Abstract
Background: information In vivo oxygen levels in tissues range from 1% to 15%, while mechanistic cell culture studies employ an atmospheric oxygen level of 21% to grow cells. These oxygen concentrations are therefore not representative for conditions where the cell response is dependent on oxygen partial pressure. In pathological situation, such as (colon) cancer or chronic inflammation, tissue oxygenation is severely affected, and even under physiological conditions a steep oxygen gradient is present in the large intestine, where epithelial cells co-exist with microbial species, resulting in almost anoxia at the midpoint of the lumen. In these situations, a better characterisation of the essential cellular behaviour under hypoxia or anoxia is required. Results: We have characterised the cellular response of commonly used cell cultures for the study of intestinal epithelial processes and colon cancer development (Caco-2, HT-29, SW480, HCT 116 and LoVo) under conventional normoxic conditions (21% O-2) and in an anoxic (<0.1% O-2) environment generated in an anaerobic chamber. In general, anoxic conditions led to lower levels of oxidative stress, a reduction in reduced glutathione/oxidised glutathione (GSH/GSSG) ratio, the shift of the redox status to oxidised glutathione levels, reduced cell proliferation, decreased barrier function and higher glycolysis rates at the expense of oxidative respiration. Conclusions: Continuous exposure to anoxic conditions, such as occurring at the host-microbe interface in the intestine, may create an adaptive metabolic cellular response of the cells. Significance Considering adequate oxygen levels is essential for creating more physiologically relevant models for the study of host-microbe interactions and colon cancer development.
