J Biomol Struct Dyn 2023:1-7. [PMID: 37975333 DOI: 10.1080/07391102.2023.2283145] [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: 08/08/2023] [Accepted: 11/08/2023] [Indexed: 11/19/2023]
Abstract
Sulfate polysaccharides can inhibit DNA digestion in simulated gastric juice in vitro, which is important for regulating dietary nucleic acids metabolism, but the mechanism of inhibition is unclear. This study used dextran sulfate (DS) with different sulfate groups and molecular weights to explore the effect of DS on DNA digestion. Molecular interactions between DS and DNA were investigated by biolayer interferometry (BLI), isothermal titration calorimetry (ITC) and molecular dynamics simulations. Results indicated that DS with higher molecular weight and sulfate group content showed stronger inhibitory effect of DNA digestion. ITC results showed that the combined Kd value of DNA and DS was about 2.53 mM. The main reason for inhibition of DNA digestion is that the formation of hydrogen bonds between the sulfate group of DS and DNA bases hinders the binding of DNA to pepsin. This finding will facilitate new strategies for nucleic acid metabolism and oral drug delivery.Communicated by Ramaswamy H. Sarma.

Abstract
Cystic fibrosis (CF), a lethal hereditary disease caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene coding for an epithelial chloride channel, is characterized by an imbalanced homeostasis of ion and water transports in secretory epithelia. As the disease is single-gene based, transcript therapy using therapeutic mRNA is a promising concept of treatment in order to correct many aspects of the fatal pathology on a cellular level. Hence, we developed chitosan nanocapsules surface-loaded with wtCFTR-mRNA to restore CFTR function. Furthermore, we loaded the nanocapsules with capsaicin, aiming to enhance the overall efficiency of transcript therapy by reducing sodium hyperabsorption by the epithelial sodium channel (ENaC). Dynamic light scattering with non-invasive back scattering (DLS-NIBS) revealed nanocapsules with an average hydrodynamic diameter of ~200 nm and a Zeta potential of ~+60 mV. The results of DLS-NIBS measurements were confirmed by asymmetric flow field-flow fractionation (AF4) with multidetection, while transmission electron microscopy (TEM) images confirmed the spherical morphology and size range. After stability measurements showed that the nanocapsules were highly stable in cell culture transfection medium, and cytotoxicity was ruled out, transfection experiments were performed with the CF cell line CFBE41o-. Finally, transepithelial measurements with a new state-of-the-art Ussing chamber confirmed successfully restored CFTR function in transfected cells. This study demonstrates that CS nanocapsules as a natural and non-toxic delivery system for mRNA to target cells could effectively replace risky vectors for gene delivery. The nanocapsules are not only suitable as a transcript therapy for treatment of CF, but open aspiring possibilities for safe gene delivery in general.

Delivery of plasmid DNA to shrimp hemocytes by Infectious hypodermal and hematopoietic necrosis virus (IHHNV) nanoparticles expressed from a baculovirus insect cell system. J Invertebr Pathol 2019; 166:107231.

Abstract
Virus-like particles (VLPs) are potential containers for delivery of therapeutic agents at the nanoscale. In this study, the capsid protein of Infectious hypodermal and hematopoietic necrosis virus (IHHNV) was expressed in a baculovirus insect cell system. The 37-kDa recombinant protein containing the hexahistidine residues (His Tag) at N-terminal was purified using immobilized metal affinity chromatography (IMAC) and assembled into VLPs with a diameter of 23 ± 3 nm analyzed by transmission electron microscopy. We also verified that disassembly/reassembly of IHHNV-VLPs was controlled in the presence and absence of DTT. The efficiency of IHHNV-VLPs to encapsulate plasmid DNA was about 48.2%, and the VLPs encapsulating the pcDNA3.1(+)-EGFP plasmid DNA could recognize the primary shrimp hemocytes and deliver the loaded plasmid into cells by detection of expressed enhanced green fluorescent protein (EGFP). These results implied that the IHHNV-VLPs might be a good candidate for packaging and delivery of expressible plasmid DNA, and may produce an antiviral product in shrimp cells for gene therapy.

Abstract
The activation of the innate RNA interference pathway through double-stranded RNAs (dsRNAs) is one of the approaches to protecting shrimp from viruses. Previous studies have shown that injection of specific dsRNAs can successfully inhibit viral infection in shrimp. However, inhibition requires high levels of dsRNA and dsRNA stability in shrimp is limited. Virus-like particles (VLPs) have been applied to deliver nucleic acids into host cells because of the protection of dsRNAs from host endonucleases as well as the target specificity provided by VLPs. Therefore, this study aimed to develop Penaeus stylirostris densovirus (PstDNV) VLPs for dsRNA deliver to shrimp. The PstDNV capsid protein was expressed and can be self-assembled to form PstDNV VLPs. Co-expression of dsRNA-YHV-Pro and PstDNV capsid protein was achieved in the same bacterial cells, whose structure was displayed as the aggregation of VLPs by TEM. Tested for their inhibiting yellow head virus (YHV) from infecting shrimp, the dsRNA-YHV-Pro-PstDNV VLPs gave higher levels of YHV suppression and a greater reduction in shrimp mortality than the delivery of naked dsRNA-YHV-Pro. Therefore, PstDNV-VLPs are a promising vehicle for dsRNA delivery that maintains the anti-virus activity of dsRNA in shrimp over a longer period of time as compared to native dsRNAs.
