ASCL1 (achaete-scute family bHLH transcription factor 1) is a proneural regulator that drives neuronal lineage commitment and differentiation by binding E-box motifs and coordinating transcriptional programs controlling cell cycle exit, neurite outgrowth, and neurogenic fate decisions. In development and cellular reprogramming contexts, ASCL1 interfaces with Notch signaling and chromatin remodeling to balance progenitor maintenance versus differentiation, and it is commonly used as a marker and effector of neuroendocrine-like transcriptional states. Dysregulated ASCL1 expression has been linked to aberrant lineage plasticity and altered neuroendocrine differentiation programs, making it relevant for studying transcriptional circuitry in neural development and tumor biology. These properties support investigations into cell fate specification, transcription factor networks, and epigenetic control of neuronal gene expression.
ASCL1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ASCL1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ASCL1. 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 ASCL1 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 ASCL1-disrupted clones.
