DDIT4 encodes REDD-1 (regulated in development and DNA damage response 1), a stress-inducible inhibitor of mTORC1 signaling that links hypoxia, nutrient deprivation, oxidative stress, and DNA damage to metabolic adaptation. REDD-1 promotes TSC1/2-dependent restraint of mTORC1, influencing protein synthesis, autophagy, mitochondrial function, and cell survival programs. Transcriptional control of DDIT4 is commonly mediated by stress-responsive factors such as HIF-1 and p53, positioning REDD-1 as a rapid modulator of growth versus conservation states. Dysregulated DDIT4/REDD-1 expression has been associated with altered stress tolerance and metabolic remodeling observed across cancer biology, neurobiology, and cardiometabolic research contexts.
REDD-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the DDIT4 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within DDIT4. 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 DDIT4 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 DDIT4-disrupted clones.
