Data indicate that splicing factor 3b (zeige SF3B14 Antikörper), subunit 1 (sf3b1) mutation causes aberrant splicing of sf3b1 resulting in functional and predicted non-functional transcripts and a 90% reduction in full-length Sf3b1 protein.
these results indicate that the SF3B1K700E mutation induces MDS (zeige MECOM Antikörper) features in vivo and may be potentially targeted with spliceosome modulators to treat hematologic malignancies.
Our findings demonstrate that, despite significant differences in affected transcripts, there is overlap in the phenotypes associated with SF3B1-K700E between human and mouse.
Sf3b1(K700E) mice develop macrocytic anemia due to a term (zeige TCN2 Antikörper)inal erythroid maturation defect, erythroid dysplasia, and long-term hematopoietic stem cell (LT-HSC) expansion.
myocardial hypoxia actuates fructose metabolism in human and mouse models of pathological cardiac hypertrophy through hypoxia-inducible factor 1alpha (HIF1alpha (zeige HIF1A Antikörper)) activation of SF3B1 and SF3B1-mediated splice switching of KHK (zeige KHK Antikörper)-A to KHK (zeige KHK Antikörper)-C
Sf3b1 isrequired for the blastocyst formation.
SF3B1 plays an important role in the regulation of hematopoietic stem cells, whereas SF3B1 haploinsufficiency itself is not associated with the myelodysplastic syndrome phenotype with ring sideroblasts.
The level of Sf3b1 expression is critical for the proliferative capacity of hematopoietic stem cells. Depletion of Sf3b1 impairs proliferative capacity of hematopoietic stem cells but is not sufficient to induce myelodysplasia.
SF3B1 haploinsufficiency leads to formation of ring sideroblasts in myelodysplastic syndromes.
the active spliceosome, containing SAP155 phosphorylated by DYRKIA, performs pre-mRNA splicing in spermatogonia during testicular development
active spliceosome, containing phosphorylated SAP155, performs pre-mRNA splicing on chromatin concomitant with transcription during testicular development.
These findings provide evidence of a multipotent lymphomyeloid Hematopoietic stem cell origin of SF3B1 (zeige SF3B2 Antikörper) mutations in myelodysplastic syndrome with ring sideroblasts patients.
Mutation in SF3B1 (zeige SF3B2 Antikörper) gene is associated with Uveal Melanoma.
Mutation in SF3B1 (zeige SF3B2 Antikörper) is associated with myelodysplastic syndrome and chronic lymphocytic leukemia.
different HSH155 alleles elicit disparate effects on splicing: some increase the fidelity of BS selection while others decrease fidelity. Our data support a model wherein conformational changes in SF3b1 (zeige SF3B2 Antikörper) promote U2 association with the BS independently of the action of the DEAD-box ATPase (zeige DNAH8 Antikörper) Prp5 (zeige DDX46 Antikörper). We propose that SF3b1 (zeige SF3B2 Antikörper) functions to stabilize weak U2/BS duplexes to drive spliceosome assembly and splicing
mutations of SF3B1 (zeige SF3B2 Antikörper) may block erythropoiesis via dysregulation of alternative RNA splicing of transcription factor TAL1 (zeige TAL1 Antikörper)
Inhibition of SF3B1 (zeige SF3B2 Antikörper) with moderate levels of Pladienolide B, a previously established small molecule inhibitor of SF3B1 (zeige SF3B2 Antikörper), affects the transcriptional activation of HSF1 (zeige HSF1 Antikörper), the transcription factor that mediates the heat shock response.
Our findings demonstrate that, despite significant differences in affected transcripts, there is overlap in the phenotypes associated with SF3B1 (zeige SF3B2 Antikörper)-K700E between human and mouse.
Sf3b1 (zeige SF3B2 Antikörper)(K700E). Sf3b1 (zeige SF3B2 Antikörper)(K700E) mice develop macrocytic anemia (zeige TCN2 Antikörper) due to a terminal erythroid maturation defect, erythroid dysplasia, and long-term hematopoietic stem cell (LT-HSC (zeige FUT1 Antikörper)) expansion.
The blood sample from a patient with lung cancer with a known SF3B1 (zeige SF3B2 Antikörper) V701F mutation was also analyzed and this mutation was successfully identified in ptDNA. However, 1 of the patients with a K700E mutation was found to have a mutational burden of 98%.
data support a model in which cycloheximide -induced downregulation of the iron exporter ABCB7 (zeige ABCB7 Antikörper) mRNA transcript resulting from aberrant splicing caused by mutant SF3B1 (zeige SF3B2 Antikörper) underlies the increased mitochondrial iron accumulation found in MDS (zeige PAFAH1B1 Antikörper) patients with ring sideroblasts
This gene encodes subunit 1 of the splicing factor 3b protein complex. Splicing factor 3b, together with splicing factor 3a and a 12S RNA unit, forms the U2 small nuclear ribonucleoproteins complex (U2 snRNP). The splicing factor 3b/3a complex binds pre-mRNA upstream of the intron's branch site in a sequence independent manner and may anchor the U2 snRNP to the pre-mRNA. Splicing factor 3b is also a component of the minor U12-type spliceosome. The carboxy-terminal two-thirds of subunit 1 have 22 non-identical, tandem HEAT repeats that form rod-like, helical structures. Alternative splicing results in multiple transcript variants encoding different isoforms.
