Abstract
Hearing loss is a significant disability that often goes under recognised, largely due to poor identification, prevention, and treatment. Steps are being made to amend these pitfalls in the investigation of hearing loss, however, the development of a cure to reverse advanced forms remains distant. This review details some current advances in the treatment of hearing loss, with a particular focus on genetic-based nanotechnology and how it may provide a useful avenue for further research. This review presents a broad background on the pathophysiology of hearing loss and some current interventions. We also highlight some potential genes that may be useful in the amelioration of hearing loss. Pathways of cellular differentiation from stem or supporting cell to functional hair cell are covered in detail, as this mechanism represents a key means of regenerating these cell types. Overall, we believe that polymer-based nanotechnology coupled with novel excipients represents a useful area of further research in the treatment of hearing loss, although further studies in this area are required.

Abstract
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), also known as APO2L, has emerged as a highly potential anticancer agent because of its capacity to effectively trigger apoptosis in tumor cells by specifically binding to either of its death receptors (DR4 or DR5) while having no adverse effects on normal cells. Nevertheless, its practical use has been hindered by its inefficient pharmacokinetics characteristics, the challenges involved in its administration and delivery to targeted cells, and the resistance exhibited by most cancer cells towards TRAIL. Gene therapy, as a promising approach would be able to potentially circumvent TRAIL-based cancer therapy challenges mainly through localized TRAIL expression and generating a bystander impact. Among different strategies, using nanoparticles in TRAIL gene delivery allows for precise targeting, and overcoming TRAIL resistance by combination therapy. In this review, we go over potential mechanisms by which cancer cells achieve resistance to TRAIL and provide an overview of different carriers for delivering of the TRAIL gene to resistant cancer cells, focusing on different types of nanoparticles utilized in this context. We will also explore the challenges, and investigate future perspectives of this nanomedicine approach for cancer therapy.

Abstract
Disorders of the central nervous system (CNS) which include a wide range of neurodegenerative and neurological conditions have become a serious global issue. The presence of CNS barriers poses a significant challenge to the progress of designing effective therapeutic delivery systems, limiting the effectiveness of drugs, genes, and other therapeutic agents. Natural nanocarriers present in biological systems have inspired researchers to design unique delivery systems through biomimicry. As natural resource derived delivery systems are more biocompatible, current research has been focused on the development of delivery systems inspired by bacteria, viruses, fungi, and mammalian cells. Despite their structural potential and extensive physiological function, making them an excellent choice for biomaterial engineering, the delivery of nucleic acids remains challenging due to their instability in biological systems. Similarly, the efficient delivery of genetic material within the tissues of interest remains a hurdle due to a lack of selectivity and targeting ability. Considering that gene therapies are the holy grail for intervention in diseases, including neurodegenerative disorders such as Alzheimer's disease, Parkinson's Disease, and Huntington's disease, this review centers around recent advances in bioinspired approaches to gene delivery for the prevention of CNS disorders.

Abstract
The strategic integration of multi-functionalities within a singular nanoplatform has received growing attention for enhancing treatment efficacy, particularly in chemo-photothermal therapy. This study introduces a comprehensive concept of Janus nanoparticles (JNPs) composed of Au and Fe3O4 nanostructures intricately bonded with β-cyclodextrins (β-CD) to encapsulate 5-Fluorouracil (5-FU) and Ibuprofen (IBU). This strategic structure is engineered to exploit the synergistic effects of chemo-photothermal therapy, underscored by their exceptional biocompatibility and photothermal conversion efficiency (∼32.88 %). Furthermore, these β-CD-conjugated JNPs enhance photodynamic therapy by generating singlet oxygen (1O2) species, offering a multi-modality approach to cancer eradication. Computer simulation results were in good agreement with in vitro and in vivo assays. Through these studies, we were able to prove the improved tumor ablation ability of the drug-loaded β-CD-conjugated JNPs, without inducing adverse effects in tumor-bearing nude mice. The findings underscore a formidable tumor ablation potency of β-CD-conjugated Au-Fe3O4 JNPs, heralding a new era in achieving nuanced, highly effective, and side-effect-free cancer treatment modalities. STATEMENT OF SIGNIFICANCE: The emergence of multifunctional nanoparticles marks a pivotal stride in cancer therapy research. This investigation unveils Janus nanoparticles (JNPs) amalgamating gold (Au), iron oxide (Fe3O4), and β-cyclodextrins (β-CD), encapsulating 5-Fluorouracil (5-FU) and Ibuprofen (IBU) for synergistic chemo-photothermal therapy. Demonstrating both biocompatibility and potent photothermal properties (∼32.88 %), these JNPs present a promising avenue for cancer treatment. Noteworthy is their heightened photodynamic efficiency and remarkable tumor ablation capabilities observed in vitro and in vivo, devoid of adverse effects. Furthermore, computational simulations validate their interactions with cancer cells, bolstering their utility as an emerging therapeutic modality. This endeavor pioneers a secure and efficacious strategy for cancer therapy, underscoring the significance of β-CD-conjugated Au-Fe3O4 JNPs as innovative nanoplatforms with profound implications for the advancement of cancer therapy.

Abstract
Multicomponent nanoparticle systems are known for their varied properties and functions, and have shown potential as gene nanocarriers. This study aims to synthesize and characterize ternary nickel-cobalt-ferrite (NiCoFe2O4) nanoparticles with the potential to serve as gene nanocarriers for cancer/gene therapy. The biogenic nanocarriers were prepared using a simple and eco-friendly method following green chemistry principles. The physicochemical properties of the nanoparticles were analyzed by X-ray diffraction, vibrating sample magnetometer, X-ray photoelectron spectroscopy, and Brunauer-Emmett-Teller. To evaluate the morphology of the nanoparticles, the field emission scanning electron microscopy with energy dispersive X-Ray spectroscopy, high-resolution transmission electron microscopy imaging, and electron tomography were conducted. Results indicate the nanoparticles have a nanoflower morphology with a mesoporous nature and a cubic spinel structure, where the rod and spherical nanoparticles became rose-like with a specific orientation. These nanoparticles were found to have minimal toxicity in human embryonic kidney 293 (HEK-293 T) cells at concentrations of 1 to 250 µg·mL-1. We also demonstrated that the nanoparticles could be used as gene nanocarriers for delivering genes to HEK-293 T cells using an external magnetic field, with optimal transfection efficiency achieved at an N/P ratio of 2.5. The study suggests that biogenic multicomponent nanocarriers show potential for safe and efficient gene delivery in cancer/gene therapy.

Abstract
Hearing loss impacts a large proportion of the global population. Damage to the inner ear, in particular the sensitive hair cells, can impact individuals for the rest of their lives. There are very limited options for interventions after damage to these cells has occurred. Targeted gene delivery may provide an effective means to trigger appropriate differentiation of progenitor cells for effective replacement of these sensitive hair cells. There are several hurdles that need to be overcome to effectively deliver these genes. Nanoencapsulation technology has previously been used for the delivery of pharmaceuticals, proteins and nucleic acids, and may provide an effective means of delivering genes to trigger appropriate differentiation. This review investigates the background of hearing loss, current advancements and pitfalls of gene delivery, and how nanoencapsulation may be useful.

Abstract
Chimeric antigen receptor (CAR) T cell therapy has recently shown unprecedented clinical efficacy for cancer treatment, particularly of hematological malignancies. However, the complex manufacturing processes that involve ex vivo genetic modification of autologous T cells limits its therapeutic application. CAR T cells generated in vivo provide a valid alternative immunotherapy, "off-the-shelf", for cancer treatment. This approach requires carriers for the delivery of CAR-encoding constructs, which are plasmid DNA or messenger RNA, to T cells for CAR expression to help eradicate the tumor. As such, there are a growing number of studies reporting gene delivery systems for in vivo CAR T cell therapy based on viral vectors and polymeric nanoparticles. Hyaluronic acid (HA) is a natural biopolymer that can serve for gene delivery, because of its inherent properties of cell recognition and internalization, as well as its biodegradability, biocompatibility, and presence of functional groups for the chemical conjugation of targeting ligands. In this review, the potential of HA in the delivery of CAR constructs is discussed on the basis of previous experience of HA-based nanoparticles for gene therapy. Furthermore, current studies on CAR carriers for in vivo-generated CAR T cells are included, giving an idea of a rational design of HA-based systems for the more efficient delivery of CAR to circulating T cells.

Abstract
Abnormal expression of microRNAs (miRNAs), which are highlyconserved noncoding RNAs that regulate the expression of various genes post transcriptionally to control cellular functions, has been associated with the development of many diseases. In some cases, disease-promoting miRNAs are upregulated, while in other instances disease-suppressive miRNAs are downregulated. To alleviate this imbalanced miRNA expression, either antagomiRs or miRNA mimics can be delivered to cells to inhibit or promote miRNA expression, respectively. Unfortunately, the clinical translation of bare antagomiRs and miRNA mimics has been challenging because nucleic acids are susceptible to nuclease degradation, display unfavorable pharmacokinetics, and cannot passively enter cells. This review emphasizes the challenges associated with miRNA mimic delivery and then discusses the design and implementation of polymer nanocarriers to overcome these challenges. Preclinical efforts are summarized, and a forward-looking perspective on the future clinical translation of polymer nanomaterials as miRNA delivery vehicles is provided.

Abstract
Nanoparticles (NPs) can be used to locally deliver anti-restenosis drugs when they are infused directly to the injured arteries after intervention procedures such as angioplasty. However, the efficacy of transferring NPs via infusion to the arterial wall is limited, at least partially, due to poor NP retention on the inner artery wall. To improve NP retention, angioplasty balloons coated with drug-loaded NPs were fabricated via either layer-by-layer (LbL) electrostatic coating or acrylic-based hydrogel (AAH) coating techniques. Three types of NPs, namely poly (lactide-co-glycolide) (PLGA), biodegradable photo-luminescent PLGA and urethane doped polyester were studied. The transfer efficacy of NPs from various coatings to the arterial wall were further evaluated to find the optimal coating conditions. The ex vivo NP transfer studies showed significantly more NPs being transferred to the rat arterial wall after the angioplasty procedure by the AAH coating (95% transfer efficiency) compared to that of the LbL technique (60%) and dip coating (20%) under flow conditions (10 dyn/cm2). Our results suggest that the AAH coating of drug-loaded NPs on the angioplasty balloon could potentially provide superior retention of drug-loaded NPs onto the arterial wall for a better local delivery of drug-loaded NPs to effectively treat arterial diseases.

Abstract
Steroidogenic acute regulatory protein (StAR) is responsible for the relocation of cholesterol across mitochondrial membrane in vertebrates and is, therefore, a key factor in regulating the rate and timing of steroidogenesis. In the present study, we developed chitosan nanoparticle (CNP) conjugated StAR gene construct (CNP-pcDNA4-StAR) in a eukaryotic expression vector, pcDNA4/HisMax A. CNPs of 135.4nm diameter, 26.7mV zeta potential and 0.381 polydispersity index were used for conjugation. The loading efficiency (LE) of pcDNA4-StAR construct with CNPs was found to be 86%. After the 24h of intramuscular injection, the CNP-pcDNA4-StAR plasmid could be detected from testis, brain, kidney and muscle tissues of Clarias batrachus. The transcript levels of important reproductive genes viz. cyp11a1, cyp17a1, 3β-hsd, 17β-hsd and cyp19a1 in CNP-pcDNA4-StAR treated group were initially low up to 24h, but significantly increased subsequently up to 120h. In naked pcDNA4-StAR treated group, the mRNA level of 3β-hsd, 17β-hsd and cyp19a1 increased initially up to 24h, while cyp11a1 and cyp17a1 increased up to 48h and then started declining. Similar results were obtained for 11-Ketotestosterone and 17β-estradiol. The results indicate relatively long lasting effects of nano-conjugated construct compared to the construct alone. Furthermore, the histopathology of gonads and liver authenticates its possible role in the gonadal development in fish without any adverse effect.

Abstract
Poly(2-hydroxypropylene imine)s containing segments of cystamine (PHPI-CA) are synthesized by polycondensation of 1,3-dibromo-2-propanol with a mixture of 1,3-diamino-2-propanol and cystamine. High molecular weight fractions of these polymers are collected by ultrafiltration and characterized by chemical analysis, 1 H and 13 C-NMR spectroscopy, size-exclusion chromatography with triple detection, and potentiometric titration, and are tested for DNA delivery in vitro. It is shown that PHPI-CA are highly branched polymers containing disulfide linkages. Transfection efficiency of PHPI-CA for DNA gives similar results to that of PHPI with GFP+ cell percent reaching 80-90%. Cytotoxicity levels for PHPI-CA are lower than that of PHPI. Novel polymers containing different amounts of disulfide linkages are able to disintegrate and release DNA following the treatment with reducing agent 1,4-dithiothreitol. Downstream application of PHPI-CA transfected cells for RNA purification shows that RNA yield is not affected even after the double transfection suggesting that these polymers could be great candidates for in vitro and in vivo transfection.

Abstract
Using single-molecule fluorescence microscopy and particle-tracking techniques, we elucidate the role DNA topology plays in the diffusion and conformational dynamics of crowded DNA molecules. We focus on large (115 kbp), double-stranded ring and linear DNA crowded by varying concentrations (0-40%) of dextran (10, 500 kDa) that mimic cellular conditions. By tracking the center-of-mass and measuring the lengths of the major and minor axes of single DNA molecules, we characterize both DNA mobility reduction as well as crowding-induced conformational changes (from random spherical coils). We reveal novel topology-dependent conformations, with single ring molecules undergoing compaction to ordered spherical configurations ∼20% smaller than dilute random coils, while linear DNA elongates by ∼2-fold. Surprisingly, these highly different conformations result in nearly identical exponential mobility reduction dependent solely on crowder volume fraction Φ, revealing a universal critical crowding concentration of Φc≅ 2.3. Beyond Φc DNA exhibits topology-independent conformational relaxation dynamics despite highly distinct topology-driven conformations. Our collective results reveal that topology-dependent conformational changes, unique to crowded environments, enable DNA to overcome the classically expected mobility reduction that high-viscosity crowded environments impose. Such coupled universal dynamics suggest a mechanism for DNA to maintain sufficient mobility required for wide-ranging biological processes despite severe cellular crowding.

Abstract
Induction of local (pulmonary) immunity plays a critical role in preventing dissemination of Mycobacterium tuberculosis (M. tb) during the early infection stage. To induce specific mucosal immunity, chitosan, a natural cationic polysaccharide, was employed as a mucosal gene carrier and complexed with pHSP65pep, our previously constructed multi-epitope gene vaccine, which induces splenic gamma-interferon (IFN-γ)(+) T helper cell 1 responses. The resultant chitosan-pHSP65pep was administered intranasally to BALB/c mice with four doses of 50 μg DNA followed by mycobacterial challenge 4 weeks after the final immunization. It was found that the chitosan formulation significantly induced production of secretory immunoglobulin A (P < 0.05) as determined by measuring its concentrations in lung lavage fluid and enhanced pulmonary CD4(+) and CD8(+) IFN-γ(+) T cell responses (P < 0.001) compared with naked gene vaccine. Improved protection against Mycobacterium bovis bacillus Calmette-Guérin (BCG) challenge was consistently achieved by the chitosan-DNA formulation both as the vaccine alone or in a BCG prime-vaccine boost immunization scenario. Our study shows that mucosal delivery of gene vaccine in a chitosan formulation remarkably enhances specific SIgA concentrations and mucosal IFN-γ(+) T cell response, which correlated positively with immunological protection.

Abstract
Successful gene therapy asks for multifunctional vectors which can not only protect DNA from degradation but also transfer it into nuclear and subsequently express the loaded gene. Here we reported a novel multilayered delivery system constructed with DNA, protamine (Pro) and polyethylenimine (PEI) via lay-by-layer (LbL) technique, which posed multifunctions. DNA was previously condensed into a compact core with Pro which also contained nuclear localisation signals (NLS) domains for nuclear transfer. Then additional DNA was deposited as the first layer onto the cationic core via the electrostatic attraction which would increase the loading dose of DNA. At last, PEI was absorbed as the outmost layer to achieve the endosomal escape. Therefore a quaternary polyplexes which offered high loading of DNA, nuclear transfer ability and endosomal escape capability was constructed with the LbL technique. The obtained quaternary polyplexes showed positive surface charge, spherical morphology, a relatively narrow particle size distribution and strong DNA protection capability. Compared with commercially available PEI/DNA complexes, the novel multifuctional vector exhibited not only lower cytotoxicity (P<0.05) but also higher transfection efficiency in HepG2 and HeLa cells (P<0.05) in vitro test.

Abstract
In this study, the gene delivery properties of new hyperbranched poly(amido amine)s (PAAs) with disulfide linkages in the main chain were investigated in comparison with their linear analogs. Eight different bioreducible PAAs were prepared by Michael addition of N,N'-bisacryloylpiperazine (BP) with cystamine (CYST) or N,N'-dimethylcystamine (DMC) and of N,N'-cystaminebisacrylamide (CBA) with N,N'-ethylenediamine (EDA) or N,N'-dimethylethylenediamine (DMEDA). In order to study the effect of terminal groups on the transfection efficiency, each polymer was terminated with 4-aminobutanol (ABOL) or with 2-aminoethanol (ETA). The hyperbranched and the linear PAAs generally formed polyplexes with plasmid DNA with sizes around 200nm and positive zeta potentials ranging from +10 to +22mV at polymer/DNA weight ratios equal or higher than 3/1. Remarkably low or no cytotoxicity was observed for both hyperbranched and linear PAAs. Hyperbranched CBA-containing PAAs showed higher gene expression in DNA transfection tests with COS-7 cells than their linear analogs and up to two times higher than linear PEI that was used as the reference polymer. Transfection efficiencies of the branched PAAs were generally enhanced by the presence of serum, which is a promising property for future in vivo studies with these hyperbranched PAAs. In this study the ease of synthetic modification of both linear and hyperbranched poly(amido amide)s and the versatility of hyperbranched PAAs in regulating DNA transfection and cytotoxicity are demonstrated. The results show the large possibilities for this class of polymers to provide polymeric vectors with controllable properties for gene therapy applications.

Abstract
OBJECTIVES To deliver the efficacy and safety of Ch-GNPs (Chitosan gold nanoparticles) conjugated anti-inflammatory molecules peroxisome proliferator activated receptor gamma (PPARγ) on implant surface titanium (Ti) to reduce implant-induced inflammation. MATERIALS AND METHODS The Ch-GNPs were conjugated with the PPARγ cDNA through a coacervation process. Conjugation was cast over Ti surfaces by dipping, and cells were seeded on different sizes (6 × 6 × 0.1 cm and 1 × 1 × 0.1 cm; n = 3) of Ti surfaces. The size of Ch-GNPs and surface characterization of Ti was performed using UV-vis spectroscopy, TEM (Transmission electron microscopy) and EDX (energy-dispersive X-ray). The DNA conjugation and transfection capacity of Ch-GNPs were simultaneously confirmed by agarose gel electrophoresis, β-galactosidase staining, and immunoblotting. RESULTS The Ch-GNPs were well dispersed and spherical in shape, with average size around 10-20 nm. Ti surfaces coated with Ch-GNPs/LacZ, as transfection efficacy molecule, showed strong β-galactosidase staining in MC-3T3 E1 cells. Cells cultured on Ch-GNPs/PPARγ-coated Ti surfaces were able to inhibit implant-induced inflammation by simultaneously suppressing the expression of tumor necrosis factor- alpha (TNF-α), interleukin-1 beta (IL-1β), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and matrix metalloproteinase-2 (MMP-2). The inhibition mechanism of Ch-GNPs/PPARγ was due to inhibition of both reactive oxygen species (ROS) and nitric oxide (NO) secretion (n = 3; P < 0.05). In addition, Ch-GNPs/PPARγ was able to increase expression of bone morphogenetic protein (BMP-7) and runt-related transcription factor-2 (RUNX-2). Furthermore, alkaline phosphatase activity (ALP) was also increased than that in control (n = 3; P < 0.01). Whereas, expression of receptor activator of NF-κB ligand (RANKL) was decreased. CONCLUSIONS The novel gene delivery materials, like Ch-GNPs, can carry the PPARγ cDNA into the required areas of the implant surfaces, thus aiding to inhibit inflammation and promote osteoblast function. Thus, the PPARγ on implant surfaces may promote its clinical application on peri-implantitis or periodontitis like diseases.

Abstract
Polymeric micelles are ideal carriers for solubilization and targeting applications using hydrophobic drugs. Stability of colloidal aggregates upon injection into the bloodstream is mandatory to maintain the drugs' targeting potential and to influence pharmacokinetics. In this review we analyzed and discussed the most relevant stress mechanisms that polymeric micelles and related colloidal carriers encounter upon injection, including (1) dilution, (2) interactions with blood components, and (3) immunological responses of the body. In detail we analyzed the opsonin-dysopsonin hypothesis that points at a connection between a particles' protein-corona and its tissue accumulation by the enhanced permeability and retention (EPR) effect. In the established theory, size is seen as a necessary condition to reach nanoparticle accumulation in disease modified tissue. There is, however, mounting evidence of other sufficient conditions (e.g., particle charge, receptor recognition of proteins adsorbed onto particle surfaces) triggering nanoparticle extravasation by active mechanisms. In conclusion, the analyzed stress mechanisms are directly responsible for in vivo success or failure of the site-specific delivery with colloidal carrier systems.

Abstract
Poly(vinyl alcohol) (PVA) is commonly used as an emulsifier in the formulation of nanoparticles (NPs) comprising poly DL-lactide co-glycolide and polylactide-based biodegradable polymers for drug and gene delivery applications. A fraction of PVA remains associated with the NPs at the interface despite their repeated washing (residual PVA). We hypothesize that this residual PVA influences the interfacial properties of NPs and hence their biophysical interactions with membrane lipids. In this study, we formulated NPs using PVA of different molecular weights to determine the effects of the residual PVA on biophysical interactions of the formulated NPs with the endothelial cell model membrane using a Langmuir balance. Despite similar physical properties (particle size and zeta potential), NPs formulated with different PVA demonstrated significant variations in their intrinsic surface properties and biophysical interactions with the model membrane. This was evident from the difference in the surface pressure–area (π–A) isotherms prepared in the presence of different formulations of NPs and the change in surface pressure of the model membrane following interaction with NPs. The variation in the biophysical properties was observed even with the NPs formulated using the same molecular weight PVA but obtained from different lots. Since the interfacial properties of NPs can significantly influence NP interactions with cells and tissue, their biophysical characterization could prove to be an important parameter not only to obtain consistent results with NPs but also to optimize their properties for drug/gene delivery applications.

Abstract
Gene therapy based on delivery of viral and nonviral vectors has shown great promise for the treatment of human ocular diseases; however, limitations have consistently prevented its widespread clinical application. Viral vectors have generally been better in terms of efficiency but have safety concerns. Nonviral vectors, on the other hand, offer safety but have often been disappointing in terms of efficiency of nuclear delivery and gene expression. Extensive animal studies have reported significant progress using both systems, but thus far only a few studies have shown promise in human clinical trials. This article reviews both viral and nonviral work with focus on two candidates for clinical ocular application--AAV and nanoparticles. Of particular interest are various requirements for successful clinical application of these technologies including vector trafficking, delivery, specific gene expression, and treatment safety, and tolerance.

Gene transfer experiments have been developed during the last 2 decades and have been applied using in vitro, ex vivo and in vivo procedures. (i) In vitro methods have been applied to the uterine epithelial cells with the principal purpose of analysing some pathological change occurring in the uterus. In the male tract, epididymal cell lines have been used to evaluate the expression of particular genes and the function of specific proteins. (ii) Ex vivo methods have been applied to both the uterus and the vas deferens in humans, and good transgene expression has been recorded. (iii) In vivo gene transfer in the female tract has been employed in the uterus and oviduct using gene injections or electroporation methods. The glandular epithelium of both organs can be transfected efficiently, and transfection efficiency depends on the hormonal stage of the animal. The best expression occurred during pseudopregnancy and meta-estrus periods, when high progesterone and low estradiol concentrations occur. In the male tract, in vivo methods have been applied to mouse vas deferens and epididymis. In both organs, patches of epithelial regions appeared to express the transgenes. Furthermore, the secretions of both organs were also modified using gene constructions that led to the expression of some secretory proteins. In summary, gene modifications in the epithelium of the mammalian reproductive tract have been successful employing different technologies. Further improvements in transfection efficiency would help provide new insights into the physiology of these reproductive organs. Furthermore, the use of these methods could also be used to modify the fertility of mammals.

Abstract
The purpose of this research project was to develop nanoparticles with improved targeting, adhesion, and cellular uptake to activated or inflamed endothelial cells (ECs) under physiological flow conditions. Our hypothesis is that by mimicking platelet binding to activated ECs through the interaction between platelet glycoprotein Ibalpha (GP Ibalpha) and P-selectin on activated endothelial cells, GP Ibalpha-conjugated nanoparticles could exhibit increased targeting and higher cellular uptake in injured or activated endothelial cells under physiological flow conditions. To test this hypothesis, fluorescent-carboxylated polystyrene nanoparticles were selected for the study as a model particle because of its narrow size distribution as a "proof-of-concept." Using confocal microscopy, fluorescent measurements, and protein assays, cellular uptake properties were characterized for these polystyrene nanoparticles. The study also found that conjugation of 100-nm polystyrene nanoparticles with glycocalicin (the extracellular segment of GP Ibalpha) significantly increased the particle adhesion on P-selectin-coated surfaces and cellular uptake of nanoparticles by activated endothelial cells under physiological flow conditions. The results demonstrate that these novel endothelial-targeting nanoparticles could be the first step toward developing a targeted and sustained drug delivery system that can improve shear-regulated particle adhesion and cellular uptake.

Abstract
The endogenous angiotensin II (Ang II) type 2 receptor (AT 2) has been shown to mediate apoptosis in cardiovascular tissues. Thus, the aim of this study was to explore the anti-cancer effect of AT 2 over-expression on lung adenocarcinoma cells in vitro using adenoviral (Ad), FuGENE, and nanoparticle vectors. All three gene transfection methods efficiently transfected AT 2 cDNA into lung cancer cells but caused minimal gene transfection in normal lung epithelial cells. Ad-AT 2 significantly attenuated multiple human lung cancer cell growth (A549 and H358) as compared to the control viral vector, Ad-LacZ, when cell viability was examined by direct cell count. Examination of annexin V by flow cytometry revealed the activation of the apoptotic pathway via AT 2 over-expression. Western Blot analysis confirmed the activation of caspase-3. Similarly, poly (lactide-co-glycolic acid) (PLGA) biodegradable nanoparticles encapsulated AT 2 plasmid DNA were shown to be effectively taken up into the lung cancer cell. Nanoparticle-based AT 2 gene transfection markedly increased AT 2 expression and resultant cell death in A549 cells. These results indicate that AT 2 over-expression effectively attenuates growth of lung adenocarcinoma cells through intrinsic apoptosis. Our results also suggest that PLGA nanoparticles can be used as an efficient gene delivery vector for lung adenocarcinoma targeted therapy.

Abstract
Gene therapy is a powerful approach in the treatment of a wide range of both inherited and acquired diseases. Nonviral delivery systems have been proposed as safer alternatives to viral vectors because they avoid the inherent immunogenicity and production problems that are seen when viral systems are used. Many cationic polymers, including high-molecular-weight polyethylenimine (PEI) have been widely studied as gene-delivery carriers, both, in vitro and in vivo. However, interest has recently developed in degradable polymeric systems. The advantage of degradable polymer is its low in-vivo cytotoxicity, which is a result of its easy elimination from the cells and body. Degradable polymer also enhances transfection of DNA or small interfering RNA (siRNA) for efficient gene expression or silencing, respectively. This review paper summarizes and discusses the recent advances with degradable PEIs, such as cross-linked and grafted PEIs for DNA and siRNA delivery.

Abstract
Antisense therapy has been investigated extensively over the past two decades, either experimentally for gene functional research or clinically as therapeutic agents owing to the conceptual simplicity, ease of design and low cost. The concept of this therapeutic approach is promising because short antisense oligonucleotides (ASOs) can be delivered into target cells for specific hybridisation with target mRNA, resulting in the inhibition of the expression of pathogenic genes. However, the efficient delivery of the ASO molecules into target cells remains challenging; this bottleneck together with several other technical hurdles need to be overcome before this approach becomes effective and widely adopted. A variety of vectors such as lipids, polymers, peptides and nanoparticles have been explored. This review outlines the recent advances of the non-viral ASO delivery strategies. Several recent scientific studies, including authors' contributions, have been selected to highlight the technical aspects of ASO delivery.

Abstract
A wide variety of nanoparticles (NPs) that can deliver incorporated therapeutic materials such as compounds, proteins, genes and siRNAs to the human liver have been developed to treat liver-related diseases. This review describes NP-based drug and gene delivery systems such as liposomes (including lipoplex), polymer micelles, polymers (including polyplex) and viral vectors. It focuses upon the modification of these NPs to enhance liver specificity or delivery efficiency in vitro and in vivo. We discuss recent advances in drug and gene delivery systems specific to the human liver utilizing bio-nanocapsules comprising hepatitis B virus (HBV) envelope L protein, which has a pivotal role in HBV infection. These NP-based medicines may offer novel strategies for the treatment of liver-related diseases and contribute to the development of nanomedicines targeting other tissues.

Abstract
Intensive research efforts have been placed on the development of nanospheres for targeted drug delivery for treating a variety of diseases, including coronary restenosis, cancer, and inflammatory reactions. Although most of these drug-bearing spheres are delivered via intravenous administration, little is known about the effect of sphere physical characteristics on the responses of vascular and blood cells. To find the answer, this work was aimed to investigate the cellular uptake of nanosized (100 nm) and microsized hydrogel spheres (1 microm) made of poly(N-isopropylacrylamide) by vascular cells and phagocytes under various flow conditions in vitro. We found that the cellular uptake of nanospheres depended on incubation times and sphere concentrations as well as on the introduced shear stress levels of the medium. Measurements of the intracellular-released fluorescence and confocal fluorescence microscopy revealed that nanospheres were internalized by endothelial cells and smooth muscle cells more than microspheres, whereas microspheres were rapidly taken up by phagocytes, especially at high concentration. Our results strongly suggest that hydrogel nanospheres are more effective as an intravascular delivery system compared to microspheres in the terms of vascular cellular uptake and biocompatibility.

Abstract
Mouse cauda epididymis were in-vivo transfected using the lipid FuGENE 6 as gene vector. Two gene constructions were employed: the p-GeneGRIP which codifies for the Green Fluorescent Protein (GFP) and the pSEAP-control that expresses an alkaline phosphatase as a secretion. Transfection was detected by fluorescence and appeared in the nucleus and cytoplasm of epithelial cells. Transfection was observed in 39.70% of cells after 2 days and in 31.77% after 7 days, and then diminished progressively. Moreover, the presence of the transgene in the DNA isolated from treated epididymides was observed by polymerase chain reaction. GFP gene expression appeared in large areas of the cauda epididymis and it was observed exclusively in the cytoplasm of epithelial cells. GFP gene expression occurred during 2 weeks after gene injection and occupied 32.24, 29.98 and 22.37% of the area of the tubules when analyzed 2, 7 and 15 days after gene injection. The cauda was also analyzed in toto and showed similar results. The use of the pSEAP-control gene showed that cauda epididymis secretions can also be modified by the transfection procedure. A significant increase of alkaline phosphatase activity appeared in the epididymal fluids 7 days after gene injection. These results indicate that transfection procedures could be an important tool in the future to study epididymal physiology or to change the fertilizing ability of spermatozoa.

Abstract
Coxsackievirus B3 (CVB3) is a gastrointestinal virus causing myocarditis in human and mice. An ideal vaccine for CVB3-myocarditis requires both humoral and cellular immunity at systemic and mucosal compartments. We described here an enhancing strategy for chitosan-pVP1 vaccine by co-immunizing with lymphotactin (LTN) gene, a T cell-attractive-chemokine, encapsulated in chitosan particle to provide more protection against CVB3. Mice were intranasally co-immunized with 4 doses of chitosan-DNA vaccines separately encapsulating VP1 and LTN plasmids by 2 week-intervals and challenged with CVB3 4 weeks after the last immunization. Compared with chitosan-pVP1 alone, co-immunization with chitosan-pLTN significantly increased high-avidity-neutralizing antibody levels in serum and in intestinal mucosa, and promoted systemic and mucosal Th1 and CD8(+)CTL immune responses. Accordingly, enhanced resistance to CVB3-myocarditis was evidenced by reduced myocardial viral load, profound subsidence of myocarditis and increased survival rate. This strategy represents a promising platform for Th1 polarization and protection against mucosal infectious pathogens.

Abstract
RNA interference technology has been developed as a potential therapeutic agent for many indications, including cancer. Silencing a specific oncogene in tumor cells brings about cell death both in vitro and in vivo. However, there is a great need for powerful delivery strategies to enhance the therapeutic effect of small interfering RNA (siRNA). This review summarizes different signaling pathways inhibited by siRNA and the advantages of targeted siRNA as a delivery system.

Abstract
BACKGROUND & AIMS Expression of osteopontin correlates with tumor progression and metastasis. The mechanisms by which osteopontin promotes tumor cell survival remain unclear. Here we used short-hairpin RNA-mediated gene silencing to investigate the antitumor effects by osteopontin depletion in hepatocellular carcinoma (HCC). METHODS We applied polyethylenimine nanoparticles to deliver a short-hairpin RNA for depletion of osteopontin expression in HCC cells. Tumorigenicity and metastatic potentials of HCC cells were studied in vitro and in nude mice. Nuclear factor-kappaB (NF-kappaB) activation was analyzed by gel shift assay and luciferase analysis. The expressions of integrins were examined by real-time reverse-transcription polymerase chain reaction. Apoptosis was examined by terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling assay and mitochondrial membrane potential analysis. RESULTS Down-regulation of osteopontin inhibited HCC cell growth, anchorage-independent growth, adhesion with fibronectin and invasion through extracellular matrix in vitro, and suppressed tumorigenicity and lung metastasis in nude mice. Osteopontin silencing resulted in suppression of alphav, beta1, and beta3 integrin expressions, blockade of NF-kappaB activation, inhibition of Bcl-2/Bcl-xL and XIAP expressions, increase of Bax expression, and induction of a mitochondria-mediated apoptosis. Furthermore, down-regulation of osteopontin inhibited drug-induced NF-kappaB activation and sensitized HCC cells to chemotherapeutic agents in vitro, which led to complete regression of HCC xenografts in nude mice. CONCLUSIONS Osteopontin may facilitate tumorigenesis and metastasis through prevention of tumor cells from apoptosis. RNA interference-mediated depletion of osteopontin may be a promising strategy for the treatment of HCC by sensitizing the chemotherapeutic drugs.

Abstract
The goal of the present work was to develop a new synthetic nanosystem for gene delivery. For this purpose, we chose two polysaccharides, hyaluronic acid (HA) and chitosan (CS), as the main components of the nanocarrier. Nanoparticles with different hyaluronate:chitosan (HA:CS) mass ratios (0.5:1 and 1:1) and different polymer molecular weights (hyaluronate 170 (HA) or <10 kDa (HAO) and chitosan 125 (CS) or 10-12 (CSO) kDa) could be obtained using an ionic crosslinking method. These nanoparticles were loaded with pDNA and characterized for their size, zeta potential and pDNA association efficiency. Moreover, their toxicity and ability to transfect the model plasmid pEGFP-C1 were evaluated in the cell line HEK 293, as well as their intracellular fate. The results showed that HA:CS nanoparticles have a small size in the range of 110-230 nm, a positive zeta potential of +10 to +32 mV and a very high pDNA association efficiency of 87-99% (w/w). On the other hand, nanoparticles exhibited low cell toxicity and transfection levels up to 25% GFP expressing HEK 293 cells, lasting for the whole observation period of 10 days. We also provide basic information about the role of both polymers, HA and CS, and the effect of their molecular weight on the effectiveness of the resulting DNA nanocarrier, being the highest transfection levels observed with HAO:CSO 1:1 nanoparticles. In conclusion, HA:CS nanoparticles are promising carriers for gene delivery.

Abstract
Enveloped viruses and nanosized biomimetic particles for drug and gene delivery enter target cells mainly through receptor-mediated endocytosis. A few models have been presented to elucidate the mechanics of particle engulfment by the cell membrane, showing how size and surface chemico-physical properties favor or oppose internalization. In this work, the effect of particle nonsphericity is addressed considering elliptical cylindrical particles with aspect ratio Gamma. Using a continuum energetic approach, three different conditions have been identified: for sufficiently small Gamma, the particle is not even wrapped by the cell membrane; for sufficiently large Gamma, the particle is partially wrapped ("frustrated endocytosis"); and for intermediate values of Gamma, the particle is fully wrapped and eventually internalized. Given the pleomorphism of viruses and the broad spectrum of shapes for nanosized biomimetic particles, the results presented may be of interest to virologists, pharmacologists, toxicologists, and nanotechnologists.

Abstract
INTRODUCTIONBiodegradable nanoparticles (NPs) are colloidal particles with a gene of interest encapsulated inside a polymeric matrix. They are typically 100 nm in diameter, and are formulated using FDA-approved, biodegradable, biocompatible polymers such as poly(D,L-lactide-co-glycolide) (PLGA) or polylactide (PLA). The NPs are taken up by cells via an endocytic process, and the encapsulated plasmid DNA entrapped in NPs is protected from degradation by both extra- and intracellular nucleases. It is released slowly, sustaining gene delivery and gene expression. In contrast, higher but transient gene expression is observed with lipid- or polymer-based complexes where most of the delivered DNA is available quickly for transfection. Thus, unlike other nonviral gene delivery systems, NPs thus constitute a sustained gene expression vector. Sustained gene expression is advantageous, especially when the half-life of the expressed protein is very low or when chronic gene delivery is required for therapeutic efficacy. This protocol describes a method for nanoencapsulation of DNA and the subsequent use of NPs for transfection.

Abstract
In an effort to surface engineering of poly(D,L-lactic acid) (PDLLA), layer-by-layer (LbL) self-assembly of chitosan (Chi) and deoxyribonucleic acid (DNA) were employed to build up multilayered films. The formation of multilayers was monitored by using Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), water contact-angle measurement, and atomic force microscopy (AFM), respectively. A full coverage of Chi/DNA pair film was formed only after the fifth sequential deposition (PEI/(DNA/Chi)2), which was revealed by contact-angle measurement. Surface chemistry and topography of multilayered films were directly related to the corresponding outmost layer component. Discernable island-like structures on PEI/(DNA/Chi)5/DNA layered PDLLA film was observed. Lysozyme-mediated multilayer degradation and DNA-releasing measurement suggested that DNA was gradually released into the incubation medium over a period of up to 32 h. The approach presented here may be exploited to develop controlled administration of functional DNA constructs from the surfaces of biomedical materials and devices in situ.

Abstract
Novel cationic pentablock copolymers based on poly(2-diethylaminoethylmethacrylate) (PDEAEM) and Pluronic F127 were evaluated as non-viral gene delivery vectors from a physiochemical point of view for stability and transfection efficiency in complete growth media. A novel strategy was introduced to sterically stabilize the polyplexes of such Pluronic-based cationic polymers against aggregation with serum proteins. As cationic pentablock copolymers condense plasmid DNA into nanoplexes of 100-150 nm diameter, unmodified Pluronic added to the formulation self-assemble with the pentablock copolymers on the surface of polyplexes and shield the cationic PDEAEM chains of pentablock copolymers sterically with its long poly(ethyleneoxide) chains. These coated polyplexes formed colloidally stable dispersions of 150-250 nm diameter in serum-supplemented buffers. Cryo-TEM micrographs also showed that coating polyplexes with unmodified Pluronic reduced aggregation in serum proteins. Pentablock copolymers preserved the integrity of plasmid DNA condensed inside the polyplexes and provided efficient resistance to its degradation by nucleases. Though the total amount of DNA retained by ExGen 500 polyplexes after nuclease digestion was more than that retained by pentablock copolymers, the amount of plasmid retained in supercoiled form was not significantly different. Polyplexes coated with unmodified Pluronic provided efficient transfection in SKOV3 cells in complete growth media, comparable to that provided by ExGen 500 in terms of number of cells transfected, and one order less in terms of total transgene protein expressed. These sterically shielded polyplexes also exhibited much lower cytotoxicities than uncoated polyplexes of pentablock copolymers, and significantly lower than the cytotoxicity of ExGen 500 at relevant concentrations. This colloidally stable, versatile, multi-component gene delivery system also forms thermo-reversible injectable hydrogels like Pluronics at physiological temperatures that can be used for sustained delivery of polyplexes, and is promising for systemic applications.
