Hormonal control of renal and systemic glutamine metabolism.
Glutamine is the most abundant free amino acid in the human body. Recent studies indicate that it may be an important vehicle for interorgan nitrogen and carbon transport. However, relatively little is known about hormonal factors regulating its metabolism in humans. We review here our recent work on the effects of insulin, glucagon and epinephrine on plasma glutamine kinetics and its conversio...
متن کاملRegulation of Bone Metabolism
Bone is formed through the processes of endochondral and intramembranous ossification. In endochondral ossification primary mesenchymal cells differentiate to chondrocytes and then are progressively substituted by bone, while in intramembranous ossification mesenchymal stem cells (MSCs) differentiate directly into osteoblasts to form bone. The steps of osteogenic proliferation, differentiation,...
متن کاملRegulation of mitochondrial glutamine/glutamate metabolism by glutamate transport: studies
Welbourne, Tomas, and Itzhak Nissim. Regulation of mitochondrial glutamine/glutamate metabolism by glutamate transport: studies with 15N. Am J Physiol Cell Physiol 280: C1151–C1159, 2001.—We focused on the role of plasma membrane glutamate uptake in modulating the intracellular glutaminase (GA) and glutamate dehydrogenase (GDH) flux and in determining the fate of the intracellular glutamate in ...
متن کاملQuantitative aspects of glucose and glutamine metabolism by intestinal cells.
Gut fuel utilisation has several unique features. Arterial and luminal fuels provide nutrition for the enterocyte, the former being of more importance. This factor, and the heterogeneity of cell types within the gut makes it difficult to define its fuel utilisation. Metabolic control logic suggests that modulation of the maximal activity of any pathway resides in those enzymes that operate in v...
متن کاملEnd products of glucose and glutamine metabolism by L929 cells.
Products of glucose and glutamine metabolism by L929 cells were detected and quantitated by gas chromatography and mass spectrometry of the oxime-trimethylsilyl derivatives. This method allowed detection and identification of all major carboxylic and amino acids produced in the system. Although lactic acid was expected to be the major product, alanine, citric, glutamic, aspartic, and pyruvic ac...
