要旨

Gold glyconanoparticles (GlycoNPs) are full of promise in areas like biomedicine, biotechnology and materials science due to their amazing physical, chemical and biological properties. Here, siRNA GlycoNPs (AuNP@PEG@Glucose@siRNA) in comparison with PEGylated GlycoNPs (AuNP@PEG@Glucose) were applied in vitro to a luciferase-CMT/167 adenocarcinoma cancer cell line and in vivo via intratracheal instillation directly into the lungs of B6 albino mice grafted with luciferase-CMT/167 adenocarcinoma cells. siRNA GlycoNPs but not PEGylated GlycoNPs induced the expression of pro-apoptotic proteins such as Fas/CD95 and caspases 3 and 9 in CMT/167 adenocarcinoma cells in a dose dependent manner, independent of the inflammatory response, evaluated by bronchoalveolar lavage cell counting. Moreover, in vivo pulmonary delivered siRNA GlycoNPs were capable of targeting c-Myc gene expression (a crucial regulator of cell proliferation and apoptosis) via in vivo RNAi in tumour tissue, leading to an ∼80% reduction in tumour size without associated inflammation.

Nanoscale is a high-impact international journal, publishing high-quality research across nanoscience and nanotechnology. Nanoscale publishes a full mix of research articles on experimental and theoretical work, including reviews, communications, and full papers. Highly interdisciplinary, Nanoscale appeals to scientists, researchers and professionals interested in nanoscience and nanotechnology, quantum materials and quantum technology, including the areas of physics, chemistry, biology, medicine, materials, energy/environment, information technology, detection science, healthcare and drug discovery, and electronics. For publication in Nanoscale, papers must report high-quality reproducible new work that will be of significant general interest to the journal's wide international readership. Nanoscale is a collaborative venture between the Royal Society of Chemistry Publishing and a leading nanoscience research centre, the National Center for Nanoscience and Technology (NCNST) in Beijing, China. image block The journal publishes weekly issues, complementing and building on the nano content already published across the Royal Society of Chemistry Publishing journal portfolio. Since its launch in late 2009, Nanoscale has established itself as a platform for high-quality, cross-community research that bridges the various disciplines involved with nanoscience and nanotechnology, publishing important research from leading international research groups.
