Background: Methylmalonic acidaemia (MMA) is a genetic metabolic disorder caused by congenital defects that may result in multisystem damage. However, MMA complicated with acute myeloid leukemia (AML) is very rare.
Case Presentation: Here, we report a case of MMA with AML in a boy aged 7 years and 6 months. The boy was screened for MMA after birth and received long-term treatment with dietary control, vitamin B12, and L-carnitine. He was readmitted at the age of 7 years and 6 months with systemic bleeding spots and was diagnosed with AML by bone marrow cytology. When the diagnosis was clear, the patient received chemotherapy in addition to maintenance treatment for MMA. His blood routine, liver and kidney function, blood biochemistry, blood glucose, blood lipids, lactic acid and blood ammonia were monitored continuously. Bone marrow cytology one month after starting chemotherapy showed complete remission. Sorafenib was also added during chemotherapy and was discontinued 1 year after completion of chemotherapy. At the end of chemotherapy, he chose venetoclax for consolidation, and to date, the patient's condition is stable, with sustained CR and no relapse.
Conclusion: MMA combined with AML is rare. The prevention of infection, comprehensive assessment of nutritional status, continuous monitoring of related indicators and overall situation should be prioritized and comprehensive and individualized treatment approaches are paramount.

N6-methyladenosine (mA) modification, primarily regulated by methyltransferase-like protein 3 (METTL3), plays a pivotal role in RNA metabolism and leukemogenesis. However, the post-translational mechanisms governing METTL3 stability and function remain incompletely understood. Given the widespread occurrence of O-GlcNAcylation on nuclear and cytosolic proteins, we hypothesized that METTL3 might undergo O-GlcNAcylation, thereby influencing its stability and oncogenic function in myeloid malignancies.

Background: Benzene, a ubiquitous industrial chemical, is a well-established environmental toxin associated with hematological disorders such as myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML), which are characterized by impaired hematopoiesis and bone marrow failure. This study investigates the role of ferroptosis, an iron-dependent form of cell death, in benzene-induced hematotoxicity, focusing on the repression of glutathione peroxidase 4 (GPX4), a critical regulator of ferroptosis.
Materials And Methods: Male C57BL/6 mice were exposed to benzene at various doses over six weeks.

The median life expectancy of people with Down syndrome has increased substantially over the past several decades, from 4 years in 1970 to 53 years in 2010. Despite the recent improvement in survival, there is little data about the prevalence of age-related diseases, including age-related malignancies, and the impact of standard cancer treatments on cardiovascular health. We retrospectively reviewed medical records for age- and sex-matched patients ≥ 15 years old with and without Down syndrome using the TriNetX platform to identify the prevalence of malignancies and explore cardiovascular outcomes after treatment with anthracyclines.

Venetoclax plus azacitidine is recognized as standard of care for patients with acute myeloid leukemia (AML) ineligible for intensive chemotherapy (IC). However, some patients may still not be treated with venetoclax combinations due to frailty concerns. We evaluated efficacy and safety of venetoclax plus azacitidine vs.
