INTRODUCTION: Ulcerative colitis (UC) is a chronic disease with rising incidence and unclear etiology. Deep molecular phenotyping by multi omics analyses may provide novel insights into disease processes and characteristic features of remission states. METHODS: UC pathomechanisms were assessed by proteome profiling of human tissue specimen, obtained from five distinct colon locations for each of the 12 patients included in the study. Systemic disease-associated alterations were evaluated thanks to a cross-sectional setting of mass spectrometry-based multi-omics analyses comprising proteins, metabolites and eicosanoids of plasma obtained from UC patients during acute episodes and upon remission in comparison to healthy controls...
