Nanoparticle-mediated delivery of siRNA represents a promising strategy to target and silence genes critical for pancreatic cancer progression. These systems offer enhanced stability, targeted delivery to tumor sites, and improved cellular uptake, overcoming limitations of free siRNA. Research focuses on designing biocompatible nanoparticles that can encapsulate siRNA, escape endosomal entrapment, and release their payload efficiently within cancer cells, ultimately leading to gene knockdown and therapeutic effects. This approach holds potential for overcoming treatment resistance and improving patient outcomes [1].
Lipid nanoparticles (LNPs) are emerging as a leading platform for siRNA delivery in pancreatic cancer. Their ability to form stable complexes with siRNA, protect it from degradation, and facilitate endosomal escape is crucial for therapeutic efficacy. This work reviews recent developments in LNP formulation, including the use of ionizable lipids and helper lipids, and their impact on delivery efficiency and safety. Targeted LNPs, functionalized with ligands that bind to pancreatic cancer-specific receptors, are also discussed as a means to improve tumor accumulation and reduce off-target effects [2].
Polymeric nanoparticles offer a versatile platform for siRNA delivery in pancreatic cancer, allowing for tunable properties such as size, charge, and drug loading. Cationic polymers can electrostatically complex with anionic siRNA, forming stable nanoparticles that protect the genetic material. The review highlights various biodegradable polymers, including PLGA and chitosan derivatives, employed in siRNA delivery systems. Strategies to enhance cellular uptake and endosomal escape, such as incorporating targeting ligands or pH-sensitive linkers, are explored to improve therapeutic outcomes [3].
Exosomes, naturally occurring extracellular vesicles, are being explored for siRNA delivery in pancreatic cancer due to their inherent biocompatibility and ability to cross biological barriers. Pancreatic cancer cells can be engineered to overexpress exosomal proteins or loaded with siRNA, which is then secreted within exosomes. This approach offers targeted delivery and immune evasion. This study investigates the potential of exosome-based siRNA delivery to suppress key oncogenes involved in pancreatic cancer growth and metastasis [4].
Targeting gene expression with siRNA delivered by nanoparticles can overcome resistance mechanisms in pancreatic cancer, such as the overexpression of drug efflux pumps or anti-apoptotic proteins. This research focuses on designing nanocarriers that can specifically accumulate in the tumor microenvironment and deliver siRNA to cancer cells that have developed resistance to conventional chemotherapy. The study explores how this approach can synergistically enhance the efficacy of existing treatments [5].
The tumor microenvironment (TME) presents significant challenges for effective siRNA delivery in pancreatic cancer, including dense stroma and immunosuppression. Nanoparticle-based systems are being developed to penetrate this barrier and reach cancer cells. This work examines how nanoparticles can be engineered to evade stromal components and deliver siRNA payloads that modulate the TME, potentially making it more permissive to anti-cancer therapies and immune infiltration [6].
