DUOX1 (dual oxidase 1) encodes a membrane-associated NADPH oxidase that generates hydrogen peroxide at epithelial surfaces, supporting host defense and redox-dependent signaling. Through regulated reactive oxygen species production, DUOX1 influences innate immune responses, mucosal barrier biology, and redox control of pathways such as MAPK and NF-κB that shape inflammatory gene expression and wound repair. Altered DUOX1 expression or activity has been linked to dysregulated oxidative stress and epithelial remodeling in airway and gastrointestinal disease contexts. In human cell models, DUOX1 serves as a tractable node for dissecting how localized H₂O₂ modulates signaling networks, cytokine programs, and oxidative damage responses.
DUOX1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous DUOX1 expression without altering the underlying DNA sequence.
DUOX1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the DUOX1 locus in human cell lines. The system is built around a catalytically inactive Cas9 (dCas9) carrying two inactivating mutations (D10A and N863A) that eliminate nuclease activity while preserving DNA binding. This dCas9 is fused to VP64, a potent transcriptional activator, and is co-expressed with a blasticidin resistance gene for selection. The second plasmid encodes the MS2-p65-HSF1 fusion protein, a secondary activator complex that works in concert with dCas9-VP64, alongside a hygromycin resistance gene. The third plasmid encodes a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers that recruit the MS2-p65-HSF1 complex to the activation site, accompanied by a puromycin resistance gene. The three plasmids are delivered at a 1:1:1 mass ratio for balanced expression of all system components.
Once assembled at the target locus, the SAM complex binds within approximately 200 bp upstream of the DUOX1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous DUOX1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native DUOX1 locus and enabling the study of DUOX1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of DUOX1 pathway restoration in tumor cells with silenced or reduced DUOX1 expression.
