A systems biology approach identifies effective tumor-stroma common targets for oral squamous cell carcinoma

Area of Science:

• Oncology
• Systems Biology
• Cancer Therapeutics

Background:

• Tumor initiation and progression involve complex interactions between cancer cells and the stromal microenvironment.
• The tumor microenvironment presents viable targets for therapeutic intervention.

Purpose of the Study:

• To introduce and validate the concept of common target perturbation (CTP) for enhanced cancer therapy.
• To identify a common molecular target within both oral cancer cells and their associated stroma.

Main Methods:

• A systems biology strategy combining experimental and computational approaches was employed.
• Iterative identification processes were used to pinpoint potential common targets.
• The efficacy of simultaneous versus unilateral perturbation of the identified target was assessed in vivo.

Main Results:

• Transforming growth factor-beta receptor III (TβRIII) was identified as a common epithelial-mesenchymal target in oral squamous cell carcinoma.
• Simultaneous perturbation of TβRIII in both oral cancer cells and carcinoma-associated fibroblasts significantly inhibited tumor growth.
• Dual-target perturbation demonstrated superior efficacy compared to unilateral perturbation of TβRIII.

Conclusions:

• Simultaneously targeting shared molecules in cancer cells and stroma offers a potent therapeutic strategy.
• The common target perturbation (CTP) concept provides a novel framework for discovering targets in combinatorial cancer therapies.
• This approach highlights the potential of considering the tumor and its adjacent stroma concurrently for improved cancer treatment.
