Cold atmospheric plasma mediated cell membrane permeation and gene delivery-empirical interventions and pertinence
Adv Colloid Interface Sci. 2023 Aug 28;320:102989. doi: 10.1016/j.cis.2023.102989. Online ahead of print.ABSTRACTDelivery of genetic material to cells is an integral tool to analyze and reveal the genetic interventions in normal cellular processes and differentiation, disease development and for gene therapy. It has profound applications in pharmaceutical, agricultural, environmental and biotechnological sectors. The major methods relied for gene delivery or transfection requires either viral vectors or xenogenic carrier molecules, which renders probabilistic carcinogenic, immunogenic and toxic effects. A newly evolved phy...

A cathepsin B/GSH dual-responsive fluorinated peptide for effective siRNA delivery to cancer cells
Bioorg Chem. 2023 Mar 20;135:106485. doi: 10.1016/j.bioorg.2023.106485. Online ahead of print.ABSTRACTSmall interfering RNA (siRNA) can be exploited to silence specific genes associated with cancer development, and successful siRNA therapy is highly dependent on the efficiency of the siRNA delivery vector. Herein, a well-designed novel redox- and enzyme-responsive fluorinated polyarginine (PFC-PR) was developed to be used as an anti-cancer siRNA carrier. The multiple guanidine groups could provide positive charges and bind with siRNA efficiently, and further fluorination modification enhanced the interaction with siRNA, re...

Molecules, Vol. 27, Pages 2082: Inhibition of Metastatic Hepatocarcinoma by Combined Chemotherapy with Silencing VEGF/VEGFR2 Genes through a GalNAc-Modified Integrated Therapeutic System
Jing Hu Hepatocellular carcinoma (HCC) is a highly malignant tumor related to high mortality and is still lacking a satisfactory cure. Tumor metastasis is currently a major challenge of cancer treatment, which is highly related to angiogenesis. The vascular endothelial growth factor (VEGF)/VEGFR signaling pathway is thus becoming an attractive therapeutic target. Moreover, chemotherapy combined with gene therapy shows great synergistic potential in cancer treatment with the promise of nanomaterials. In this work, a formulation containing 5-FU and siRNA against the VEGF/VEGFR signaling pathway into N-acetyl-galactosam...

Branched Antisense and siRNA Co-assembled Nanoplatform for Combined Gene Silencing and Tumor Therapy.
Abstract Chemically modified DNA has been widely developed to fabricate various nucleic acid nanostructures for biomedical applications. Herein, we report a facile strategy for construction of branched antisense DNA and small interfering RNA (siRNA) co-assembled nanoplatform for combined gene silencing in vitro and in vivo. In our design, the branched antisense can efficiently capture siRNA with 3' overhangs through DNA-RNA hybridization. After being equipped with an active targeting group and an endosomal escape peptide by host-guest interaction, the tailored nucleic acid nanostructure functions efficiently as bo...

Phosphorus dendrimers as powerful nanoplatforms for drug delivery, as fluorescent probes and for liposome interaction studies: A concise overview.
Abstract Gene therapy is a new and promising tool to treat many severe diseases and the silencing of proteins is the safest and the most efficient tool to treat diseases because it does not induce changes in human genome and avoids a huge problem encompassing insertional mutagenesis. Using small RNAs to switch on/off target proteins is limited due to existence of some barriers for them in the human body (blood RNAses, serum albumins, cell walls, etc). For therapeutic applications they need the efficient and non-toxic carrier which will deliver them into cell cytoplasm. Within the huge range of carriers available, ...

The Application of the RNA Interference Technologies for KRAS: Current Status, Future Perspective and Associated Challenges.
Abstract KRAS is a member of the murine sarcoma virus oncogene-RAS gene family. It plays an important role in the prevention, diagnosis and treatment of tumors during tumor cell growth and angiogenesis. KRAS is the most commonly mutated oncogene in human cancers, such as the pancreatic cancers, colon cancers, and lung cancers. Detection of KRAS gene mutation is an important indicator for tracking the status of oncogenes, illuminating the developmental prognosis of various cancers, and the efficacy of radiotherapy and chemotherapy. However, the efficacy of different patients in clinical treatment is not the same. S...

A reactive oxygen species-responsive dendrimer with low cytotoxicity for efficient and targeted gene delivery
Publication date: Available online 25 March 2019Source: Chinese Chemical LettersAuthor(s): Yueqi Wang, Changjian Li, Libo Du, Yang LiuAbstractNonviral vectors have been attracting more attention for several advantages in gene delivery and the development of nonviral gene carriers with high delivery efficiency and low cytotoxicity has long been a key project. Starburst polyamidoamine dendrimers are a class of synthetic polymers with unique structural and physical characteristics. However, when they are used as gene carrier, the gene transfection efficiency is not satisfactory. Herein, a novel thioketal-core polyamidoamine d...

Evaluation of siRNA and Cationic Liposomes Complexes as a Model for in vitro siRNA Delivery to Cancer Cells
This study aims to investigate the effect of different molar charge ratios (R+/-) between positive charges from microfluidics-produced cationic liposomes (CL) (egg phosphatidylcholine, 1,2-dioleoyl-3-trimethylammonium-propane and 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine) and negative charges from siRNA and on physico-chemical and morphological properties of the lipoplexes (CL/siRNA) as well as their in vitro luciferase silencing effect in HeLa cells. R+/- 3.27 was found to be the optimum point for complexation. This finding was confirmed by gel retardation and siRNA accessibility assays. According to Cryo-TEM analysis...
