Fecal Proteomics Suggest Potential Biomarkers for Non‐Alcoholic Fatty Liver Disease and Steatohepatitis

PROTEOMICS – Clinical Applications, Volume 20, Issue 4, July 2026.
ABSTRACT Background and aims Non‐alcoholic Fatty Liver Disease (NAFLD) affects about a quarter of the world's population. Liver biopsy remains the gold standard for diagnosing the progressive form of NAFLD called Non‐alcoholic Steatohepatitis (NASH) but it is invasive, prone to sampling errors and observer variability, and impractical for widespread ...

Mapping the Substrate Specificity Landscape of PAD2 and PAD4 Enzymes

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
Protein citrullination, driven by peptidyl arginine deiminases (PAD2, PAD4), is linked to multiple diseases. Using a combinatorial peptide library and advanced mass spectrometry, we reveal distinct substrate selectivity profiles of PAD2 and PAD4. While PAD2 broadly citrullinates arginine‐containing peptides, PAD4 is highly sequence‐restricted, with ...
