Diet-related plasticity of the digestive proteolytic system in larvae of the Colorado potato beetle (Leptinotarsa decemlineata Say)

“…Twenty micrograms of insect protein was loaded in each well. et al, 1977;Schick et al, 1984;Giorgi et al, 1985;Graf and Briegel, 1989;Corring et al, 1989;Barillas-Mury et al, 1991;Lhoste et al, 1993), the insect seems to adjust its digestive proteolytic system to the diet, both quantitatively and qualitatively. As shown on gelatin-containing gels, CPB larvae use a complex set of proteinase forms present in varying amounts depending on the diet.…”

Mesure de la digestibilité des protéines par la méthode des différences porto-artérielles chez l’espèce porcine

“…Ainsi, une quantité non négligeable d'azote endogène est sécrétée dans la lumière intestinale et mélangée avec l'azote alimentaire au cours de la digestion. L'importance de cette sécrétion dépend en outre de la nature des constituants des repas, des niveaux énergétiques et azotés de la ration et du taux de cellulose [7,16,22,49]. L'étude de la digestion et de l'absorption spécifique d'une protéine donnée n'est donc pas aisée en raison de cette contribution d'azote endogène difficile à estimer [2,20,23,44].…”

Molecular aspects of enzyme synthesis in the exocrine pancreas with emphasis on development and nutritional regulation

“…The possible mediators of nutritional adaptation are manifold: gut regulatory peptides released in response to the presence in the lumen of nutrients or hydrolysis products from dietary substrates and subsequent metabolites, or even absorbed circulating plasma metabolites. Pancreatic adaptation to dietary proteins, carbohydrates and fat has been widely investigated in various species (for recent reviews, see Corring et al 1989;Brannon, 1990). Although the molecular aspects of the pancreatic response to nutritional substrates are currently being investigated in both rats and pigs, only the most recent findings obtained with rats will now be discussed.…”
