Gene Regulation Survey Spans 4,749 Prognostic Modules across 32 Cancer Types

View Original View Raw

Summary

Researchers at the Mount Sinai Center for Transformative Disease Modeling used multi-omics genetic analysis tools to identify 4,749 gene clusters, termed “prognostic modules,” which significantly influence the progression of 32 different types of cancer. The study identified critical genes and their complex relationships that either halt or promote cancer progression, which could lead to improved patient outcomes. The authors used a multi-omics approach and advanced systems biology approaches to analyze more than 10,000 patient samples from the Cancer Genome Atlas, and used rigorous network methods to identify and validate the gene clusters with a significant impact on cancer prognosis. The study found that network modules formed preserved module clusters in chromosomal hotspots, and that there are also cancer-type-specific prognostic modules that participate in cancers-specific biological processes. The researchers have shared the networks, modules, prognostic features, and their functional annotations on open-source websites for scientists to use.
