These results indicate that local membrane deformations can transiently activate a Ca2+ permeability pathway leading to increased [Ca2+]i, secondary activation of Ca2+-sensitive K+ channels (Gardos channel, IK1, KCa3.1), and hyperpolarization-induced anion currents.
Metabolic alkalosis occurs in conditions associated with excess aldosterone activity, either autonomous secretion of aldosterone (primary aldosteronism) or secondary activation of the RAA system owing to renin-producing tumors, renal artery stenosis, and intravascular volume contraction of any etiology [ 30, 32, 33, 52].
7– 9 Our previous work demonstrated that the branched chain amino acid L-leucine activates SIRT1 10– 13 by lowering its activation energy for NAD+, 10 with secondary activation of AMPK.
Here, our findings revealed that nilotinib can inhibit the proliferation of 32D cells harboring secondary activation loop mutations more effectively than imatinib, and that may underlie the clinical activity of nilotinib in imatinib- and sunitinib-resistant GISTs.
It is possible that cluster headache is partially caused by disturbances in the hypothalamus including secondary activation of pain-sensitive nerves [33].
It is possible that FAA causes secondary activation of these regions due to the increased sensory input associated with high levels of locomotor activity.
Simplification of cell shape seems to be a later event which could fit with a secondary activation of actin/cell architecture pathways.
We demonstrate that endothelial sensing of dsDNA induces robust expression and secretion of TNFα, which mediates sustained secondary activation of the endothelium.
In contrast, at 12 hours, VCAM1 expression in the presence of TNFα neutralizing antibody was curtailed to the level in unstimulated cells, suggesting that dsDNA-induced TNFα is required for sustained secondary activation of the vascular endothelium.
They are conserved between mice and humans and exert various immunoregulatory functions through their rapid secretion of a variety of cytokines and secondary activation of dendritic cells, B cells and NK cells.
This response was dependent on the stress kinases JNK and p38 MAPK, required the activation of proinflammatory transcription factors NFκB and IRF3, and triggered the robust secretion of TNFα for sustained secondary activation of the endothelium.
