Nuclear entry of β-catenin after treatment of HRECs with siRNA <i>Per2</i>.

<p><i>Per2</i> or control siRNA-treated HRECs were processed to separate nuclear and cytoplasmic fractions. Representative western blots showed nuclear translocation of β-catenin after treatment with <i>Per2</i> siRNA. Histone H3 and α-tubulin were used as loading controls for nuclear and cytoplasmic fractions, respectively n = 3.
