This study identifies four key immune-associated genes (CXCR4, LCP2, ITGAM, HLA-DRA) crucial for leukemia progression. These genes serve as diagnostic and prognostic biomarkers, offering potential therapeutic targets for immune-informed leukemia management.

Area of Science:

  • Hematology
  • Immunology
  • Genomics

Background:

  • Leukemia progression is significantly influenced by the immune microenvironment.
  • Regulatory gene networks governing immune activity in leukemia are not fully understood.
  • Identifying immune-associated hub genes can enhance biological insights and guide biomarker development.

Purpose of the Study:

  • To identify immune-associated hub genes in leukemia with diagnostic, prognostic, and functional relevance.
  • To elucidate the regulatory networks and functional impact of these hub genes in leukemia.

Main Methods:

  • Weighted Gene Co-expression Network Analysis (WGCNA) was used to identify immune-related hub genes from GEO datasets.
  • Validation of gene expression, diagnostic, and prognostic value in independent acute myeloid leukemia (AML) cohorts.
Keywords:

  • Bioinformatic assessment of genomic alterations and miRNA regulators, confirmed by luciferase assays.
  • Functional examination of hub genes through gene knockdown and overexpression experiments.

    • Main Results:

    • Four immune-associated hub genes (CXCR4, LCP2, ITGAM, HLA-DRA) were identified, significantly correlated with leukemia and immune infiltration.
    • These genes exhibited strong diagnostic performance (AUC 0.78-0.85) and a four-gene model consistently stratified survival across cohorts.
    • Shared upstream regulators, miR-27a-3p and miR-185-5p, were identified and validated.
    • Hub gene manipulation demonstrated significant effects on leukemia cell proliferation, clonogenicity, and migration.

    Conclusions:

    • A robust immune-associated gene module in leukemia was identified, with CXCR4, LCP2, ITGAM, and HLA-DRA serving as central hubs.
    • These genes possess consistent diagnostic and prognostic value and are coordinately regulated by shared miRNAs.
    • The findings suggest this four-gene signature as a potential biomarker set and therapeutic target for leukemia management.
