A glutathione-sensitive cationic polymer delivery of CRISPR-Cas9 RNA plasmid for targeting nasopharyngeal carcinoma gene therapy. Colloids Surf B Biointerfaces 2023; 223:113146. [PMID: 36696824 DOI: 10.1016/j.colsurfb.2023.113146] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Revised: 12/31/2022] [Accepted: 01/11/2023] [Indexed: 01/15/2023]
Abstract
CRISPR-Cas9 technology has been proven to be the most straightforward and accurate tool for gene therapy, but some limitations, such as the inefficient transfection or inability to precisely target, prevent the gene therapy from achieving the desired therapeutic effect. To overcome these, a kind of glutathione-sensitive cationic vectors, hyperbranched polyamide amine (HPAA) was designed for Delivery of CRISPR-Cas9 RNA plasmid, and the cyclic RGD (Arg-Gly-Asp) was conjugated for the targeted treatment of nasopharyngeal carcinoma (NPC). Disulfide bonds in HPAA segments can specifically respond to the high glutathione concentration in the tumor microenvironment. Meanwhile, RGD could especially interact to the integrin αvβ3 receptors which are highly expressed on the surface of NPC tumor cells. The results showed that more HPAA-RGD/SGK3-gRNA complexes could be uptaken by NPC HNE-1 cells after RGD was conjugated, and then the plasmid could be accumulated in the NPC tumor as well, which may assure the satisfied NPC therapy effect in vivo. In transfection assays, this complex showed the acceptable gene transfection efficiency in vitro and the obvious tumor inhibition effect in vivo, suggested a potential application in gene therapy to NPC.

Abstract
Intracellular bacterial infections pose a serious threat to public health. Macrophages are a heterogeneous population of immune cells that play a vital role in intracellular bacterial infection. However, bacteria that survive inside macrophages could subvert the cell signaling and eventually reduce the antimicrobial activity of macrophages. Herein, dual pH-responsive polymer (poly[(3-phenylprop-2-ene-1,1-diyl)bis(oxy)bis(enthane-2,1-diyl)diacrylate-co-N-aminoethylpiperazine] (PCA)) nanoparticles were developed to clear intracellular bacteria by activating macrophages and destructing bacterial walls. The presence of acid-labile acetal linkages and tertiary amine groups in the polymer's backbone endow hyperbranched PCA dual pH-response activity that shows acid-induced positive charge increase and cinnamaldehyde release properties. The biodegraded PCA nanoparticles could significantly inhibit the growth of bacteria by damaging the bacterial walls. Meanwhile, PCA nanoparticles could uptake by macrophages, generate reactive oxygen species (ROS), and remodel the immune response by upregulating M1 polarization, leading to the reinforced antimicrobial capacity. Furthermore, PCA nanoparticles could promote bacteria-infected wound healing in vivo. Therefore, these dual pH-responsive PCA nanoparticles enabling bacteria-killing and macrophage activation provide a novel outlook for treating intracellular infection.

Abstract
Hyperbranched polymers and multiarm star polymers are a type of dendritic polymers which have attracted substantial interest during the last 30 years because of their unique properties. They can be used to modify epoxy thermosets to increase their toughness and flexibility but without adversely affecting other properties such as reactivity or thermal properties. In addition, the final properties of materials can be tailored by modifying the structure, molecular weight, or type of functional end-groups of the hyperbranched and multiarm star polymers. In this review, we focus on the modification of epoxy-based thermosets with hyperbranched and multiarm star polymers in terms of the effect on the curing process of epoxy formulations, thermal, mechanical, and rheological properties, and their advantages in fire retardancy on the final thermosets.

Abstract
Biomaterials is an exciting and dynamic field, which uses a collection of diverse materials to achieve desired biological responses. While there is constant evolution and innovation in materials with time, biomaterials research has been hampered by the relatively long development period required. In recent years, driven by the need to accelerate materials development, the applications of machine learning in materials science has progressed in leaps and bounds. The combination of machine learning with high-throughput theoretical predictions and high-throughput experiments (HTE) has shifted the traditional Edisonian (trial and error) paradigm to a data-driven paradigm. In this review, each type of biomaterial and their key properties and use cases are systematically discussed, followed by how machine learning can be applied in the development and design process. The discussions are classified according to various types of materials used including polymers, metals, ceramics, and nanomaterials, and implants using additive manufacturing. Last, the current gaps and potential of machine learning to further aid biomaterials discovery and application are also discussed.

Abstract
Specifically amplifying the emission signals of optical probes in tumors is an effective way to improve the tumor-imaging sensitivity and contrast. In this paper, the first case of dendron-based fluorescence turn-on probes mediated by a Förster resonance energy transfer (FRET) mechanism is reported. Dendrons up to the fourth generation with a hydrophilic oligo(ethylene glycol) scaffold are synthesized by a solid-phase synthesis strategy, and show precise and defect-free chemical structures. To construct the fluorescence turn-on probe, one Cy5.5 molecule is conjugated to the focal of a G3 dendron through a robust linkage and eight Black Hole Quencher 3 (BHQ-3) molecules are conjugated to its periphery through a PEG chain bearing a reductively cleavable disulfide linkage. By in vitro and in vivo experiments, it is demonstrated that the fluorescence of the dendron-based probe can be activated effectively and rapidly in the reductive environments of tumor cells and tissues, and the probe thus exhibits amplified tumor signals and weak normal tissue signals. Compared with the reported nanoscale turn-on probes, the dendron-based probe has several significant advantages, such as well-defined chemical structure, precisely controllable fluorophore/quencher conjugation sites and ratio, desirable chemical stability, and reproducible pharmacokinetic and pharmacological profiles, and is very promising in tumor detection.

Abstract
BACKGROUND PEI is currently the most used non-viral gene carrier and the transfection efficiency is closely related to the molecular weight; however, the prominent problem is that the cytotoxicity increased with the molecular weight. METHODS A novel redox responsive biodegradable diselenide cross-linked polymer (dPSP) was designed to enhance gene expression. ICG-pEGFP-TRAIL/dPSP nanoparticles with high drug loading are prepared, which have redox sensitivity and plasmid protection. The transfection efficiency of dPSP nanoparticle was evaluated in vitro. RESULTS The plasmid was compressed by 100% at the N/P ratio of 16, and the particle size was less than 100 nm. When explored onto high concentrations of GSH/H2O2, dPSP4 degraded into small molecular weight cationic substances with low cytotoxicity rapidly. Singlet oxygen (1O2) was produced when indocyanine green (ICG) was irradiated by near-infrared laser irradiation (NIR) to promote oxidative degradation of dPSP4 nanoparticles. Under the stimulation of NIR 808 and redox agent, the particle size and PDI of ICG-pDNA/dPSP nanoparticle increased significantly. CONCLUSION Compared with gene therapy alone, co-transportation of dPSP4 nanoparticle with ICG and pEGFP-TRAIL had better antitumor effect. Diselenide-crosslinked polyspermine had a promising prospect on gene delivery and preparation of multifunctional anti-tumor carrier.

Abstract
Introduction: The delivery of nucleic acid therapeutics through non-viral carriers face multiple biological barriers that reduce their therapeutic efficiency. Despite great progress, there remains a significant technological gap that continues to limit clinical translation of these nanocarriers. A number of polymeric materials are being exploited to efficiently deliver nucleic acids and achieve therapeutic effects. Areas covered: We discuss the recent advances in the polymeric materials for the delivery of nucleic acid therapeutics. We examine the use of common polymer architectures and highlight the challenges that exist for their development from bench side to clinic. We also provide an overview of the most notable improvements made to circumvent such challenges, including structural modification and stimuli-responsive approaches, for safe and effective nucleic acid delivery. Expert opinion: It has become apparent that a universal carrier that follows 'one-size' fits all model cannot be expected for delivery of all nucleic acid therapeutics. Carriers need to be designed to exhibit sensitivity and specificity toward individual targets diseases/indications, and relevant subcellular compartments, each of which possess their own unique challenges. The ability to devise synthetic methods that control the molecular architecture enables the future development that allow for the construction of 'intelligent' designs.

Abstract
mRNA has broad potential as a therapeutic. Current clinical efforts are focused on vaccination, protein replacement therapies, and treatment of genetic diseases. The clinical translation of mRNA therapeutics has been made possible through advances in the design of mRNA manufacturing and intracellular delivery methods. However, broad application of mRNA is still limited by the need for improved delivery systems. In this review, we discuss the challenges for clinical translation of mRNA-based therapeutics, with an emphasis on recent advances in biomaterials and delivery strategies, and we present an overview of the applications of mRNA-based delivery for protein therapy, gene editing, and vaccination.

Abstract
Recently greater emphasis has been given to combination therapy for generating synergistic effects of treating cancer. Recent studies on thiol-sensitive nanocarriers for the delivery of drug or gene have shown promising results. In this review, we will examine the rationale and advantage in using nanocarriers for the combined delivery of different anticancer drugs and biologics. Here, we also discuss the role of nanocarriers, particularly redox-sensitive polymers in evading or inhibiting the efflux pump in cancer and how they modulate the sensitivity of cancer cells. The review aims to provide a good understanding of the new pattern of cancer treatment and key concerns for designing nanomedicine of synergistic combinations for cancer therapy.

Self-sensibilized polymeric prodrug co-delivering MMP-9 shRNA plasmid for combined treatment of tumors. Acta Biomater 2018; 69:277-289.

Abstract
Polymeric prodrugs are of immense interest as anticancer drug-delivery system owing to their superior drug stability during circulation and satisfactory drug loading capacity. However, they are usually less effective than free drugs due to imperfect degradable characteristics or active sites blockage. A polymeric prodrug (HPAA-MTX) with chemotherapeutic self-sensibilization effect consisting of glutathione (GSH)-triggered hyperbranched poly(amido amine) (HPAA) and methotrexate (MTX) was designed and synthesized in this work. This prodrug not only showed better inhibition effect on the tumor cells proliferation compared with free MTX, but also displayed selective sensibilization to tumor cells rather than normal cells. Meanwhile, HPAA-MTX was also explored as a MMP-9 shRNA plasmid delivery vector due to their rich amino group of HPAA, accompanying with MTX for simultaneous inhibiting tumor cells proliferation and migration. As expected, HPAA-MTX possessed excellent gene delivery capacity with significant down-regulation expression of MMP-9 protein and further inhibition of MCF-7 cells migration. Benefiting from the self-sensibilization effect and MTX/MMP-9 co-delivery strategy, this HPAA-MTX/MMP-9 co-delivery system exhibited significantly improved therapeutic efficacy to breast cancer in a combined manner which was confirmed through in vitro and in vivo assays. The strategy established in this study provided a facile "all-in-one" platform to integrate the drug/gene co-delivery strategy and self-sensibilization effect into one single nanocomposite for potential cancer treatment. STATEMENT OF SIGNIFICANCE A cationic polymeric prodrug with chemotherapeutic self-sensibilization effect was designed and showed better inhibition effect on tumor cells proliferation compared with its free drug, as well displayed the selective sensibilization effect to tumor cells rather than normal cells. Moreover, the prodrug could also deliver MMP-9 shRNA plasmid for a combined therapy. As expected, the prodrug possessed excellent gene delivery capacity with significant down-regulation expression of MMP-9 protein and further inhibition of MCF-7 cells migration. Benefiting from the self-sensibilization effect and the drug/gene co-delivery strategy, this prodrug exhibited significantly improved therapeutic efficacy to breast cancer in a combined manner.

Abstract
Intracellular delivery of protein therapeutics by cationic polymer vehicles is an emerging technique that is, however, encountering poor stability, high cytotoxicity and non-specific cell uptake. Herein, we present a facile strategy to optimize the protein-polycation complexes by encapsulating with linear-dendritic telodendrimers. The telodendrimers with well-defined structures enable the rational design and integration of multiple functionalities for efficient encapsulation of the protein-polycation complexes by multivalent and hybrid supramolecular interactions to produce sub-20 nm nanoparticles. This strategy not only reduces the polycation-associated cytotoxicity and hemolytic activity, but also eliminates the aggregation and non-specific binding of polycations to other biomacromolecules. Moreover, the telodendrimers dissociate readily from the complexes during the cellular uptake process, which restores the capability of polycations for intracellular protein delivery. This strategy overcomes the limitations of polycationic vectors for intracellular delivery of protein therapeutics.

Abstract
The physiological condition of the human body is a composite of different environments, each with its own parameters that may differ under normal, as well as diseased conditions. These environmental conditions include factors, such as pH, temperature and enzymes that are specific to a type of cell, tissue or organ or a pathological state, such as inflammation, cancer or infection. These conditions can act as specific triggers or stimuli for the efficient release of therapeutics at their destination by overcoming many physiological and biological barriers. The efficacy of conventional treatment modalities can be enhanced, side effects decreased and patient compliance improved by using stimuli-responsive material that respond to these triggers at the target site. These stimuli or triggers can be physical, chemical or biological and can be internal or external in nature. Many smart/intelligent stimuli-responsive therapeutic gene carriers have been developed that can respond to either internal stimuli, which may be normally present, overexpressed or present in decreased levels, owing to a disease, or to stimuli that are applied externally, such as magnetic fields. This review focuses on the effects of various internal stimuli, such as temperature, pH, redox potential, enzymes, osmotic activity and other biomolecules that are present in the body, on modulating gene expression by using stimuli-regulated smart polymeric carriers.

Abstract
CRISPR/Cas9 genome editing platforms are widely applied as powerful tools in basic research and potential therapeutics for genome regulation. The appropriate alternative of delivery system is critical if genome editing systems are to be effectively performed in the targeted cells or organisms. To date, the in vivo delivery of the Cas9 system remains challenging. Both physical methods and viral vectors are adopted in the delivery of the Cas9-based gene editing platform. However, physical methods are more applicable for in vitro delivery, while viral vectors are generally concerned with safety issues, limited packing capacities, and so on. With the robust development of nonviral drug delivery systems, lipid- or polymer-based nanocarriers might be potent vectors for the delivery of CRISPR/Cas9 systems. In this review, we look back at the delivery approaches that have been used for the delivery of the Cas9 system and outline the recent development of nonviral vectors that might be potential carriers for the genome editing platform in the future. The efforts in optimizing cationic nanocarriers with structural modification are described and promising nonviral vectors under clinical investigations are highlighted.

Abstract
Narrowly dispersed zwitterionic poly(amido amine) (PAA) nanogels with a diameter of approximately 100nm were prepared by a high-yielding and surfactant-free, inverse nanoprecipitation of PAA polymers. The resulting, negatively charged, nanogels (PAA-NG1) were functionalized with N,N-dimethylethylenediamine via EDC/NHS coupling chemistry. This resulted in nanogels with a positive surface charge (PAA-NG2). Both types of nanogels were fluorescently labelled via isothiocyanate coupling. PAA-NG1 displays high colloidal stability both in PBS and Fetal Bovine Serum solution. Moreover, both nanogels exhibit a distinct zwitterionic swelling profile in response to pH changes. Cellular uptake of FITC-labelled nanogels with RAW 264.7, PC-3 and COS-7 cells was evaluated by fluorescence microscopy. These studies showed that nanogel surface charge greatly influences nanogel-cell interactions. The PAA polymer and PAA-NG1 showed minimal cell toxicity as was evaluated by MTT assays. The findings reported here demonstrate that PAA nanogels possess interesting properties for future studies in both drug delivery and imaging. STATEMENT OF SIGNIFICANCE The use of polymeric nanoparticles in biomedical applications such as drug delivery and imaging, shows great potential for medical applications. However, these nanoparticles are often not stable in biological environments. Zwitterionic polymers have shown excellent biocompatibility, but these materials are not easily degradable in biological environments. With the aim of developing a nanoparticle for drug delivery and imaging we synthesized a biomimetic and readily biodegradable zwitterionic polymer, which was incorporated into nanogels. These nanogels showed excellent stability in the presence of serum and minimal cytotoxicity, which was tested in three cell lines. Because of their negative surface charge and excellent serum stability, these nanogels are therefore promising carriers for drug delivery and molecular imaging.

Abstract
For effective gene delivery to breast cancer MCF-7 cells, a folate-targeting redox gene carrier was synthesized by Michael addition polymerization between 1-(2-aminoethyl)piperazine and N,N'-cystaminebisacrylamide. Folate was then conjugated through an amidation reaction. The obtained folate-modified hyperbranched poly(amido amine)s (FA-PAAs) degraded in the presence of glutathione and displayed excellent transfection efficiency in vitro. In particular, FA-PAAs showed much higher gene delivery efficiency than PEI-25k in the presence of serum, leading to an obvious decrease in MMP-9 protein expression and the apoptosis of MCF-7 cells. Moreover, FA-PAAs displayed lower cytotoxicity and better blood compatibility than PEI-25k, suggesting a potential application in gene therapy for tumors.

Abstract
A surfactant-free emulsion-based approach is developed for preparation of nanogels. A water-in-oil emulsion is generated feasibly from a mixture of water and a solution of disulfide-containing hyperbranched PEGylated poly(amido amine)s, poly(BAC2-AMPD1)-PEG, in chloroform. The water droplets in the emulsion are stabilized and filled with poly(BAC2-AMPD1)-PEG, and the crosslinked poly(amido amine)s nanogels are formed via the intermolecular disulfide exchange reaction. FITC-dextran is loaded within the nanogels by dissolving the compound in water before emulsification. Transmission electron microscopy and dynamic light scattering are applied to characterize the emulsion and the nanogels. The effects of the homogenization rate and the ratio of water/polymer are investigated. Redox-induced degradation and FITC-dextran release profile of the nanogels are monitored, and the results show efficient loading and redox-responsive release of FITC-dextran. This is a promising approach for the preparation of nanogels for drug delivery, especially for neutral charged carbohydrate-based drugs.

Abstract
Bioreducible polymers have appeared as the ideal drug carriers for tumor therapy due to their properties of high stability in extracellular circulation and rapid drug release in intracellular reducing environment. Recently, the diselenide bond has emerged as a new reduction-sensitive linkage. In this work, the amphiphilic poly(ethylene glycol)-b-poly(L-lactide) containing diselenide bond has been synthesized and used to load anti-tumor drug, docetaxel (DTX), to form the redox micelles. It was found that the redox micelles showed a rapid response to glutataione (GSH), which resulted in a fast release of DTX in the presence of GSH. In contrast, <40 % of DTX was released from the micelles within 72 h under the normal condition (absence of GSH). The DTX-loaded redox micelles showed the significant inhibition effect to MCF-7 cells, and the cytotoxicity was dependent on the intracellular GSH concentrations. Moreover, considering the potentially clinical applications of the micelles through intravenous injection, the blood compatibility was also studied by the hemolysis analysis, activated partial thromboplastin time, prothrombin time and thromboelastography assays. These results confirmed that the redox micelles showed good blood safety, suggesting a potential application in tumor therapy.

Abstract
It was recently reported that ethanolamine-functionalized poly(glycidyl methacrylate) (PGEA) possesses great potential applications in gene therapy due to its good biocompatibility and high transfection efficiency. Importing responsivity into PGEA vectors would further improve their performances. Herein, a series of responsive star-shaped vectors, acetaled β-cyclodextrin-PGEAs (A-CD-PGEAs) consisting of a β-CD core and five PGEA arms linked by acid-labile acetal groups, were proposed and characterized as therapeutic pDNA vectors. The A-CD-PGEAs owned abundant hydroxyl groups to shield extra positive charges of A-CD-PGEAs/pDNA complexes, and the star structure could decrease charge density. The incorporation of acetal linkers endowed A-CD-PGEAs with pH responsivity and degradation. In weakly acidic endosome, the broken acetal linkers resulted in decomposition of A-CD-PGEAs and morphological transformation of A-CD-PGEAs/pDNA complexes, lowering cytotoxicity and accelerating release of pDNA. In comparison with control CD-PGEAs without acetal linkers, A-CD-PGEAs exhibited significantly better transfection performances.

Abstract
Conventional chemotherapy for the treatment of cancer has limited specificity when administered systemically and is often associated with toxicity issues. Enhanced accumulation of polymeric nanocarriers at a tumor site may be achieved by passive and active targeting. Incorporation of trigger responsiveness into these polymeric nanocarriers improves the anticancer efficacy of such systems by modulating the release of the drug according to the tumor environment. Triggers used for tumor targeting include internal triggers such as pH, redox and enzymes and external triggers such as temperature, magnetic field, ultrasound and light. While internal triggers are specific cues of the tumor microenvironment, external triggers are those which are applied externally to control the release. This review highlights the various strategies employed for the preparation of such trigger responsive polymeric nanocarriers for cancer therapy and provides an overview of the state of the art in this field.

Abstract
Vinyl-terminated hyperbranched poly(amido amine)s is obtained by Michael addition polymerization of 4-(aminomethyl)piperidine (AMPD) with a double molar N,N-cystaminebis(acrylamide) (BAC). Then an amphiphilic hyperbranched poly(BAC2-AMPD1)-PEG is produced via converting the vinyl groups to amines followed by PEGylation. Transmission electron microscopy (TEM), dynamic light scattering (DLS), and (1)H nuclear magnetic resonance (NMR) results indicate that the micelles can be obtained via self-assembly of hyperbranched poly(BAC2-AMPD1)-PEG. Further an anti-cancer drug, doxorubicin (DOX), can be loaded into the micelles. pH- and redox-response of the micelles of hyperbranched poly(BAC2-AMPD1)-PEG without and with DOX are investigated. The results of confocal microscopy and flow cytometry reflect that FITC tagged or DOX loaded micelles of hyperbranched poly(BAC2-AMPD1)-PEG can enter HepG2 and MCF-7 cells, and DOX can be observed in the nucleus of the cells. The cytotoxicity of the micelles without and with DOX is evaluated in HepG2 and MCF-7 cells, and the efficacy to kill the cancer cells is discussed in comparison with free DOX.

Abstract
The development of a versatile strategy to synthesize cationic nanocarriers capable of co-delivery and enhanced release of drugs and oligonucleotides is promising for synergic dual chemotherapy and gene therapy. Herein, we report a novel cationic amphiphilic diblock copolymer having a single reduction-responsive disulfide linkage at a junction between a FDA-approved polylactide (PLA) block and a cationic methacrylate block (C-ssABP). The amphiphilic design of the C-ssABP enables the formation of cationic micellar aggregates possessing hydrophobic PLA cores, encapsulating anticancer drugs; cationic coronas, ensuring complementary complexation with negatively-charged oligonucleotides through electrostatic interactions; and disulfides at interfaces, leading to enhanced release of both encapsulated drugs and complexed oligonucleotides. The reduction-responsive intracellular trafficking results from flow cytometry, confocal laser scanning microscopy, and cell viability, as well as in vitro gene transfection assay suggest that C-ssABP offers versatility as an effective nanocarrier platform for dual chemotherapy and gene therapy.
