This study developed a promising strategy for tumor-targeted co-delivery of Dacarbazine (DTIC) and miRNA 34a-loaded PHRD micelles (Co-PHRD) for combination treatment of MM.Methods: To construct the dual drug-loaded delivery system Co-PHRD, poly (L-arginine)-poly (L-histidine)-polylactic acid (PLA) was employed as a building block. In this system, poly (L-arginine) and PLA function as hydrophilic and hydrophobic blocks, respectively, which self-assemble into micelles in aqueous solution. Poly(L-arginine) and poly(L-histidine) are efficiently taken up by cells and perform efficient gene condensation, which facilitate the release of encapsulated miRNA 34a into the cytoplasm. Due to its lipophilic properties, PLA can effectively encapsulate DTIC. The polypeptide aptamer DR5-TAT (D21) was used as a targeting ligand. The properties of Co-PHRD and its in vitro release behaviour were characterized. Additionally, the synergetic effects of DTIC and miRNA 34a in melanoma therapy were investigated in vitro and in vivo.Results: Compared to DTIC treatment alone, Co-PHRD treatment exhibited 1.84-fold greater cytotoxicity in A375 cells, demonstrating that miRNA 34a enhanced the efficacy of DTIC. The particle size of Co-PHRD at an N/P ratio of 10 was 164.1 ± 4.5 nm, and the zeta potential of Co-PHRD was 27.3 ± 1.38 mV. The flow cytometry and CLSM results revealed both DTIC and miRNA 34a were avidly taken up by A375 cells at 1 h and 4 h in PHRD. In addition, in vivo results indicated that Co-PHRD micelles can significantly inhibit tumor growth without causing significant damage to major organs.Conclusion: Co-delivery of DTIC and miRNA 34a via polypeptide micelles showed synergistic effects against MM, offering a new strategy for gene and chemotherapy.Keywords: nano micelle, DTIC, miRNA 34a, co-delivery, malignant melanoma |
