RT Journal Article SR Electronic T1 Infer disease-associated microbial biomarkers based on metagenomic and metatranscriptomic data JF bioRxiv FD Cold Spring Harbor Laboratory SP 2021.09.13.460160 DO 10.1101/2021.09.13.460160 A1 Zhaoqian Liu A1 Qi Wang A1 Dongjun Chung A1 Qin Ma A1 Jing Zhao A1 Bingqiang Liu YR 2021 UL http://biorxiv.org/content/early/2021/10/21/2021.09.13.460160.abstract AB Unveiling disease-associated microbial biomarkers is crucial for disease diagnosis and therapy. However, the heterogeneity, high-dimensionality, and large amounts of microbial data bring tremendous challenges for fundamental characteristics discovery. We present IDAM, a novel method for disease-associated biomarker inference from metagenomic and metatranscriptomic data, without requiring prior metadata. It integrates gene context conservation (uber-operon) and regulatory mechanism (gene co-expression patterns) through a mathematical graph model. We applied IDAM to inflammatory bowel disease associated matched metagenomic and metatranscriptomic datasets, which showed superior performance in biomarker inference.
