Analyses of soluble tubulin in different brain regions. Soluble fractions of RIPA extracts prepared from different brain regions of PDGF-α-Syn transgenic mice and wild type controls were analyzed for α-tubulin by Western blots as described in Methods. All values are expressed as percent change relative to changes observed in WT control animals. Results are from 3-4 animals per group; [*, p < 0.05] and [**, p < 0.01] compared to corresponding protein levels in WT animals. All blots are representative of samples.
