Abstract

Insights

Tyrosine-Protein Kinase Src (SRC) is upregulated in many cancers and linked to poor prognosis. This study reveals SRC’s association with immune cell infiltration and tumor characteristics, suggesting its potential as a prognostic biomarker and therapeutic target.

Area of Science:

  • Oncology
  • Molecular Biology
  • Immunology

Background:

  • Tyrosine-Protein Kinase Src (SRC) is vital for cell signaling pathways.
  • SRC dysregulation correlates with advanced cancers and poor prognosis.
  • The prognostic value and immune role of SRC across diverse cancers are not fully understood.

Purpose of the Study:

  • To investigate SRC expression in various cancers.
  • To determine the prognostic significance of SRC in pan-cancer analysis.
  • To explore SRC's relationship with the tumor immune microenvironment.

Main Methods:

  • Utilized the Sangerbox database for differential SRC expression analysis.
  • Performed Cox risk ratio and Kaplan-Meier analyses for survival outcomes.
  • Assessed SRC's association with immune genes, mutation load, and microsatellite instability.

Main Results:

  • SRC expression is upregulated in multiple tumor types compared to normal tissues.
  • SRC levels correlate with overall survival (OS) in specific cancers (e.g., LIHC, PRAD).
  • SRC is associated with tumor mutation burden, microsatellite instability, and immune cell infiltration in various cancers.

Conclusions:

  • SRC may serve as a prognostic biomarker and therapeutic target in oncology.
  • SRC expression is linked to immune infiltration and influences cancer patient prognosis.
  • SRC warrants further investigation for its role in cancer development and immune response.
