Compared to conventional methods, OSaMPle increased bacterial peptide identifications by 3.2x and protein identifications by 1.7x. Using OSaMPle, we analyzed mouth rinse samples from IBD patients and found significant shifts in bacterial protein expression. 3/3 #Metaproteomics

We developed OSaMPle (Optimized Salivary MetaProteomic sample analysis workflow) to enrich bacterial cells from saliva and mouth rinse, reducing host contamination and enabling deeper oral metaproteomics. 2/3

The oral microbiome is linked to various inflammatory conditions, including IBD. However, analyzing functional changes at the protein level has been challenging due to host protein interference. 🧵 1/3

I couldn’t be prouder—this is the work of the very first master's student that I've supervised. Salivary metaproteomics is tricky due to host/debris interference. Yuan et al. developed a microbial cell enrichment step and achieved cleaner data with better insights. www.nature.com/articles/s41...

Systematic Metaproteomics Mapping Reveals Functional and Ecological Landscapes of Human Gut Microbiota Responses to Therapeutic Drugs Therapeutic compounds significantly alter the composition of the gut microbiota, yet their functional and ecological impacts, particularly at the protein level, remain largely unexplored. In this stud...

🚨 We mapped 4.6M #microbial protein responses to 312 compounds, uncovering 3 distinct functional gut #microbiome states and revealing how neuropharma triggers deep shifts (lower functional redundancy, higher #AMR proteins).

PhyloFunc: phylogeny-informed functional distance as a new ecological metric for metaproteomic data analysis - Microbiome Background Beta-diversity is a fundamental ecological metric for exploring dissimilarities between microbial communities. On the functional dimension, metaproteomics data can be used to quantify beta-...

🦠 In #metaproteomics, proteins are often treated as independent features, ignoring their ecological relationships.
🌱 We developed PhyloFunc, a beta diversity metric that integrates phylogeny into functional distance calculations, offering a more ecologically meaningful way to compare microbiomes.
