Age-related human hematopoietic stem cell (HSC) exhaustion and myeloid-lineage skewing promote oncogenic transformation of hematopoietic progenitor cells into therapy-resistant leukemia stem cells (LSC) in secondary acute myeloid leukemia (sAML). While acquisition of clonal DNA mutations have been linked to increased rates of sAML for individuals over 60, the contribution of RNA processing alterations to human hematopoietic stem and progenitor aging and LSC generation remains unclear. Comprehensive RNA-sequencing and splice isoform-specific PCR uncovered characteristic RNA splice isoform expression patterns that distinguished normal young and aged HSPCs, compared with malignant MDS and AML progenitors. In splicing reporter assays and in pre-clinical patient-derived AML models, treatment with a pharmacologic splicing modulator, 17S-FD-895, reversed pro-survival splice isoform switching and significantly impaired LSC maintenance. By comparing splice isoform biomarkers of normal HSPC aging with those of LSC generation, splicing modulation may be employed safely and effectively to prevent relapse – the leading cause of leukemia-related mortality.
