Podoplanin (PDPN) is a unique transmembrane receptor that promotes tumor cell
motility. Indeed, PDPN may serve as a chemotherapeutic target for primary and
metastatic cancer cells, particularly oral squamous cell carcinoma (OSCC) cells
that cause most oral cancers. Here, we studied how a monoclonal antibody (NZ-1)
and lectin (MASL) that target PDPN affect human OSCC cell motility and viability.
Both reagents inhibited the migration of PDPN expressing OSCC cells at nanomolar
concentrations before inhibiting cell viability at micromolar concentrations. In
addition, both reagents induced mitochondrial membrane permeability transition to
kill OSCC cells that express PDPN by caspase independent nonapoptotic necrosis.
Furthermore, MASL displayed a surprisingly robust ability to target PDPN on OSCC
cells within minutes of exposure, and significantly inhibited human OSCC
dissemination in zebrafish embryos. Moreover, we report that human OSCC cells
formed tumors that expressed PDPN in mice, and induced PDPN expression in
infiltrating host murine cancer associated fibroblasts. Taken together, these
data suggest that antibodies and lectins may be utilized to combat OSCC and other
cancers that express PDPN.
