PODXL overexpression is an independent predictor of progression, metastasis, and poor outcome. We recently immunized mice with recombinant human PODXL, which was produced using LN229 glioblastoma cells, and produced a clone PcMab-47 that could be used for investigating PODXL expression by flow cytometry and immunohistochemical analysis. Herein, we produced a human-mouse chimeric PcMab-47 (chPcMab-47) and investigated its antitumor activity against PODXL-expressing tumors. chPcMab-47 reacted with LN229, LN229/PODXL, and Chinese hamster ovary (CHO)/PODXL cells, but it did not react with CHO-K1 or PODXL-knockout LN229 cell line (PDIS-13). chPcMab-47 exerted antitumor activity against a mouse xenograft model using CHO/PODXL. Furthermore, chPcMab-47 was reactive with colorectal cancer cell lines such as HCT-15, Caco-2, HCT-8, and DLD-1. chPcMab-47 also exhibited antitumor activity against a mouse xenograft model using HCT-15. These results suggest that chPcMab-47 could be useful for ant...
