Inositol phospholipid metabolism and myoblast fusion.
The fusion of chick embryonic myoblasts has been studied in tissue culture. Myoblasts are maintained at 0.1 microM-Ca2+ for 50 h. During this time they achieve fusion competence. Fusion is initiated by raising the medium Ca2+ concentration to 1.4 mM. A rapid breakdown of the polyphosphoinositides was detected within 3 min of Ca2+ addition. Rapid synthesis of phosphatidic acid was also detected ...
متن کاملInositol phospholipid metabolism in Arabidopsis. Characterized and putative isoforms of inositol phospholipid kinase and phosphoinositide-specific phospholipase C.
Phosphoinositides (PIs) constitute a minor fraction of total cellular lipids in all eukaryotic cells. They fulfill many important functions through interaction with a wide range of cellular proteins. Members of distinct inositol lipid kinase families catalyze the synthesis of these phospholipids from phosphatidylinositol. The hydrolysis of PIs involves phosphatases and isoforms of PI-specific p...

متن کاملRole of inositol phospholipid signaling in natural killer cell biology
Natural killer (NK) cells are important for host defense against malignancy and infection. At a cellular level NK cells are activated when signals from activating receptors exceed signaling from inhibitory receptors. At a molecular level NK cells undergo an education process to both prevent autoimmunity and acquire lytic capacity. Mouse models have shown important roles for inositol phospholipi...
متن کاملInositol phospholipid signaling and the biology of natural killer cells.
A family of phosphoinositide-3 kinase (PI3K) isoenzymes catalyzes the production of second messengers that recruit critical regulators of cell growth, survival, proliferation and motility. Conversely, 3'-(phosphatase and tensin homolog) and 5'-inositol polyphosphatases (SH2-containing inositol phosphatases 1/2, SHIP1/2) are recruited to sites of PI3K signaling at the plasma membrane to oppose o...
