Western blotting of vimentin and Gap43 expression in GLUs and AGS-IVs.
(A) Modulation of vimentin and Gap43 by AGS-IV on glutamate-induced PC12 cell injury. Data shown are the results of three different experiments and are represented as the relative densities of vimentin (B) and Gap43 (C) protein bands normalized to β-actin. Results are presented as means ± SEM of three assays. ** Significant difference compared with GLUs by Student’s t-test (P < 0.01).
