Schematic representations of effects of hypoxia and aqueous extract of Cordyceps sinensis in A549 cells. Putative corelation among various transcription factors and mechanism of tolerance to hypoxia, upregulation/downregulation after hypoxia (solid arrow), and upregulation/downregulation after Cordyceps sinensis treatment (dotted arrow).
