Hydrophobically Modified siRNAs Silence Huntingtin mRNA in Primary Neurons and Mouse Brain.

Molecular therapy. Nucleic acids

Alterman JF, Hall LM, Coles AH, Hassler MR, Didiot MC, Chase K, Abraham J, Sottosanti E, Johnson E, Sapp E, Osborn MF, Difiglia M, Aronin N, Khvorova A.
PMID: 26623938
Mol Ther Nucleic Acids. 2015 Dec 01;4:e266. doi: 10.1038/mtna.2015.38.

Applications of RNA interference for neuroscience research have been limited by a lack of simple and efficient methods to deliver oligonucleotides to primary neurons in culture and to the brain. Here, we show that primary neurons rapidly internalize hydrophobically...

Thermally stable coexistence of liquid and solid phases in gallium nanoparticles.

Nature materials

Losurdo M, Suvorova A, Rubanov S, Hingerl K, Brown AS.

Nat Mater. 2016 Sep;15(9):995-1002. doi: 10.1038/nmat4705. Epub 2016 Jul 25.

Gallium (Ga), a group III metal, is of fundamental interest due to its polymorphism and unusual phase transition behaviours. New solid phases have been observed when Ga is confined at the nanoscale. Herein, we demonstrate the stable coexistence, from...

Primary neurons represent an ideal cellular system for the identification of therapeutic oligonucleotides for the treatment of neurodegenerative diseases. However, due to the sensitive nature of primary cells, the transfection of small interfering RNAs (siRNA) using classical methods is...

Comparative route of administration studies using therapeutic siRNAs show widespread gene modulation in Dorset sheep.

PMID: 34935646
JCI Insight. 2021 Dec 22;6(24). doi: 10.1172/jci.insight.152203.

siRNAs comprise a class of drugs that can be programmed to silence any target gene. Chemical engineering efforts resulted in development of divalent siRNAs (di-siRNAs), which support robust and long-term efficacy in rodent and nonhuman primate brains upon direct...

This work demonstrates a controlled van der Waals growth of two-dimensional SnTe nanoplates on mica substrates and their applications in flexible near-infrared photodetectors. The growth of nonlayered rock-salt structured SnTe crystals into two-dimensional SnTe nanoplate structures is mainly caused...

Exosomes can serve as delivery vehicles for advanced therapeutics. The components necessary and sufficient to support exosomal delivery have not been established. Here we connect biochemical composition and activity of exosomes to optimize exosome-mediated delivery of small interfering RNAs...

Single-Stranded Phosphorothioated Regions Enhance Cellular Uptake of Cholesterol-Conjugated siRNA but Not Silencing Efficacy.

Molecular therapy. Nucleic acids

Ly S, Echeverria D, Sousa J, Khvorova A.
PMID: 32818923
Mol Ther Nucleic Acids. 2020 Sep 04;21:991-1005. doi: 10.1016/j.omtn.2020.07.029. Epub 2020 Jul 25.

Small interfering RNAs (siRNAs) have potential to silence virtually any disease-causing gene but require chemical modifications for delivery to the tissue and cell of interest. Previously, we demonstrated that asymmetric, phosphorothioate (PS)-modified, chemically stabilized, cholesterol-conjugated siRNAs, called hsiRNAs, support...
