Current advancements in self-assembling nanocarriers-based siRNA delivery for cancer therapy
Colloids Surf B Biointerfaces. 2022 Nov 2;221:113002. doi: 10.1016/j.colsurfb.2022.113002. Online ahead of print.ABSTRACTDifferent therapeutic practices for treating cancers have significantly evolved to compensate and/or overcome the failures in conventional methodologies. The demonstrated potentiality in completely inhibiting the tumors and in preventing cancer relapse has made nucleic acids therapy (NAT)/gene therapy as an attractive practice. This has been made possible because NAT-based cancer treatments are highly focused on the fundamental mechanisms - i.e., silencing the expression of oncogenic genes responsible fo...

Novel nanocarriers for silencing anti-phagocytosis CD47 marker in acute myeloid leukemia cells
Colloids Surf B Biointerfaces. 2022 Jun 1;217:112609. doi: 10.1016/j.colsurfb.2022.112609. Online ahead of print.ABSTRACTAcute myeloid leukemia (AML), a malignant disorder of Hematopoietic stem cells, can escape immunosurveillance by over expression of the cluster of differentiation 47 (CD47) marker, which functions as an inhibitory signal, suppressing phagocytosis by binding to signal regulatory protein α (SIRPα) on macrophages. AML is treated mainly by chemotherapy, which has drastic side effects and poor outcomes for the patients. Most AML patients develop drug resistance, so other methods to treat AML are highly requ...

Host-Guest Interaction-Based Dual response core/shell nanoparticles as efficient siRNA carrier for killing breast cancer cells
Colloids Surf B Biointerfaces. 2021 Jun 11;205:111918. doi: 10.1016/j.colsurfb.2021.111918. Online ahead of print.ABSTRACTHow to overcome multiple obstacles to achieve the efficient and safe delivery of therapeutic genes is still the key to gene therapy. To address this issue, a cationic carrier consisting of polyamide-amine (HPAA-peptide-Fc) modified by an enzyme-responsive polypeptide as the core and hyperbranched polyglycerol derivative (CD-HPG) as the shell was synthesized by self-assembly. The obtained HPAA-peptide-HPG could form the compact nanocomplex with siPlk1, thus confirming the stable load of genes and subsequ...

Toxicological exploration of peptide-based cationic liposomes in siRNA delivery.
Abstract The toxicology of cationic liposomes was explored to advance clinical trials of liposome-mediated gene therapy through the analysis of a peptide cationic liposome with DOTAP as a positive control. We first investigated the delivery of luciferase siRNA by several peptide liposomes in mice bearing lung cancer A549 cell xenografts. Of these, a cationic liposome (CDO14) was selected for further investigation. CDO14 efficiently mediated IGF-1R-siRNA delivery and inhibited the growth of the A549 cell xenografts. The in vivo toxicity and toxicological mechanisms of the selected liposome were evaluated to assess ...

Novel cell-penetrating peptide-loaded nanobubbles synergized with ultrasound irradiation enhance EGFR siRNA delivery for triple negative Breast cancer therapy.
Abstract The lack of safe and effective gene delivery strategies remains a bottleneck for cancer gene therapy. Here, we describe the synthesis, characterization, and application of cell-penetrating peptide (CPP)-loaded nanobubbles (NBs), which are characterized by their safety, strong penetrating power and high gene loading capability for gene delivery. An epidermal growth factor receptor (EGFR)-targeted small interfering RNA (siEGFR) was transfected into triple negative breast cancer (TNBC) cells via prepared CPP-NBs synergized with ultrasound-targeted microbubble destruction (UTMD) technology. Fluorescence micro...

Comparison of different cationized proteins as biomaterials for nanoparticle-based ocular gene delivery.
Abstract Cationized polymers have been proposed as transfection agents for gene therapy. The present work aims to improve the understanding of the potential use of different cationized proteins (atelocollagen, albumin and gelatin) as nanoparticle components and to investigate the possibility of modulating the physicochemical properties of the resulting nanoparticle carriers by selecting specific protein characteristics in an attempt to improve current ocular gene-delivery approaches. The toxicity profiles, as well as internalization and transfection efficiency, of the developed nanoparticles can be modulated by mo...

Co-delivery of doxorubicin and siRNA by a simplified platform with oligodeoxynucleotides as a drug carrier.
In this study, a simplified and effective system for the co-loading and intracellular co-delivery of doxorubicin (Dox) and siRNA was developed. Oligodeoxynucleotides with CGA repeating units (CGA-ODNs) were introduced to load Dox. The loading mechanism was based on the ability of Dox to intercalate within double-stranded 5'-GC-3' or 5'-CG-3' sequences. Poly(ethyleneimine) (PEI) was used to condense siRNA and Dox loaded CGA-ODNs (CGA-ODNs-Dox) to obtain Dox and siRNA co-loaded nanocomplexes (PEI/CGA-ODNs-Dox&siRNA, PDR). The cellular uptake of PDR in A549 and HepG2 cells was 39.52% and 36.78%, respectively, indicating t...
