Linking gut microbes and cancer
Exploiting Public Metagenomic Data to Uncover Cancer-Microbiome Relationships
Researchers will combine and standardize thousands of publicly available microbiome samples to find patterns showing how microbes relate to cancer, with a focus on colorectal cancer.

What this research studies
This project brings together large collections of publicly available microbiome sequencing data and harmonizes them so results can be compared across studies. The team will add information about bacterial shapes, physiologies, and predicted metabolic functions, and build tools to find similar microbial signatures. They will expand two curated resources (BugSigDB and curatedMetagenomicData), create workflows to process raw sequencing records, and run meta-analyses across thousands of studies. The goal is searchable, user-friendly databases and analysis tools that help researchers spot reproducible microbe–cancer links.
Who could benefit from this research
Good fit: People with colorectal or other cancers who can provide stool, tumor, or other microbiome samples, or whose existing sequencing data could be shared, would be most relevant to this work.
Not a fit: Patients without available microbiome samples or whose cancers are unlikely to involve microbial factors are unlikely to see direct benefits from this database-focused work in the short term.
Why it matters
Potential benefit: If successful, the work could reveal consistent microbial patterns tied to cancer risk or treatment response that help guide new diagnostics or therapies.
How similar studies have performed: Previous studies have linked gut microbes to colorectal cancer and to responses to immunotherapy, but combining and standardizing thousands of public datasets at this scale is largely new.
