H]ADP/ATP. Furthermore, following a period of hypoxia, HUVEC underwent concurrent changes in intracellular signaling manifested in the depletion of putative ATP stores and targeted up-regulation of phospho-p53, p70S6K/mTOR and other tyrosine kinases. The revealed complex implication of both extrinsic and intrinsic mechanisms into a tuned hypoxia-induced control of purine homeostasis and signaling may open up further research for the development of pharmacological treatments to improve endothelial cell function under disease conditions associated with a loss of cellular ATP during oxygen deprivation.
