Abstrakt: Background: Overexpression of mucin-5AC (MUC5AC) makes it a targetable biomarker in pancreatic cancer. The present study evaluated tumor targeting with a MUC5AC antibody conjugated to a near-infrared dye in a patient-derived orthotopic xenograft (PDOX) mouse model.
Materials and Methods: MUC5AC monoclonal antibody was conjugated to the near-infrared dye IRDye800CW to synthesize MUC5AC-IR800. PDOX models were established by implanting a high-MUC5AC-expressing patient-derived pancreatic tumor on the pancreas of nude mice. After 4 weeks of PDOX tumor growth, mice were imaged after receiving MUC5AC-IR800 (75 μg) intravenously.
Results: In the PDOX models, MUC5AC-IR800 selectively and brightly targeted the pancreatic tumor (tumor to background ratio: 2.46±0.465).
Conclusion: MUC5AC-IR800 provides distinct visualization of pancreatic tumors. MUC5AC-IR800 may be used clinically in the future to improve pancreatic cancer resection. This novel fluorescent probe is also promising for targeting of pre-malignant pancreatic lesions with subsequent resection under fluorescence guidance.
