Article Abstract

siRNA delivery remains a major challenge in RNAi-based therapy. Here, we report for the first time that an amphiphilic dendrimer is able to self-assemble into adaptive supramolecular assemblies upon interaction with siRNA, and effectively delivers siRNAs to various cell lines, including human primary and stem cells, thereby outperforming the currently available nonviral vectors. In addition, this amphiphilic dendrimer is able to harness the advantageous features of both polymer and lipid vectors and hence promotes effective siRNA delivery. Our study demonstrates for the first time that dendrimer-based adaptive supramolecular assemblies represent novel and versatile means for functional siRNA delivery, heralding a new age of dendrimer-based self-assembled drug delivery in biomedical applications.

Introduction: Liposomes are versatile delivery systems for encapsulating small interfering RNAs (siRNAs) because they enhance cellular uptake and gene silencing. This study compares the new liposome formula to commercial lipofectamine in delivering siRNAs targeting hepatic carcinoma genes, focusing on HNF4-α and PFKFB4.

Methods: Flow cytometry and confocal microscopy revealed efficient internalization of PE-Rhod- B labeled lipoplexes in HepG2 cells, while cytotoxicity assays demonstrated significant reductions in cell viability, particularly with siHNF4-α and siPFKFB4.

Efficient and safe carriers of genetic material are crucial for advancing gene therapy. Three new series of cationic dendritic nanocarriers based on a carbosilane scaffold, differentiated by peripheral modifications: saccharide (CS-glyco), amine (CS-N), and phosphonium dendrimers (CS-P) were designed for binding, protecting, and releasing polyanionic compounds like therapeutic siRNA. Besides introducing synthetic methodology, this study brings a unique direct interstructural comparison of 16 dendritic nanovector's characteristics, addressing a gap in typical research that focuses on uniform structural types.

Small interfering RNAs (siRNAs) have been successfully used as therapeutics to silence disease-causing genes when conjugated to ligands or formulated in lipid nanoparticles to target relevant cell types for efficacy while sparing other cells for safety. To support the development of new methods for delivery of siRNA therapeutics, we developed and characterized a panel of antibodies generated against chemically modified nucleotides used in therapeutic siRNA molecules, identifying a monoclonal antibody that detects a broad range of siRNA representing distinct sequences and modification patterns. By integrating this anti-siRNA antibody with additional reagents, we created a multiplex siRNA immunoassay that simultaneously quantifies siRNA uptake, trafficking, and silencing activity.

Chemotherapy remains the primary treatment modality for breast cancer (BCa) patients. However, chemoresistance commonly arises in clinical settings, contributing to poor prognosis. The development of chemoresistance is a dynamic and complex process involving the activation of oncogenes and inactivation of tumor suppressor genes.
