Abstract
Description
도 2: log10 변환 후 엘로티닙 하이드로클로라이드의 조정된 p-값 대 제피티닙의 조정된 p-값이 나타나 있다(선은 5%의 오차 가능성을 나타낸다). 영역 A는 엘로티닙 하이드로클로라이드 및 제피티닙에 유의하게 결합하는 단백질을 나타내고, 영역 B 및 C는 각각 엘로티닙 하이드로클로라이드 및 제피티닙에 유의하게 결합하는 단백질을 나타낸다. 영역 D의 단백질은 둘 다에 대해 유의한 결합을 나타내지 않는다. 본 도면은 두 화합물에서 식별된 단백질만 보여줄 수 있으며, 이러한 이유로 엘로티닙 하이드로클로라이드 또는 제피티닙 대체된 샘플에만 존재하는 상기 명명된 단백질은 여기에 나타나 있지 않다.
도 3: 다양한 NSCLC 세포주에서의 엘로티닙 하이드로클로라이드와 제피티닙의 상호작용 프로파일. EGFR의 상대량은 모든 세포주에서 유사한 반면, 본 도면은 엘로티닙 하이드로클로라이드 결합된 분획에서의 ILK, 알파-파빈 및 PINCH의 특정한 풍부함을 보여준다.
도 4: 엘로티닙 및 제피티닙과 ILK DFG-루프 부분과의 잠재적 상호작용을 보여주는 정렬되고 겹쳐진 ILK 및 EGFR 결정 단백질 구조의 ATP 결합 부위. 산소 원자는 붉은색이고, 질소는 파란색이고, 염소는 녹색이고, 불소는 밝은 청록색이다. 엘로티닙/EGFR 복합체(1M17)의 탄소 원자는 연어 색이고, 제피티닙/EGFR 복합체(2ITY)의 탄소 원자는 노란색이고, ILK의 탄소 원자는 흰색이다. 그림은 파이몰(pyMOL)을 사용하여 만들었다. 엘로티닙 및 제피티닙의 아닐린 고리에서 상이한 치환이 존재한다(제피티닙에서는 3 위치가 염소로 치환되었지만 엘로티닙에서는 아세틸렌으로 치환되었고, 엘로티닙에서는 4 위치가 비치환되었지만 제피티닙에서는 불소로 치환되었다). 원자 근접성에서 생성된 차이는 제피티닙에 비해 엘로티닙이 ILK의 ATP 결합 부위에 더 호의적으로 결합하는 것을 암시한다.
도 5: 엘로티닙은 E-카데린을 안정화시킴으로써 H358의 전이를 늦춘다. (A) E-카데린에 대한 웨스턴 블랏. 총 단백질 함량에 대해 정규화되고 2개의 분리된 실험 사이에서 평균화된 (B) E-카데린, (C) ILK 및 (D) PINCH의 정량화된 신호.
도 6: NSCLC 세포주에서의 IPP 발현. (A) EGFR 야생형 NSCLC 상피 세포주 H292, H441, H358, H322, 및 중간엽 세포주 H460, H1299, H226 및 Calu6에 대한 ILK, 알파-파빈, PINCH, E-카데린, 비멘틴 및 GAPDH의 웨스턴 블랏. (B) GAPDH 수준에 대해 정규화되고 IPP 복합체의 발현 수준을 측정하기 위해 평균화된, 정량화된 웨스턴 블랏 신호.
도 7: 임상적 이득을 얻은 환자 대 얻지 못한 환자에서의 E-카데린(CDH1) 및 ILK 발현. 각각의 점은 하나의 샘플에서 측정된 (log2 변환된) 유전자의 신호를 나타낸다. 파란색 및 빨간색 점은 각각 임상적 이득을 얻은 환자 및 얻지 못한 환자의 샘플과 상응한다(돗플롯을 파테크(Partek) 소프트웨어를 사용하여 수행하였다).
