英文摘要a novel ph-responsive gene delivery system for tumor acidity-targeted pdna delivery is prepared by introducing a rapid charge-conversional zwitterionic copolymer to the positive surface of pei/pdna complexes through electrostatic interaction. the shielding system (oeal) consists of oligoethylenimine (oei), poly(l-aspartate) (pbla), and poly(l-lysine) (pll). the charge-conversional behavior of the oeal/pei/dna ternary complex is evaluated by zeta potential assay. the surface charges of the complexes can change from negative to positive in the ph range of 7.4-6.8. under a simulative in vivo environment, oeal/pei/dna exhibits promotion of cellular uptake by tumor cells and enhanced gene transfection efficiency because of its good charge-conversional properties. antitumor experiments further show that the ph-responsive charge-conversional system can mediate a therapeutic gene that can induce tumor apoptosis (pkh3-rev-casp-3) to achieve effective tumor inhibition. accordingly, oeal can be regarded as a promising tumor microenvironment-sensitive gene delivery shielding system for antitumor therapy.
