- Embedded CRISPR interference (emCRISPRi) enhances gene-silencing efficiency in Drosophila.
- emCRISPRi integrates transcriptional repression domains (Mxi and TRD) into dCas9, improving silencing efficiency.
- The platform enables robust repression of coding genes and cis-regulatory elements, especially near transcription start sites (TSS).
- emCRISPRi outperforms RNA interference (RNAi) in gene-silencing activity at several loci.
- It facilitates strong phenotypic rescue using unmodified cDNA.
- Demonstrated applications include dissecting Hippo pathway interactions and mitigating TDP-43-induced neurotoxicity in an ALS model.
- emCRISPRi is a promising tool for functional genomics, enhancer studies, and disease modeling in Drosophila.
- Potential for cross-species adaptation and therapeutic innovation.
