Circular RNAs of the Nucleophosmin (NPM1) Gene in Acute Myeloid Leukemia

Abstract

In acute myeloid leukemia, there is growing evidence for splicing pattern deregulation, including differential expression of linear splice isoforms of the commonly mutated gene (). In this study, we detect circular RNAs of and quantify circRNA hsa_circ_0075001 in a cohort of wild-type and mutated acute myeloid leukemia (n=46). Hsa_circ_0075001 expression correlates positively with total expression, but is independent of the mutational status. High low hsa_circ_0075001 expression defines patient subgroups characterized by distinct gene expression patterns, such as lower expression of components of the Toll-like receptor signaling pathway in high hsa_circ_0075001 expression cases. Global evaluation of circRNA expression in sorted healthy hematopoietic controls (n=10) and acute myeloid leukemia (n=10) reveals circRNA transcripts for 47.9% of all highly expressed genes. While circRNA expression correlates globally with parental gene expression, we identify hematopoietic differentiation-associated as well as acute myeloid leukemia subgroup-specific circRNA signatures.
