متن کاملEndothelial Cell HIF-1α and HIF-2α Differentially Regulate Metastatic Success
The hypoxia inducible transcription factors (HIFs) control many mediators of vascular response, including both angiogenic factors and small molecules such as nitric oxide (NO). In studying how endothelial HIF response itself affects metastasis, we found that loss of HIF-1α in endothelial cells reduces NO synthesis, retards tumor cell migration through endothelial layers, and restricts tumor cel...
متن کاملNOX Family NADPH Oxidases
Proton channels allow cells to extrude excess acid with a high efficiency and therefore are one of the important homeostatic mechanisms that maintain the intracellular pH in a range compatible with life. Proton currents are highly expressed in phagocytes where they are thought to contribute to charge and pH compensation during NADPH oxidase activation. By analogy with the cytochrome C oxidase o...
متن کاملBeluga whale pVHL enhances HIF-2α activity via inducing HIF-2α proteasomal degradation under hypoxia
Aquatic mammals, such as cetaceans experience various depths, with accordingly diverse oxygenation, thus, cetaceans have developed adaptations for hypoxia, but mechanisms underlying this tolerance to low oxygen are unclear. Here we analyzed VHL and HIF-2α, in the hypoxia signaling pathway. Variations in VHL are greater than HIF-2α between cetaceans and terrestrial mammals, and beluga whale VHL ...

and Duox in the respiratory epithelium. The location of these ROS-generating enzymes in the barrier tissues has prompted the expectation of their participation in host defense against invading pathogens in these tissues. Indeed, recent studies have begun to support this expectation, demonstrating roles in bacterial killing, cytokine production, apoptosis, gene expression and signaling, includin...
