Differential expression of cytokines and receptor expression during anoxic growth.


ABSTRACT: OBJECTIVE:Cell density in tumor cell three dimensional (3D) cultures affects secretome expression of components. A microenvironment characteristic shared by high-density 3D cell culture and in vivo tumor masses is poor oxygenation, with anoxia being a natural cell state in tumor centers. Until recently, the ability to study anoxia-adapted cell physiology was not possible. Using a newly-developed methodology, anoxic HeLa cell secretome expression was measured. RESULTS:Anoxic HeLa cell cytokine levels after 3 days' (hypoxia inducible factor, HIF1 positive) and 10 days' growth (HIF1 negative; anaerobic respiration) were significantly (p?
