Transcriptomic profiling of interferon responses induced by IVT sgRNAs in CRISPRi HEK293T cells
Listed in NCBI GEO
In this study, we investigated the transcriptional responses induced by in vitro–transcribed (IVT) sgRNAs in a CRISPR interference (CRISPRi) system.
Description
A total of 906 sgRNAs were generated using a commercially available IVT workflow and delivered to HEK293T cells stably expressing dCas9-KRAB-MECP2. RNA sequencing was performed to profile genome-wide transcriptional changes following sgRNA transfection.
Compared with mock-transfected controls, sgRNA-transfected cells exhibited a strong and consistent upregulation of interferon-stimulated genes (ISGs), with prominent enrichment of interferon-α response pathways across the majority of sgRNAs. While most sgRNAs induced robust interferon signaling, a small subset showed a more limited transcriptional response. IFIT1 and IFIT2, two canonical markers of interferon activation, were consistently upregulated and were selected as representative genes for downstream validation.
