Abstract

Short guide RNAs (gRNAs) can direct catalytically inactive CRISPR-associated 9 nuclease (dCas9) to repress endogenous genes in bacteria and human cells. Here we show that single or multiple gRNAs can direct dCas9 fused to a VP64 transcriptional activation domain to increase expression of endogenous human genes. This proof-of-principle work shows that clustered regularly interspaced short palindromic repeat (CRISPR)-Cas systems can target heterologous effector domains to endogenous sites in human cells.
