Abstract:
A pharmaceutical composition is provided to increase transcriptional activity of p53 and cell death by hindering analysis of p53 by MDM2 and to have anticancer effect suppressing dysplasia and carcinogenesis of cell. A pharmaceutical composition shows anticancer effect by including p19Ras protein as active component, uniting p19Ras protein with p53 protein and increasing activity of the p53 protein. The p19Ras protein is indicated as amino acid sequence of a sequence listing sequence number 1. The cancer is breast cancer, ovarian cancer, liver cancer, lung cancer, colon carcinoma or prostate cancer. An activity of the p53 protein is increased by hindering ubiquitination of p53 by MDM2.
Abstract:
PURPOSE: A pharmaceutical composition for preventing and treating cancer, which contains an expression vector containing p19ras gene or p19ras protein is provided to suppress abnormal proliferation. CONSTITUTION: A pharmaceutical composition for preventing or treating cancer contains an expression vector of p19ras gene or p19ras protein. The p19ras gene is denoted by sequence of the sequence number 1. The cancer is a cancer in which NSE is overexpressed.
Abstract:

Abstract:
A method for searching proteins uniting with bait protein is provided to confirm bond with various kinds of protein families through one immunoprecipitation experiment. A method for searching proteins uniting with bait protein comprises steps of: assembling protein which wants to confirm bond with the bait protein and making antibody full set; implementing Western blot with the bait protein using the antibody full set and obtaining a result; comparing a result of the Western blot with a ruler of the antibody full set and confirming whether bond is performed or not. A method for manufacturing the ruler comprises steps of: loading cell lysate of cell strain for expressing the bait protein and separating protein within the cell lysate by using SDS-PAGE; assembling the protein which wants to confirm bond with the bait protein and making the antibody full set; implementing Western blot using antibody of the antibody full set; and comparing results with a size marker and linearizing and indicating it.
Abstract:
PURPOSE: A pharmaceutical composition containing TIP60 is provided to induce transcription activity of a target gene promoter and to relieve or treat retinal diseases. CONSTITUTION: A pharmaceutical composition for relieving or treating retinal diseases contains TIP60 as an active ingredient. TIP60 binds to NRL protein. TIP60 contains chromo domain and histone aceytltransferase domain. The activation of TIP60 is measured by increasing transcription activity of NRL protein.
Abstract:
PURPOSE: A neurodegenerative disease-related CP2 transcription factor is provided to treat neurodegenerative diseases without side effects. CONSTITUTION: A kit for diagnosing neurodegenerative diseases comprises a nucleotide sequence of CP2 of sequence number 1, complementary sequence of the nucleotide, nucleotide fragment, or an antibody or aptamer which specifically binds to CP2 protein of sequence number 2. The kit is a microarray. A method for screening a material which prevents or treats neurodegenerative diseases comprises: a step of contacting a sample to cells containing CP2 gene or protein; and a step of measuring expression level of CP2 gene, CP2 protein level, or CP2 protein activity.
