Macrophage migration inhibitory factor (MIF) is a pleiotropic cytokine and enzymatic protein that regulates innate and adaptive immune responses by modulating macrophage activation, leukocyte trafficking, and inflammatory mediator production. It interfaces with receptor-driven signaling via CD74 and chemokine receptors such as CXCR2/CXCR4/CXCR7, engaging downstream MAPK and NF-κB pathways that shape cytokine release, cell survival, and stress responses. MIF also contributes to redox homeostasis and can influence cell-cycle control and apoptosis, linking inflammatory cues to broader cellular programs. Dysregulated MIF signaling has been associated with chronic inflammatory diseases, autoimmune phenotypes, and tumor-associated inflammation, making it a frequent target for mechanistic studies in immunology and cancer biology.
MIF Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the MIF locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within MIF. 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 MIF 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 MIF-disrupted clones.
