Abstract:
PURPOSE: An anticancer drug containing p53 fragment A is provided to suppress MEK/ERK activation and infiltration of cancer cells. CONSTITUTION: A polypeptide having anti-cancer activity contains 46-340 amino acids of sequence number 2. The polypeptide contains 160-206th amino acid in p53R2 amino acid sequence of sequence number 1. The polypeptide comprises an amino acid sequence selected from sequence numbers 2-4. An expression vector contains a polynucleotide encoding the polypeptide. An anticancer drug contains the polypeptide or the expression vector containing the same as an active ingredient. The cancer is lung cancer, breast cancer, ovarian cancer, kidney cancer, or prostate cancer.
Abstract:
본발명은 PIG3를이용한 DNA 손상보호방법에관한것으로, 보다상세하게는 PIG3(p53-inducible gene 3)가자외선(UV) 또는방사능유사약물(radiomimetic drug) 등의 DNA 손상인자(DNA damaging agents)에대한세포의민감도를억제하고, DNA 손상에대한회복에관여하며, DNA 손상점검점경로의활성에관여하며, DNA 손상에대한반응에서핵내응집체를형성하고, Chk1, Chk2 및 H2AX의인산화에관여하며, ATM 및 ATR의다운스트림으로기능함으로써, 상기 PIG3가 DNA 손상반응경로의중요한구성성분이며 DNA 손상신호전달에직접적인역할을하는것을알 수있으므로 DNA 손상보호에유용하게이용할수 있다.
Abstract:
PURPOSE: A composition containing Ape1/Ref-1(Apurinic/apyrimidinic endonuclease 1) is provided to induce neurite generation, to protect neural cells, and to prevent and treat neurodegenerative diseases. CONSTITUTION: A polypeptide enhancing the expression of glial cell-derived neurotropic factor receptor alpha 1(GFR alpha 1) comprises 100-150 amino acids contains 1-100th amino acids which are Ape1/Ref-1 oxidation/reduction domain. The Ape1/Ref-1 oxidation/reduction domain has an amino acid sequence of sequence number 2. A polynucleotide encoding the polypeptide has a nucleotide sequence of sequence number 3. A composition for preventing and treating neurodegenerative diseases contains the Ape1/Ref-1 oxidation/reduction domain or expression vector thereof.
Abstract:
PURPOSE: A method for screening an inhibitor of AMPK activation is provided to select a material which suppresses inter-combination of AMPKγ1 and DNA-PKcs and to use as an anticancer drug. CONSTITUTION: A method for screening drug for suppressing cancer proliferation and/or metastasis or protecting nerve comprises: a step of treating a candidate material which suppresses inter-combination of AMPKγ1 and DNA-PKcs (experimental group); a step of measuring activation of inter-combination of AMPKγ1 and DNA-PKcs(positive control group) and inter-combination of the experimental group; and a step of selecting candidate material over the positive control group.
Abstract:
PURPOSE: A composition and method for protecting DNA damage using PIG3 are provided to suppress cytotoxicity and to relate to normal recognition in DNA damage. CONSTITUTION: An anti-cancer aid contains an inhibitor for expression or activation of PIG3(p53-inducible gene 3). The PIG3 has an amino acid sequence of sequence number 1. The inhibitor for expression of PIG3 is an antisense nucleotide which complementarily binds to mRNA of PIG3 gene, small interfering RNA(siRNA) or small hairpin RNA(shRNA). The inhibitor for expression or activation of PIG3 treats and prevents cancer by administering to cancer cells. A cosmetic composition for anti-aging contains PIG3 gene construct as an active ingredient. The PIG3 gene has a nucleotide sequence of sequence number 2.
