TNC encodes tenascin-C, a large extracellular matrix glycoprotein that is strongly induced during development, tissue remodeling, and inflammation. Tenascin-C modulates cell–matrix adhesion, migration, and mechanotransduction by interacting with integrins and other matrix components, shaping focal adhesion and cytoskeletal signaling. Through effects on pathways such as FAK/Src, MAPK/ERK, and TGF-β-associated remodeling programs, it contributes to regulation of stromal organization and immune cell trafficking in dynamic microenvironments. Dysregulated TNC expression and deposition are frequently associated with fibrotic remodeling, chronic inflammatory states, and tumor-associated stroma, making it a relevant target for studying extracellular matrix-driven disease mechanisms.
Tenascin-C Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the TNC locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within TNC. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt TNC function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of TNC-disrupted clones.
