Human ANG encodes angiogenin (ANG I), a secreted RNase A superfamily protein that regulates endothelial cell migration, proliferation, and neovascular responses. Beyond its extracellular signaling roles, angiogenin can be internalized and influence rRNA transcription and stress-adaptive programs through tRNA cleavage and generation of tiRNAs, linking it to translational control. ANG-dependent pathways intersect with hypoxia responses, extracellular matrix remodeling, and inflammatory signaling that shape tissue vascularization. Dysregulated ANG expression or activity has been associated with altered angiogenic balance in cancer biology and neurodegeneration research contexts, including studies of motor neuron vulnerability.
ANG I Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ANG locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ANG. 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 ANG 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 ANG-disrupted clones.
