Outline of Final Research Achievements |
To clarify the role of elasmobranch ionocyte in osmoregulation, we used euryhaline bull shark as experimental fish. The transcriptome analyses were performed on bull shark gills, and we focused on CLC2, ECaC, and PMCA. ECaC expression was increased after FW acclimation. The distribution of CLC2 and PMCA signals were similar to that of ionocytes. These findings indicate that CLC2, ECaC and PMCA are involved in ionoregulation in the gills. Additionally, we examine the role of prolactin in bull shark. The results showed that prolactin and its receptor is highly expressed in pituitary.
