Purpose of the Study:
- To review current research on modular organization and function of cancer transcriptional networks.
- To explore methods for identifying disease mechanisms and regulatory processes in cancer.
Main Methods:
- Analysis of biological processes using higher-level modules to identify disease signatures.
- Methods for identifying regulatory mechanisms within transcriptional modules.
- Comparative analysis of human data with model organisms for robust findings.
Main Results:
- Modular analysis can identify robust signatures of cancer mechanisms.
- Comparative analysis enhances the reliability of findings.
- Methods are being developed to understand transcriptional networks in cancer.
Conclusions:
- Understanding modular organization of transcriptional networks is key to cancer research.
- Comparative genomics and computational methods offer opportunities for improved cancer diagnosis and management.
- Challenges remain in generalizing findings from cells to tissues.
