Abstract:
PURPOSE: A biomarker for diagnosing resistance to a chemotherapeutic agent in a patient with breast cancer is provided to enable an individual patient to select a treatment direction and to enhance survival rate of the patient without recurrence. CONSTITUTION: A composition for diagnosing resistance to a chemotherapeutic agent in a patient with breast cancer contains antibodies which specifically bind to proteins selected among a group consisting of alpha-2-HS-glycoprotein, apolipoprotein B, complement component 3, complement component 9, ceruloplasmin, and orosomucoid 1. A kit for diagnosing resistance to a chemotherapeutic agent contains the antibodies. A microarray for diagnosing resistance to a chemotherapeutic agent contains the antibodies.
Abstract:
본 발명은 혈청 단백질로부터 분리한 유방암 환자의 화학요법제 저항성 진단용 바이오마커에 관한 것으로, 보다 상세하게는 화학요법제 민감성 환자와 내성 환자 사이에서 차별화되게 발현되는 단백질에 특이적인 항체를 포함하는 유방암 환자의 화학요법제 저항성 진단용 조성물 및 상기 단백질을 암호화하는 핵산에 특이적인 프라이머 또는 프로브를 포함하는 유방암 환자의 화학요법제 저항성 진단용 조성물에 관한 것이다. 본 발명의 유방암 환자의 화학요법제 저항성 진단용 바이오마커는 유방암 환자의 화학요법제 저항성 진단하여 개별 환자에게 치료 방향의 선택권을 부여하고, 더 나아가 유방암 환자의 무재발 생존율을 높일 수 있다.
Abstract:
PURPOSE: A marker for diagnosing lung cancer is provided to accurately and early diagnose adenocarcinoma(ACC) and squamous cell carcinoma(SCC). CONSTITUTION: A biological method for selecting a marker which is able to diagnose lung cancer and lung cancer sub-type from the blood comprises: a step of preparing data of ACC(adenoaricinoma) and SCC(squamoous cell carcinoma) among non-small cell lung cancer(NSCLC) from a reference; a step of selecting a gene having expression level difference between ACC and SCC and expression level difference between SCC and novel lung cells; a step of selecting a gene which is specifically expressed in the lung among the marker gene candidates; a step of selecting a protein which is possibly secreted from the blood among the marker genes; a step of constructing a network model using the protein and selecting a marker which is able to diagnose lung cancer and lung cancer subtype; and a step of verifying the candidate using an ELISA system.
