Mixtures of XEs, commonly found in contaminated environments, disrupt the signaling actions of physiological estrogens even more severely than do single XEs.
These signaling actions have been reduced to a simple activator-inhibitor feedback loop in computational modeling studies [ 22– 22].
Proinflammatory lipid mediators such as the eicosanoids compete against the signaling actions of newly discovered modified fatty acids that act to resolve inflammation.
The hypothalamus must have upward signaling actions to change learning and behavior, and indeed effects of leptin are seen at such levels (30).
Surprisingly our data suggest a novel model for how FAK regulates cellular signal transduction with important implications for understanding the role of FAK in multiple cell types and how distinct therapeutic interventions may target distinct FAK signaling actions.
Signaling actions of S1P can be executed within the intracellular space, as well as the extracellular space when it acts as a ligand of five G-protein coupled receptors (S1P1 S1P5) [ 34, 35].
36 The nucleocytoplasmic shuttling of IPMK and the identification of the nuclear receptor steroidogenic factor 1 as a new IPMK target also indicate the complexity of IPMK signaling actions.
A drastic move might also spark panic in financial markets, while not cutting at all would deal a serious blow to the Bank's credibility after it signalled action.
In movie posters and popular culture, we've allowed guns to signal action and thrills simply because we've settled for the bang over the big writing.
