Uveal melanoma (UM) is the most common intraocular malignancy in adults and frequently metastasizes. Somatic mutations and chromatin aberrations have been implicated in the pathogenesis of this deadly disease. Despite rapid progress in elucidating the genetic landscape of UM, the epigenetic architecture underlying UM pathogenesis remains incompletely understood. Here, we describe a super-enhancer-mediated epigenetic pipeline through genome-scale histone acetylation and transcriptional profiling. We first characterized the active landscape of super-enhancer profiles in UM via chromatin immunoprecipitation sequencing (ChIP-seq). We identified master transcription factors specifically driven by UM-specific super-enhancers, and our pipeline identified transcription factor AP-2 alpha (TFAP2A), which is highly associated with metabolism and oncogenesis, as the top essential regulator in UM. TFAP2A occupied predicted super-enhancers associated with the oncogene Solute Carrier Family 7 member 8 (SLC7A8) in UM, thereby elucidating a mechanism for regulating oncogene expression. Collectively, our data illustrate the potential for epigenetic targeting of super-enhancer-mediated oncogene dependencies in UM, highlighting an epigenetic vulnerability that can be exploited for precision therapy.
