HDAC6 does not affect the cell proliferation and cell cycle progression. (A) Raji cells were treated with DMSO, NaB, or tubacin for the indicated time, and cell viability was determined by CellTiter-Glo luminescent cell viability assay. (B) Cell cycle analysis of Raji cells treated with DMSO, NaB, or tubacin. (C) Experiments were performed as in panel B, and the percentage of cells in G1, S, and G2/M phases was calculated. *, P < 0.05 versus control; ns, not significant.
