Molecular Response of Carbohydrate Metabolism to Dietary Carbohydrate and Acute Low Salinity Stress in Pacific White Shrimp Litopenaeus vannamei
Molecular response of carbohydrate metabolism in Litopenaeus vannamei was evaluated at transcriptional level through quantitative real-time PCR analysis. The mRNA expressions of six genes hexose-6-phosphotransferase, pyruvate kinase, phosphoenolpyruvate carboxykinase, crustacean hyperglycemic hormone, glucose transporter and insulin-like growth factors binding protein in the hepatopancreas, mus...
متن کاملOntogenetic variation in digestive proteinase activity, RNA and DNA content of larval and postlarval white shrimp Litopenaeus schmitti
Proteinase (endopeptidase), trypsin and chymotrypsin activities, RNA, and DNA contents were examined throughout the ontogenetic development of cultured Litopenaeus schmitti. Whole individuals from larval and postlarval stages, and adult hepatopancreas were homogenized and assayed for quantification of enzyme activity. Proteinase activity of different life stages was characterized by substrate-S...
متن کاملMolecular characterization of penaeidins from two Atlantic Brazilian shrimp species, Farfantepenaeus paulensis and Litopenaeus schmitti.
We report here the molecular cloning of new members of the penaeidin family from two Atlantic penaeids from Brazil, Litopenaeus schmitti and Farfantepenaeus paulensis. The presence of penaeidins in the granular hemocytes of both shrimps was first evidenced by immunofluorescence, using polyclonal antibodies raised against L. vannamei penaeidin Litvan PEN3-1. cDNAs from the hemocytes of both Braz...
متن کاملDietary effects of seaweed Sargassum ilicifolium on reducing cholesterol level of white leg shrimp (Litopenaeus vannamei)
In this research, the nutritional effects of Sargassum ilicifolium Chabahar Bay, Oman Sea, on cholesterol levels of white-leg shrimp (Litopenaeus vannamei) were studied. The seaweed was collected from coastal areas, rinsed, dried, powdered and the nutritional values were measured in the laboratory. A part of protein resources of shrimp feed replaced with seaweed powder in four treatments (D: as...
