Web2 de jun. de 2009 · Endogenous HIF1A knockdown was confirmed by western blot (Supplementary Figure S4A). The 5-fold induction of promoter 1 in hypoxia was reduced to 1.3-fold in the presence of HIF1A siRNA (Supplementary Figure S4B). These results suggested that sites 1 and 2 are the physiologically relevant HIF-1-binding sites.
