CTNNB1 encodes human beta-catenin, a multifunctional protein that couples cadherin-based cell–cell adhesion to gene regulation. In the canonical Wnt pathway, stabilized beta-catenin accumulates in the nucleus and partners with TCF/LEF transcription factors to control programs governing proliferation, differentiation, and stem cell maintenance. Its activity is constrained by the APC–AXIN–GSK3β destruction complex, linking beta-catenin levels to phosphorylation-dependent turnover. Dysregulated CTNNB1 signaling and altered junctional dynamics are widely studied in tumor biology, developmental disorders, and fibrosis-related transcriptional remodeling.
beta-catenin Lentiviral Activation Particles (h) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient CTNNB1 upregulation across a broader range of human cell types.
beta-catenin Lentiviral Activation Particles (h) deliver all functional components of the synergistic activation mediator (SAM) system via lentiviral transduction. The system comprises three particle preparations co-transduced into target cells: one encoding catalytically inactive dCas9 (D10A and N863A mutations) fused to the VP64 transactivation domain with a blasticidin resistance gene; one encoding the MS2-p65-HSF1 fusion protein with a hygromycin resistance gene; and one encoding a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers with a puromycin resistance gene. Following lentiviral transduction and genomic integration of the expression cassettes, the SAM components are stably expressed and assemble at the target locus within the proximal promoter region upstream of the CTNNB1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous beta-catenin expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native CTNNB1 genomic locus and regulatory architecture.
The lentiviral format offers several practical advantages: stable genomic integration supports heritable activation across cell divisions; high-titer particle preparations eliminate the need for in-house viral production; and compatibility with primary, non-dividing, and transfection-resistant cell types expands experimental accessibility. Successful transduction can be confirmed and enriched through triple antibiotic selection using puromycin, hygromycin, and blasticidin.
