The anticancer activity of a methanolic extract from lemon leaves (MLL) was assessed in MCF-7-SC human breast cancer stem cells. MLL induced apoptosis in MCF-7-SC, as evidenced by increased apoptotic body formation, sub-G1 cell population, annexin V-positive cells, Bax/Bcl-2 ratio, as well as proteo...

Autophagy란? | 세포가 지닌 죽음 수용체에 의해 매개되는 외인성 경로(extrinsic pathway)와 미토콘드리아 매개 내인성 경로(intrinsic pathway)가 있으며, 이러한 경로들을 통해 궁극적으로 caspase들의 활성화에 의해 세포들을 죽음에 이르게 한다. Autophagy는 진화적으로 잘 보존된 기작 중의 하나이며, 리소좀(lysosome)을 통하여 세포 내에서 불필요한 구성물질이나 손상된 세포 소기관들을 분해하는 과정을 말 한다. Autophagy는 autophagosome으로 알려진 이중막 소포체를 형성하고, 성숙되면 lysosome과 융합하여 autophagolysosome 을 형성한다. | |
EMT는 특히 어디에서 많이 발생되는가? | EMT (epithelial-mesenchymal transition)는 정상적 배아발달 과정에서 발생하는 하나의 현상이지만, 암세포에서는 세포의 침윤과 이동에 주요한 과정이며, 전이성 암세포에서 특히 많이 발생된다(Lamouille 등, 2014). 암세포가 EMT 과정을 거치게 되면 섬유모세포와 같은 표현형을 지니게 되며 원래의 epithelial 성질을 잃으면서 세포의 이동이 쉬운 형태로 변하게 된다. | |
두 종류의 apoptosis 경로를 구성하는 것은? | 세포예정사(programed cell death)라고도 불리는 apoptosis는 노화, 항상성 유지, 발달과정에서 일반적으로 발생하며 세포 내에서 두 종류의 apoptosis 경로가 존재한다. 세포가 지닌 죽음 수용체에 의해 매개되는 외인성 경로(extrinsic pathway)와 미토콘드리아 매개 내인성 경로(intrinsic pathway)가 있으며, 이러한 경로들을 통해 궁극적으로 caspase들의 활성화에 의해 세포들을 죽음에 이르게 한다. Autophagy는 진화적으로 잘 보존된 기작 중의 하나이며, 리소좀(lysosome)을 통하여 세포 내에서 불필요한 구성물질이나 손상된 세포 소기관들을 분해하는 과정을 말 한다. |
