Defining direct targets of transcription factors and regulatory pathways is key to understanding their roles in physiology and disease. Here we combine SLAM-seq, a method for direct quantification of newly synthesized mRNAs, with pharmacological and chemical-genetic perturbation to define regulatory functions of two transcriptional hubs in cancer, BRD4 and MYC, and to interrogate direct responses to BET bromodomain inhibitors (BETi). We find that BRD4 acts as general co-activator of RNA polymerase II (Pol2)-dependent transcription, which is broadly repressed upon high-dose BETi treatment. At doses triggering selective effects in leukemia, BETi deregulate a small set of hypersensitive targets including MYC. In contrast to BRD4, MYC primarily acts as a selective transcriptional activator controlling metabolic processes such as ribosome biogenesis and de-novo purine synthesis. Our study establishes a simple and scalable strategy to identify direct transcriptional targets of any gene or pathway.
