FIG. 3.

Inhibition of histone deacetylase 6 (HDAC6) activity increases tubulin acetylation without affecting STAT3 localization. Jurkat cells were treated with DMSO or HDAC6-selective inhibitor tubacin for 4 h, and then cells were stained with anti-STAT3 and anti-acetylated tubulin antibodies and DAPI.
