Therapeutic methods and medicines may be developed by identifying a gene responsible for progressive supranuclear palsy, as may effective therapeutic methods and medicines. A medicine for progressive supranuclear palsy may contain a compound for inhibiting the expression of a filamin-A gene is provided. Also provided is an assessment system that uses cells expressing filamin-A, which is used in the search for medicaments for progressive supranuclear palsy or their candidates.

The instant invention provides for novel catiome lipids that can be used in combination with other lipid components such as cholesterol and PEG-lipids to form lipid nanoparticles with oligonucleotides. It is an object of the instant invention to provide a cationic lipid scaffold that demonstrates enhanced efficacy along with lower liver toxicity as a result of lower lipid levels in the liver. The present invention employs low molecular weight cationic lipids with one short lipid chain to enhance the efficiency and tolerability of in vivo delivery of siRNA.
