The assay library covers many key proteins involved in cancer-related pathways and molecular functions, such as the cell cycle/p53, transforming growth factor β (TGF-β), JAK-STAT, phosphatidylinositol 3-kinase (PI3K)-AKT, EGFR, and Wnt pathways, as well as adherent junctions, extracellular matrix (ECM)-receptor interactions, and apoptosis (Data S2B). Here, TGFB1 is linked to cancer.
