A Straightforward Method for the Development of Positively Charged Gold Nanoparticle-Based Vectors for Effective siRNA Delivery. Molecules 2023; 28:molecules28083318. [PMID: 37110552 PMCID: PMC10144622 DOI: 10.3390/molecules28083318] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 03/31/2023] [Accepted: 04/05/2023] [Indexed: 04/29/2023] Open
Abstract
The therapeutic potential of short interfering RNA (siRNA) to treat many diseases that are incurable with traditional preparations is limited by the extensive metabolism of serum nucleases, low permeability through biological membrane barriers because of a negative charge, and endosomal trapping. Effective delivery vectors are required to overcome these challenges without causing unwanted side effects. Here, we present a relatively simple synthetic protocol to obtain positively charged gold nanoparticles (AuNPs) with narrow size distribution and the surface modified with Tat-related cell-penetrating peptide. The AuNPs were characterized using TEM and the localized surface plasmon resonance technique. The synthesized AuNPs showed low toxicity in experiments in vitro and were able to effectively form complexes with double-stranded siRNA. The obtained delivery vehicles were used for intracellular delivery of siRNA in an ARPE-19 cell line transfected with secreted embryonic alkaline phosphatase (SEAP). The delivered oligonucleotide remained intact and caused a significant knockdown effect on SEAP cell production. The developed material could be useful for delivery of negatively charged macromolecules, such as antisense oligonucleotides and various RNAs, particularly for retinal pigment epithelial cell drug delivery.

Phage-mimicking nanoagents for rapid depolymerase specificity screening against multidrug resistant bacteria. Biosens Bioelectron 2022; 213:114444. [PMID: 35691082 DOI: 10.1016/j.bios.2022.114444] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Revised: 05/26/2022] [Accepted: 05/30/2022] [Indexed: 11/23/2022]
Abstract
With the rise of drug resistance, bacteriophages and bacteriophage-derived proteins may become an efficient successor to traditional antibiotics. While the enormous natural diversity of the phages allows matching virtually any bacteria, identification of the potentially life-saving phage is currently a tedious and time-consuming challenge that often cannot be performed within a reasonable time. Here we show a rapid 1-min bacteriophage screening assay based on specially constructed phage-mimicking nanoagents and surface plasmon resonance effect. Within the assay, a panel of phage-mimicking gold nanoparticles, possessing the specificity and enzymatic activity of a particular phage, is mixed with a suspension of the bacteria of interest. The spectral behaviour of the assay mix allows measurement of two critical parameters of the nanoagents and the corresponding bacteriophages: 1) direct assessment of their specificity due to convergence of the particles on the cell walls, and more importantly, 2) real-time evaluation of their enzymatic activity for the destruction of the cell capsule via detection of nanoagent detachment from the surface of bacteria. The proposed assay overcomes the current time limitations of the phage-bacteria matching procedures and thereby can facilitate faster development and adoption of phage-based therapies as a much-needed alternative to traditional antibiotics.

Molecules 2021; 26:molecules26133955. [PMID: 34203547 PMCID: PMC8271481 DOI: 10.3390/molecules26133955] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Revised: 06/20/2021] [Accepted: 06/23/2021] [Indexed: 11/18/2022] Open
Abstract
The effect of enhanced permeability and retention is often not sufficient for highly effective cancer therapy with nanoparticles, and the development of active targeted drug delivery systems based on nanoparticles is probably the main direction of modern cancer medicine. To meet the challenge, we developed polymer PLGA nanoparticles loaded with fluorescent photosensitive xanthene dye, Rose Bengal, and decorated with HER2-recognizing artificial scaffold protein, affibody ZHER2:342. The obtained 170 nm PLGA nanoparticles possess both fluorescent and photosensitive properties. Namely, under irradiation with the green light of 540 nm nanoparticles, they produced reactive oxygen species leading to cancer cell death. The chemical conjugation of PLGA with anti-HER2 affibody resulted in the selective binding of nanoparticles only to HER2-overexpressing cancer cells. HER2 is a receptor tyrosine kinase that belongs to the EGFR/ERbB family and is overexpressed in 30% of breast cancers, thus serving as a clinically relevant oncomarker. However, the standard targeting molecules such as full-size antibodies possess serious drawbacks, such as high immunogenicity and the need for mammalian cell production. We believe that the developed affibody-decorated targeted photosensitive PLGA nanoparticles will provide new solutions for ongoing problems in cancer diagnostics and treatment, as well in cancer theranostics.
