PDPN and lip and oral cavity carcinoma: The QAgNP showed higher cytotoxicity in H-357 oral cancer cells and OSCC stem cells than normal epithelial cells compared to QC and Ag NPs.147 Moreover, Xiong et al. prepared an αPDPN-Ag2S probe by decorating a podoplanin (PDPN) antibody on the surface of NIR-II Ag2S quantum dots (QDs), and the results revealed that the αPDPN-Ag2S probe had a tumor-targeting ability and therapeutic efficacy of eliminating partial epithelial–mesenchymal transition (pEMT) with acceptable biological safety.
