KLF6 expression was induced in injured sciatic nerves.

<p><i>A</i>. Time course of KLF6 expression as indicated by real-time PCR following rat sciatic nerve injury. The data are normalized to GAPDH expression and presented as fold-change relative to the normal control. *<i>p</i><0.05 vs. normal control (<i>t</i>-test). <i>B</i>. Western blots showed that KLF6 expression was upregulated in a time dependent manner at the site of sciatic nerve injury, while in the sham operation group KLF6 expression showed no obvious change. <i>C</i>. and <i>D</i>. Immunohistochemical detection of KLF6, S-100 and p75NTR expression in the injured nerve. Representative images are shown and the scale bar=50 μm.
