The series of molecular signals initiated by the binding of a vascular endothelial growth factor (VEGF) to its receptor on the surface of a cell, which activates or increases the frequency, rate or extent of endothelial cell chemotaxis.

The series of molecular signals initiated by vascular endothelial growth factor (VEGF) binding to its receptor on the surface of a cell, which activates or increases the frequency, rate or extent of the orderly movement of a cell from one site to another.

Any process that stops, prevents, or reduces the frequency, rate or extent of signal transduction mediated by the phosphatidylinositol 3-kinase cascade.

Any process that activates or increases the frequency, rate or extent of the regulated release of serotonin.

Any process that activates or increases the frequency, rate or extent of secretion by cell.

Any process that modulates the frequency, rate or extent of the regulated release of serotonin.

The series of molecular signals beginning with a consequence of a G protein-coupled receptor promoting the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex, where the G protein-coupled receptor is not bound to an agonist.

A series of reactions within the signal-receiving cell, mediated by the intracellular phosphatidylinositol 3-kinase (PI3K). Many cell surface receptor linked signaling pathways signal through PI3K to regulate numerous cellular functions.

Combining with the sphingolipid sphingosine-1-phosphate (S1P), and transmitting the signal across the membrane by activating an associated G-protein.

Combining with a bioactive lipid and transmitting the signal across the membrane by activating an associated G-protein; promotes the exchange of GDP for GTP on the alpha subunit of a heterotrimeric G-protein complex. A bioactive lipid is a lipid for which changes in lipid levels result in functional consequences in a variety of cellular processes.

Any process that modulates the frequency, rate or extent of secretion by cell.

Any process that stops, prevents, or reduces the frequency, rate or extent of the regulated release of serotonin.

Any process that stops, prevents or reduces the frequency, rate or extent of secretion by cell.

The series of molecular signals initiated by a Wnt protein binding to a frizzled family receptor on the surface of a target cell, where the signal is passed on via the MAPKKK cascade.

The series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell, followed by propagation of the signal via effectors other than beta-catenin.

Any process that modulates the frequency, rate or extent of the regulated release of epinephrine.

Any process that modulates the frequency, rate or extent of the regulated release of catecholamines.

The series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell, where the signal is passed on via the JNK cascade.

The signaling process in which G protein-coupled receptor signaling is brought to an end. For example, through the action of GTPase-activating proteins (GAPs) that act to accelerate hydrolysis of GTP to GDP on G-alpha proteins, thereby terminating the transduced signal.

The signaling process in which signal transduction is brought to an end rather than being reversibly modulated.
