Circadian regulation of melanization and prokineticin homologues is conserved in the brain of freshwater crayfish and zebrafish.

Circadian clock is important to living organisms to adjust to the external environment. This clock has been extensively studied in mammals, and prokineticin 2 (Prok2) acts as one of the messenger between the central nervous system and peripheral tissues. In this study, expression profiles of Prok1 and Prok2 were investigated in a non-mammalian vertebrate… CONTINUE READING
