Glutamate, glutamine, aspartate, asparagine, glucose and ketone-body metabolism in chick intestinal brush-border cells.
1. Suspensions of isolated chick jejunal columnar absorptive (brush-border) cells respired on endogenous substrates at a rate 40% higher than that shown by rat brush-border cells. 2. Added d-glucose (5 or 10mm), l-glutamine (2.5mm) and l-glutamate (2.5mm) were the only individual substrates which stimulated respiration by chick cells; l-aspartate (2.5 or 6.7mm), glutamate (6.7mm), glutamine (6....
متن کاملGlutamate and asparagine cataplerosis underlie glutamine addiction in melanoma
Glutamine dependence is a prominent feature of cancer metabolism, and here we show that melanoma cells, irrespective of their oncogenic background, depend on glutamine for growth. A quantitative audit of how carbon from glutamine is used showed that TCA-cycle-derived glutamate is, in most melanoma cells, the major glutamine-derived cataplerotic output and product of glutaminolysis. In the absen...
متن کاملGlutamate and Glutamine in Metabolism Glutamine and Glutamate Exchange between the Fetal Liver and the Placenta
The transport and metabolism of glutamine (GLN) and glutamate (GLU) during fetal development exhibit unique characteristics that clearly emphasize the importance of the interaction between the placenta and the fetal liver. GLN is delivered into the fetal circulation at a rate that is the highest of all the amino acids. In contrast, ;90% of fetal plasma GLU is extracted by the placenta. Converse...
متن کاملGlutamate transport asymmetry in renal glutamine metabolism.
d-Glutamate (Glu) was previously shown to block l-Glu uptake and accelerate glutaminase flux in cultured kidney cells [Welbourne, T. C., and D. Chevalier. Am. J. Physiol. 272 ( Endocrinol. Metab. 35): E367-E370, 1997]. To test whether d-Glu would be taken up by the intact functioning kidney and effect the same response in vivo, male Sprague-Dawley rats were infused withd-Glu (2.6 μmol/min), and...
متن کاملGlutamine and glucose metabolism during thymocyte proliferation. Pathways of glutamine and glutamate metabolism.
Energy metabolism in proliferating cultured rat thymocytes was compared with that of freshly prepared non-proliferating resting cells. Cultured rat thymocytes enter a proliferative cycle after stimulation by concanavalin A and Lymphocult T (interleukin-2), with maximal rates of DNA synthesis at 60 h. Compared with incubated resting thymocytes, glucose metabolism by incubated proliferating thymo...
