Her beskriver vi en allment tilgjengelig metode å integrere stabilt en GOI genomet av målcellene av Tornerose-mediert transponering. Selv om den SB-systemet ble utviklet for å gi en nonviral metode for genomet redigering, er effektiv levering av integrasjon maskiner (transposase og T2 transposon) obligatorisk. Derfor for å bruke SB-systemet på knapt transfectable primære celler, ble en viral levering av SB komponenter forfulgt i årene10,12,</...

Den hyperaktiv SB100X transposase koblet til T2-baserte transposon er allerede brukt i preklinisk gene terapi programmer1,2,3genom endringene4,5, og indusert pluripotent stilk cellen (iPSC) omprogrammering6,7. Vanligvis SB komponentene leveres transiently av plasmider transfection og en sterk konstituerende promoter stasjoner uttrykk for transposase. Men til tross for forbedret nye metoder for hva, levering av to-komponent er fortsatt en utfordring for mange programmer. Dermed har utviklingen av en ny levering protokoll økende interesse. Foruten transfection metoder for plasmider8 og mRNA9, viral levering basert på adenoviral10,11, adeno-assosiert virus (AAV)12, Baculovirus13, gammaretroviral14 og lentiviral vektorer15 har blitt foreslått i fortiden. Spesielt, må system av valget garantere en forbigående levering av SB komponenter uten integrering av viral vektoren. Likevel øker grunnleggende uttrykk for transposase sikkerheten bekymringer på grunn av risken ukontrollerbare rehopping av transposon.
Derfor er transcriptional regulering av SB100X av raffinerte Tet-ON den første utfordringen. En modifisert Tet-responsive promoter, ved å erstatte opprinnelige utviklet minimal cytomegalovirus (CMV) selskapet med minimal arrangøren (-81) av Timidine Kinase (TK) genet Herpes Simplex Virus-1 (HSV-1)16, er klonet over den SB100X cDNA (pTetOTKSB100X). Den muterte omvendt-tetracycline-transactivator rtTA2s-M217 uttrykkes under kontroll av sterk konstituerende selskapet (phosphoglycerate promoter, PGK) klonet i en annen plasmider (pCCL-PGKrtTA2S-M2). Når lagt til kultur medium, dox binder rtTA2s-M2 modulator og tethers Tet arrangøren komplekse eller, resulterer i strengt regulert induksjon av SB100X uttrykk18.
Den andre store utfordringen oppstår fra den ineffektive transfection av menneskelige primære celler av flere fysiske og kjemiske metoder. Effektivt levere transposase i menneskeceller motstandsdyktig mot transfection, SB100X og rtTA2s-M2 uttrykk kassetter er pakket inn i to integrasjon defekt lentiviral vektorer (IDLVs)19: IDLVTKSB og IDLVrtTA2s- M2. Viral vektorer produseres transiently som tredje generasjon vektorer i HEK293T celler20 og pseudotyped med glykoprotein G av Vescicular stomatitt viruset (VSV-G), som gir et bredt spekter av infeksjon. Vector partikler er konsentrert av ultracentrifugation og titreres med HIV-1 kneble p24 immunocapture. For å transduce linjer og primære celler, vektor partikler er kompleksbundet med polybrene og er ruges med målcellene i tilstedeværelse eller fravær av dox. Narkotikaavhengige aktivering av SB100X uttrykk i transduced celler er målt ved kvantitative RT PCR (qRT-PCR)18.
Når Tet regulert SB100X uttrykk er bevist, følger transponering av GOI (f.eks grønt fluorescerende protein, GFP) i målet cellen genomet molekylære hendelsene tydelig schematized av Bak og Mikkelsen21. En tredje IDLV vektor bærer et uttrykk kassett for GOI klonet mellom T2-transposon IRs (IDLVT2) har bygget og pakket som nevnt ovenfor. Endelig, tre IDLV vektorer kan brukes til å effektivt transduce menneskelige celler (f.eks primære keratinocytter) i vitro og integrere GOI i nærvær av doxycycline18.

an efficient in vitro transposition method by a transcriptionally regulated sleeping beauty system packaged into an integration defective lentiviral vector

Sleeping Beauty (SB) transposon er en ikke-viral integrere med påvist effekt for genoverføring og funksjonell genomforskning. For å optimalisere SB transposon maskiner, er en transcriptionally regulert hyperaktiv transposase (SB100X) og T2-baserte transposon ansatt. Vanligvis, transposase og transposon tilbys transiently av plasmider transfection og SB100X uttrykk er drevet av en konstituerende promoter. Her beskriver vi en effektiv metode for å levere SB komponentene til menneskelige celler som er motstandsdyktig mot flere fysiske og kjemiske transfection metoder, til å kontrollere SB100X uttrykk og stabilt integrere en genet av interesse (GOI) gjennom en "klippe og lime" SB mekanisme. Uttrykk for hyperaktiv transposase er strengt kontrollert av Tet-på systemet, mye brukt til å kontrollere genuttrykk siden 1992. Genet av interesse er flankert av invertert gjentar (IR) av T2 transposon. Begge SB komponentene pakkes i integrering defekt lentiviral vektorer transiently produsert i HEK293T celler. Menneskelige celler, linjer eller primære celler fra menneskelig vev, er i vitro transiently transduced med viral vektorer. Ved tillegg av doxycycline (dox, tetracycline analog) til kultur medium, en finjustering av transposase uttrykk måles og resulterer i en varige integrasjon av genet av interesse i genomet av behandlet cellene. Denne metoden er effektiv og celle linje (f.eks HeLa celler) og primære keratinocytter (f.eks menneskelige primære), og dermed representerer et verdifullt verktøy for genteknologi og terapeutiske genoverføring.

Bruke fremgangsmåten presenteres her, tre IDLV vektorer bærer regulert SB komponentene (SB100X, rtTA2S-M2 og T2-GFP transposon) var pakket og brukes til å effektivt levere og tett regulere SB systemet i menneskeceller. Figur 1A viser en plan for i vitro signaltransduksjon HeLa celler, som ble utført for å evaluere transcriptional regulering av SB transposase med beste dose kombinasjon av to IDLV vektorer (rapportert i tabell 2...
