MDH2 encodes mitochondrial malate dehydrogenase, a NAD-dependent enzyme that catalyzes the reversible conversion of malate to oxaloacetate, supporting the tricarboxylic acid (TCA) cycle and mitochondrial redox homeostasis. Through its role in oxidative metabolism, MDH2 contributes to ATP production, NADH/NAD⁺ balance, and anaplerotic flux that links mitochondrial function to broader carbon metabolism. Perturbation of MDH2 activity can alter respiratory capacity and metabolic signaling, processes frequently interrogated in studies of tumor metabolism, mitochondrial disorders, and neurodegeneration. As a core mitochondrial matrix enzyme, MDH2 is also relevant for investigating metabolic adaptation to hypoxia, nutrient stress, and reactive oxygen species dynamics.
MDH2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the MDH2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within MDH2. 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 MDH2 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 MDH2-disrupted clones.
