Abstract
1. Use of (v) a gene coding for a protein phosphatase 1 E having SEQ ID NO:1 or SEQ ID NO:2, and/or (vi) a transcription product of the gene coding for a protein phosphatase 1 E having SEQ ID NO:1 or SEQ ID NO:2, and/or (vii) a translation product of the gene coding for a protein phosphatase 1 E having SEQ ID NO:1 or SEQ ID NO:2, and/or (viii) a fragment, or derivative, or variant of (i) to (iii). for identifying or for testing agents for the treatment and/or prevention of neurodegenerative diseases.
Claims3
A method for identifying putative agents for the treatment of Alzheimer's disease, said method comprising:
- (a) contacting an agent with a phosphorylated substrate and with a protein phosphatase 1 E having SEQ ID NO:1 or SEQ ID NO:2,
- (b) measuring the enzymatic activity of said protein phosphatase 1 E having SEQ ID NO:1 or SEQ ID NO:2,
- (c) comparing the enzymatic activity measured in step (b) with the enzymatic activity of a protein phosphatase 1 E having SEQ ID NO:1 or SEQ ID NO:2 not contacted with said agent,
- (d) identifying agents that decrease the enzymatic activity of said protein phosphatase 1 E having SEQ ID NO:1 or SEQ ID NO:2 as putative agents for the treatment of Alzheimer's disease.
A method for identifying putative agents for the treatment of Alzheimer's disease, said method comprising:
- (a) contacting a sample comprising an expression system for expression of a protein phosphatase 1 E having SEQ ID NO:1 or SEQ ID NO:2 with an agent
- (b) measuring the expression level of the gene coding for a protein phosphatase 1 E having SEQ ID NO:1 or SEQ ID NO:2, and/or a transcription product of the gene coding for protein phosphatase 1 E having SEQ ID NO:1 or SEQ ID NO:2 in said sample
- (c) comparing the expression level measured in step (b) with the expression level of a gene coding for a protein phosphatase 1 E having SEQ ID NO:1 or SEQ ID NO:2, and/or a transcription product of the gene coding for a protein phosphatase 1 E having SEQ ID NO:1 or SEQ ID NO:2 measured in a sample comprising an expression system for expression of a protein phosphatase 1 E having SEQ ID NO:1 or SEQ ID NO:2 not contacted with said agent,
- (d) identifying agents that decrease the expression level of a gene coding for a protein phosphatase 1 E having SEQ ID NO:1 or SEQ ID NO:2, and/or a transcription product of the gene coding for a protein phosphatase 1 E having SEQ ID NO:1 or SEQ ID NO:2 as putative agents for the treatment of Alzheimer's disease.
A method for identifying putative agents for the treatment of Alzheimer's diseases, said method comprising:
- (a) contacting a neuronal cell which expresses a protein phosphatase 1 E having SEQ ID NO:1 or SEQ ID NO:2 with an agent
- (b) determining the number of dendritic spines and/or dendritic spine density in said cell
- (c) comparing the number of dendritic spines and/or the dendritic spine density determined in step (b) with the number of dendritic spines and/or dendritic spine density in a cell which expresses a protein phosphatase 1 E having SEQ ID NO:1 or SEQ ID NO:2 not contacted with said agent,
- (d) identifying agents that increase the number of dendritic spines and/or dendritic spine density as putative agents for the treatment of Alzheimer's disease.
