a HDAC6 is expressed in six lymphoma cell lines. Whole-cell lysates were subjected to western blotting using the indicated Abs. Tubulin was used to normalize protein loading. b Ricolinostat alone induced dose and time dependent manner growth inhibition in NHL cell lines that were treated with a serial dosage of ricolinostat (1–10 µM) for 24–72 h. Data shown are representative of at least three independent experiments and represent the mean ± SD. c Antiproliferative activity of bendamustine (25–300 µM) for 24 h. Values represent three independent experiments and represent the mean ± SD
