Inositol lipid metabolism and signal transduction in clonal pituitary cells.
A number of clonal cell lines derived from a rat pituitary tumour, collectively termed GH cells, have retained a range of differentiated cell functions, including their ability to secrete the hormones prolactin and growth hormone in response to stimuli such as thyrotropin-releasing hormone (TRH). The mechanisms underlying this release process involve, at least in part, an increase in cytosolic ...
متن کاملGolgi Membrane Dynamics and Lipid Metabolism
The striking morphology of the Golgi complex has fascinated cell biologists since its discovery over 100 years ago. Yet, despite intense efforts to understand how membrane flow relates to Golgi form and function, this organelle continues to baffle cell biologists and biochemists alike. Fundamental questions regarding Golgi function, while hotly debated, remain unresolved. Historically, Golgi fu...
متن کاملEnzymes of myo-inositol and inositol lipid metabolism in rats with streptozotocin-induced diabetes.
Diabetes, with only mild ketosis, was induced in male rats by a single injection of streptozotocin. After 12 weeks the specific activities of enzymes concerned with the metabolism of inositol and of inositol lipids were measured in various tissues. Inositol 1-phosphate synthase (EC 5.5.1.4) was most active in testis and the activity was significantly less in diabetic rats than in controls on a ...
متن کاملInhibition of human erythrocyte inositol lipid metabolism by adriamycin.
Incubation of human erythrocytes with Adriamycin prevented their morphological transition from discocytes to echinocytes when they were either depleted of ATP or loaded with calcium. This effect was dependent upon drug concentration and cell density. Adriamycin (10(-5) M) prevented, by greater than 90%, the echinocytosis of 10(7) cells/ml (S. B. Chahwala and J. A. Hickman, Cancer Res., 45: 4986...
متن کاملInositol metabolism and cell growth in a Chinese hamster ovary cell myo-inositol auxotroph.
The intracellular concentrations of polyphosphoinositides and inositol phosphates were determined, and their role in growth factor-initiated cell division was investigated in a Chinese hamster ovary cell inositol auxotroph (CHO-K1-Ins). Metabolic labeling experiments during inositol starvation of CHO-K1-Ins cells showed that 1) the lipid-linked inositol component was maintained at the expense o...
