Black chokeberry (Aronia melanocarpa) has been suggested to exert antioxidant and anti-inflammatory effects due to its high polyphenol content. However, the mechanisms underlying the effects of black chokeberry on the alterations of nuclear factor E2-related factor 2 (NRF2) and nuclear factor ;...

nuclear factor E2-related factor 2(NRF2)의 역할은 무엇인가? | 체내 항산화 효소 및 해독 관련 효소를 조절하는 전사인 자인 nuclear factor E2-related factor 2 (NRF2)는 antioxidant response element (ARE)에 결합한 후 세포 보호 유전자(cytoprotective gene), 해독 관련 효소 및 항산화 효소의 발현을 증가시킨 다(Giudice 등, 2010). 전사인자 NRF2는 산화적 스트레스에 대한 보호 기전에 중요한 역할을 할 뿐 만 아니라, 최근 대식세포 내 에 염증 관련 전사인자인 nuclear factor κB (NF-κB)의 활성화에 따른 염증 반응을 저하하는 것으로 알려졌다(Ding 등, 2019; Ren 등, 2020). | |
블랙 초크베리란 무엇인가? | 블랙 초크베리(Black chokeberry)의 학명은 아로니아(Aronia melanocarpa)로 북아메리카의 지역에서 자생하는 베리류다. 폴란드 를 포함한 동유럽에서 많이 재배 생산되고, 최근 우리나라에서는 아로니아로 각광받고 있어 소득 증대 작물로서 재배 농가도 증 가하고 있다(Jurikova 등, 2017). | |
산화적 스트레스를 받으면 체내에서 일어나는 면역 반응은 무엇인가? | 그러나 세포 내 스트레스 및 염증 반응에 의하여 다량으로 생성 된 ROS와 이를 제거하는 체내 항산화 시스템이 불균형을 이루 게 되면 산화적 스트레스를 야기하게 된다(Karunakaran과 Park, 2013). 체내 항산화 효소 및 해독 관련 효소를 조절하는 전사인 자인 nuclear factor E2-related factor 2 (NRF2)는 antioxidant response element (ARE)에 결합한 후 세포 보호 유전자(cytoprotective gene), 해독 관련 효소 및 항산화 효소의 발현을 증가시킨 다(Giudice 등, 2010). 전사인자 NRF2는 산화적 스트레스에 대한 보호 기전에 중요한 역할을 할 뿐 만 아니라, 최근 대식세포 내 에 염증 관련 전사인자인 nuclear factor κB (NF-κB)의 활성화에 따른 염증 반응을 저하하는 것으로 알려졌다(Ding 등, 2019; Ren 등, 2020). |
