Lipid Nanoparticles: A Novel Gene Delivery Technique for Clinical Application
Curr Issues Mol Biol. 2022 Oct 19;44(10):5013-5027. doi: 10.3390/cimb44100341.ABSTRACTLipid nanoparticles (LNPs) are an emerging vehicle for gene delivery that accommodate both nucleic acid and protein. Based on the experience of therapeutic liposomes, current LNPs have been developed based on the chemistry of lipids and RNA and on the biology of human disease. LNPs have been used for the development of Onpattro, an siRNA drug for transthyretin-mediated amyloidosis, in 2018. The subsequent outbreak of COVID-19 required a vaccine for its suppression. LNP-based vaccine production received much attention for this and resulted...

Mechanisms and challenges of nanocarriers as non-viral vectors of therapeutic genes for enhanced pulmonary delivery
J Control Release. 2022 Nov 10:S0168-3659(22)00739-8. doi: 10.1016/j.jconrel.2022.10.061. Online ahead of print.ABSTRACTWith the rapid development of biopharmaceuticals and the outbreak of COVID-19, the world has ushered in a frenzy to develop gene therapy. Therefore, therapeutic genes have received enormous attention. However, due to the extreme instability and low intracellular gene expression of naked genes, specific vectors are required. Viral vectors are widely used attributed to their high transfection efficiency. However, due to the safety concerns of viral vectors, nanotechnology-based non-viral vectors have attrac...

Viruses, Vol. 15, Pages 100: RNA Interference Approach Is a Good Strategy against SARS-CoV-2
ng-Huang Shen COVID-19, caused by SARS-CoV-2, created a devastating outbreak worldwide and consequently became a global health concern. However, no verifiable, specifically targeted treatment has been devised for COVID-19. Several emerging vaccines have been used, but protection has not been satisfactory. The complex genetic composition and high mutation frequency of SARS‑CoV‑2 have caused an uncertain vaccine response. Small interfering RNA (siRNA)-based therapy is an efficient strategy to control various infectious diseases employing post-transcriptional gene silencing through the silencin...

Use of Iontophoresis Technology for Transdermal Delivery of a Minimal mRNA Vaccine as a Potential Melanoma Therapeutic
Biol Pharm Bull. 2023;46(2):301-308. doi: 10.1248/bpb.b22-00746.ABSTRACTmRNA vaccines have attracted considerable attention as a result of the 2019 coronavirus pandemic; however, challenges remain regarding use of mRNA vaccines, including insufficient delivery owing to the high molecular weights and high negative charges associated with mRNA. These characteristics of mRNA vaccines impair intracellular uptake and subsequent protein translation. In the current study, we prepared a minimal mRNA vaccine encoding a tumor associated antigen human gp10025-33 peptide (KVPRNQDWL), as a potential treatment for melanoma. Minimal mRNA...

SARS-COV-2 spike protein promotes RPE cell senescence via the ROS/P53/P21 pathway
In conclusions, the S-protein of SARS-Cov-2 induces cellular senescence of ARPE-19 cells in vitro and the expression of senescence-associated cytokines in zebrafish retina in vivo likely by activating ER stress, ROS, and NF-κb. These results may uncover a potential association between SARS-cov-2 infection and development of AMD.PMID:36738354 | DOI:10.1007/s10522-023-10019-0
