Abstract
Description
도 2는 위암세포주인 MKN1 세포를 저산소 조건에서 시간별로 배양한 후 real-time PCR 실험을 통해 microRNA-382의 발현량을 나타낸 것이다. 정상산소 대비 저산소 조건에서 microRNA-382의 발현이 증가함을 확인하였으며 24시간 배양시 microRNA-382가 가장 많이 발현됨을 알 수 있었다.
도 3은 저산소 조건에서 발현이 증가된 microRNA-382를 억제제를 처리하여 감소시킨 조건배지에 혈관내피세포를 배양하였을 때 세포의 증식능이 억제된 결과를 나타낸 것이다.
도 4는 저산소 조건에서 발현이 증가된 microRNA-382를 억제제를 처리하여 감소시킨 조건배지에 혈관내피세포를 배양하였을 때 세포의 이동능이 억제된 결과를 나타낸 것이다.
도 5는 저산소 조건에서 발현이 증가된 microRNA-382를 억제제를 처리하여 감소시킨 조건배지에 혈관내피세포를 배양하였을 때 세포의 혈관 형성능이 억제된 결과를 나타낸 것이다.
도 6은 정상산소 조건에서 microRNA-382의 발현을 증가시킨 조건배지에 혈관내피세포를 배양하였을 때 세포의 증식능이 향상된 결과를 나타낸 것이다.
도 7은 정상산소 조건에서 microRNA-382의 발현을 증가시킨 조건배지에 혈관내피세포를 배양하였을 때 세포의 이동능이 향상된 결과를 나타낸 것이다.
도 8은 정상산소 조건에서 microRNA-382의 발현을 증가시킨 조건배지에 혈관내피세포를 배양하였을 때 세포의 혈관 형성능이 향상된 결과를 나타낸 것이다.
도 9는 저산소 조건의 암 세포에서 PTEN의 발현량이 감소됨을 확인한 결과를 나타낸 것이다.
도 10은 microRNA-382와 PTEN의 3'UTR의 결합 부위를 나타낸 그림이다.
도 11은 microRNA-382와 PTEN 3'-UTR 결합 유무를 확인하기 위해, PTEN의 3'UTR이 포함된 luciferase 단백질이 융합된 형태의 재조합 벡터를 제작하고, 상기 벡터가 형질도입된 세포주에 microRNA-382를 처리한 후, 세포에서 발현되는 luciferase의 활성을 측정하여 나타낸 그래프이다.
도 12는 miroRNA-382에 의한 PTEN 단백질의 발현량 변화를 확인할 결과이다.
도 13은 microRNA-382의 혈관신생촉진 효과를 확인하기 위한, CAM assay를 수행한 결과이다(scale bar=2 mm).
도 14는 PTEN에 의해 microRNA-382의 혈관신생촉진 효과가 억제되는지 확인하기 위해, tube formation assay를 수행한 결과이다.
도 15는 PTEN에 의해 microRNA-382의 혈관신생촉진 효과가 억제되는지 확인하기 위해, CAM assay를 수행한 결과이다.
