"Nucleic Acid Drug Delivery: Triumphs and Challenges" explores the potential of RNA interference (RNAi) as a targeted cancer therapy, offering a more precise and effective alternative to conventional chemotherapy. The book discusses how RNAi, through small interfering RNA (siRNA) and microRNA (miRNA), can selectively silence oncogenes, thereby reducing the off-target effects and toxicity associated with traditional treatments. It also addresses the challenges of RNA delivery, focusing on advancements like lipid nanoparticles (LNPs) and other novel systems designed to enhance stability,...
