Generation of ints14 Knockout Zebrafish using CRISPR/Cas9 for the Study of Development and Disease Mechanisms.

ABSTRACT: INTS14/VWA9, a component of the integrator complex subunits, plays a pivotal role in regulating the fate of numerous nascent RNAs transcribed by RNA polymerase II, particularly in the biogenesis of small nuclear RNAs and enhancer RNAs. Despite its significance, a comprehensive mutation model for developmental research has been lacking. To address this gap, we aimed to investigate the expression patterns of INTS14 during zebrafish embryonic development. We generated ints14 mutant strains using the CRISPR/Cas9 system. We validated the gRNA activity by co-injecting Cas9 protein and a single guide RNA into fertilized zebrafish eggs, subsequently confirming the presence of a 6- or 9-bp deletion in the ints14 gene. In addition, we examined the two mutant alleles through PCR
