Target of replication: *A priori* experimental protocols, materials, and confirmatory analysis plans were peer reviewed, [pre-registered][1], and published by [*eLife*][2]. This component includes all data, analysis scripts, and methods for the replication of the experiment reported in Figure 3D of [Dawson et al., 2011][3]. This experiment evaluates the effect of I-BET151 on _BCL2_ expression. [Figures component][4] contains a visualization of replication results. These figures are the same as can be found in the Replication Study and include Figure 2 displaying _BCL2_ expression following I-BET151 treatment. These scripts will call data directly from the OSF. [Statistical Analyses component][5] contains R scripts that were used for the analysis. These scripts will call data directly from the OSF. [Data component][6] contains data generated from the experimental work and files used in the analysis and generation of figures, which are in .csv format. [Methods component][7] contains methodology details for this replication attempt which were described in the [Registered Report][8]. [Cell line quality control data][9] includes results confirming the cells lines was free from mycoplasma contamination as well as STR DNA profiling of the cell lines used.
