Figure 3: Inhibition of migration due to increased acetylation of microtubules can be rescued by counterbalancing with increased contractility.

(a) Relative migration velocity of HFFs stably expressing GFP (control) or different tubulins as indicated. Velocities were normalized to the control. A minimum of 50 time points were used per measurement from >30 cells (n>3). (b) Relative migration velocity of TSA-treated HFFs (5 μM TSA) expressing GFP (control), GFP-tagged phospho-mimetic MLC (rMLC-DD; activated) or GFP-tagged phospho-null MLC (rMLC-AA; negative). Velocities were normalized to the control. A minimum of 40 time points were used per measurement from >20 cells (n=3). (c) Relative migration velocity of HFFs expressing Flag-tagged HDAC6 treated with 20 μM ML-7. Each velocity was normalized to the control. A minimum of 30 time points were used per measurement from >45 cells (n=3). Data are mean±s.e.m.*P<0.05. Two-way analysis of variance (ANOVA) followed by Tukey post test was used for a, and Student’s t-test was used for b and c.
