    Abstract: PURPOSE: A prostate cancer-specific siRNA delivery system is provided to selectively deliver siRNA to prostate cancer and to enhance siRNA efficiency. CONSTITUTION: A prostate cancer-specific siRNA delivery system is prepared by chemically binding siRNA and cell selectivity peptide to dextran. The siRNA delivery system selectively transfers the siRNA to a certain cell. The siRNA delivery system has a nanogel form which is mediated by hydrogen bond of the siRNA. [Reference numerals] (AA) Aptamer: disease specificity; (BB) Biocompatible polymer; (CC) SiRNA: gel formation and treatment effect

    Abstract: PURPOSE: An intracellular gene delivery composite containing a cationic polymer and cancer-targeting substances is provided to enable cancer therapy using various genes. CONSTITUTION: An intracellular gene delivery composite contains a cationic polymer and cancer-targeting substance. The cationic polymer has ester linkage, amide bond, disulfide bond, phosphate bond, or combination thereof. The cationic polymer is polyethylene imide(PEI), poly-L-lysine(PLL), chitosan, or dendrimer. The cancer-targeting substance is RGD peptide, NGR peptide, transferring, or folate. The gene is gDNA, cDNA, pDNA, mRNA, tRNA, rRNA, siRNA, miRNA, or antisense nucleotide. A method for preparing the composite comprises a step of conjugating the cancer-targeting substance to the cationic polymer using polyethylene glycol.

    Abstract translation: 目的:提供含有阳离子聚合物和癌症靶向物质的细胞内基因递送复合物,以使癌症能够使用各种基因进行治疗。 构成:细胞内基因递送复合物含有阳离子聚合物和癌症靶向物质。 阳离子聚合物具有酯键,酰胺键,二硫键,磷酸键或其组合。 阳离子聚合物是聚酰亚胺(PEI),聚-L-赖氨酸(PLL),壳聚糖或树枝状聚合物。 癌症靶向物质是RGD肽,NGR肽,转移或叶酸。 该基因是gDNA,cDNA,pDNA,mRNA,tRNA,rRNA,siRNA,miRNA或反义核苷酸。 制备复合物的方法包括使用聚乙二醇将癌症靶向物质与阳离子聚合物共轭的步骤。
