The purpose of this project is to demonstrate what genes are important and serve as bottlenecks in various different parts of the breast cancer pathway. Scientists already understand essential genetic biomarkers in the cancer pathway like BRCA1 and BRCA2 are essential for various breast cancer pathways. It’s important to know the system and understand how the networks intervene with each other. We can identify bottlenecks in the breast cancer network by using Graph Network theory. We can pinpoint critical genes in the metabolome through this work.
