Objective: To investigate the inhibited effect of epigallocatechin-3-gallate (EGCG) on the expression of NPM1 in IMS-M2 cells harboring the NPM1 mutations.

Methods: Cell proliferation assay was performed to test the effects of EGCG on cell growth of IMS-M2 cells harboring the NPM1 mutations. Western blot analysis were performed to test the protein expression of NPM1, AKT, those associated with apoptosis.

Results: EGCG can down-regulate the expression of NPM1 in IMS-M2 cells harboring the NPM1 mutations. Moreover, EGCG also suppressed the cell proliferation and induced apoptosis in IMS-M2 cells.

Conclusions: The results suggested that EGCG could be considered as a reagent for treatment of AML patients with NPM1 mutations.

Background: The complexity of acute myeloid leukemia (AML) is increasingly recognized through the identification of distinct subgroups, including those with an APL-like immunophenotype characterized by the absence of CD34 and HLA-DR expression, which is widely recognized as a representative immunophenotype in acute promyelocytic leukemia (APL). This study sought to understand the clinical, molecular, and prognostic differences between AML patients with and without this phenotype.

Methods: This study retrospectively analysed 191 de novo non-M3 AML patients and identified 32 patients with the CD34HLA-DR phenotype resembling APL-like immunophenotype, considered as the experimental group.

Context.—: Blasts in myelodysplastic syndromes (MDSs) typically have a primitive myeloid immunophenotype (CD34+CD117+CD13+CD33+HLA-DR+). On rare occasions, blasts were found to be CD34 negative or minimally expressed in a presumptive MDS.

Acute myeloid leukemia (AML) currently lacks a definitive cure. Studies have highlighted the involvement of SYTL4 expression levels in neoplasms, yet its specific roles in AML remain unexplored in the literature. Utilizing the TCGA and XENA databases, this study investigated SYTL4 expression levels in AML and identified associations between SYTL4 overexpression and clinicopathological features, prognosis, and immune infiltration in AML patients through genomic analysis.

Mutations in the Nucleophosmin-1 (NPM1) gene are among the most common molecular aberrations in acute myeloid leukemia (AML). Various studies have established mutant NPM1 (mNPM1) as a faithful molecular measurable residual disease (MRD) marker with prognostic significance. Assessment of prognostic mNPM1 is included in the European LeukemiaNet (ELN) recommendations on MRD detection in AML.

Article Synopsis
  • * A study examined HIF-1α levels in the bone marrow of 29 newly diagnosed NPM1FLT3-ITD normal karyotype AML patients and found that over half exhibited strong HIF-1α expression, correlating this with increased relapse rates and shorter relapse-free survival (RFS).
  • * High HIF-1α levels might serve as a useful prognostic biomarker for predicting poor RFS and resistance to cytarabine in NPM1FLT
