Abstract
Combination therapy based on the co-delivery of therapeutic genes and anti-cancer drugs has emerged as a promising approach in the cancer treatment, and stimuli-responsive delivery systems could further improve the therapeutic efficacy. Herein, an ATP aptamer and its complementary DNA were used to form Duplex into which doxorubicin (DOX) was loaded to construct DOX-Duplex, and then the lipoic acid-modified oligoethyleneimine (LA-OEI) was employed as a carrier to realize the co-delivery of DOX-Duplex and miR-23b. The ternary nanocomplex LA-OEI/miR-23b/DOX-Duplex showed excellent anti-proliferative effect by inducing the cell apoptosis via mitochondrial signaling pathway and arresting the cell cycle at S phase. Meanwhile, the co-delivery of DOX-Duplex and miR-23b could efficiently inhibit the metastasis of cancer cells by reducing the expression level of MMP-9. The favorable anti-tumor efficacy of ternary nanocomplex was attributed to the rapid drug release in response to intracellular ATP concentration and reduction conditions and the synergistic effect between DOX-Duplex and miR-23b. Thus, ATP aptamer and reduction-responsive polymer provided a convenient platform to construct dual stimuli-responsive systems for the co-delivery of gene and drug in the cancer treatment.

Abstract
Recently, pH-sensitive polymers have received extensive attention in tumor therapy. However, the rapid response to pH changes is the key to achieving efficient treatment. Here, a novel shielding system with a rapidly pH-responsive polymer (PAMT) is synthesized by click reaction between poly(γ-allyl-l-glutamate) and thioglycolic acid or 2-(Boc-amino)ethanethiol. The zwitterionic biodegradable polymer PAMT, which is negatively charged at physiological pH, can be used to shield positively charged nanoparticles. PAMT is electrostatically attached to the surface of the positively charged PEI/pDNA complex to form a ternary complex. The zwitterionic PAMT-shielded complex exhibits rapid charge conversion when the pH decreases from 7.4 to 6.8. For the in vivo tumor inhibition experiment, PAMT/PEI/shVEGF injected intravenously shows a more significant inhibitory effect on tumor growth. The excellent results are mainly attributed to introduction of the zwitterionic copolymer PAMT, which can shield the positively charged PEI/shVEGF complex in physiological conditions, while the surface potential of the shielded complexes changes to a positive charge in the acidic tumor environment.

Abstract
In the past 10 years, with the increase of investment in clinical nano-gene therapy, there are many trials that have been discontinued due to poor efficacy and serious side effects. Therefore, it is particularly important to design a suitable gene delivery system. In this paper, we introduce the application of liposomes, polymers, and inorganics in gene delivery; also, different modifications with some stimuli-responsive systems can effectively improve the efficiency of gene delivery and reduce cytotoxicity and other side effects. Besides, the co-delivery of chemotherapy drugs with a drug tolerance-related gene or oncogene provides a better theoretical basis for clinical cancer gene therapy.

Abstract
Despite advances in cancer therapy, effective local treatment remains a formidable challenge due to the limit of efficient drug delivery method and the toxicity of chemotherapeutics. In the current study, a combined system was developed for simultaneous delivering doxorubicin (DOX) and cis-platinum (CDDP) to the lungs via pulmonary administration. Methoxy poly(ethylene glycol)-poly(ethylenimine)-poly(l-glutamate) (mPEG-OEI-PLG) copolymers were synthesized as a carrier for the co-delivery of DOX and CDDP. The co-delivery nanoparticles (Co-NPs) were formed with mPEG-OEI-PLG via electrostatic interactions for DOX loading and chelate interactions for CDDP loading, respectively. The results of in vitro cytotoxicity assays against B16F10 cell line showed that Co-NPs exhibited higher cytotoxicity than those treated with either DOX or CDDP alone. In the B16F10 tumor-bearing mice models, local delivery of Co-NPs by pulmonary administration demonstrated that Co-NPs had highly efficient accumulation in the lungs, especially in the tumor tissues of the lungs, but rarely in normal lung tissues. Moreover, Co-NPs exhibited higher anti-tumor efficiency for metastatic lung cancer than that in the single treatment of DOX or CDDP, while no obvious side effects were observed during the pulmonary treatment. The present pulmonary delivery by exploiting co-loaded nanoparticles was proved to be a promising drug delivery strategy for effective lung cancer therapy.

Abstract
Gene therapy has been a promising strategy for treating numerous gene-associated human diseases by altering specific gene expressions in pathological cells. Application of nonviral gene delivery is hindered by various dilemmas encountered in systemic gene therapy. Therefore, solutions must be established to address the unique requirements of gene-based treatment of diseases. This review will particularly highlight the dilemmas in polycation-based gene therapy by systemic treatment. Several promising strategies, which are expected to overcome these challenges, will be briefly reviewed. This review will also explore the development of polycation-based gene delivery systems for clinical applications.

Abstract
Due to the polyanionic nature of DNA, typically cationic or neutral delivery vehicles have been used for gene delivery. As a new approach, this study focuses on the design, development, and validation of nonviral polypeptide-based carriers for oligonucleotide delivery based on a negatively charged poly-l-glutamic acid (PGA) backbone partly derivatized with oligoaminoamide residues. To this end, PGA-derivatives modified with different pentameric succinyl tetraethylene pentamines (Stp5 ) are designed. Optionally, histidines for modulation of endosomal buffer capacity and cysteines for pDNA complex stabilization are included, followed by characterization of biophysical properties and gene transfer efficiency in N2a neuroblastoma or 4T1 breast cancer cells.

Abstract
As an option for genetic disease treatment and an alternative for traditional cancer chemotherapy, gene therapy achieves significant attention. Nucleic acid delivery, however, remains a main challenge in human gene therapy. Polymer-based delivery systems offer a safer and promising route for therapeutic gene delivery. Over the past five decades, various cationic polymers have been optimized for increasingly effective nucleic acid transfer. This resulted in a chemical evolution of cationic polymers from the first-generation polycations towards bioinspired multifunctional sequence-defined polymers and nanocomposites. With the increasing of knowledge in molecular biological processes and rapid progress of macromolecular chemistry, further improvement of polymeric nucleic acid delivery systems will provide effective tool for gene-based therapy in the near future.

Multi-armed poly(L-glutamic acid)-graft-polypropyleneinime as effective and serum resistant gene delivery vectors. Int J Pharm 2014; 465:444-54. [PMID: 24576809 DOI: 10.1016/j.ijpharm.2014.02.041] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2013] [Revised: 01/23/2014] [Accepted: 02/23/2014] [Indexed: 02/07/2023]
Abstract
A new series of multi-armed MP-g-PPI dendrimers were synthesized by polymerization of BLG-NCA using G2.0PPI as macromolecular initiator and subsequent aminolysis with G1.0PPI or G2.0PPI. The chemical structure and composition of the MP-g-PPI dendrimers were characterized by Fourier transform infrared spectroscopy (FT-IR) and nuclear magnetic resonance spectroscopy ((1)H NMR). The MP-g-PPI showed a great ability to combine with pDNA to form complexes, which protect the pDNA from nuclease degradation. Dynamic light scattering (DLS) measurement illustrated that the sizes of complexes were in range of 111-219 nm. The transmission electron microscope (TEM) and atomic force microscope (AFM) observation showed that the morphology of these complexes was spherical. The MTT assay demonstrated that cytotoxicity of the MP-g-PPI was lower than that of PEI 25K. The in vitro transfection test indicated that MP-g-PPI gene vectors displayed relative high transfection efficiency than that of PEI 25K and Lipofectamine 2000 in serum-containing medium. Furthermore, MP-g-PPI at the weight ratio of 7.5 displayed better serum-resistant capability than that of PEI 25K and Lipofectamine 2000. The above facts revealed that multi-armed MP-g-PPI dendrimers may be promising gene vectors with low cytotoxicity, high transfection efficiency and serum-resistant ability.

Abstract
To search for potential non-viral nucleic acids carriers, a series of novel cationic polymers, multi-armed poly(aspartate-graft-oligoethylenimine) (MP-g-OEI) copolymers were designed and synthesized by grafting different types of oligoethylenimine (OEI) to a multi-armed poly(l-aspartic acid) backbone. The as-synthesized MP-g-OEI copolymers were characterized by Fourier transform infrared spectroscopy, nuclear magnetic resonance and gel permeation chromatography. These MP-g-OEI copolymers (MP423, MP600 and MP1800) exhibited good capacity in condensing nucleic acids (pDNA or siRNA) into nanosized particles (90-150nm) with positive surface charges. Gene transfection activity of the MP-g-OEI copolymers (especially MP1800) showed improved performance compared with PEI25k in both HeLa and CHO cell lines. The silencing efficiency of MP600/siRNA and MP1800/siRNA complexes showed a superior knockdown effect in CT26 and Huh-7 cell lines. Moreover, the MP-g-OEI copolymers exhibited much lower cytotoxicity than PEI25k. Flow cytometric analysis showed that MP-g-OEI copolymers could efficiently mediate the entry of nucleic acids into cells. These results suggest that MP-g-OEI copolymers may be potential non-viral gene carriers for the delivery of nucleic acids in future gene therapy.

Abstract
Low transfection efficiency is always an issue when cationic polymers are used as a nonviral gene vector in the physiological condition, especially in the presence of proteins. A cationic magnetic nanoparticle (MNP) may be an alternative to solve this problem because a magnetic field can help to attract the MNP and internalize it into cells. The aim of this study was to determine the potency of polyethylenimine (PEI)-decorated MNPs for efficiently complexing and delivering plasmid DNA in vitro with the help of a magnetic field. PEI is associated with poly(acrylic acid)-bound superparamagnetic iron oxide (PAAIO) through electrostatic interactions (PEI-PAAIO). PEI-PAAIO formed stable polyplexes with pDNA in the presence and absence of 10% fetal bovine serum (FBS) and could be used for magnetofection. The effect of a static magnetic field on the cytotoxicity, cellular uptake, and transfection efficiency of PEI-PAAIO/pDNA was evaluated with and without 10% FBS. Magnetofection efficacy in HEK 293T cells and U87 cells containing 10% FBS was significantly improved in the presence of an external magnetic field. The amount of internalized iron was quantitatively measured using an inductively coupled plasma-optical emission spectrometer and directly visualized using Prussian blue staining. The internalized pDNA was visualized using a confocal laser scanning microscope.

Abstract
A novel pH-responsive poly(amino acid) grafted with oligocation was prepared through the combination of ring-opening polymerization (ROP) and subsequent atom transfer radical polymerization (ATRP). Firstly, poly(γ-2-chloroethyl-L-glutamate) (PCELG) with a pendent 2-chloroethyl group was synthesized through ROP of γ-2-chloroethyl-L-glutamate N-carboxyanhydride (CELG NCA) using n-hexylamine as the initiator. Then, PCELG was used to initiate the ARTP of 2-aminoethyl methacrylate hydrochloride (AMA), yielding poly(L-glutamate)-graft-oligo(2-aminoethyl methacrylate hydrochloride) (PLG-g-OAMA). The pK(a) of PLG-g-OAMA was 7.3 established by the acid-base titration method. The amphiphilic poly(amino acid) could directly self-assemble into a vesicle in PBS. The vesicle was characterized by TEM and DLS. Hydrophilic DOX·HCl was loaded into the hollow core of the vesicle. The in vitro release behavior of DOX·HCl from the vesicle in PBS could be adjusted by the solution pH. In vitro cell experiments revealed that the vesicle could reduce the toxicity of the DOX·HCl. In addition, the preliminary gel retardation assay displayed that PLG-g-OAMA could efficiently bind DNA at a PLG-g-OAMA/DNA weight ratio of 0.3 or above, indicating its potential use as a gene carrier. More in-depth studies of the PLG-g-OAMA vesicle for drug and gene co-delivery in vitro and in vivo are in progress.

Abstract
A polypeptide-based double hydrophilic graft copolymer was synthesized by the sequential grafting of poly(N-isopropylacrylamide) (PNIPAM) and 2-hydroxyethyl methacrylate (HEMA) onto poly(l-glutamic acid) (PGA) backbone. The copolymers were sensitive to both temperature and pH. The phase transition and aggregation behaviors of the graft copolymers in aqueous solutions were investigated by the turbidity measurements and dynamic laser scattering (DLS). The light transmittance decrease of the copolymers at temperature above lower critical solution temperature (LCST) was remarkably weakened at pH around 6.5 due to the coil to α helix change of PGA chain induced by pH. The copolymers can self-assembly into micelles with PNIPAM cores in the aqueous solution at pH 8.0 and 60°C. Subsequently, polymerization of HEMA led to the facile preparation of crosslinked micelles, which were observed directly by transmission electron microscopy (TEM). The temperature controlled shrinkage behaviors of crosslinked micelles highly depended on the pH values of the solution. The crosslinked micelles aggregated at pH 5.0 due to the increased hydrophobic interactions among them induced by the protonation of PGA component. These crosslinked micelles have promising applications as intelligent drug delivery vehicles.

Abstract
Cationic polymers play an important role in gene delivery. To search for potential non-viral gene carriers, a series of biodegradable cationic polymers, poly(ethylene glycol)-block-poly(carbonates-graft-oligoethylenimine) [mPEG-b-P(MCC-g-OEI), PPO] copolymers, were synthesized by grafting different kinds of oligoethylenimine (OEI) to the same biodegradable backbone, a derivative of poly(ethylene glycol)-block-polycarbonates. The as-synthesized PPO copolymers were characterized by Fourier transform infrared spectroscopy, nuclear magnetic resonance spectroscopy, and gel permeation chromatography. Two of the as-synthesized PPO copolymers (PPO600 and PPO1800) could efficiently condense DNA into nanosized particles (100-140 nm) with positive surface charges when the PPO/DNA mass ratio is above 10:1. The cell toxicity and gene transfection evaluations show that PPO copolymers, especially PPO1800, which exhibits lower cytotoxicity and higher gene transfection efficiency than PEI25K in the absence and the presence of serum in the CHO and COS-7 cell lines, have great potential as non-viral gene carriers. The PPO1800 copolymer images obtained by confocal laser scanning microscopy prove that PPO copolymers could efficiently mediate the entry of plasmid DNA into cells. These results show that PPO copolymers may be potential non-viral gene carriers in future applications of gene therapy.
