Abstract：
PURPOSE:Cell penetrating peptides (CPPs) were widely used as motifs for drug delivery to tumor. In former study, an RGD reverse sequence dGR was used to develop active-targeting liposome R8dGR-Lip, which showed well penetrating ability and treatment efficiency on glioma model. However, recurrence after tumor resection caused by post-operative residual cancer cells was a huge obstacle in tumor treatment. In consideration of the effective anti-cancer effect of PTX-R8dGR-Lip when treating glioma in former study, we decide to evaluate its pharmacodynamics on tumor resection models, which were more invasive and resistant. METHOD:In vitro, the effectiveness of PTX-R8dGR-Lip in reducing tumor initiating cell (TIC) was investigated using mammosphere formation. In vivo, the inhibition efficiency of PTX-R8dGR-Lip on C6 glioma recurrence and 4 T1 breast cancer recurrence model were evaluated, including tumor bioluminescence imaging, survival rate and immumohistochemical staining, etc.. RESULTS:C6 mammosphere formation rate of PTX-R8dGR-Lip group was 48.06 ± 2.72%, and 4 T1 mammosphere formation rate of PTX-R8dGR-Lip group was 39.51 ± 4.02% when PBS group was set as 100%. C6 and 4 T1 bioluminescent tumor resected model were established, then effectiveness of different PTX-loaded preparations were evaluated on these two models. PTX-R8dGR-Lip could obviously inhibit tumor recurrence, prolong survival rate and reduce tumor tissue invasion. CONCLUSION:PTX-R8dGR-Lip could reduce post-operative recurrence rate, prolong survival time, and decrease the proliferation of residual cancer cells through regulating the expression of recurrence-related cytokines.
