FGF5 encodes fibroblast growth factor 5 (FGF-5), a secreted mitogenic ligand that signals through FGFR tyrosine kinase receptors to regulate cell proliferation, differentiation, and tissue remodeling. FGF-5 activity engages canonical growth factor cascades including MAPK/ERK and PI3K/AKT, influencing epithelial–mesenchymal interactions and developmental programs. In human biology, altered FGF5 expression has been linked to dysregulated growth signaling and is frequently studied in contexts such as skin and hair follicle cycling, wound-associated remodeling, and oncogenic pathway activation. These features make FGF5 a useful node for dissecting FGFR-driven signaling dynamics and transcriptional control of growth factor networks.
FGF-5 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous FGF5 expression without altering the underlying DNA sequence.
FGF-5 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the FGF5 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 FGF5 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous FGF-5 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native FGF5 locus and enabling the study of FGF-5-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of FGF-5 pathway restoration in tumor cells with silenced or reduced FGF5 expression.
