ChM-1 CRISPR Activation Plasmid (h) | sc-403523-ACT | 20 µg | $397.00 |
CNMD encodes chondromodulin-1 (ChM-1), a secreted extracellular matrix-associated protein enriched in avascular cartilage and implicated in maintaining the anti-angiogenic microenvironment of developing and mature connective tissues. ChM-1 participates in regulation of endothelial cell behavior, cartilage homeostasis, and extracellular matrix remodeling, linking it to pathways that coordinate tissue vascularization and chondrogenic differentiation. Altered CNMD expression has been investigated in contexts of cartilage degeneration and aberrant neovascularization, where shifts in matrix signaling can influence inflammatory and hypoxic responses. As a result, CNMD is widely studied in musculoskeletal biology, vascular biology, and tumor microenvironment research as a modulator of stromal-vascular crosstalk.
ChM-1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous CNMD expression without altering the underlying DNA sequence.
ChM-1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the CNMD 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 CNMD transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous ChM-1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native CNMD locus and enabling the study of ChM-1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of ChM-1 pathway restoration in tumor cells with silenced or reduced CNMD expression.
