HDAC activity is required for the GBM migration velocity. U87-MG cells were treated for 72 hours with TSA or SAHA and were monitored by time-lapse video microscopy or submitted to the transwell assay. Treatment with TSA led to a significant decrease in the rate of cell migration that was corroborated by the transwell assay. It is possible to observe a larger number of cells retained in the transwell matrix in the TSA group than in the control group. The same effect was observed when the cells were treated with SAHA, but this effect was enhanced when compared to TSA. . ; .
