A sensible approach to making sense of oxygen sensing.

The article discusses the author's insights on the study "Gene expression analyses reveal metabolic specification in acute O2-sensing chemoreceptor cells" by I. Gao and colleagues. He outlines the results of the said study which attempted to identify signature features likely to play key roles in acute PO2 sensing. The author notes that the research has suggested potential markers that are likely to convey O2 sensitivity in chemoreceptor cells.
