Web31 aug. 2012 · Hypoxia, defined as areas with oxygen tension values of 10 mmHg or lower, is a common feature of solid tumors that occurs across a wide variety of malignancies ( 1, 2 ). Once cells encounter hypoxia, a large number of genes that stimulate adaptation to oxygen deprivation are induced. WebThe use of a ketone body (beta-hydroxybutyrate) indicated that an energy deficiency was responsible for the hypoxia-induced increase in [Ca2+]i. We actually observed a 43% decrease in ATP concentration after 2 h hypoxia. This decrease was already significant after 30 min which thus precedes the changes in [Ca2+]i. isaiah explained
