicals and radioisotopes, in addition to the support of studies that take advantage of radioisotopes.

In Caenorhabditis elegans, sophisticated methods are available to determine gene expression patterns and to generate genetically modified strains, which are indispensable for reverse genetic analysis. Aiming at the elucidation of gene regulatory system, we study microRNAs, which serve as post-transcriptional regulators of gene expression. Our approaches are to develop novel methods for functional analysis, to identify target genes, and to unravel the physiological roles of microRNAs.

Survey meters and files used for the administration of radiation and radioisotopes.
