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.
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:
The present invention relates to a medicine for treating neurodegenerative disease and, more specifically, to a composition for preventing and treating tau protein-mediated neurodegenerative disease, comprising pimozide as an active ingredient, whereby neurodegenerative disease is caused by phosphorylation and aggregation of tau proteins.
Abstract:
PURPOSE: A lifespan-extended transgenic animal and a method for preparing the same are provided to extend the life span of an animal by overexpressing Atg5 gene. CONSTITUTION: A method for preparing a lifespan-extended transgenic animal is as follows. After Atg5 gene is sub-cloned in a transformation vector, a transformation cassette is separated. The separated transformation cassette is injected into the mammal embryo bud except for the human and fertilized egg is manufactured. The transformation animal is produced by implanting a fertilized egg in the surrogate mother mammal except for the human.
