Abstract

Two isoforms of crustacean hyperglycemic hormone (CHH) were identified in the blue crab, Callinectes sapidus.

  • The presence of structural CHH indicates complex physiological regulation in crustaceans.
  • Both isoforms of CHH were released in response to hypoxic conditions.
  • mRNA transcripts for the two CHHs showed differential regulation under stress: PO-CHH increased while ES-CHH decreased.
  • Much less is known about the functions of non-eyestalk CHH compared to those from the eyestalk.
