Tumor-Colonizing E. coli Expressing Both Collagenase and Hyaluronidase Enhances Therapeutic Efficacy of Gemcitabine in Pancreatic Cancer Models
Desmoplasia is a hallmark feature of pancreatic ductal adenocarcinoma (PDAC) that contributes significantly to treatment resistance.Approaches to enhance drug delivery into fibrotic PDAC tumors continue to be an important unmet need.In this study, we have engineered a tumor-colonizing color touch 7/97 E.coli-based agent that expresses both collagen
