Inactivation of NQO1 results in a temporal increase in acetyl α-tubulin levels in 3T3-L1 fibroblasts. (A) Acetyl α-tubulin levels were measured in 3T3-L1 fibroblasts after treatment with MI2321 (1 μM) for the indicated times. (B) NQO1 catalytic activity was measured in 3T3-L1 lysates obtained from fibroblasts treated with DMSO or MI2321 (1 μM) for the indicated times.
