Experimentele validatie van enhancer-activiteit wordt het beste benaderd door middel van functieverliesanalyse. Hier wordt een efficiënt protocol gepresenteerd dat CRISPR/Cas9-gemedieerde deletie gebruikt om allelspecifieke regulatie van genregulatie in F1 ES-cellen te bestuderen die een hybride genoom bevatten (Mus musculus129 x Mus castaneus).

De noodzakelijke voor het verzamelen van blastocysten procedures, whole-mount immunofluorescentie detectie van eiwitten, beeldvorming van de monsters op een confocale microscoop, en nucleaire segmentatie en beeldanalyse worden beschreven.

Eiwitten vaak meerdere domeinen die verschillende cellulaire functies kunnen uitoefenen. Gene knock-outs (KO) beschouw dit niet als functionele diversiteit. Hier melden wij een recombinatie-gemedieerde cassette uitwisseling (RMCE) gebaseerde structuur-functie benadering KO embryonale stamcellen waarmee de moleculaire dissectie van verschillende functionele domeinen of varianten van een eiwit.

Dit protocol beschrijft de stappen die nodig zijn voor het ontwerpen en uitvoeren multiplexed targeting van versterkers met de deactivering fusieproteïne SID4X-dCas9-KRAB, ook bekend als enhancer interferentie (Enhancer-i). Dit protocol stelt de identificatie van versterkers die regelen van genexpressie en vergemakkelijkt de dissectie van de relaties tussen de versterkers van regulering van een gemeenschappelijk doel-gen.

We rapporteren de toepassing van kwantitatieve chromosoomconformatievangst gevolgd door high-throughput sequencing in embryoïndische lichamen gegenereerd uit embryonale stamcellen. Deze techniek maakt het mogelijk om de contacten tussen putatieve versterkers en promotorgebieden van een bepaald gen te identificeren en te kwantificeren tijdens embryonale stamceldifferentiatie.

Dit protocol biedt een gestroomlijnde computationele pijplijn voor het kwantificeren van ontluikende enhancer-transcripties. Door de toegankelijkheid van chromatine, de chromatinefunctie en transcriptiegegevens te integreren, maakt het nauwkeurige detectie en strengspecifieke analyse van de enhancer-activiteit in complexe intragene regio's mogelijk, terwijl het toegankelijk blijft voor onderzoekers zonder uitgebreide bio-informaticatraining.
