Figure Lengend Snippet: Inhibition of HDAC1 activity in HT29 cells after 24 h of incubation with (a) polyphenols in the presence of catalase (100 U/mL) or (b) methyleugenol and methyleugenol metabolites. HDAC activity was determined by the metabolic rate of a specific HDAC1 substrate. Recombinant HDAC1 was included as positive control (PC) and trichostatin A (TA) as a specific HDAC inhibitor. The data presented are mean ± SD of at least three independent experiments, each performed in a duplicate. The significances indicated were calculated in relation to the solvent control DMSO 0.5% v/v (Student's t -test: * P ≤ 0.05; ** P ≤ 0.01).
Article Snippet: The HDAC reaction was initiated by adding 10 μ L of the diluted HDAC substrate (BOC- N ε -acetyl-L-lysine-7-amino-4-methylcoumarin) to each well.
