Research Abstract |
During their evolution, vertebrate animals had invaded the land from water. Blood calcium needs a constant concentration to maintain normal life activities. However, a number of organs do exist for calcium regulation among vertebrate animals, depending on calcium concentration and/or its distribution in a given environment. Using mice, zebrafish and Polypterus, one of living species representing common ancestors of ray-finned fishes (actinopterygians), we have investigated evolutionary effects of changes in a number of Gcm genes and their regulatory pathways on development and function of each organ. We have carried out a construction of conditional knockout mice, enhancer analyses of Gcm genes involved in the formation of zebrafish ionocytes, developmental analyses of external gills in Polypterus and comparative genomics of Gcm genomes.
