Human MDK encodes midkine (MK), a secreted heparin-binding growth factor that modulates cell proliferation, survival, migration, and neurite outgrowth. MK signals through multiple cell-surface partners, including receptor protein tyrosine phosphatase β/ζ and members of the LDL receptor-related protein family, influencing downstream pathways such as MAPK/ERK, PI3K/AKT, and inflammatory signaling programs. Expression of MDK is tightly regulated during development and is frequently elevated in contexts of oncogenic signaling, tissue stress, and remodeling. Dysregulated MK activity has been associated with tumor progression, angiogenesis, immune cell recruitment, and fibrotic or neuroinflammatory processes, making MDK a useful target for mechanistic studies of microenvironmental signaling.
MK Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the MDK locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within MDK. 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 MDK 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 MDK-disrupted clones.
