MLN4924 fails to increase acetylated tubulin in tubacin-pretreated HAECs. (A) HAECs were pretreated with tubacin for 4 h before addition of MLN4924 (1 μM). After an 18 h incubation, cells were immunoblotted (IB) with antibodies to acetylated α-tubulin, HDAC6, and total α-tubulin. (B,C) Densitometric analysis of HDAC6 and acetylated α-tubulin levels presented in (A). ∗p < 0.05 vs. DMSO (control) group; n = 3.
