Specifically Targeting Muc16 For Fluorescence-Guided Surgery Of Pancreatic Ductal Adenocarcinoma, Kathryn M. Muilenburg

Theses & Dissertations

Pancreatic cancer is a lethal disease with a low 5-year survival rate and a high rate of resection recurrence. However, surgery remains the only treatment with curative potential for pancreatic cancer. Many factors such as high desmoplasia, a lack of intraoperative imaging, and micrometastatic disease contribute to the high rate of incomplete resections in pancreatic cancer. Fluorescence-guided surgery (FGS) is a potential intraoperative tool for application in surgical resection. FGS works through passive or active targeting of a free dye or dye-containing moiety (e.g. antibody, peptide, and nanoparticles) to specifically fluoresce the tumor compared to the surrounding normal, fibrotic, and …

Pharmacy Faculty Articles and Research

Selective targeting of cancer cells via overexpressed cell-surface receptors is a promising strategy to enhance chemotherapy efficacy and minimize off-target side effects. In this study, we designed peptide 31 (YHWYGYTPERVI) to target the overexpressed epidermal growth factor receptor (EGFR) in triple-negative breast cancer (TNBC) cells. Peptide 31 is internalized by TNBC cells through EGFR-mediated endocytosis and shares sequence and structural similarities with human EGF (hEGF), a natural EGFR ligand. Unlike hEGF, peptide 31 does not induce cell migration in TNBC cells. A novel conjugate of peptide 31 with doxorubicin (Dox) retains selectivity for TNBC cells and exhibits significant toxicity comparable …
