GPC3 encodes glypican-3, a glycosylphosphatidylinositol (GPI)-anchored heparan sulfate proteoglycan localized to the cell surface and extracellular matrix interface. Glypican-3 modulates the availability and signaling range of morphogens and growth factors, influencing pathways including Wnt/β-catenin, Hedgehog, FGF, and BMP to regulate cell proliferation, adhesion, and developmental patterning. Altered GPC3 expression is linked to dysregulated tissue growth and oncogenic signaling programs, and is widely studied as a context-dependent regulator in liver biology and tumor-associated cell states. These properties make GPC3 a useful entry point for dissecting heparan sulfate–dependent signaling, receptor–ligand interactions, and microenvironmental regulation of growth factor gradients.
glypican-3 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous GPC3 expression without altering the underlying DNA sequence.
glypican-3 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the GPC3 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 GPC3 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous glypican-3 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native GPC3 locus and enabling the study of glypican-3-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of glypican-3 pathway restoration in tumor cells with silenced or reduced GPC3 expression.
