Abstract
Acute myeloid leukemia (AML) is an aggressive blood cancer with poor clinical outcomes. Emerging data suggest that mitochondrial oxidative phosphorylation (mtOXPHOS) plays a significant role in AML tumorigenesis, progression, and resistance to chemotherapies. However, how the mtOXPHOS is regulated in AML cells is not well understood. In this study, we investigated the oncogenic functions of ERR alpha in AML by combining in silico, in vitro, and in vivo analyses and showed ERR alpha is a key regulator of mtOXPHOS in AML cells. The increased ERR alpha level was associated with worse clinical outcomes of AML patients. Single cell RNA-Seq analysis of human primary AML cells indicated that ERR alpha-expressing cancer cells had significantly higher mtOXPHOS enrichment scores. Blockade of ERR alpha by pharmacologic inhibitor (XCT-790) or gene silencing suppressed mtOXPHOS and increased anti-leukemic effects in vitro and in xenograft mouse models.
