Disruption of RNAPII transcription elongation links Oncogenic splicing factor mutations to replciation stress and targetable alterations in chromatin landscape [GRO-seq]

ABSTRACT: To investigate redistribution of RNAPII in response to the SF3B1 mutation and to study its effects on nascent gene expression, we peformed fastGRO-seq (variant of GRO-seq using 4-thio-UTP based nuclear run-on) in K562 cells (wild type and SF3B1K700E mutant) at 4 days after mutant allele expression We then performed metaplot-based and gene expression analysis using data obtained from fastGRO-seq

Physiologic expression of Sf3b1K700E causes impaired erythropoieses, aberrant splicing, and sensitivity to pharmacologic spliceosome modulation

Project description:Over 80% of patients with the refractory anemia with ring sideroblasts subtype of myelodysplastic syndrome (MDS) have mutations in Splicing Factor 3B, Subunit 1 (SF3B1). We generated a conditional knock-in mouse model of the most common SF3B1 mutation, Sf3b1K700E. Sf3b1K700E mice develop macrocytic anemia due to a terminal erythroid maturation defect, erythroid dysplasia, and long-term hematopoietic stem cell (LT-HSC) expansion. Sf3b1K700E myeloid progenitors and SF3B1-mutant MDS patient samples demonstrate aberrant 3' splice-site selection associated with increased nonsense-mediated decay. Tet2 loss cooperates with Sf3b1K700E to cause a more severe erythroid and LT-HSC phenotype. Furthermore, the spliceosome modulator, E7017, selectively kills Sf3b1K700E-expressing cells. Thus, Sf3b1K700E expression reflects the phenotype of the mutation in MDS and may be a therapeutic target in MDS.
