We investigated the effect of red cabbage extract (RCE) on cell death in MDA-MB-231 human breast cancer cells. Cells were cultured in the presence 1.0, 1.5, and 2.0 mg/mL concentrations of RCE for 24 hours. MTT assays demonstrated that mitochondrial dehydrogenase activities decreased in a dose-depen...

세포사멸이란 무엇인가? | 세포사멸(apoptosis)은 계획된 세포죽음(programmed cell death)으로 발생단계나 DNA 손상, 바이러스 감염 등에 의한 유전적 조절 하에서 일어나는 정교한 인체 방어 메커니즘이라는 점에서 세포괴사(necrosis)와 구별되어지는데 세포 분열과 함께 정상 조직 괴사의 조절과 유지에 중요한 역할을 하며 세포의 항상성을 유지하기도 한다(5,6). 세포사멸을 결정하는데 여러 가지 요인이 작용을 하는데 그중에서도 Bcl-2 family가 중요한 역할을 수행한다. | |
적양배추에 함유된 암 진행 과정에 관여하는 효소 작용을 차단하는 성분은? | Brassica species에 속하는 적양배추는 흰색 양배추보다는 과당과 포도당, 라이신, 비타민 C 등의 영양 성분이 더 많고 또한 셀레늄이 풍부하다(9). 적양배추는 indole-3-carbinol(I3C)를 함유하며 이는 암이 빠르게 진행되는 과정에 관여하는 효소의 작용을 차단하는 기능이 있다는 사실이 발견되었다(10). 특히 적양배추의 붉은색을 내는 성분인 flavonoid류 중 anthocyanin은 항산화 효능이 뛰어나서 암세포 증식을 억제하고 세포의 염증 반응을 줄이며, free radical에 의한 세포손상을 막아 준다(11,12). | |
적양배추 추출물의 항유방암 효과를 검정하기 위한 세포사멸 및 ROS를 측정한 결과, 추출물 농도와의 상관관계는? | 05). 또한 세포사멸/괴사 분석(Hoechst33342/ethidium bromide 염색법), flow cytometry assay, ROS 측정(DCF-DA 염색법) 등의 세포 화학적 방법을 통해 분석한 결과 처리 농도가 증가할수록 세포사멸이 유의적으로 증가하였고, ROS 생성 또한 증가하였다. 특히 2. |
