Abstract
In recent years, manganese dioxide (MnO2) nanoparticles with unique physicochemical properties have been widely used in many biomedical fields, such as biosensors, contrast agents, tumor therapy, and drug delivery. From these applications, MnO2 nanoparticles have great clinical translation potential. However, by contrast, the in vitro and in vivo biosafety of MnO2 nanoparticles have been deeply and thoroughly clarified for the clinical translation, which hinders their clinical applications. In this work, we deeply investigated the blood safety of MnO2 nanoparticles by conducting a series of in vitro and in vivo experiments. These included the effects of MnO2 nanoparticles on morphology of red blood cells, activation of platelets, coagulation functions, and toxicity of key organs. The obtained results show that these effects displayed a concentration-dependent manner of MnO2 nanoparticles. Different safe concentration ranges could be found in the different experimental index. This study provides important guidance for the specific biomedical applications of MnO2 nanoparticles, greatly accelerating their laboratory development and clinical translation.

Abstract
Ovarian cancer is the fifth leading cause of cancer-related death in women in the United States. Because success in early screening is limited, and most patients with advanced disease develop resistance to multiple treatment modalities, the overall prognosis of ovarian cancer is poor. Despite the revolutionary role of surgery and chemotherapy in curing ovarian cancer, recurrence remains a major challenge in treatment. Thus, improving our understanding of the pathogenesis of ovarian cancer is essential for developing more effective treatments. In this review, we analyze the underlying molecular mechanisms leading to chemotherapy resistance. We discuss the clinical benefits and potential challenges of using nanocarrier-delivered small interfering RNA to treat chemotherapy-resistant ovarian cancer. We aim to elicit collaborative studies on nanocarrier-delivered small interfering RNA to improve the long-term survival rate and quality of life of patients with ovarian cancer. This article is categorized under: RNA Methods > RNA Nanotechnology Regulatory RNAs/RNAi/Riboswitches > RNAi: Mechanisms of Action.

Abstract
Superparamagnetic iron oxide nanoparticles (SPIONs) have been widely used and have attracted increased attention for their unique physicochemical properties, especially in biomedical sciences as contrast agents following intravenous administration. However, only few studies have systematically reported the blood compatibility of iron oxide nanoparticles with different physicochemical properties such as different sizes and surface ligands. Therefore, we selected three widely used organic ligands (polyacrylic acid, hyaluronic acid, and chitosan) with modified SPIONs at the same size of 5-6 nm, and polyacrylic acid-modified SPIONs with different sizes (5, 10, and 30 nm) at different concentrations to evaluate their haemocompatibility. Our results revealed that SPIONs modified with polyacrylic acid demonstrated size-dependent destruction of red blood cells and complement activation. Interestingly, 5 nm SPIONs prolonged blood clotting time as compared with 10 nm and 30 nm SPIONs in vitro. Compared with polyacrylic acid-modified SPIONs, hyaluronic acid- and chitosan-modified SPIONs least affected red blood cells, platelets, coagulation, and complement activation. Hence, hyaluronic acid- and chitosan-coated SPIONs are more suitable for nanomedicine applications than polyacrylic acid-coated SPIONs. Furthermore, the interaction between SPIONs and blood components strongly correlated with the administered concentration of nanoparticles. These results will provide some experimental information for safe-by-design SPIONs.

Abstract
Although PEGylated polyplexes for gene delivery are widespread, there is a need for an in-depth investigation of the role of the PEGylation degree on the delivery efficiency of the systems. For this, a low-toxicity series of polymers for gene delivery were designed via Michael addition of poly(ethylene glycol)methyl ether methacrylate (PEGMA) onto branched polyethylenimine PEI. The goal was to finely tune the PEGylation degree in order to determine the system offering the best compromise between low cytotoxicity and high transfection efficiency under both in vitro and in vivo conditions. From dynamic light scattering tests, zeta potential measurements and gel retardation assay, it was found that nanoparticle assembly of PEI-g-PEGMA and DNA exhibited stable complex formation when the PEGylation degree was below 2.9%. In addition, complexes formed from polymers with a PEGylation degree of at least 1.67% (from PEI-g-PEGMA-6 to PEI-g-PEGMA-18) all showed very low hemolysis activity. Transfection efficiencies of the prepared complexes were determined using the pEGFP-C3 vector and β-galactosidase. Complexes made of PEI-g-PEGMA-6 and PEI-g-PEGMA-10 at a polymer nitrogen/DNA phosphorus weight ratio (Wn/Wp) of 5 led to the best transfection efficiencies. Moreover, PEGylation ensured low cytotoxicity of the complexes in particular at high Wn/Wp ratios. In vivo tests in a mouse model confirmed the in vitro results obtained for PEI-g-PEGMA-6-based complexes, at all Wn/Wp ratios tested, but also showed that a high PEGylation degree (5.2% for PEI-g-PEGMA-18), though inefficient in vitro could still lead to successful delivery in vivo, due to a prolonged contact time between the complex and the cells, and to the change in the biological environment. Overall, provided a fine tuning of the grafting density of PEGMA onto PEI and the polymer nitrogen/DNA phosphorus weight ratio, our results prove that PEI-g-PEGMA polymers constitute an efficient platform for successful in vitro and in vivo gene delivery, and ensure low cytotoxicity and prolonged cell viability.

Abstract
For cancer gene therapy, a safe and high-efficient gene carrier is a must. To resolve the contradiction between gene transfection efficiency and cytotoxicity, many polymers with complex topological structures have been synthesized, although their synthesis processes and structure control are difficult as well as the high molecular weight also bring high cytotoxicity. We proposed an alternative strategy that uses supramolecular inclusion to construct the aggregate from the small molecules for gene delivery, and to further explore the relationship between the topological assembly structure and their ability to deliver gene. Herein, PEI-1.8k-conjugating β-CD through 6-hydroxyl (PEI-6-CD) and 2-hydroxyl (PEI-2-CD) have been synthesized respectively and then assembled with diferrocene (Fc)-ended polyethylene glycol (PEG-Fc). The obtained aggregates were then used to deliver MMP-9 shRNA plasmid for MCF-7 cancer therapy. It was found that the higher gene transfection efficiency can be obtained by selecting PEI-2-CD as the host and tuning the host/guest molar ratios. With the rational modulation of supramolecular architectures, the aggregate played the functions similar to macromolecules which exhibit higher transfection efficiency than PEI-25k, but show much lower cytotoxicity because of the nature of small/low molecules. In vitro and in vivo assays confirmed that the aggregate could deliver MMP-9 shRNA plasmid effectively into MCF-7 cells and then downregulate MMP-9 expression, which induced the significant MCF-7 cell apoptosis, as well inhibit MCF-7 tumor growth with low toxicity. The supramolecular aggregates maybe become a promising carrier for cancer gene therapy and also provided an alternative strategy for designing new gene carriers.

Abstract
Amphiphilic block copolymer methoxy polyethyleneglycol-polycaprolactone (mPEG-PCL) has attracted interest in the biomedical field, due to its water solubility and biodegradability. Nevertheless, the blood safety of mPEG-PCL copolymers has not been investigated in detail. Because mPEG-PCL copolymers introduced in vivo would inevitably interact with blood tissue, an investigation of possible interactions of mPEG-PCL with key blood components is crucial. We studied the effects of two mPEG-PCL copolymer solutions on blood coagulation, the morphology and lysis of human red blood cells (RBCs), the structure of plasma fibrinogen, complement activation, and platelet aggregation. We found that higher concentrations of the mPEG-PCL copolymers impaired blood clotting, and the copolymers had little impact on the morphology or lysis of RBCs. From the spectroscopy results, the copolymers affected the local microstructure of fibrinogen. The copolymers significantly activated the complement system in a concentration-dependent way. At higher concentrations, the copolymers impaired platelet aggregation, which may have been mediated by an inhibition of the arachidonic acid pathway. These findings provide important information that may be useful for the molecular design and biomedical applications of mPEG-PCL copolymers. © 2016 Wiley Periodicals, Inc.

Abstract
Complement activation plays an important role in innate immune defense by triggering formation of the membrane attack complex (MAC), which is a biomacromolecular assembly that exhibits membrane-lytic activity against foreign invaders including various pathogens and biomaterials. Understanding the details of MAC structure and function has been the subject of extensive work involving bulk liposome and erythrocyte assays. However, it is difficult to characterize the mechanism of action of MAC inhibitor drug candidates using the conventional assays. To address this issue, we employ a biomimetic supported lipid bilayer platform to investigate how two MAC inhibitors, vitronectin and clusterin, interfere with MAC assembly in a sequential addition format, as monitored by the quartz crystal microbalance-dissipation (QCM-D) technique. Two experimental strategies based on modular assembly were selected, precincubation of inhibitor and C5b-7 complex before addition to the lipid bilayer or initial addition of inhibitor followed by the C5b-7 complex. The findings indicate that vitronectin inhibits membrane association of C5b-7 via a direct interaction with C5b-7 and via competitive membrane association onto the supported lipid bilayer. On the other hand, clusterin directly interacts with C5b-7 such that C5b-7 is still able to bind to the lipid bilayer, and clusterin affects the subsequent binding of other complement proteins involved in the MAC assembly. Taken together, the findings in this study outline a biomimetic approach based on supported lipid bilayers to explore the interactions between complement proteins and inhibitors, thereby offering insight into MAC assembly and regulation.
