Abstract
We previously reported that folate-polyethylene glycol (PEG)-appended dendrimer (generation 3)/α-cyclodextrin conjugate (Fol-PαC (G3)) shows folate receptor-α (FR-α)-overexpressing tumor cell-selective in vitro siRNA transfer activity. However, Fol-PαC (G3)/siRNA complex did not induce a significant in vivo RNAi effect after intravenous administration to tumor-bearing mice, possibly resulting from immediate dissociation of the complex in blood. Herein, to develop the novel siRNA carrier having high blood circulating ability, high in vivo siRNA transfer activity, and high safety profile, we newly prepared Fol-PαCs with higher generation (G4) and evaluated their potential as tumor-targeting siRNA carriers in vitro and in vivo. Fol-PαC (G4, average degree of substitution of α-cyclodextrin (DSC) 2.9, average degree of substitution of folate-PEG (DSF) 2)/siRNA complex had the prominent RNAi effect through adequate physicochemical properties, FR-α-mediated endocytosis, efficient endosomal escape, and siRNA delivery to cytoplasm with negligible cytotoxicity. Importantly, Fol-PαC (G4, DSC2.9, DSF2) improved the serum stability, blood circulating ability, and in vivo RNAi effects of siRNA, compared to Fol-PαC (G3). Furthermore, Fol-PαC (G4, DSC2.9, DSF2) complex with siRNA against Polo-like kinase 1 (siPLK1) suppressed the tumor growth compared to control siRNA complex. These results suggest that Fol-PαC (G4, DSC2.9, DSF2) has the potential as a novel tumor-targeting siRNA carrier in vitro and in vivo.

Abstract
Hyperbranched poly(amidoamine) (HPAMAM), structurally analogous to polyamidoamine dendrimer (PAMAM) dendrimers, has been suggested to be an effective carrier for gene delivery. In the present study, glutamic acid-modified hPAMAM was developed as a novel non-viral gene carrier for the first time. The hPAMAM was synthesized by using a modified one-pot method. DNA was found to be bound to hPAMAM at different weight ratios (WhPAMAM/WDNA). The resulting HPAMAM-Glu20 was able to efficiently protect the encapsulated-DNA against degradation for over 2 h. In addition to low cytotoxicity, the transfection efficiency of hPAMAM-Glu20 represented much higher (p < 0.05) than that of Lipofectamine 2000 in both MCF7 and MDA-MB231 cells. Cellular uptake of the hPAMAM-Glu20 in MDA-MB231 cells, 173.56 ± 1.37%, was significantly higher than that of MCF7 cells, 65.00 ± 1.73% (p < 0.05). The results indicated that hPAMAM-Glu20-mediated gene delivery to breast cancer cells is a feasible and effective strategy that may provide a new therapeutic avenue as a non-viral gene delivery carrier. In addition, it was found that hPAMAM-glutamic amino acid (Glu)-based gene delivery is an economical, effective and biocompatible method.

Abstract
In this review, we outline the concept and applicability of self-assembling dendrimers for gene-delivery applications. Low-molecular-weight, well-defined cationic dendritic arrays which have been modified with hydrophobic domains can form self-organized multivalent systems that have significant advantages over nonassembling, high-molecular-weight/polymeric gene vectors. Particular structural variations have been highlighted with respect to the individual components of the displayed dendritic amphiphiles, namely, the employed amine termini, the hydrophobic segment, the size of the dendritic array, and the integration of special features such as targeting ability and cleavability/degradability, which can all have a crucial effect on gene-transfection efficiencies. Accordingly, the scientific efforts to create new synthetic gene-delivery vectors to act as promising in vivo transfection agents in the future will be presented and discussed here.

Abstract
The widespread use of various cyclodextrin (CyD)-appended polymers and polyrotaxanes as gene carriers has been reported. Among the various polyamidoamine dendrimer (dendrimer) conjugates with CyDs (CDE), the dendrimer (G3) conjugate with α-CyD having an average degree of substitution (DS) of 2.4 (α-CDE (G3, DS 2)) displayed remarkable properties as DNA carriers. In an attempt to develop cell-specific gene transfer carriers, we prepared some sugar-appended α-CDEs, e.g. mannosylated, galactosylated, and lactosylated α-CDEs. In addition, PEGylated Lac-α-CDEs (G3) were prepared and evaluated as a hepatocyte-selective and serum-resistant gene transfer carrier. Moreover, PEGylated-α-CDE/CyD polypseudorotaxane systems for novel sustained DNA release system have been developed. Interestingly, glucronylglucosyl-β-cyclodextrin (GUG-β-CyD) conjugates with dendrimer (G2) (GUG-β-CDE (G2)) had superior gene transfer activity to α-CDE (G2), expecting a development of new series of sugar-appended CDEs over α-CDEs (G2). Collectively, sugar-appended α-CDEs have the potential as novel cell-specific and safe carriers for DNA.

Abstract
AIM Development and evaluation of a new targeted gene delivery system by first preforming self-assembled nanocomplexes from a polycationic amphiphilic cyclodextrin (paCD) and pDNA and then decorating the surface of the nanoparticles with folic acid (FA). EXPERIMENTAL SECTION The cyclodextrin derivative (T2) is a tetradecacationic structure incorporating 14 primary amino groups and 7 thioureido groups at the primary face of a cyclomaltoheptaose (β-CD) core and 14 hexanoyl chains at the secondary face. RESULTS AND CONCLUSIONS T2 complexed and protected pDNA (luciferase-encoding plasmid DNA, pCMVLuc) and efficiently mediated transfection in vitro and in vivo with no associated toxicity. The combination of folic acid with CDplexes afforded ternary nanocomplexes (Fol-CDplexes) that enhanced significantly the transfection activity of pCMVLuc in human cervix adenocarcinoma HeLa cells, especially when formulated with 1 μg FA/μg DNA. The observed transfection enhancement was associated to specific folate receptor (FR)-mediated internalization of Fol-CDplexes, as corroborated by employing a receptor-deficient cell line (HepG2) and an excess of free folic acid. The in vivo studies, including luciferase reporter gene expression and biodistribution, indicated that 24h after intravenous administration of the T2-pDNA nanocomplexes, transfection takes part mainly in the liver and partially in the lung. Interestingly, the corresponding Fol-CDplexes lead to an increase in the transfection activity in the lung and the liver compared to non-targeted CDplexes. Folate-CDplexes developed in this study have improved transfection efficiency and although various methods have been used for the preparation of ligand-DNA-complexes, covalent binding is usually needed and insoluble aggregates are formed unless the concentration of the components is minimized. However, the complexes developed by first time in this work were prepared by simple mixing. The synthetic nature of this formulation provides the potential of flexibility in terms of composition and the capability of inexpensive and large-scale production of the complexes. These nanovectors may be an adequate alternative to viral vectors for gene therapy in the future.

Abstract
Aim: In this study, a set of polycationic amphiphilic cyclodextrins featuring self-assembling capabilities in the presence of nucleic acids have been evaluated as therapeutic gene vectors for in vivo purposes. Materials & Methods: A tetradecacationic structure incorporating 14 primary amino groups and 7 thioureido groups in the primary face of the cyclooligosaccharide core and 14 hexanoyl chains in the secondary face was judged to be optimal for therapeutic gene delivery. Results & Conclusion: This compound efficiently mediated serum-resistant transfection in HeLa and HepG2 cells, comparing favorably with branched poly(ethyleneimine), with a low associated toxicity. Further transfection experiments using an encoding therapeutic gene plasmid (pCMVIL-12) were effected to report expression levels of IL-12. Finally, in vivo gene delivery experiments by systemic injection in mice indicated relatively high transfection levels in the liver, overcoming trapping of the nanoparticles in lung cells, with low toxicity.

Abstract
Polyamidoamine (PAMAM) dendrimers are highly branched spherical polymers that have emerged as potent synthetic drug and gene carriers; however, much remains to be learned about the mechanism of dendrimer-mediated cellular uptake. In this study, the endocytic pathway and intracellular trafficking of generation 4 (G4) PAMAM dendrimers were evaluated via fluorescein isothiocyanate (FITC) conjugation. We found that the G4-FITC dendrimers were internalized by energy-dependent and non-specific endocytic pathways. Interesting, G4-FITC dendrimers can not only buffer the endosomal/lysosomal pH but also co-localize with lysosomal markers over a period of 3 to 12 h, after which the signal decreased in the lysosomes and began to co-localize with the mitochondrial marker. This study contributes to the understanding of the molecular behaviour of G4 PAMAM dendrimers in a cellular environment and will facilitate the development of more effective PAMAM-mediated drug and gene delivery systems.

Abstract
The purpose of this study is to evaluate in vitro gene delivery mediated by asialofetuin-appended cationic liposomes (AF-liposomes) associating cyclodextrins (CyD/AF-liposomes) as a hepatocyte-selective nonviral vector. Of various CyDs, AF-liposomes associated with plasmid DNA (pDNA) and γ-cyclodextrin (γ-CyD) (pDNA/γ-CyD/AF-liposomes) showed the highest gene transfer activity in HepG2 cells without any significant cytotoxicity. In addition, γ-CyD enhanced the encapsulation ratio of pDNA with AF-liposomes, and also increased gene transfer activity as the entrapment ratio of pDNA into AF-liposomes was increased. γ-CyD stabilized the liposomal membrane of AF-liposomes and inhibited the release of calcein from AF-liposomes. The stabilizing effect of γ-CyD may be, at least in part, involved in the enhancing gene transfer activity of pDNA/γ-CyD/AF-liposomes. Therefore, these results suggest the potential use of γ-CyD for an enhancer of transfection efficiency of AF-liposomes.

Abstract
Cyclodextrin (CD) history has been largely dominated by their unique ability to form inclusion complexes with guests fitting in their hydrophobic cavity. Chemical funcionalization was soon recognized as a powerful mean for improving CD applications in a wide range of fields, including drug delivery, sensing or enzyme mimicking. However, 100 years after their discovery, CDs are still perceived as novel nanoobjects of undeveloped potential. This critical review provides an overview of different strategies to promote interactions between CD conjugates and genetic material by fully exploiting the inside-outside/upper-lower face anisotropy of the CD nanometric platform. Covalent modification, self-assembling and supramolecular ligation can be put forward with the ultimate goal to build artificial viruses for programmed and efficient gene therapy (222 references).

Abstract
Cyclodextrins (CDs) are a family of cyclic oligosaccharides that are composed of alpha-1,4-linked glucopyranose subunits. Cyclodextrins are produced from starch by enzymatic degradation. These macrocyclic carbohydrates with apolar internal cavities can form complexes with and solubilize many normally water-insoluble compounds. This review describes recent applications of CDs in pharmaceuticals with a major emphasis on drug delivery systems. The utility of these water-soluble cyclic glucans in a variety of foods, flavors cosmetics, packaging and textiles is elaborated. The role of these compounds in biocatalysis is also discussed. Cyclodextrins are used in separation science because they have been shown to discriminate between positional isomers, functional groups, homologues and enantiomers. This property makes them a useful agent for a wide variety of separations.

Abstract
In the past year, significant advances have been made in the synthesis and study of glycodendrimers and peptide dendrimers. Application of these dendrimers to the study of carbohydrate-protein and protein-protein interactions has facilitated the understanding of these processes. In addition, dendrimers show great promise as DNA- and drug-delivery systems.
