Human HLF (hepatic leukemia factor) encodes a PAR bZIP transcription factor that binds specific promoter elements to coordinate circadian-regulated gene expression and tissue-specific transcriptional programs. HLF participates in transcriptional networks controlling differentiation, metabolic homeostasis, and cellular stress responses through regulation of downstream target genes in liver and hematopoietic lineages. Dysregulated HLF activity has been linked to hematologic malignancy biology, including fusion-driven transcriptional reprogramming, and has also been studied in contexts of circadian disruption and altered metabolic phenotypes. As a nuclear DNA-binding protein, HLF is frequently investigated for its role in gene regulatory circuitry and lineage maintenance.
HLF Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the HLF locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within HLF. 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 HLF 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 HLF-disrupted clones.
