Elektroporation øger cellens membran permeabilitet og er en kraftfuld teknologi til gen electrotransfer16. Gen levering i levende gnavere af elektroporation har været hyppigt anvendt i neurobiologi felter17,18,19,20,21. Dens potentielle anvendelser i mange andre organer ikke er blevet grundigt udforsket. Til vores viden er vores metod...

Gensplejsede musemodeller (GEMMs) har spillet en væsentlig rolle i at udvide vores viden om dyrenes udvikling, genet funktioner i vivoog mekanismer af sygdom progression1,2. Genom GEMMs er traditionelt udviklet på to måder. Først er oprettelse af Transgene mus af pronuclear injektion af DNA plasmid efterfulgt af transplantation af zygotes i pseudopregnant kvinder. Den anden er generation af knock-out/knock-i mus af homologe rekombination i embryonale stamceller og udviklingen af kimærer. Betinget knockout af gener i specifikke vævs- eller type af interesse omfatter opdræt af gensplejsede alleler med Cre og flox steder i flere generationer. Hele processen kan være dyrt og tidskrævende, især hvis målet er at målrette flere gener væv-specifikt. For nylig, gen-redigering teknologier såsom grupperet regelmæssigt interspaced korte palindromiske gentagelser (CRISPR) har været anvendt til flere organer af mus til at fremkalde væv-specifikke genetiske ændringer for autokton kræft modellering3, 4,5,6,7 eller korrekte sygdom mutationer i situ8,9. I disse undersøgelser, blev leveringen af gRNA vektorer normalt opnået gennem adenoviral eller lentiviral infektion af orgel eller hydrodynamiske hale-vene injektion. Den relative lethed levering af CRISPR komponenter til lunge og lever har stærkt forbedret den bekvemmelighed og effektivitet af kræft modellering i disse organer, i forhold til de traditionelle Cre-Lox baseret musemodeller.
Blære urothelium er, hvor de fleste blære tumorer stammer. Levering af DNA vektorer til blære urothelium for kræft modellering eller gen terapi er hæmmet af en glykosaminoglykan lag på den apikale urothelial overflade, der fungerer som en barriere for fastholdelse af smitsomme virus10,11. Flere forbehandling agenter såsom Syn3 og dodecyl-β-d-maltoside har været brugt til at forstyrre denne barriere og forbedre adenovirus infektion effektivitet12,13,14. Om adeno-associeret virus (AAVs) effektivt kan inficere blæren er ikke blevet rapporteret. Samlet set ville en ikke-virale baseret leveringsmetode være ønskeligt. Her, vi beskriver en ny metode udviklet i laboratoriet for effektiv DNA plasmid levering til mus urothelium gennem urinrørs-kateteration og elektroporation. Fordi vores tilgang ikke indebærer kemisk forbehandling af glykosaminoglykan lag eller virus produktion, det betydeligt forenkler leveringen af DNA plasmider i mus blære urothelium, og bør lette forskellige i vivo undersøgelser blære sygdomme.

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

Gensplejsede musemodeller (GEMMs) er yderst værdifuldt i afslørende roman biologiske indsigt i indledningen og progression mekanismerne i menneskelige sygdomme som kræft. Transgene og betinget knockout mus har været hyppigt anvendt til gen overekspression eller ablation i specifikke væv eller celler typer in vivo. Imidlertid kan generere kønscelleoverførsel musemodeller være tidskrævende og dyrt. De seneste fremskridt i gen redigering teknologier og muligheden for at levere DNA plasmider ved virusinfektion har aktiveret hurtige generation af ikke-kønscelleoverførsel autokton musemodeller kræft til flere organer. Blæren er et organ, der har været svært for virale vektorer adgang til, på grund af tilstedeværelsen af en glykosaminoglykan lag, der dækker urothelium. Her, vi beskriver en ny metode udviklet i laboratoriet for effektiv levering af DNA plasmider i mus blære urothelium in vivo. Gennem intravesikal instillation af pCAG-NGL DNA plasmid og elektroporation af kirurgisk udsatte blære viser vi, at DNA plasmid kan leveres specielt i blæren urothelial celler for forbigående udtryk. Vores metode giver en hurtig og bekvem måde for overekspression og knockdown af gener i mus blæren, og kan anvendes til at opbygge GEMMs af blærekræft og andre urologiske sygdomme.

Til at påvise succes af genet levering i blære urothelium, brugte vi pCAG-NGL15 plasmid for elektroporation. 20 µL plasmid og Trypan blå løsning var injiceres gennem urinrøret og 5 elektriske impulser blev administreret. Efter 48 h, vi dissekeret mus blæren og observeret pletter af normal god landbrugspraksis fluorescens under en dissektion fluorescens mikroskop, der henviser til, at en negativ styre blæren, der ikke undergår elektroporation viste ingen no...
