Molecular Targeting of Cancer-Associated PCNA Interactions in Pancreatic Ductal Adenocarcinoma Using a Cell-Penetrating Peptide

Pancreatic ductal adenocarcinoma is a particularly difficult cancer to treat due to a lack of effective screening or treatment. Pancreatic cancer cells exhibit high proliferating cell nuclear antigen (PCNA) expression, which is associated with poor prognosis. PCNA, an important nuclear DNA replication and repair protein, regulates a myriad of proteins via the interdomain connector loop. Within this region, amino acids 126-133 are critical for...
