Abstract
Cyclo-(D-Trp-Tyr) peptide nanotubes (PNTs) were reported to be potential carriers for oral gene delivery in our previous study; however, the effect of the aspect ratio (AR) of these PNTs on gene delivery in vivo could affect penetration or interception in biological environments. The aim of this study was to assess the feasibility of cyclo-(D-Trp-Tyr) PNTs with two ARs as carriers for oral pMBP-bcl-xL-hRluc delivery to the spinal cord to treat spinal cord injury (SCI). We evaluated the biodistribution of oligodendrocyte (OLG)-specific myelin basic protein gene promoter-driven antiapoptotic DNA (pMBP-bcl-xL) to the brain and spinal cord delivered with cyclo-(D-Trp-Tyr) PNTs with large (L) and small (S) PNTs with two ARs. After complex formation, the length, width, and AR of the L-PNTs/DNA were 77.86 ± 3.30, 6.51 ± 0.28, and 13.75 ± 7.29 μm, respectively, and the length and width of the S-PNTs/DNA were 1.17 ± 0.52 and 0.17 ± 0.05 μm, respectively, giving an AR of 7.12 ± 3.17 as detected by scanning electron microscopy. Each of these three parameters exhibited significant differences (p < 0.05) between L-PNTs/DNA and S-PNTs/DNA. However, there were no significant differences (p > 0.05) between the L-PNTs and S-PNTs for either their DNA encapsulation efficiency (29.72 ± 14.19 and 34.31 ± 16.78%, respectively) or loading efficiency (5.15 ± 2.58 and 5.95 ± 2.91%). The results of the in vitro analysis showed that the S-PNT/DNA complexes had a significantly higher DNA release rate and DNA permeation in the duodenum than the L-PNT/DNA complexes. Using Cy5 and TM-rhodamine to individually and chemically conjugate the PNTs with plasmid DNA, we observed, using laser confocal microscopy, that the PNTs and DNA colocalized in complexes. We further confirmed the complexation between DNA and the PNTs using fluorescence resonance energy transfer (FRET). Data from an in vivo imaging system (IVIS) showed that there was no significant difference (p > 0.05) in PNT distribution between L-PNTs/DNA and S-PNTs/DNA within 4 h. However, the S-PNT/DNA group had a significantly higher DNA distribution (p < 0.05) in several organs, including the ilium, heart, lungs, spleen, kidneys, testes, brain, and spinal cord. Finally, we determined the bcl-xL protein expression levels in the brain and spinal cord regions for the L-PNT/DNA and S-PNT/DNA complex formulations. These results suggested that either L-PNTs or S-PNTs may be used as potential carriers for oral gene delivery to treat SCI.

Abstract
The use of genetic material by non-viral transfer systems is still in its initial stages, but there are high expectations for the development of targeted therapies. However, nucleic acids cannot enter cells without help, they must be well protected to prevent degradation and overcome a variety of biological barriers, the endosomal barrier being one of the greatest cellular challenges. Herein, the structure-property-relationship was investigated in detail, using well-defined polymers. Polyacrylamides were synthesized via RAFT polymerization resulting in a polymer library of (i) different cationic groups as aminoethyl acrylamide (AEAm), dimethylaminoethyl acrylamide (DMAEAm), dimethylaminopropyl acrylamide (DMAPAm) and guanidinopropyl acrylamide (GPAm); (ii) different degree of polymerization; and investigated (iii) in different cell culture settings. The influence of molar mass and cationic moiety on complex formation with pDNA, cytotoxicity and transfection efficiency of the polymers were investigated. The systematic approach identified a pH-independent guanidinium-containing homopolymer (PGPAm89) as the polymer with the highest transfection efficiency and superior endosomal release under optimal conditions. Since PGPAm89 is not further protonated inside endosomes, common escape theories appear unsuitable. Therefore, the interaction with bis(monoacryloylglycerol)phosphate, a lipid specific for endosomal vesicles, was investigated. Our research suggests that the interactions between amines and lipids may be more relevant than anticipated.

Abstract
Gene transfection has broad applications in bioengineering and biomedical fields. Although many gene carrier materials and transfection methods have been developed, it remains unclear how cell morphology including cell spreading and elongation affects gene transfection. In this study, human bone marrow-derived mesenchymal stem cells (hMSCs) were cultured on micropatterns and transfected with cationic pAcGFP1-N1 plasmid complexes. The relationship between the cell morphology of hMSCs and gene transfection was investigated using micropatterning techniques. Spreading and elongation of hMSCs were precisely controlled by micropatterned surfaces. The results showed that well-spread and elongated hMSCs had high transfection efficiency. Analysis of the uptake of exogenous genes and DNA synthesis activity indicated that the well-spread and elongated cell morphology promoted gene transfection through enhanced uptake of the cationic complexes and accelerated DNA synthesis. The results should provide useful information for understanding of cell morphology on gene transfection and development of efficient gene transfection methods.

Abstract
Aim: To validate the efficacy of nanocomplexes from RGD-modified polyamidoamine (PAMAM G1) copolymer for prevention of restenosis. Materials & methods: Generation 1.0 polyamidoamine (PAMAM G1)-based copolymers (PGP) and RGD modified PGP (PGP-RGD) were synthesized and its properties were evaluated. Intravascular VEGF165 release tests were performed. Results: The PGP-RGD1 (2.6% grafting rate) exhibited lower cytotoxicity and larger combining ability with pDNA. The complexes had sizes of 80–160 nm and zeta potentials of 3–20 mV. Transfection efficiency of PGP-RGD1 complexes in human umbilical vein endothelial cells was larger than that of PGP complexes. Patency and expression level of artery in PGP-RGD1 group were higher than that in saline group. Conclusion: PGP-RGD1 will be a promising targeted gene vector.

Abstract
Polyethylenimine (PEI) has attracted much attention as a DNA condenser, but its toxicity and non-specific targeting limit its potential. To overcome these limitations, Antheraea pernyi silk fibroin (ASF), a natural protein rich in arginyl-glycyl-aspartic acid (RGD) peptides that contains negative surface charges in a neutral aqueous solution, was used to coat PEI/DNA complexes to form ASF/PEI/DNA ternary complexes. Coating these complexes with ASF caused fewer surface charges and greater size compared with the PEI/DNA complexes alone. In vitro transfection studies revealed that incorporation of ASF led to greater transfection efficiencies in both HEK (human embryonic kidney) 293 and HCT (human colorectal carcinoma) 116 cells, albeit with less electrostatic binding affinity for the cells. Moreover, the transfection efficiency in the HCT 116 cells was higher than that in the HEK 293 cells under the same conditions, which may be due to the target bonding affinity of the RGD peptides in ASF for integrins on the HCT 116 cell surface. This result indicated that the RGD binding affinity in ASF for integrins can enhance the specific targeting affinity to compensate for the reduction in electrostatic binding between ASF-coated PEI carriers and cells. Cell viability measurements showed higher cell viability after transfection of ASF/PEI/DNA ternary complexes than after transfection of PEI/DNA binary complexes alone. Lactate dehydrogenase (LDH) release studies further confirmed the improvement in the targeting effect of ASF/PEI/DNA ternary complexes to cells. These results suggest that ASF-coated PEI is a preferred transfection reagent and useful for improving both the transfection efficiency and cell viability of PEI-based nonviral vectors.
