Abstract:
PURPOSE: A cationic phospholipids liposome containing 1,2-dioleoyl-sn-glycero-3-ethyl phosphocholine(DOPC) and sterol compounds is provided to enhance drug delivery efficiency and to remarkably reduce cytotoxicity. CONSTITUTION: A composition for lung-specific drug delivery comprises a cationic phospholipids nanoparticles containing 1,2-dioleoyl-sn-glycero-3-ethyl phosphocholine(DOPC) and sterol compounds. The sterol compounds are 3b-[N-(N',N'-dimethylaminoethane)-cabamyl]cholesterol(DC-Chol), stigmasterol, campesterol, sitosterol, ergosterol, lanosterol, dinosterol, gorgosterol, avenasterol, saringosterol, or fucosterol. The drug is anticancer drug.
Abstract:
The present invention relates to a therapeutic agent for treatment of neurodegenerative diseases, more specifically a composition containing an inhibitor for the activation and expression of ALK (anaplastic lymphoma kinase) for treating neurodegenerative diseases casued by the phosphorylation or coagulation of tau protein.
Abstract:
PURPOSE: A method for preparing a transgenic dementia animal of Alzheimer type is provided to express human delta-tau protein in cerebral cortex, hippocampus, and bovine brain and to enhance hyperphosphorylation and agglomeration of tau protein. CONSTITUTION: A vector for transformation contains BAI1-AP4 promoter and human delt-tau gene encoding 1-421th amino acid region cutting between 421th(aspartic acid, Asp421) and 422th amino acids in tau protein C-terminal. BAI1-AP4 promoter is a promoter which specifically expresses in cerebral cortex and Hippocampus region of a mouse. A transgenic dementia animal(deposit number: KCTC11622BP) of Alzheimer type is prepared by introducing the vector. A method for preparing the animal comprises: a step of constructing the vector; a step of injecting the vector to a fertilized egg; and a step of performing implantation of the fertilized egg to an animal.
