α-Tubulin and detyrosinated (deTyr) tubulin expression. α-Tubulin and detyrosinated tubulin were assessed following 3 days of treatment of C2C12 myotubes (A) with vehicle [Ctrl (DMSO), n = 6] or paclitaxel (Tax, 40 nM, n = 6) and in controls (n = 11) and breast cancer patients (n = 9) (B). Gel images are provided for both experiments. AU, arbitrary units. Values are means ± SE, with individual data points shown with each bar. *P < 0.05, **P < 0.01 vs. control.
