“…In the adult rat in vivo, glucagon counter acts the liver protein synthesis due to the important AA flux from gut [37], In the suck ing rat, glucagon could play the same role during digestion.…”

“…We have shown elsewhere (Lardeux, Bourdel and Girard-Globa, 1978) that ingestion of the casein meal is followed by a stimulation of liver protein synthesis. On the grounds that Ala-AT is always depressed under conditions of stimulated liver growth, Rosen et al (1963), Harding, Rosen and Nichol (1966a, b) postulated an inverse relationship between transamination and protein synthesis ; our finding that Ser-DH is considerably depressed should add weight to this argument.…”

“…and Aufrère, lack of effect was partly due to the induction of enzymes of amino acid catabolism in the liver (Harper, 1965 ;Szepesi and Freedland, 1968 ;Pestana, 1969 ;Mauron, Mottu and Spohr, 1973 ;Yanagi, Campbell and Potter, 1975) and to an increase in the capacity for ureogenesis (Schimke, 1962). On the contrary, even after a 4-week adaptation period, the ingestion of a protein meal fed separately can induce an important increase in liver protein synthesis (over 3-fold within 1 h) (Lardeux, Bourdel and Girard-Globa, 1978 (De Rosa and Swick, 1975). Tyrosine aminotransferase was thought to be of interest since, like ornithine decarboxylase, it has a short half-life and is thus sensitive to variations in protein synthetic activity.…”

“…Des travaux récents de l'équipe de Khairallah (1978) ont montré in vivo après un repas complet, une diminution très rapide de la vitesse de dégradation des protéines du foie associée à une diminution du nombre et de la taille des lysosomes et surtout des vacuoles autophagiques. Dans notre laboratoire, nous avons observé des modifications rapides et importantes du métabolisme protéique hépatique après la consommation des protéines sous forme d'un repas ponctuel au cours de la période diurne (Lardeux, Bourdel et Girard-Globa, 1978). Ces résultats nous ont amené à conclure, à l'existence d'une stimulation simultanée de la synthèse et de la dégradation des protéines, allant de pair avec une augmentation de la néoglucogenèse et de l'uréogenèse (Lardeux, Bourdel et Girard-Globa, 1978 ;Peret, Chanez et Bois, 1978), qui pourrait être liée à des altérations rapides de l'équilibre hormonai : élévation du glucagon porte (Jarousse et al, 1980) et de l'AMP cyclique du foie (données non publiées).…”
