Tubulin PTM modification results in increased axonal β1 integrin. A, B, Low-dose taxol treatment increased β1 integrin level in the axons with group difference of 3.149 ± 0.697 arbitrary units (p < 0.001). C, D, TSA-induced increased acetylation did not increase β1 integrin level in the axons. E, F, Taxol treatment increased α9-GFP vesicle anterograde movement. **p < 0.01; *p < 0.05. Scale bars in A–C, 25 μm.
