Abstract
Traumatic brain injury (TBI) activates the NF-κB pathway in microglia and astrocytes, which secrete pro-inflammatory cytokines that disrupt the blood-brain barrier (BBB). Curdlan derivatives are promising carriers for the delivery of siRNA drugs. Herein, we evaluated the glial cell specificity, siRNA delivery efficiency, and the subsequent phenotypic regulation of glial cells by the Curdlan derivatives in the TBI mouse model. Our in vitro and in vivo studies confirmed that the (1) pAVC4 or CuMAN polymer encapsulating siRNA were internalized by astrocytes and microglia in a receptor-dependent manner; (2) systemic administration of the pAVC4 or CuMAN polymer encapsulating siRNA resulted in significant gene silencing efficiency, altered the phenotypic polarization of glial cells, and regulated the secretion of inflammatory cytokines; (3) this lessened neuroinflammation, ameliorated BBB destruction, and improved vascular recovery. These data suggested that pAVC4 and CuMAN polymers are promising RNA delivery vehicles that can efficiently deliver siRNA to the target cells.

Abstract
Autoimmune hepatitis (AIH) is a severe immune-mediated inflammatory liver disease whose standard of care is immunosuppressive treatment with inevitable undesired outcomes. Macrophage is acknowledged to aggravate liver damage, providing a promising AIH therapeutic target. Accordingly, in this study, a kind of curdlan-decorated fullerene nanoparticle (Cur-F) is fabricated to alleviate immune-mediated hepatic injury for treating AIH via reducing macrophage infiltration in a concanavalin A (Con A)-induced AIH mouse model. After intravenous administration, Cur-F primarily distributes in liver tissues, efficiently eliminates the excessive reactive oxygen species, significantly attenuates oxidative stress, and subsequently suppresses the nuclear factor kappa-B-gene binding (NF-κB) signal pathway, resulting in the lowered production of pro-inflammatory cytokines and the balancing of the immune homeostasis with the prevention of macrophage infiltration in the liver. The regulation of hepatic inflammation contributes to inhibiting inflammatory cytokines-induced hepatocyte apoptosis, decreasing the serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) contents and thus ameliorating immune-mediated hepatic injury. Notably, there is no detectable toxicity to the body. Our findings may open up novel avenues for AIH based on curdlan and fullerene materials.

Abstract
Receptor-mediated endocytosis has been used for tissue targeted delivery of short interfering RNA (siRNA) drugs. Herein, we investigated adenosine receptor (AR) as a candidate for receptor-mediated siRNA internalization. We synthesized adenosine functionalized cationic curdlan derivatives (denote CuAMP polymers). One of these polymers, CuAMP4, efficiently delivered siRNA to breast cancer cells expressing high level of A2B receptor. The internalization of siRNA loaded CuAMP4 by cancer cells was inhibited by free AMP as well as endocytosis inhibitors. Moreover, knockdown of A2BR by siRNA, or pre-treatment of the cells with anti-A2BR antibody, strongly inhibited the cellular uptake of CuAMP4. Our findings confirmed that A2BR can be utilized for cell type specific siRNA delivery, and CuAMP4 NP may be a promising delivery system for cancer cell targeted delivery of therapeutic siRNAs.

Abstract
Cationic polysaccharides have shown excellent ability of nucleic acids delivery. However, cationic curdlan derivatives with high degree of amination cause damage to the cell membrane and induce considerable cytotoxicity, limiting their in vivo application. Herein, we synthesized PEGylated 6-amino-6-deoxy-curdlan derivatives containing cleavable disulfide bonds. The resulting polymers (denote 6AC-2S PEGx) not only showed high affinity to siRNA but also exhibited significantly decreased cytotoxicity and hemolysis effect, while showing remarkable in vitro transfection efficiency. In vivo study demonstrated that 6AC-2S PEG40, which had a lower LD50 value than that of 6AC-100, did not cause liver damage, as the i.v. injection of 6AC-2S PEG40 to mouse did not increase serum level of ALT/AST. Furthermore, tissue distribution results showed that 6AC-2S PEG40 successfully delivered siRNA to liver, lung and spleen. Collectively, our data confirmed that PEGylation can increase the biocompatibility of cationic curdlan derivatives, which is a promising carrier for nucleic acid therapeutics.

Abstract
While the promise of oligonucleotide therapeutics, such as (chemically modified) ASO (antisense oligonucleotides) and short interfering RNAs, is undisputed from their introduction onwards, their unfavorable pharmacokinetics and intrinsic capacity to mobilize innate immune responses, were limiting widespread clinical use. However, these major setbacks have been tackled by breakthroughs in chemistry, stability and delivery. When aiming an intervention hepatic targets, such as lipid and sugar metabolism, coagulation, not to mention cancer and virus infection, introduction of N-acetylgalactosamine aided targeting technology has advanced the field profoundly and by now a dozen of N-acetylgalactosamine therapeutics for these indications have been approved for clinical use or have progressed to clinical trial stage 2 to 3 testing. This technology, in combination with major advances in oligonucleotide stability allows safe and durable intervention in targets that were previously deemed undruggable, such as Lp(a) and PCSK9 (proprotein convertase subtilisin/kexin type 9), at high efficacy and specificity, often with as little as 2 doses per year. Their successful use even the most visionary would not have predicted 2 decades ago. Here, we will review the evolution of N-acetylgalactosamine technology. We shall outline their fundamental design principles and merits, and their application for the delivery of oligonucleotide therapeutics to the liver. Finally, we will discuss the perspectives of N-acetylgalactosamine technology and propose directions for future research in receptor targeted delivery of these gene medicines.

Abstract
Cutaneous melanoma is the most aggressive skin cancer with notorious drug resistance. Inhibition of immune checkpoint molecules is one of the most promising approaches for cancer therapy. Herein, we show that RNAi mediated silencing of STAT3 expression in the tumor tissue robustly inhibit tumor growth in B16F10 mouse model of melanoma. We designed a peptidomimetic-based lipid nanoparticles (LNPs) for the delivery of siRNA in mouse model of melanoma. When systemically administered, the novel formulation (denote DoCh) preferentially delivered siRNA to the tumor tissue. Remarkably, sequential intravenous injections of siRNA against STAT3 induced profound silencing of STAT3 expression in tumor tissue, which resulted in significant downregulation of PD-L1, leading to significant inhibition of tumor growth through inhibition of tumor immune checkpoint. Moreover, DoCh-mediated siRNA delivery did not show noticeable damage to the major organs. Collectively, our data demonstrated that DoCh LNP is a promising tumor-targeted siRNA delivery system.

Abstract
Cationic curdlan derivatives are a class of promising carriers for nucleic acid delivery including short interfering RNA (siRNA). While our previous studies demonstrated the siRNA delivery efficiency of aminated curdlan derivatives, the associated cytotoxicity issue remained unsolved. To investigate the effects of alkylation on the toxicity as well as the transfection efficiency, we conjugated short alkyl chains to 6-amino-6-deoxy-curdlan (6AC-100). The cytotoxicity of alkylated 6AC-100 derivatives (denote CuVa polymers) decreased with the increase of the degree of substitution (DS). CuVa3, with the highest DS, showed a 50% decreased cytotoxicity compared to 6AC-100 to 6AC-100 at a concentration of 140 μg/mL. The CuVa polymers readily complexed with siRNA to form nanoparticles, and induced significant knockdown of a disease related gene (STAT3) in mouse melanoma cell line B16. However, B16 cells transfected with siSTAT3 complexed to CuVa3 showed the highest phenotypic changes. These findings suggest that CuVa polymers have significantly enhanced biocompatibility and may be a promising delivery system for delivery of therapeutic siRNAs.

Abstract
Sugars containing cationic polymers are potential carriers for in vitro and in vivo nucleic acid delivery. Monosaccharides such as glucose and galactose have been chemically conjugated to various materials of synergistic poly-lysine dendrimer systems for efficient and biocompatible delivery of short interfering RNA (siRNA). The synergistic dendrimers, which contain lipid conjugated glucose terminalized lysine dendrimers, have significantly lower adverse impact on cells while maintaining efficient cellular entry. Moreover, the synergistic dendrimers complexed to siRNA induced RNA interference (RNAi) in the cells and profoundly knocked down green fluorescence protein (GFP) as well as the endogenously expressing disease related gene Plk1. The new synergic dendrimers may be promising system for biocompatible and efficient siRNA delivery.

Abstract
6-Amino-6-deoxy-curdlan is a promising nucleic acid carrier that efficiently delivers plasmid DNA as well as short interfering RNA (siRNA) to various cell lines. The highly reactive C6-NH2 groups of 6-amino-6-deoxy-curdlan prompt conjugation of various side groups including tissue-targeting ligands to enhance cell-type-specific nucleic acid delivery to specific cell lines. Herein, to test the primary-cell-targeting efficiency of the curdlan derivative, we chemically conjugated a macrophage-targeting ligand, mannose, to 6-amino-6-deoxy-curdlan. The resulting curdlan derivative (denoted CMI) readily complexed with siRNA and formed nanoparticles with a diameter of 50-80 nm. The CMI nanoparticles successfully delivered a dye-labeled siRNA to mouse peritoneal macrophages. The delivery efficiency was blocked by mannan, a natural ligand for a macrophage surface mannose receptor (CD206), but not by zymosan, a ligand for the dectin-1 receptor, which is also present on the surface of macrophages. Moreover, CMI nanoparticles were internalized by macrophages only at 37 °C, suggesting that the cellular uptake of CMI nanoparticles was energy-dependent. Furthermore, CMI nanoparticle efficiently delivered siRNA against tumor necrosis factor α (TNFα) to lipopolysaccharide-stimulated primary mouse peritoneal macrophages. In vivo experiments demonstrated that CMI nanoparticles successfully delivered siTNFα to mouse peritoneal macrophages, liver, and lung and induced significant knockdown of the TNFα expression at both messenger RNA and protein levels. Therefore, our design of CMI may be a promising siRNA carrier for targeting CD206-expressing primary cells such as macrophage and dendritic cells.

Abstract
Lack of biocompatible and effective delivery carriers is a significant shortcoming for siRNA-mediated cancer therapy. To overcome these limitations, selenium nanoparticles (SeNPs) have been proposed for siRNA transfection vehicles. In this study, we synthesized novel RGDfC peptide modified selenium nanoparticles (RGDfC-SeNPs) as a gene vehicle, which was expected to improve the tumor-targeted delivery activity. RGDfC-SeNPs were compacted with siRNAs (anti-Oct4) by electrostatic interaction, which was capable of protecting siRNA from degradation. RGDfC-SeNPs exhibited excellent ability to deliver siRNA into HepG2 cells. siRNA transfection assay showed that RGDfC-SeNPs presented a higher gene silencing efficacy than conventional lipofectamine 2000. The cytotoxicity of RGDfC-SeNPs/siRNA on normal cells was lower than that on tumor cells, indicating that RGDfC-SeNPs/siRNA exhibited selectivity between normal and cancer cells. Additionally, Oct4 knockdown mediated by the selenium nanoparticle transfection arrested HepG2 cells mainly at the G2/M phase and significantly induced HepG2 cell apoptosis. Western blotting results showed that RGDfC-SeNPs/siRNA might trigger Wnt/β-catenin signaling, and further activate a BCL-2 apoptosis-related signaling pathway to advance HepG2 cell apoptosis. In vivo biodistribution experiments indicated that RGDfC-SeNPs/siRNA nanoparticles were specifically targeted to the HepG2 tumors. Most importantly, RGDfC-SeNPs/siRNA inhibited tumor growth significantly and induced HepG2 cell apoptosis via silencing the Oct4 gene. In addition, the results of H&E staining demonstrated that RGDfC-SeNPs/siRNA had negligible toxicity on the major organs of mice. In a word, this study provides a novel strategy for the design of biocompatible and effective siRNA delivery vehicles in cancer therapy.

Abstract
A cationic group has been quantitatively and selectively introduced into C6 position of each glucose units of Curdlan by "Click Chemistry" successfully. The resulting cationic Curdlan-Imidazole-lysine polymers (Cur-6-100Lys) exhibit excellent water solubility. Structure of the Cur-6-100Lys complexes was verified by FTIR and NMR spectroscopic measurements, and analysis of Cur-6-100Lys by GPC, DLS and SEM revealed that they have stoichiometric, nanosized spheroidal structures. Cytotoxicity measurement, electrophoretic mobility shift assay and EGFP-pDNA transfection have been carried out respectively. The results clearly show that Cur-6-100Lys nanocarriers have bound to dsDNA promptly, are less cytotoxic to both 7901 cells and HeLa cells, and are readily able to transport EGFP-pDNA into HepG2 cells. Our studies indicated that Cur-6-100Lys can potentially be used as a versatile nano platform for efficient gene delivery in living cells.

Reversal of multidrug resistance in breast cancer MCF-7/ADR cells by h-R3-siMDR1-PAMAM complexes. Int J Pharm 2016; 511:436-445. [PMID: 27444552 DOI: 10.1016/j.ijpharm.2016.07.039] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2016] [Revised: 07/04/2016] [Accepted: 07/18/2016] [Indexed: 12/21/2022]
Abstract
Multidrug resistance (MDR) among breast cancer cells is the paramount obstacle for the successful chemotherapy. In this study, anti-EGFR antibody h-R3 was designed to self-assembled h-R3-siRNA-PAMAM-complexes (HSPCs) via electrostatic interactions for siRNA delivery. The physicochemical characterization, cell uptake, MDR1 silencing efficiency, cell migration, cell growth and cell apoptosis were investigated. The HSPCs presented lower cytotoxicity, higher cellular uptake and enhanced endosomal escape ability. Also, HSPCs encapsulating siMDR1 knockdowned 99.4% MDR1 gene with up to ∼6 times of enhancement compared to naked siMDR1, increased the doxorubicin accumulation, down-regulated P-glycoprotein (P-gp) expression and suppressed cellular migration in breast cancer MCF-7/ADR cells. Moreover, the combination of anticancer drug paclitaxel (PTX) and siMDR1 loaded HSPCs showed synergistic effect on overcoming MDR, which inhibited cell growth and induced cell apoptosis. This h-R3-mediated siMDR1 delivery system could be a promising vector for effective siRNA therapy of drug resistant breast cancer.
