De eerste publicatie met green fluorescent protein (GFP) als reporter substraat voor ubiquitine-proteasoom-activiteit werd gepubliceerd in 2000 12. Sindsdien is GFP uitgegroeid tot een gemeenschappelijk instrument om cellulaire activiteiten, in het bijzonder het ubiquitine-proteasoom-proces te visualiseren. Om ubiquitine-proteasoom activiteit in vivo volgen van een transgeen muismodel met een GFP-reporter gebaseerde geïntroduceerd 13. Extra in vivo onderzoek bleek een transgeen m...

monitoring of ubiquitin-proteasome activity in living cells using a degron (dgn)-destabilized green fluorescent protein (gfp)-based reporter protein

Proteasoom is de belangrijkste intracellulaire organellen betrokken bij de proteolytische afbraak van abnormale, verkeerd gevouwen, beschadigd of geoxideerde eiwitten 1, 2. Onderhoud van proteasoom activiteit werd betrokken bij veel belangrijke cellulaire processen, zoals stress cel respons 3, celcyclus regulatie en cellulaire differentiatie 4 of in het immuunsysteem reactie 5. Het disfunctioneren van de ubiquitine-proteasoom-systeem is gerelateerd aan de ontwikkeling van tumoren en neurodegeneratieve ziekten 4, 6. Daarnaast werd een afname in activiteit gevonden proteasoom als functie van cellulaire ouderdom en veroudering organismale 7, 8, 9, 10. Hier geven we een methode om ubiquitine-proteasoom te meten in levende cellen met een GFP-fusie-eiwit dgn. Om ubiquitine-proteasoom activiteit volgen in levende elementen, complementaire DNA constructen die coderen voor een groen fluorescerend eiwit (GFP)-dgn fusie-eiwit (GFP-dgn, unstable) en een variant die een frameshift mutatie (GFP-dgnFS, stabiele 11) ingevoegd in lentivirale expressievectoren. We verkiezen deze techniek meer traditionele transfectietechnieken omdat het garandeert een zeer hoge transfectie-efficiëntie onafhankelijk van het celtype of de leeftijd van de donor. Het verschil tussen fluorescentie weergegeven door de GFP-dgnFS (stable) eiwit en de gedestabiliseerd eiwit (GFP-dgn) in de afwezigheid of aanwezigheid van proteasoom inhibitor kan worden gebruikt om ubiquitine-proteasoom activiteit schatten in elk afzonderlijk cellijn. Deze verschillen kunnen worden gecontroleerd door epifluorescentiemicroscopie of kan worden gemeten door middel van flowcytometrie.
