Li lab identifies metabolite and protein biomarkers to identify prostatic inflammation with lower urinary tract symptoms

By nickwiecien

Lower urinary tract symptoms (LUTS) are common among aging men. Since inflammation is one of its indicators, it is plausible that urinary metabolite and protein biomarkers could be used to identified and diagnose inflammation-induced LUTS. In this study, the Li lab used Mass spectrometry (MS)-based multi-omics analysis to characterize the urine metabolome and proteome in a mouse model. By comparing their findings with urinary biomarkers associated with LUTS in older men, they identified creatine, haptoglobin, immunoglobulin kappa constant and polymeric Ig receptor as conserved biomarkers for prostatic inflammation associated with LUTS.

Li lab collaboration explores noninvasive markers in prostate disease diagnosis

By nickwiecien

A recent collaboration between the labs of Lingjun Li and William Ricke explores the relationship between prostatic hyperplasia and related lower urinary tract symptoms in aging males and how noninvasive markers could be helpful in disease diagnosis. This proteomics study used a mouse model of hormone-induced urinary dysfunction to gain insight into the disease and supports the concept of noninvasive urinary biomarkers being a successful route for prostate disease diagnostics.
