Insights

We developed a new computational method (SnpDR) to find new cancer drug targets. This method identified extracellular matrix (ECM) targets and repositioned drugs for lung squamous cell carcinoma (LSCC).

Area of Science:

  • Computational biology
  • Proteomics
  • Cancer research

Background:

  • Cancer subtype proteomic comparisons reveal heterogeneity and therapeutic targets.
  • Drug repositioning requires effective computational frameworks.

Purpose of the Study:

  • To present a novel computational framework, signature-network-perturbation-based drug repositioning (SnpDR).
  • To identify subtype-specific vulnerabilities and potential therapeutic targets in lung squamous cell carcinoma (LSCC).

Main Methods:

  • Integrated proteomic and pharmacogenomic data using differential modular analysis.
  • Constructed drug response networks and performed multiscale perturbation response scanning.
  • Applied SnpDR to compare lung adenocarcinoma and LSCC proteomic landscapes.

Main Results:

  • Identified the extracellular matrix (ECM) module as a central hub in LSCC.
  • Discovered LAMA1 as a novel drug target.
  • Validated Fingolimod and Piperlongumine as effective repositioned drugs inhibiting LSCC growth, proliferation, and migration.

Conclusions:

  • SnpDR is a powerful framework for identifying subtype-specific therapeutic vulnerabilities.
  • ECM-targeted interventions show promise for LSCC treatment.
  • Systems biology approaches accelerate precision oncology discovery.
