Abstract Analyzing single omics and integrating multimodal omics datasets to capture functional dysregulation in disease remains challenging. Here, we propose a bioinformatics framework that leverages curated datasets of protein complexes (‘complexome’) as a foundation for proteomics data integration. Available for human and other model organisms, the complexome provides a global view of cellular function, enabling queries with proteomics datasets.

Abstract Pancreatic β-cells maintain glucose homeostasis by secreting insulin in response to rising blood glucose, a process fueled by mitochondrial ATP production. Iron, a core cofactor in the electron transport chain, is essential for this metabolic coupling. While the cytotoxic effects of iron overload are well known, the role of iron sufficiency during β-cell development remains unclear. Here, we identify a maturation-dependent requirement for iron in mouse and human β-cells.

Mass spectrometry data analysis has long been limited to known molecules and exact matches. In a recent manuscript, a scalable search algorithm is proposed for uncovering both known compounds and novel molecular variants, enabling insights into natural product biosynthesis.
