SOX2 drives esophageal squamous carcinoma by reprogramming lipid metabolism and histone acetylation landscape.

ABSTRACT: SOX2 is a potent oncodriver for various squamous cancers, but the underlying mechanism is largely unknown. Here we uncover a role of SOX2 in promoting global histone acetylation in esophageal squamous cancer cells (ESCCs). Mechanistic studies reveal that SOX2 promotes global histone acetylation in an AKT-independent manner, and does so by promoting histone acetylation at both SOX2 binding and non-SOX2 binding sites, and accounts for the formation of about half of the super-enhancers. Combined metabolic and transcriptional analyses reveal two mechanisms by which SOX2 enhances global histone acetylation: promoting the expression of multiple histone acetyltransferases and reducing acetyl-CoA consuming fatty acid synthesis in part by repressing the expression of ACSL5. Finally, SOX2 expression
