Quantitative 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 کاملEffect of glucose deprivation on rat glutamine synthetase in cultured astrocytes.
Glutamine synthetase was purified from the cerebral cortex of adult rats and characterized. Polyclonal rabbit antibodies were raised against the enzyme, purified and their specific anti-(glutamine synthetase) activity determined. A primary astroglial culture was prepared from newborn Sprague-Dawley rats. Astrocytes at different ages of development were incubated in the presence and absence of g...
متن کاملTroglitazone inhibits glutamine metabolism in rat mesangial cells.
Troglitazone is a peroxisome proliferator-activated receptor-gamma agonist that has been shown to halt mesangium expansion in experimental models of type 2 diabetes mellitus and to act directly on rat mesangial cells. Because glutamine serves as the precursor for cellular biosynthetic processes, we asked whether troglitazone would inhibit mesangial cell glutamine metabolism under these conditio...
متن کاملSynthetic lethality in KRas-driven cancer cells created by glutamine deprivation
Oncogenic KRas mutations are present in about 30% of all human cancers and in more than 90% of pancreatic cancers. KRas-driven cancers have been largely resistant to therapeutic intervention and KRas itself has been considered undruggable. However, two recent studies have uncovered what may be an Achilles’ heel for cancer cells harboring activating KRAS mutations [1, 2]. These studies exploit a...
متن کاملGlutamine deprivation plus BPTES alters etoposide- and cisplatin-induced apoptosis in triple negative breast cancer cells
Glutamine provides cancer cells with the energy required to synthesize macromolecules. Methods which block glutamine metabolism in treatment of breast cancer inhibit oncogenic transformation and tumor growth. We investigated whether inhibiting glutamine metabolism produces effects that are synergistic with those produced by drugs which damage DNA in triple-negative breast cancer cells. HCC1937 ...
