이 방법의중요성은 드로소필라 배아21,22, 23,24,25,26, 27에서 미세 주입의 잘 확립 된 프로토콜을 활용하여 ASR 및 동반 액틴 로드 조립에 관한 새로운 연구를 가능하게한다는 것입니다. 살아있는 배아에 G-actinRed를</...

이 프로토콜은 유도할 수 없는 액틴 응력 반응(ASR)1을겪고 있는 열 응력 배아에서 핵액틴 봉의 조립을 시각화하기 위해 G-actinRed를 주입하는 방법을 설명합니다. 우리는 배아에서 성기능 장애를 일으키고 생존력을 감소시키는 ASR의 연구를 돕기 위해 이 프로토콜을 개발했으며, 성인 인간 세포 유형은 신부전2,근육 근병증3,알츠하이머 및 헌팅턴병4,5,6,7,8을포함한 병리와 관련이 있다. 이러한 ASR은 열 충격9,10,11,산화 스트레스4,6,감소된 ATP 합성12,비정상적인 헌팅틴 또는 β-아밀로이드 올리고머화4,5,6,7,9,13,14, 15,16을포함한 수많은 세포응력에의해 유도된다. ASR의 특징은 반응하는 세포의 세포질 또는 핵에서 비정상적인 액틴 봉의 조립으로, 이는 작용 단백질, 코필린1,5,6,10의스트레스 유발 과잉 활성화에 의해 구동된다. 안타깝게도 ASR에 대한 주요 지식 격차는 여전히 남아 있습니다. 예를 들어 액틴 로드의 기능은 알려져 있지 않습니다. 우리는 왜 막대가 몇몇 세포 모형의 세포질에서 형성하는지 이해하지 않습니다, 그러나 그 외의 핵. ASR이 스트레스를 받고 있는 세포 또는 배아에 대한 보호또는 적응력이 있는지도 분명하지 않습니다. 마지막으로, 우리는 여전히 Cofilin 하이퍼 활성화 또는 액틴 로드 어셈블리의 기본 상세한 메커니즘을 모른다. 따라서, 이러한 프로토콜은 살아있는 과일 플라이 배아의 고도로 인가가능한 실험 시스템에서 액틴 로드 형성 및 역학을 시각화하여 ASR을 조사하는 신속하고 다재다능한 분석법을 제공한다.
살아있는 Drosophila 배아로 G-actinRed를 마이크로젝트하는 프로토콜은 조직 건물 이벤트 도중17의 일반적인 세포질 액틴 구조물의 역학을 연구하기 위하여 처음에 개발되었습니다. 그 연구 결과에서, 우리는 G-actin적부분이 세포동체증 또는 위화17,18을포함하여 태아의 초기 발달 과정에 부정적인 영향을 미치지 않았다는 것을 것을을 발견했습니다. 그런 다음 프로토콜을 수정하여 ASR1을겪고 있는 열 스트레스 배아에서 액틴 봉의 이미징을 허용하기 위해 배아 처리 및 G-actin적주입을 조정한다. G-actin빨간 주입 외에 다른 방법은 배아에서 액틴을 시각화하는 데 사용할 수 있습니다. 이러한 방법은 유트로핀-mCherry, Lifeact, F-로틴-GFP 및 모에신-GFP(19에서 검토됨)와 같은 액틴 결합 단백질의 영역또는 액틴 결합 단백질의도메인에 태그된 형광 단백질(FPs)을 발현하는 데 의존합니다. 그러나, 이러한 FP 프로브를 사용하면 일부 액틴 구조를 안정화하거나 방해할 수 있기 때문에 주의가 필요하며, 모든 액틴구조(20)를동등하게 라벨화하지 않으며, 액틴-GFP의 경우 스트레스 의존일뿐만 아니라 액틴 농도의존도 1인로드 어셈블리의 분석에 문제가 된다. 따라서, G-actinRed는 플라이 배아에서 막대 연구를 선호하는 프로브이며, 배아의 큰 크기는 쉽게 주입할 수 있다.
이 프로토콜의 워크플로우는 단백질, 핵산, 약물 및 형광 지표를 Drosophila 배아21,22,23,24,25,26,27에주입하는 데 사용되어 온 다른 잘 확립된 미세 주입 기술과 유사합니다. 그러나, 여기서 G-actinRed의 미세 주입에 이어, 배아는 ASR 및 핵내 액틴 로드 조립을 유도하기 위해 온화한 열 응력에 노출된다. 파리와 사출 장비에 접근할 수 있는 실험실의 경우, 이 방법은 ASR과 관련하여 특정 연구 라인에 대해 쉽게 구현가능하고 적응할 수 있어야 하며, 여기에는 다른 스트레스 또는 뚜렷한 유전 적 배경의 변조에 의한 유도가 포함됩니다.

imaging intranuclear actin rods in live heat stressed drosophila embryos

이 프로토콜의 목적은 열 응력에 따라 살아있는 Drosophila 멜라노가스터 배아에서 조립되는 핵 액틴 막대를 시각화하는 것입니다. 액틴 로드는 신경 퇴행성 질환을 포함한 인간의 병리학과 함께 제공되는 보존되고 유도할 수 없는 액틴 스트레스 반응(ASR)의 특징입니다. 이전에, 우리는 ASR이 태아 발달의 형태 발생 실패 및 감소된 생존에 기여한다는 것을 보여주었습니다. 이 프로토콜은 이미징, 유전학 및 생화학에 매우 순종하는 모델 시스템에서 근본적인 actin 막대 조립 및 ASR 메커니즘의 지속적인 연구를 허용합니다. 배아는 주사를 준비하기 위해 커버슬립에 수집되고 장착됩니다. 로다민-컨쥬게이드 구형 액틴(G-actinRed)은희석되어 마이크로니들로 적재된다. 단일 주사는 각 태아의 중심으로 이루어집니다. 주사 후, 배아는 높은 온도에서 배양되고 핵 내 액틴 막대는 공초점 현미경 검사법에 의해 시각화됩니다. 광표백 후형화 회복(FRAP) 실험은 액틴 봉상에서 수행될 수 있다; 및 세포질에 있는 그밖 액틴이 풍부한 구조물은 또한 심상일 수 있습니다. 우리는 G-actin빨간 내인성 G-actin 같이 중합하고, 그 자체로, 일반적인 배아 발달을 방해하지 않는다는 것을 것을을 발견합니다. 이 프로토콜의 한 가지 제한은 태아에 심각한 부상을 피하기 위해 주입 중에주의를 기울여야한다는 것입니다. 그러나, 연습으로, Drosophila 배아에 G-액틴레드를 주입하는 것은 actin 막대를 시각화하는 빠르고 신뢰할 수있는 방법이며, 쉽게 어떤 유전자형의 파리또는 저산소증과 산화 스트레스를 포함한 다른 세포 스트레스의 도입과 함께 사용할 수 있습니다.

배아 처리의 회로도 워크플로우가 도 1에묘사되고, 일반적인 실험을 위한 시간표는 표 1에제시된다. 좋은 실험 결과에 대한 추정은 주입된 10개의 배아마다, 조회된 배아의 적어도 절반은 올바른 발달 단계에 있을 것이고, 손상되지 않고, 32°C에서 열 응력으로 견고한 ASR을 나타낸다는 것입니다. 이러한 ASR은 도 2A(오른쪽 패널)에서 배아의 ?...
