Myelodysplastic syndromes: Contemporary review and how we treat.
Rochester, United States. In Am J Hematol, Jan 2016
With the advent of next generation sequencing, recurrent somatic mutations in genes involved in epigenetic regulation (TET2, ASXL1, EZH2, DNMT3A, IDH1/2), RNA splicing (SF3B1, SRSF2, U2AF1, ZRSR2), DNA damage response (TP53), transcriptional regulation (RUNX1, BCOR, ETV6) and signal transduction (CBL, NRAS, JAK2) have been identified in MDS.
Do somatic mutations in de novo MDS predict for response to treatment?
Saint Louis, United States. In Hematology Am Soc Hematol Educ Program, Jan 2016
No abnormalities in other epigenetic regulators (DNMT3A, ASXL1), RNA splicing (SF3B1, SRSF2, URAF1, ZRSR2), transcription factors (RUNX1 or ETV6), or signaling (CBL, NRAS, KIT, JAK2, MPL) were detected.
Synthetic lethal targeting of oncogenic transcription factors in acute leukemia by PARP inhibitors.
Hong Kong, Hong Kong. In Nat Med, Dec 2015
Here we demonstrate that AML driven by repressive transcription factors, including AML1-ETO (encoded by the fusion oncogene RUNX1-RUNX1T1) and PML-RARα fusion oncoproteins (encoded by PML-RARA) are extremely sensitive to poly (ADP-ribose) polymerase (PARP) inhibition, in part owing to their suppressed expression of key homologous recombination (HR)-associated genes and their compromised DNA-damage response (DDR).
Myeloproliferative neoplasms: Current molecular biology and genetics.
Kermān, Iran. In Crit Rev Oncol Hematol, Dec 2015
Some other genes' location such as TET oncogene family member 2 (TET2), additional sex combs-like 1 (ASXL1), casitas B-lineage lymphoma proto-oncogene (CBL), isocitrate dehydrogenase 1/2 (IDH1/IDH2), IKAROS family zinc finger 1 (IKZF1), DNA methyltransferase 3A (DNMT3A), suppressor of cytokine signaling (SOCS), enhancer of zeste homolog 2 (EZH2), tumor protein p53 (TP53), runt-related transcription factor 1 (RUNX1) and high mobility group AT-hook 2 (HMGA2) have also identified to be involved in MPNs phenotypes.
Resistance in the Ribosome: RUNX1, pre-LSCs, and HSPCs.
United States. In Cell Stem Cell, Sep 2015
Now in Cell Stem Cell, Cai et al. (2015) show that loss-of-function mutations in RUNX1 reduce ribosome biogenesis and provide pre-LSCs a selective advantage over normal hematopoietic cells through increased stress resistance.
