Abstract

Insights

LAGE3 (L Antigen Family Member 3) overexpression is linked to poor prognosis in clear cell renal cell carcinoma (ccRCC). This gene may serve as an independent survival predictor and a target for novel ccRCC immunotherapies.

Area of Science:

  • Oncology
  • Immunology
  • Genetics

Background:

  • Clear cell renal cell carcinoma (ccRCC) is the predominant kidney cancer globally.
  • The role of L Antigen Family Member 3 (LAGE3) in ccRCC remains largely unexplored.
  • Understanding LAGE3's function is crucial for advancing ccRCC treatment.

Purpose of the Study:

  • To investigate the clinical significance of LAGE3 in ccRCC.
  • To elucidate the biological functions of LAGE3 within the ccRCC tumor microenvironment.
  • To assess LAGE3 as a potential prognostic biomarker and therapeutic target.

Main Methods:

  • Utilized RNA-sequencing data and clinical information from TCGA and GEO databases for ccRCC patients.
  • Employed ESTIMATE, quanTiseq, and xCell algorithms to analyze immune cell infiltration.
  • Conducted multivariate analysis and functional enrichment analysis.

Main Results:

  • LAGE3 overexpression correlated with unfavorable clinical-pathological features and poorer survival outcomes in ccRCC cohorts.
  • LAGE3 was identified as an independent determinant of survival in ccRCC patients.
  • Functional analysis suggested LAGE3 influences humoral immune responses and receptor-ligand activity, positively impacting the cancer-immunity cycle and immune cell infiltration.

Conclusions:

  • LAGE3 serves as a significant independent survival predictor for ccRCC.
  • LAGE3 expression is associated with immune activity within the tumor microenvironment.
  • Targeting LAGE3 may offer potential for developing new immunotherapeutic strategies for ccRCC.
