Menin-MLL1 complex cooperates with NF-Y to promote hepatocellular carcinoma survival.

ABSTRACT: Chromatin regulators are frequently mutated or aberrantly expressed in hepatocellular carcinoma (HCC), suggesting that the dysregulation of chromatin is a key feature driving liver cancer. In this study, using an epigenome-focused CRISPR screen in two-dimensional (2D) and three-dimensional (3D) conditions, we find the subunits of the menin-MLL1 complex to be among the strongest candidates for HCC survival. Inhibition of the menin-MLL1 interaction leads to global changes in occupancy of the complex with concomitant decreases in H3 lysine 4 trimethylation (H3K4me3), accessibility, and gene expression. Newly opened chromatin sites not bound by menin-MLL1 are associated with the recruitment of the pioneer transcription factor complex NF-Y yet remain embedded in silent chromatin domains, sugges
