The enigmatic presence of all gluconeogenic enzymes inSchistosoma mansoniadults

Autor: Aloysius G.M. Tielens, J.M. van den Heuvel, P. van der Meer, S.G. van den Bergh

Publikováno v: Parasitology. 102:267-276

SUMMARYThe activities of glucose-6-phosphatase (G6Pase), frucrose-1,6-bisphosphatase (FBPase), phosphoenolpyruvate carboxykinase (PEPCK) and pyruvate carboxylase (PC) were determined in homogenates of adultSchistosoma mansoniworms and compared with t

The transition from an aerobic to an anaerobic energy metabolism in transforming Schistosoma mansoni cercariae occurs exclusively in the head

Autor: Aloysius G.M. Tielens, Anja M.C. Horemans, S.G. van den Bergh

Publikováno v: Parasitology.

SUMMARYIt has been shown that in intact cercariae of Schistosoma mansoni in water, both head and tail had an identical, aerobic energy metabolism. As long as the environment was water, glucose was mainly degraded to carbon dioxide by both head and ta

Substrate cycling between glucose 6-phosphate and glycogen occurs in Schistosoma mansoni

Autor: J.M. van den Heuvel, Aloysius G.M. Tielens, S.G. van den Bergh

Publikováno v: Molecular and biochemical parasitology. 39(1)

The regulation of glycogen metabolism in Schistosoma mansoni was studied in vitro with special emphasis on the possible occurrence of substrate ('futile') cycling. The partition of label between carbon atoms 1 and 6 of the glucose units in glycogen w

Phorbol esters, but not epidermal growth factor or insulin, rapidly decrease soluble protein kinase C activity in rat hepatocytes

Autor: C.G.M. de Haas, S.G. van den Bergh, W.J. Vaartjes

Publikováno v: Biochemical and Biophysical Research Communications. 138:1328-1333

Summary Exposure of freshly isolated rat hepatocytes to tumor-promoting phorbol esters like phorbol 12-myristate 13-acetate resulted in a time- and concentration-dependent translocation of protein kinase C from the soluble to the particulate fraction

Regulation of fat mobilization in adipose tissue of dairy cows in the period around parturition

Autor: Stef H.M. Metz, S.G. van den Bergh

Publikováno v: Netherlands Journal of Agricultural Science 25 (1977)

Samples of subcutaneous adipose tissue were taken from Dutch Black Pied and Meuse-Rhine-Yssel cows at regular intervals from about a month before until a month after parturition. Tissue was incubated in Krebs-Ringer bicarbonate buffer with 5% bovine

The energy metabolism of Fasciola hepatica during its development in the final host

Autor: S.G. van den Bergh, Aloysius G.M. Tielens, J.M. van den Heuvel

Publikováno v: Molecular and Biochemical Parasitology, 13(3), 301. Elsevier

Mature liver flukes, Fasciola hepatica, of different ages were isolated from the bile ducts of experimentally infected rats. Their energy metabolism was studied during aerobic incubation with [6-14C]glucose. The results showed that the aerobic potent

Persistent changes in the initial rate of pyruvate transport by isolated rat liver mitochondria after preincubation with adenine nucleotides and calcium ions

Autor: S.G. van den Bergh, J.N. den Breejen, Math J.H. Geelen, W.J. Vaartjes

Publikováno v: Biochimica et Biophysica Acta (BBA) - Bioenergetics. 592:28-37

1. Preincubation of isolated rat-liver mitochondria in the presence of adenine nucleotides or Ca2+ results in definite and persistent changes in the initial rate of pyruvate transport. 2. These changes in the rate of pyruvate transport are accompanie
