Insights

This study identifies six immune cell-related biomarkers (SLC27A2, ACOX2, PECR, CRAT, FADS1, ELOVL5) for cutaneous squamous cell carcinoma (CSCC). These biomarkers show potential for CSCC treatment and drug development.

Area of Science:

  • Oncology
  • Immunology
  • Genomics

Background:

  • Cutaneous squamous cell carcinoma (CSCC) is a prevalent skin cancer.
  • Immune cell involvement is critical in CSCC development and progression.
  • Identifying immune-related biomarkers is crucial for effective CSCC treatment strategies.

Purpose of the Study:

  • To screen and identify novel immune cell-related biomarkers for CSCC.
  • To explore the therapeutic potential of identified biomarkers and associated drugs.
  • To validate the expression of biomarkers in CSCC tissues.

Main Methods:

  • Gene set variation analysis (GSVA) and immune infiltration analysis to identify key immune cells.
  • Weighted gene co-expression network analysis (WGCNA) to find immune cell-related genes.
  • Differential gene expression analysis, Venn diagrams, and protein-protein interaction (PPI) networks to identify candidate biomarkers.
  • Receiver operating characteristic (ROC) curves for biomarker validation and drug discovery using the DRUGBANK database.
  • Real-time quantitative polymerase chain reaction (RT-qPCR) for expression verification.

Main Results:

  • Four key immune cells (M0 macrophages, resting dendritic cells, resting mast cells, activated mast cells) were identified.
  • Six potential biomarkers (SLC27A2, ACOX2, PECR, CRAT, FADS1, ELOVL5) were screened and validated.
  • Biomarker high expression correlated with immune checkpoint expression.
  • Ten potential therapeutic drugs targeting these biomarkers were identified.
  • Biomarkers showed lower expression in CSCC tumor tissues compared to normal tissues.

Conclusions:

  • Six immune cell-related biomarkers (SLC27A2, ACOX2, PECR, CRAT, FADS1, ELOVL5) were identified for CSCC.
  • These biomarkers offer a theoretical basis for CSCC treatment and targeted drug development.
  • Further research into these biomarkers could lead to novel therapeutic strategies for CSCC.
