Expression of RGMa, FAK (Tyr397) and Ras by western blot analysis. (A) Western blot analysis showed the decreased expression of RGMa from 3 days, which was maintained at 6 weeks in the PTZ group. (B) The expression of FAK (Tyr397) increased markedly from 1 week and reached a peak at 4 weeks, then declined at 6 weeks. (C) Western blot analysis revealed increased expression of Ras from 1 week, which reached a peak at 4 weeks in the PTZ group. RGMa, repulsive guidance molecule A; FAK, focal adhesion kinase; PTZ, pentylenetetrazole.
