Overexpression of PTB enhanced HIF-1alpha IRES activity, whereas RNA interference mediated downregula-tion of PTB protein expression inhibited HIF-1alpha IRES activity

Lowering PTB expression or HuR expression using RNA interference reduced HIF-1alpha translation and expression levels but not HIF-1alpha mRNA abundance
