<p>(A) HIFα mRNA levels were determined by real-time RT-PCR. Relative fold induction for HIFα mRNA (means ±SD) in I/R and RES group rat livers is presented relative to the expression in Sham operation group rat livers (*<i>P</i><0.05 compared with I/R group). (B) Western blot analysis for HIFα protein expression in the indicated groups. β-actin was used as a loading control.</p
