## Abstract

Biomedical omics resources are often treated as separate datasets, which fragments insight and limits discovery of shared mechanisms. Crossing datasets from Common Fund programs can reveal robust molecular signatures that span distinct biological contexts, improve reproducibility, and connect molecular changes to physiology. In this report we combined three complementary geneset libraries: the GlyGen Glycosylated Proteins library, which supplies sets of proteins modified by specific glycans; the GTEx TissueSpecific Aging Signatures library, which captures genes upregulated in blood of younger versus older individuals; and the LINCS L1000 CRISPR KO Perturbation Signatures library, which provides genes downregulated following POLE knockout in PC3 cells. By intersecting one gene set from each library we identified a single crossing in which twenty genes appear in all three sets, representing a maximal shared component among all evaluated combi nations. Functional enrichment of this intersecting set highlighted coordinated downregulation of hemostasis and coagulation pathways together with cholesterol and lipid metabolism, implicating a shift in both clotting and lipid biology that aligns with agerelated metabolic changes and the POLE perturbation. The deepdive literature synthesis described these genes as secreted glycoproteins involved in extracellular transport, matrix
remodeling, and innate immunity, many of which are linked to metabolic disturbance, vascular stiffening  and chronic lowgrade inflammation. Together the findings illustrate how integrating diverse Common Fund resources can uncover biologically meaningful overlaps that may inform therapeutic strategies targeting coagulation and lipid dysregulation.
