Phosphoinositide-specific phospholipase C and mitogenic signaling.
The importance of PLC activation in cell proliferation is evident from the fact that the hydrolysis of PtdIns(4,5)P2 is one of the early events that follow the interaction of many growth factors and mitogens with their respective receptors. However, the importance of PLC activation is not restricted to proliferation; it is one of the most common transmembrane signaling events elicited by recept...
متن کاملCalcium by a Phospholipase C-Dependent Mechanism
Calcium signaling in fura-2 acetoxymethyl ester-loaded enteric glia was investigated in response to neuroligands; responses to AlP were studied in detail. Carbachol (1 mM), glutamate (100 jiM), norepinephrine (10 jiM), and substance P (1 pM) did not increase the intracellular calcium concentration ([Ca24 ],) in cultured enteric glia. An increasing percentage of glia responded to serotonin (4%; ...
متن کاملCalcium signalling: Sphingosine kinase versus phospholipase C?
A recent study shows that sphingosine kinase and its lipid product have an essential signalling function; they act in the mobilization of calcium ions in antigen-stimulated mast cells. This finding may have relevance to signalling in other cells of the immune system.
متن کاملFilamin and Phospholipase C-ε are required for calcium signaling in the Caenorhabditis elegans Spermatheca
The Caenorhabditis elegans spermatheca is a myoepithelial tube that stores sperm and undergoes cycles of stretching and constriction as oocytes enter, are fertilized, and exit into the uterus. FLN-1/filamin, a stretch-sensitive structural and signaling scaffold, and PLC-1/phospholipase C-ε, an enzyme that generates the second messenger IP3, are required for embryos to exit normally after fertil...
متن کاملListeria monocytogenes phospholipase C-dependent calcium signaling modulates bacterial entry into J774 macrophage-like cells.
Listeria monocytogenes secretes several proteins that have been shown to contribute to virulence. Among these is listeriolysin O (LLO), a pore-forming hemolysin that is absolutely required for virulence. Two other virulence factors are phospholipases: a phosphatidylinositol-specific phospholipase C (PI-PLC [plcA]) and a broad-range PLC (plcB). Although mutations in plcA or plcB resulted in smal...
