Molecular cloning and expression of a putative crustacean hyperglycemic hormone of Litopenaeus vannamei in Pichia pastoris
Provedor de dados: 69

Crustacean hyperglycemic hormone (CHH) is the most abundant and best studied member of the CHH/MIH/GIH neuropeptide hormone family. CHH plays a major role in controlling glucose levels in the hemolymph, and it also has significance in regulating molting, reproduction, and osmoregulation. In contrast, molt-inhibiting hormone (MIH) is responsible for maintaining animals in an intermolt stage. In this study, Liv-MIH-1 cDNA, which encodes a mature neuropeptide from the eyestalk of white shrimp, Litopenaeus vannamei, was expressed in methylotrophic yeast (Pichia pastoris KM71) under the control of an alcohol oxidase promoter. Recombinant Liv-MIH-1 was secreted into the culture medium using the &amp;#945;-factor prepro-sequence without Glu-Ala repeats. The...

Effects of serotonin and fluoxetine on blood glucose regulation in two decapod species
Provedor de dados: 56
Autores: Santos,E.A.; Keller,R.; Rodriguez,E.; Lopez,L.
One of the best known crustacean hormones is the crustacean hyperglycemic hormone (CHH). However, the mechanisms involved in hormone release in these animals are poorly understood, and thus constitute the central objective of the present study. Different groups of crustaceans belonging to diverse taxa (Chasmagnathus granulata, a grapsid crab and Orconectes limosus, an astacid) were injected with serotonin, fluoxetine, or a mixture of both, and glycemic values (C. granulata and O. limosus) and CHH levels (O. limosus) were determined after 2 h in either submerged animals or animals exposed to atmospheric air. Both serotonin and fluoxetine caused significant hyperglycemia (P&lt;0.05) after injection into the blood sinus of the two species, an effect enhanced...
