Induction of γ gene promoter by amide analogues of trichostatin A. Four compounds were tested: M344 (▪), M360 (▤), MD85 (•), and M355 (). Each data point is based on triplicate determinations done in 3 separate experiments. For M344 and M360, concentrations greater than those presented in the figure were severely toxic to the cells. Vertical bars indicate SEM.
