This study compared the effectiveness of PEI-CP and PC-CP for liver cancer therapy, finding that PC-CP showed better infiltration and transplantation efficiencies, reduced foreign body reactions, and superior clinical efficacy compared to PEI-CP. The functional mechanism of PC-CP was also found to have a more significant impact on mTOR, P-Ak, LC3, and P53, indicating that PC-CP may be a better choice for future LC therapy.
The aim of this study was to test an effective nano-pole capsule loaded cis-platinum (CP) transplantation device for liver cancer (LC) therapy. A novel nano-pole capsule was designed as a new vector for storing CP. HepG2 cells and a B6/J mouse model were used to test the efficiency of polyethyleneimine-cis-platinum (PEI-CP) and poly-chitosan-cis-platinum (PC-CP). Infiltration efficiency and transplantation efficiency tests were performed to study the performance of the delivery system, and fibroblast reactions and macrophage numbers were observed, to test for immune rejection and foreign body reactions. The apoptosis rate and tumor diameter of hepatocellular carcinoma cells were used to evaluate the effect of the tumor therapy. We also studied the functional mechanism of different CP delivery systems. The infiltration and transplantation efficiencies of PC-CP were higher than that of PEI-CP; Less foreign body reaction appeared in PC system, with less fibroblast reaction and lower macrophage reaction. The clinical efficacy of PC-CP in terms of tumor apoptosis and diameter reduction was superior to that of PEI-CP. We demonstrated that PC-CP had a more significant alteration effect on mTOR, P-Ak, LC3 and P53. The PC system can better deliver and release drugs than PEI-CP, and may be a P: 49249253 194 O M 25 O t 2021 084735 better choice for LC therapy in the future. Co
