연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract AI-Helper 아이콘AI-Helper

The life history of man is summarized as a birth-aging-disease-death. Man eventually ages and dies. How long can humans live? What is aging? Why do we age? Is aging inevitable? Can we rejuvenate? Recent researches on biological aging suggest that humans might overcome aging and rejuvenate. In this p...

문제 정의

  • 우리 실험실에서는 세포의 노화를 억제하거나, 노화세포를 젊은 세포로 회춘시킬 수 있는 물질을 찾는 연구를 수행하였다. 800종의 생약추출물과 이로부터 분리한 200종의 단일성분을 대상으로 조사한 결과, epifriedelanol, quercetin-3-O-β-D-glucuronide, (-)-loliolide, juglanin 등 13종의 단일성분들이 세포수준에서 노화를 억제함을 확인하였다[77-80].

질의응답

핵심어 질문 논문에서 추출한 답변
노화의 과정이 갖는 특징은 무엇인가? “늙는다”는 것, 노화란 무엇인가? 노화란 나이가 들면서 신체기능이 떨어지고, 사망률과 질병에 대한 감수성이 증가하는 과정이다[1,2]. 그러면 노화는 단순히 나이가 들면서 생기는 자연스런 현상인가? 같은 나이라도 사람에 따라 노화의 정도는 다르며, 빨리 늙는 질환, 대표적으로 Werner syndrome, Hudchinson-Gilford syndrome 등도 있다[3].
복제노화가 생기는 원인은 무엇인가? Hayflick과 Moorhead는 복제노화는 조직과 개체노화에 기여하며, 암을 억제하는 내부 방어기전일 것이라고 제시하였다. 복제노화는 진핵세포 DNA가 선형구조이기 때문에 생기는 DNA 말단 복제 문제 때문에 생긴다[23]. 염색체가 분열하는 과정에서 염색체 말단의 텔로미어(telomere)가 점점 짧아지기 때문이다[24].
Hayflick과 Moorhead는 세포노화 현상을 어떻게 발견하였는가? 그럼 개체만 늙는가? 개체를 구성하는 세포는 늙지 않는가? “세포가 늙는다”는 현상, 세포노화 현상은 1961년 Hayflick과 Moorhead가 처음 보고하였다[22]. 사람의 정상 섬유아세포를 분리하여 배양접시에서 배양하면 일정횟수 분열한 후,더 이상 분열하지 않는 현상을 발견한 것이다. 이러한 현상을 복제노화라고 하였으며, 정상 체세포의 분열횟수에 제한이 있는 현상을 발견한 사람의 이름을 붙여 헤이플릭 한계(Hayflick limit)라고 한다.
