Wnt-7b CRISPR Activation Plasmid (h): sc-401626-ACT
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Wnt-7b CRISPR Activation Plasmid (h) is a synergistic activation mediator (SAM) transcription activation system designed to specifically upregulate gene expression
- Wnt-7b CRISPR Activation Plasmid (h) consists of three plasmids at a 1:1:1 mass ratio: a plasmid encoding the deactivated Cas9 (dCas9) nuclease (D10A and N863A) fused to the transactivation domain VP64, and a blasticidin resistance gene; a plasmid encoding the MS2-p65-HSF1 fusion protein, and a hygromycin resistance gene; a plasmid encoding a target-specific 20 nt guide RNA fused to two MS2 RNA aptamers, and a puromycin resistance gene
- The resulting SAM complex binds to a site-specific region approximately 200-250 nt upstream of the transcriptional start site and provides robust recruitment of transcription factors for highly efficient gene activation
- gRNAs encoded by Wnt-7b CRISPR Activation Plasmid (h) and Wnt-7b CRISPR Activation Plasmid (h2) target distinct regulatory regions upstream of the WNT7B transcriptional start site. One or both designs may be available

WNT7B encodes the secreted glycoprotein Wnt-7b, a ligand that activates Frizzled/LRP receptor complexes to regulate canonical β-catenin signaling as well as non-canonical Wnt pathways depending on cellular context. Wnt-7b contributes to cell fate specification, tissue patterning, epithelial–mesenchymal interactions, and control of proliferation and differentiation programs through transcriptional regulation of Wnt target genes. Dysregulated WNT7B expression or pathway activity has been linked to developmental abnormalities and to aberrant signaling states observed across multiple disease-relevant settings, including cancer-related processes such as altered growth, invasion, and tumor microenvironment crosstalk. Modulating WNT7B provides a tractable route to interrogate Wnt-dependent transcriptional networks and pathway crosstalk with MAPK, PI3K/AKT, and TGF-β signaling.
Wnt-7b CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous WNT7B expression without altering the underlying DNA sequence.
Wnt-7b CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the WNT7B 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 WNT7B transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Wnt-7b expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native WNT7B locus and enabling the study of Wnt-7b-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Wnt-7b pathway restoration in tumor cells with silenced or reduced WNT7B expression.
