The study aims to investigate the role of polyamines in pancreatic cancer and evaluate the efficacy of polyamine blockade with anti-PD-1 therapy.
Utilized an orthotopic mouse model of pancreatic ductal adenocarcinoma with syngeneic GFP-Luc2 cells.
Administered polyamine blockade therapy (PBT) consisting of DFMO and Trimer44NMe alongside anti-PD-1 therapy.
Monitored tumor progression through in vivo bioluminescence imaging.
Analyzed immune cell populations using tumor multiplexing and flow cytometry.
Combination of PBT and anti-PD-1 therapy significantly reduced tumor mass.
Increased infiltration of anti-tumor immune cells was observed.
Enhanced systemic anti-tumor immune responses were noted.
