Gen levering i levende gnagere av electroporation er ofte brukt i nevrobiologi felt17,18,19,20,21. Dens potensielle anvendelser i mange andre organer har ikke vært mye utforsket.

Genmodifiserte musen modeller (GEMMs) har spilt en viktig rolle i å utvide vår kunnskap om animalske utvikling, gene funksjoner i vivoog mekanismer for sykdom progresjon1,2. Germline GEMMs er tradisjonelt utviklet på to måter. Først er etableringen av transgene mus ved pronuclear injeksjon av DNA plasmider etterfulgt av transplantasjon av zygotes i pseudopregnant kvinner. Den andre er generasjonen av knock-out/knock-i mus av homologe rekombinasjon i embryonale stamceller og utvikling av chimeras. Betinget knockout av gener i bestemte vev eller celle type interesse innebærer oppdrett av genmodifiserte alleler med grobunn og flox i flere generasjoner. Hele prosessen kan være dyrt og tidkrevende, særlig hvis målet er å målrette flere gener vev-spesielt. Nylig, gen-redigering teknologier som gruppert regelmessig interspaced kort palindromic gjentar (CRISPR) er brukt på flere organer av mus å indusere vev-spesifikke genetiske endringer for autochtonous kreft modellering3, 4,5,6,7 eller riktig sykdom mutasjoner i situ8,9. I disse studiene, var levering av gRNA vektorer vanligvis oppnås gjennom adenoviral eller lentiviral infeksjoner av orgel eller etter halen blodåre injeksjon. Det er relative enkelt for levering av CRISPR komponenter til lunge og lever har kraftig forbedret bekvemmeligheten og effektiviteten av kreft modellering i disse organene sammenlignet med de tradisjonelle grobunn-Lox basert musen modellene.
Blæren urothelium er der de fleste blæren svulster stammer. Levering av DNA vektorer til blære urothelium for kreft modellering eller gene terapi er hindret av et glycosaminoglycan på apikale urothelial overflaten, som fungerer som en barriere for tilslutning smittsomme virus10,11. Flere forbehandling agenter som Syn3 og dodecyl-β-d-maltoside har blitt brukt til å avbryte denne barrieren og forbedre adenovirus, infeksjon, effektivitet,12,,13,,14. Om adeno-assosiert virus (AAVs) effektivt kan infisere blæren er ikke rapportert. Overall, en ikke-viral basert leveringsmetode ville være ønskelig. Her beskriver vi en ny metode utviklet i laboratoriet for effektiv DNA plasmider levering til musen urothelium gjennom urinrøret catheterization og electroporation. Fordi vår tilnærming ikke innebærer kjemisk forbehandling av glycosaminoglycan laget eller virus produksjon, det betydelig forenkler levering av DNA plasmider i musen blæren urothelium, og skal lette ulike i vivo studier blæren sykdommer.

novel method of plasmid dna delivery to mouse bladder urothelium by electroporation

Genmodifiserte musen modeller (GEMMs) er svært verdifull i avslørende romanen biologiske innsikt i initiering og progresjon mekanismer av menneskelige sykdommer som kreft. Transgene og betinget knockout mus er ofte brukt for gene overuttrykte eller ablasjon i bestemte vev eller cellen typer i vivo. Men kan germline musen modeller være tidkrevende og kostbare. Siste fremskritt i genet teknologier og muligheten for å levere DNA plasmider ved virusinfeksjon har aktivert rask generasjonen non-germline autochtonous musen kreft modeller for flere organer. Blæren er et organ som har vært vanskelig for viral vektorer til av et glycosaminoglycan lag som dekker urothelium. Her beskriver vi en ny metode utviklet i laboratoriet for effektiv levering av DNA plasmider i musen blæren urothelium i vivo. Gjennom intravesical instillasjon av pCAG-GFP DNA plasmider og electroporation av kirurgisk eksponert blæren viser vi at DNA plasmider leveres spesielt i blæren urothelial celler for forbigående uttrykk. Vår metode gir en rask og enkel måte for overuttrykte og knockdown av gener i musen blæren, og kan brukes til å bygge GEMMs for blærekreft og andre Urologiske sykdommer.

For å demonstrere suksess gen levering i blæren urothelium, brukte vi pCAG-GFP15 plasmider for electroporation. 20 µL av plasmider og Trypan blå løsning ble injisert gjennom urinrøret og 5 elektriske pulser ble administrert. Etter 48 timer, vi dissekert musen blæren og observert flekker av GFP fluorescens under disseksjon fluorescens mikroskop, mens en negativ kontrollerer blæren som ikke gjennomførte electroporation viste ingen GFP signal (<strong class="...
