Hypoxia defenses

Interestingly, studies of hypobaric hypoxia defense adaptations in the human heart have shown that the above metabolic organization can be visualized noninvasively and in vivo using 31P MRS. To put this into perspective,...

MODEL OF HYPOXIA DEFENSE IN SYSTEMS TOLERANT TO HYPOXIA... 

From these studies, it is now possible to construct a generalized framework or working hypothesis for how hypoxia-tolerant cells respond to oxygen lack (figure 3.18). During the very early acute phases, a poorly understood hypoxia-sensing and signal transduction system orchestrates a series of molecular hypoxia defense processes, which include ... 

Acute high-altitude studies of both human and animal models indicate that hypoxia defenses are initiated by several oxygen sensing, signal transduction pathways. For convenience, these have been summarized as five general hypoxia response systems (figure 5.2(A)-(E) ...
