Investigating 3R In Vivo Approaches for Bio-Distribution and Efficacy Evaluation of Nucleic Acid Nanocarriers: Studies on Peptide-Mimicking Ionizable Lipid. SMALL (WEINHEIM AN DER BERGSTRASSE, GERMANY) 2022; 18:e2107768. [PMID: 35355412 DOI: 10.1002/smll.202107768] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 02/10/2022] [Indexed: 06/14/2023]
Abstract
Formulations based on ionizable amino-lipids have been put into focus as nucleic acid delivery systems. Recently, the in vitro efficacy of the lipid formulation OH4:DOPE has been explored. However, in vitro performance of nanomedicines cannot correctly predict in vivo efficacy, thereby considerably limiting pre-clinical translation. This is further exacerbated by limited access to mammalian models. The present work proposes to close this gap by investigating in vivo nucleic acid delivery within simpler models, but which still offers physiologically complex environments and also adheres to the 3R guidelines (replace/reduce/refine) to improve animal experiments. The efficacy of OH4:DOPE as a delivery system for nucleic acids is demonstrated using in vivo approaches. It is shown that the formulation is able to transfect complex tissues using the chicken chorioallantoic membrane model. The efficacy of DNA and mRNA lipoplexes is tested extensively in the zebra fish (Danio rerio) embryo which allows the screening of biodistribution and transfection efficiency. Effective transfection of blood vessel endothelial cells is seen, especially in the endocardium. Both model systems allow an efficacy screening according to the 3R guidelines bypassing the in vitro-in vivo gap. Pilot studies in mice are performed to correlate the efficacy of in vivo transfection.

[PMID: 35008249 PMCID: PMC8750096 DOI: 10.3390/cancers14010085] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2021] [Revised: 12/16/2021] [Accepted: 12/17/2021] [Indexed: 01/27/2023] Open
Abstract
Hepatocellular carcinoma (HCC) is the third-largest cause of cancer death worldwide, while immunotherapy is rapidly being developed to fight HCC with great potential. Nucleic acid drugs are the most important modulators in HCC immunotherapy. To boost the efficacy of therapeutics and amplify the efficiency of genetic materials, biocompatible polymers are commonly used. However, under the strong need of a summary for current developments of biocompatible polymeric nucleic acid carriers for immunotherapy of HCC, there is rare review article specific to this topic to our best knowledge. In this article, we will discuss the current progress of immunotherapy for HCC, biocompatible cationic polymers (BCPs) as nucleic acid carriers used (or potential) to fight HCC, the roles of biocompatible polymeric carriers for nucleic acid delivery, and nucleic acid delivery by biocompatible polymers for immunotherapy. At the end, we will conclude the review and discuss future perspectives. This article discusses biocompatible polymeric nucleic acid carriers for immunotherapy of HCC from multidiscipline perspectives and provides a new insight in this domain. We believe this review will be interesting to polymer chemists, pharmacists, clinic doctors, and PhD students in related disciplines.

MATERIALS SCIENCE & ENGINEERING. C, MATERIALS FOR BIOLOGICAL APPLICATIONS 2021; 129:112348.

Abstract
The use of viral vectors for in vivo gene therapy can be severely limited by their immunogenicity. Non-viral vectors may represent an alternative, however, reports analyzing their immunogenicity are still lacking. Here, we studied the humoral immune response in a murine model triggered by artificial virus-like particles (AVLPs) carrying plasmid or antisense DNA. The AVLPs were assembled using a family of modular proteins based on bioinspired collagen-like and silk-like sequences that produce virus-like particles. We compared our AVLPs against an Adeno Associated Virus 1 (AAV), a widely used viral vector for in vivo gene delivery that has been approved by the FDA and EMA for gene therapy. We found that a 1000-fold higher mass of AVLPs than AAV are necessary to obtain similar specific antibody titters. Furthermore, we studied the stability of AVLPs against relevant biological reagents such as heparin and fetal bovine serum to ensure nucleic acid protection in biological media. Our study demonstrates that the AVLPs are stable in physiological conditions and can overcome safety limitations such as immunogenicity. The scarce humoral immunogenicity and high stability found with AVLPs suggest that they have potential to be used as stealth non-viral gene delivery systems for in vivo studies or gene therapy.
