A novel function of red pigment-concentating hormone in crustaceans: \kur{Porcellio scaber} (Isopoda) as a model species
ZRALÁ, Jana
The HPLC and LC/MS analyses of the CNS from isopod crustacean the woodlouse, Porcellio scaber revealed a presence of the red pigment-concentrating hormone (Panbo-RPCH) in this species. It has been shown that this neuropeptide plays a role in mobilization of energy stores: topical treatments of P. scaber individuals by Panbo-RPCH in a concentration 20 pmol/{$\mu$}l increased the level of glucose in haemolymph about 4 times. Glucose was the main carbohydrate mobilized by the Panbo-RPCH treatment. Despite the demonstration of hyperglycaemic activity of Panbo-RPCH, no stimulatory effect of this hormone on the locomotory activity of P. scaber was observed. The present study is the first discovery of an occurrence of Panbo-RPCH and its hyperglycaemic activity in the representative of the isopod crustacean.
