Poor prognosis of SRSF2 gene mutations in patients treated with VEN-AZA for newly diagnosed acute myeloid leukemia. (PubMed, Leuk Res)

This study aimed to evaluate the impact of Spliceosome mutations in patients treated with Venetoclax and Azacitidine for newly diagnosed AML. This negative prognostic impact remained true in our multivariate analysis. We believe this finding should warrant further studies aimed at overcoming this negative impact.

What is new in acute myeloid leukemia classification? (PubMed, Blood Res)

AML cases defined by differentiation (WHO2022) and AML not otherwise specified (ICC) are categorized as lacking specific defining genetic abnormalities, WHO2022 labels this as a myeloid neoplasm post cytotoxic therapy (MN-pCT), described as an appendix after specific diagnosis. Similarly, in ICC, it can be described as "therapy-related", without a separate AML category.

Accelerated DNA replication fork speed due to loss of R-loops in myelodysplastic syndromes with SF3B1 mutation. (PubMed, Nat Commun)

Importantly, histone deacetylase inhibition using vorinostat restores R-loop formation, slows down DNA replication forks and improves SF3B1-mutated erythroblast differentiation. In conclusion, loss of R-loops with associated DNA replication stress represents a hallmark of SF3B1-mutated MDS ineffective erythropoiesis, which could be used as a therapeutic target.

Differential prognostic values of the three AKT isoforms in acute myeloid leukemia. (PubMed, Sci Rep)

Curiously, although modestly varying among AML samples, a high AKT1 expression shows in contrast as a strong predictor of a better patient outcome. These data suggest that AKT3 and AKT1 expressions have strong, yet opposite, prognostic values.

However, RUNX1 co-mutation was associated with an increased risk of post-alloSCT relapse (HR 88.0, P = 0.02), whereas melphalan-based conditioning was associated with a decreased relapse-risk (HR 0.02, P = 0.01). We conclude that mBCOR is a high-risk feature across MDS/AML and that alloSCT improves survival in this population.

Furthermore, the high frequency of somatic U2AF1 mutations in patients with young-onset MDS suggests the presence of a distinct MDS subtype.

Global analysis of binding sites of U2AF1 and ZRSR2 reveals RNA elements required for mutually exclusive splicing by the U2- and U12-type spliceosome. (PubMed, Nucleic Acids Res)

The class switch of introns by a single mutation and the bias against G at the -1 position of U12-type 5' splice site support the notion that the identities of nucleotides in exonic regions adjacent to splice sites are fine-tuned to avoid recognition by the U2-type spliceosome. These findings may shed light on the mechanism of selectivity in U12-type intron splicing and the mutations that affect splicing.

This study showed and association between high-risk cytogenetics and worse prognosis in AML, but no association was observed between molecular risk and AML morbimortality. Further studies with a bigger population and longer follow-up should be conducted in Latin America in order to better clarify and delve deeper into the results reported in this cohort.

Characterization of Cases with the Rare Cytogenetic Abnormality I(7)(p10) Reveals an Association with IDH2 Mutated Acute Myeloid Leukemia (ASH 2023)

(1) The rare but recurrent cytogenetic aberration i(7)(p10) is mainly found in AML, where associations with mutations in IDH2, DNMT3A and BCOR were observed. By contrast, other AML-defining mutations ( NPM1, FLT3-ITD, CEPBA) were largely absent, further no defining fusions/rearrangements or a complex karyotype were detected. (2) The vast majority of patients were female and younger than patients with IDH2 mutation without i(7)(p10).

Lessons of Nature in Trisomy-8 MDS and AML: Determinants of Clonal Drive (ASH 2023)

8 itself. Indeed, we found transcriptomic changes pertinent to +8 MDS whose role in driving leukemogenesis and interaction with specific myeloid drivers needs to be confirmed by future experimentations on cellular and murine models.

Genomic Analyses Unveil the Pathogenesis and Inform on Therapeutic Targeting in KMT2A-PTD AML (ASH 2023)

Given the results obtained with menin inhibitors in KMT2A-rearranged and NPM1-mutated AML, our findings open an opportunity for exploiting a therapeutic vulnerability in all HOX-AML including KMT2A-PTD AML or AML with high MEN1 expression. Since HOX-AML highly express genes according to the HOX differentiation profile, stage-specific surface proteins coded by these genes would be promising targets.

NGS Profile and the Mathematical Prediction Model for Venetoclax Combination Therapy in HM-Screen-Japan 02 Study (ASH 2023)

Introduction Azacitidine and venetoclax combination therapy (Aza/Ven) is a novel strategy for acute myeloid leukemia (AML). Our mathematical model, involving gene mutations and WT1, could efficiently predict the response of Aza/Ven, which may support the selection of 1 st line treatment. In conclusion, our study revealed the genetic landscape of real-world Aza/Ven therapy and provided a potential prognostic model.
