Abstract
Sorafenib (SF) is a first-line drug for the treatment of hepatocellular carcinoma (HCC) in clinical practice. However, acquired drug resistance tremendously limits the clinical efficacy of sorafenib in treating HCC, which has attracted great attention. PDL1 plays a crucial role in the drug resistance of HCC. Here, a codelivery system based on poly-SS-lysine modified chitosan (TAT-C-SS-P) was established and was applied to deliver sorafenib and PDL1-siRNA for synergetic HCC therapy. The successful synthesis of TAT-C-SS-P was confirmed by 1H NMR. Additionally, sorafenib and PDL1-siRNA were successfully transported into the cells as the decreased expression of VEGF and PD-L1 by administrated with TAT-C-SS-P@SF@ PDL1-siRNA. Simultaneously, the expression of pro-apoptosis proteins cyt-c and Bax was prominently augmented, whereas the expression of anti-apoptosis protein Bcl-2 was decreased. The reduced expression of PDL1 resulted in the downregulation of P-GP and MRP1, which contributed to more sorafenib aggregation in tumor cells. Moreover, TAT-C-SS-P@PDL1-siRNA@SF efficiently promotes apoptosis of HepG2-SI cells, as the apoptosis rate rised to 73 %. A sorafenib-insensitive model was established to evaluate in vivo antitumor effect of TAT-C-SS-P@PDL1-siRNA@SF. TAT-C-SS-P@PDL1-siRNA@SF showed a tumor inhibition rate of 90.2 ± 3.5 % and no significant decrease in body weight. Taken together, our study provided compelling evidence that TAT-C-SS-P@PDL1-siRNA@SF has great potential application in the treatment of HCC clinically.
