De mest kritiska steg i byggandet av HMEJ givare plasmider är: (1) val av sgRNA med hög DNA klyvning effektivitet och låga avståndet mellan sgRNA skärande webbplats och stop kodon, och (2) korrekt uppförande av HMEJ givare. CRISPR/Cas9-medierad klyvning på båda transgenens givare vektor (innehållande sgRNA inriktade på områden och ~ 800 bp homologi armar) och riktade genomet är nödvändiga för effektiv och exakt riktade integration invivo. De mest kritiska steg av generation av inpressning möss me...

Exakt, riktade gen editering krävs ofta för att producera genetiskt modifierade djurmodeller och kliniska behandlingar. Mycket arbete har gjorts för att utveckla olika strategier för effektiv riktad genomet redigering, såsom zink finger nukleotid (ZFN), transkription aktivator-liknande effektor nukleaser (TALENs), och CRISPR/Cas9-system. Dessa strategier skapa riktade DNA dubbel-strand raster (DSB) i genomet och utnyttja inneboende DNA reparation system, såsom homolog rekombination (HR)1,2, microhomology-medierad slutet att gå (MMEJ)3 , 4 , 5, och icke-homolog slutet att gå (NHEJ)6,7,8 för att inducera riktade integration av transgener1,9. HR-baserade strategin är för närvarande den vanligaste genomet redigering tillvägagångssätt som är mycket effektiv i cellinjer, men inte lättillgängliga för icke-dela celler på grund av dess begränsade förekomst i den sena S/G2-fasen. HR-baserade strategin gäller således inte för i vivo gen editering. Nyligen, den NHEJ-baserade strategin utvecklades för effektiv gen knock-in i musen vävnader8. Metoden NHEJ-baserade införs dock vanligtvis indels knytpunkter, vilket gör det svårt att generera exakt gen editering, särskilt när man försöker konstruera i-frame fusion gener8. MMEJ-baserade riktade integration kan exakt gen editering. Men ökar det bara blygsamt riktade integration effektiviteten i tidigare rapporter5. Förbättring av exakt riktade integration i vivo effektivitet behövs därför snarast för breda terapeutiska tillämpningar3.
I ett nyligen publicerat arbete, vi visat en homologi-medierad slutet att gå (HMEJ)-baserat strategi, som visade den högsta riktade integration effektiviteten i alla rapporterade strategier både in vitro- och in-vivo10. Här beskriver vi ett protokoll för etableringen av det HMEJ systemet, och även byggandet av singel-guide RNA (sgRNA) vektorerna inriktning genen av intresse och givaren vektorer hysande sgRNA inriktade på områden och ~ 800 bp homologi vapen (figur 1) . I detta protokoll beskriver vi också de detaljerade anvisningarna för generering av DNA inpressning möss och korta steg för riktade integration i vävnader i vivo. Dessutom visat en proof-of-concept studie av HMEJ-baserade strategi sin förmåga att korrigera Fah mutation och rädda Fah- / - leversjukdom misslyckande möss, vilket ytterligare avslöjade dess terapeutiska potential.

crispr/cas9-mediated targeted integration in vivo using a homology-mediated end joining-based strategy

Som en lovande genomet redigering plattform har CRISPR/Cas9 systemet stor potential för effektiv genmanipulation, särskilt för riktade integration av transgener. På grund av den låga verkningsgraden för homolog rekombination (HR) och olika ditsatta mutationer av icke-homolog slutet att gå (NHEJ)-baserade strategier i icke-dela celler, i vivo genomet redigering fortfarande en stor utmaning. Här, vi beskriver en homologi-medierad slutet att gå (HMEJ)-baserade CRISPR/Cas9-system för effektiv i vivo exakt riktade integration. I detta system, riktade genomet och givaren vektor innehållande homologi armar (~ 800 bp) flankerad av samma guide RNA (sgRNA) mål sekvenser klyvs av CRISPR/Cas9. Denna HMEJ-baserade strategi uppnår effektiva transgenens integration i mus zygoter, liksom i hepatocyter i vivo. Dessutom en HMEJ-baserad strategi erbjuder en effektiv metod för korrigering av fumarylacetoacetathydrolas hydrolas (Fah) mutation i hepatocyterna och räddar Fah-brist inducerad leversvikt möss. Sammantaget med fokus på riktade integration, denna HMEJ-baserade strategi ger ett lovande verktyg för en mängd applikationer, inklusive generationen genmodifierade djurmodeller och riktade genterapi.

HMEJ-baserade gen editering i musembryon: För att definiera inpressning effektiviteten i metoden HMEJ-baserat i mus zygoter, levererat vi Cas9 mRNA, sgRNA inriktning Cdx2 genen och HMEJ givaren in i musen zygoter, som var avsedd att smälta en p2A-mCherry reporter gen till den sista kodon av Cdx2 gen (figur 2A). De injicerade zygoter utvecklats till blastocyster i kulturen. Utvärdera effektiviteten inpress...

CRISPR/Cas9-mediated Targeted Integration In Vivo Using a Homology-mediated End Joining-based Strategy

Den klustrade regelbundet mellanliggande kort palindromic repetitioner/CRISPR associerade protein 9 (CRISPR/Cas9) systemet ger ett lovande verktyg för genteknik och öppnar upp möjligheten att riktade integration av transgener. Vi beskriver en homologi-medierad slutet att gå (HMEJ)-baserat strategi för effektiv DNA riktade integration i vivo och riktade genterapi med hjälp av CRISPR/Cas9.
