I denne protokollen detalj vi alle trinnene som er nødvendig for å oppnå i vivo cardiac genet redigering i postnatal mus ved hjelp av rAAVrh.74-mediert levering av SaCas9 og to gRNAs. Som tidligere nevnt, denne tilnærmingen kan brukes til å gjenopprette dystrophin uttrykk i dystrophic mus som beskrevet i våre arbeid27, men det kan også aktivere rask omvendt genetikk studier av hjerte-relaterte gener i mus uten den omstendelige prosessen med den tradisjonelle knockout tilnærming ti...

Gruppert, regelmessig interspaced, korte palindromic gjenta (CRISPR) teknologien representerer det nyeste fremskrittet i genomet engineering og har revolusjonert dagens praksis med genetikk i celler og organismer. CRISPR-baserte genomet redigering benytter en enkelt hjelpelinje RNA (gRNA) slik at en CRISPR-assosiert endonuclease som CRISPR-assosiert protein 9 (Cas9) og Cpf1 til et genomisk DNA-mål som er komplementære i rekkefølge til protospacer kodet av gRNA med en bestemt protospacer tilstøtende motiv (PAM)1,2. PAM varierer avhengig av bakteriell artene av Cas9 eller Cpf1 genet. Den mest brukte Cas9 nuclease avledet fra Streptococcus pyogenes (SpCas9) gjenkjenner en PAM sekvens av NGG som finnes direkte nedstrøms mål sekvensen i genomisk DNA, på den ikke-mål stranden. På målområdet generere Cas9 og Cpf1 proteiner en dobbel-strand pause (DSB), som deretter repareres via iboende cellulære DNA reparasjon mekanismer inkludert ikke-homologe slutten med (NHEJ) og homologi-rettet reparasjon (HDR) veier3, 4. I fravær av en DNA mal for homologe rekombinasjon, er DSB primært reparert av feilutsatte NHEJ veien, som kan resultere i innsettinger eller slettinger (indeler) av nukleotider forårsaker frameshift mutasjoner hvis DSB ble opprettet i koding regionen et gen5,6. Dermed har CRISPR systemet vært mye brukt til ingeniør tap-av-funksjon mutasjoner i ulike mobilnettet modeller og hele organismer, for å undersøke funksjonen av et gen. Videre katalytisk inaktive Cas9 og Cpf1 har blitt utviklet til transcriptionally og modulerer epigenetically uttrykk for målet gener7,8.
Flere nylig, både SpCas9 og SaCas9 (avledet fra Staphylococcus aureus) har blitt pakket i rekombinant adeno-assosiert virus (rAAV) vektorer for postnatal genet korreksjon i dyr modell av menneskelige sykdommer, særlig Duchenne muskeldystrofi (DMD)9,10,11,12,13,14,15. DMD er en dødelig X-tilknyttet recessiv sykdom forårsaket av mutasjoner i genet DMD , som koder dystrophin proteiner16,17, påvirker ca ett i 3500 mann fødsler ifølge nyfødt screening18 , 19. det er preget av progressiv muskelsvakhet og sløse. DMD pasienter mister vanligvis evnen til å gå mellom 10 og 12 år og dø av luftveiene og/eller hjerte svikt av 20-30 årene20år. Spesielt kardiomyopati utvikler i > 90% av DMD pasienter og representerer ledende årsak til død i DMD pasienter21,22. Selv om Deflazacort (en anti-betennelse stoff) og Eteplirsen (en ekson hoppe medisin for hoppe ekson 51) har nylig godkjent for DMD av Food and Drug Administration (FDA)23,24, ingen av disse behandlingene korrigere den genetisk defekten på genomisk DNA-nivå. Mdx musen, som bærer en punkt mutasjon på ekson 23 av dystrophin genet, har vært mye brukt som en DMD modell25. Videre har vi tidligere viste at funksjonelle dystrophin uttrykket ble restaurert av-ramme sletting av genomisk DNA dekker exons 21, 22 og 23 i skjelettmuskulatur mdx mus ved hjelp av intramuscular Ad-SpCas9/gRNA levering9 , og i hjertet muskler mdx/utrophin+ /- mus ved hjelp av intravenøs og intraperitoneal rAAVrh.74-SaCas9/gRNA levering26.
I denne protokollen beskrive vi i detalj alle trinn i postnatal cardiac genet redigering for å gjenopprette dystrophin i mdx/utrophin+ /- mus ved hjelp av rAAVrh.74-SaCas9/gRNA vektorer, fra gRNA design dystrophin analyser i delene hjertet muskel.

Gruppert, regelmessig interspaced, kort, palindromic gjenta (CRISPR) systemet har mye lettere genomet engineering i både kulturperler celler og levende organismer fra et bredt utvalg av arter. CRISPR teknologien har blitt utforsket som roman legemiddelselskap for en rekke menneskelige sykdommer. Proof-of-concept data er svært oppmuntrende som eksemplifisert ved studier som viser den gjennomførbarhet og effekten av genet redigering terapeutisk tilnærming for Duchenne muskeldystrofi (DMD) bruker en murine modell. Spesielt har intravenøs og intraperitoneal injeksjon av rekombinant adeno-assosiert virus (rAAV) serotype rh.74 (rAAVrh.74) aktivert effektiv cardiac levering av Staphylococcus aureus CRISPR-assosiert protein 9 (SaCas9) og to Guide RNAs (gRNA) for å slette en genomisk region med en mutant codon i ekson 23 av musen Dmd genet. Denne samme tilnærming kan også brukes til å slå ut den gen-av-begrave og studere deres hjertefunksjon i postnatal mus når gRNA er utformet for å målrette den gen-regionen av genet. I denne protokollen viser vi i detalj hvordan ingeniør rAAVrh.74 CRISPR vektor og oppnå svært effektiv cardiac levering i neonatal mus.

Effekten av gRNAs å indusere sletting av målregion genomisk DNA bør vurderes i cellekulturer før emballasje i rAAV for i vivo studier. Dette gRNAs og SaCas9-uttrykke konstruksjoner var electroporated i C2C12 celler og genomisk DNA ble analysert av PCR med primerne flankert målområder (figur 1). Et PCR produkt av ~ 500 bp indikerer vellykket sletting av målet genomisk DNA fra gene redigering mens kontroll cellene ikke bør gi et band på grunn av den st...

Adeno-Associated Virus-Mediated Delivery of CRISPR for Cardiac Gene Editing in Mice

Her vi gir en detaljert protokoll til å utføre i vivo cardiac genet redigering i mus ved hjelp av rekombinant Adeno-Associated Virus (rAAV)-mediert levering av CRISPR. Denne protokollen tilbyr en lovende terapeutiske strategi for å behandle dystrophic kardiomyopati i Duchenne muskeldystrofi og kan brukes til å generere hjerte-spesifikke knockout i postnatal mus.
