VEGF-D CRISPR Activation Plasmid (h) | sc-401669-ACT | 20 µg | $397.00 |
Human VEGFD encodes VEGF-D, a secreted growth factor that signals primarily through VEGFR-3 and, following proteolytic processing, can also engage VEGFR-2 to promote lymphatic and vascular endothelial cell proliferation, migration, and survival. VEGF-D contributes to lymphangiogenesis, vascular remodeling, and extracellular matrix–linked signaling crosstalk with PI3K–AKT, MAPK/ERK, and SRC-family pathways. Its expression is regulated by developmental and inflammatory cues and is often studied in the context of endothelial differentiation, tissue fluid homeostasis, and immune cell trafficking. Dysregulated VEGF-D activity has been associated with pathological lymphatic remodeling and tumor-associated vascular/lymphatic changes, supporting its relevance in mechanistic models of cancer biology and inflammatory disease.
VEGF-D CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous VEGFD expression without altering the underlying DNA sequence.
VEGF-D CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the VEGFD 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 VEGFD transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous VEGF-D expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native VEGFD locus and enabling the study of VEGF-D-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of VEGF-D pathway restoration in tumor cells with silenced or reduced VEGFD expression.
