Mouse Zhx2 encodes the zinc fingers and homeoboxes 2 (ZHX2) transcription factor, a predominantly nuclear regulator that modulates gene expression programs controlling cellular differentiation, proliferation, and metabolic homeostasis. ZHX2 functions within transcriptional repression/activation networks through DNA-binding zinc finger and homeobox domains, shaping tissue-specific transcriptional states. In murine systems, altered Zhx2 activity has been linked to dysregulated hepatic gene expression, developmental phenotypes, and context-dependent effects on oncogenic signaling and tumor suppressive programs. These properties make ZHX2 a useful node for dissecting transcriptional control of lineage identity and disease-associated gene regulatory circuits.
ZHX2 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Zhx2 expression without altering the underlying DNA sequence.
ZHX2 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Zhx2 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 Zhx2 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous ZHX2 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Zhx2 locus and enabling the study of ZHX2-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of ZHX2 pathway restoration in tumor cells with silenced or reduced Zhx2 expression.
