It is the most common cause of death in cats over the age of 5 years (O'Neill et al., 2015).The kidney is the organ that senses the oxygen carrying capacity of the blood and communicates with the bone marrow via the hormone … WebOct 23, 2024 · At the core of this ancient response are proteins called hypoxia-inducible factors (HIFs), which instruct the cell to minimize oxygen consumption and maximize their access to oxygen. In this way, HIFs can be thought of as valiant heroes attempting to protect and resuscitate cells in the immediate response to low oxygen.
