Abstract:
PURPOSE: A composition containing death receptor 5(DR5) is provided to induce cancer cell apoptosis or TRAIL-sensitivity and to prevent or treat cancer. CONSTITUTION: An anti-DR5 antibody which specifically binds to DR5 comprises an amino acid of sequence number 7 or 39. The anti-DR5 antibody contains heavy chain variable region of amino acid sequence numbers 1, 2, and 3 and light chain variable region of amino acid sequence of sequence numbers 4, 5, and 6. The light chain variable region has an amino acid of sequence number 27 or 37. The heavy chain variable region has an amino acid sequence of sequence number 28 or 38.
Abstract:
PURPOSE: A nucleic acid hydrolysis antibody is provided to replace and supplement gene silence technique such as siRNA and to reduce target protein expression. CONSTITUTION: A nucleic acid hydrolysis antibody has intracellular infiltration ability and specifically binds to single strand/double stran target nucleic acid having specific nucleotide sequence. The target nucleic acid is G18 or Her218. G18 has a nucleotide sequence of sequence number 12. The antibody has an amino acid sequence selected from sequence numbers 14 to 24. The antibody is encodes by DNA gene having a nucleotide selected from sequence numbers 25 to 35. The antibody is entire IgG, heavy chain variable region single domain, light chain variable region single domain, single chain variable region fragement (scFv), (scFv)2, Fab, Fab', F(ab')2, diabody or dsFv.
Abstract:
PURPOSE: A humanized antibody having nucleic acid hydrolysis ability and cancer cell infiltration ability is provided to specifically bind to and hydrolyze a nucleic acid and to ensure low immune reaction in a human body. CONSTITUTION: An immunoglobulin or single side chain antibody(scFv) fragment contains epitope of heavy chain variable region or light chain variable region. The immunoglobulin is immunoglobulin G, humanized 3D8 antibody. The heavy chain variable region is a protein comprising a sequence of sequence number 15. The VL is a protein comprising a sequence of sequence number 16. A composition for preventing or treating cancer contains the immunoglobulin or single side chain antibody(scFv) fragment as an active ingredient.
Abstract:
본 발명은 세포사멸 수용체 5 (death receptor 5; DR5)에 특이적으로 결합하는 항체 및 이를 포함하는 암 예방 또는 치료용 조성물에 관한 것으로, 상보성 결정 영역에 서열번호 1 내지 3의 아미노산 서열을 갖는 중쇄 가변영역 및 서열번호 4 내지 6의 아미노산 서열을 갖는 경쇄 가변영역을 포함하는 항체; 및 상보성 결정 영역에 서열번호 7 내지 9의 아미노산 서열을 갖는 중쇄 가변영역 및 서열번호 10 내지 12의 아미노산 서열을 갖는 경쇄 가변영역을 포함하는 항체로 이루어지는 군으로부터 선택되고, DR5에 특이적으로 결합하는 본 발명의 항체는 TRAIL-민감성 암세포뿐만 아니라 TRAIL-저항성 암세포에서도 DR5를 통한 자식작용에 의한 세포사멸 (autophagic cell death)을 유도하므로, 다양한 암의 예방 또는 치료에 사용될 수 있다.
