    • A purified monoclonal antibody, or an. antigen-binding portion thereof, which specifically binds to human clathrin heavy chain (CHC) is disclosed. The antibody, or antigen-binding portion, thereof, exhibits at least one, two, three, four, five, six, seven, or all eight of the following properties: (a) specifically binds to pancreatic adenocarcinoma cells; (b) binding to the cell surface and cytosol of cancer cells and tumor blood vessels; (c) internalized by CHC-expressing cells; (d) inhibiting tumor growth, invasion ability, migration, and angiogenesis; (e) inducing apoptosis in cancer cells and human umbilical vein endothelial cells; (f) inhibiting tumor growth and tumor blood vessels in pancreatic cancer in vivo; (g) suppressing epidermal growth factor, transferrin, and VEGF internalizations by cancer cells; and (h) suppressing hypoxia-inducible factor-1α expression and vascular endothelial growth factor secretion. Methods for inhibiting tumor cell growth and/or angiogenesis, and detecting cancer in a subject is also disclosed.
