Myeloid malignancies are heterogenous disorders characterized by distinct molecular drivers but share convergence of oncogenic signaling pathways and propagation by ripe pro-inflammatory niches. Here, we establish a comprehensive transcriptional atlas across the spectrum of myeloproliferative neoplasms (MPN) and secondary acute myeloid leukemia (sAML) through RNA-sequencing of 158 primary samples encompassing CD34+ hematopoietic stem/progenitor cells and CD14+ monocytes. Supported by mass cytometry (CyTOF) profiling, we reveal aberrant networks of PI3K/AKT/mTOR signalling and NFκB-mediated hyper-inflammation.

U2AF1 is a core component of spliceosome and controls cell-fate specific alternative splicing. U2AF1 mutations have been frequently identified in myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) patients, and mutations in U2AF1 are associated with poor prognosis in hematopoietic malignant diseases. Here, by forced expression of mutant U2AF1 (U2AF1 S34F) in hematopoietic and leukemic cell lines, we find that U2AF1 S34F causes increased reactive oxygen species (ROS) production.

Erythroleukemia, a complex myeloproliferative disorder presenting as acute or chronic, is characterized by aberrant proliferation and differentiation of erythroid cells. Although nootkatone, a sesquiterpene derived from grapefruit peel and Alaska yellow cedar, has shown anticancer activity predominantly in solid tumors, its effects in erythroleukemia remain unexplored. This study aimed to investigate the impact of nootkatone and its derivatives on erythroleukemia.

Hematopoietic stem cells must mitigate myriad stressors throughout their lifetime to ensure normal blood cell generation. Here, we uncover unfolded protein response stress sensor inositol-requiring enzyme-1α (IRE1α) signaling in hematopoietic stem and progenitor cells (HSPCs) as a safeguard against myeloid leukemogenesis. Activated in part by an NADPH oxidase-2 mechanism, IRE1α-induced X-box binding protein-1 (XBP1) mediated repression of pro-leukemogenic programs exemplified by the Wnt-β-catenin pathway.

Article Synopsis
- Chronic myelomonocytic leukemia (CMML) is a complex blood cell disorder that combines poorly functioning and overproducing blood cells, leading to various symptoms.
- The case study focuses on a 71-year-old man with severe CMML who experienced skin nodules that improved with treatment but later recurred, while avoiding progression to acute leukemia.
- The findings emphasize the importance of close monitoring and flexible treatment approaches for patients with CMML, especially those with skin involvement.
