CRISPR/Cpf1-mediated editing of DNM1L in induced pluripotent stem cells.

The dynamin-1-like protein (DNM1L), also termed DRP1, is essential for mitochondrial fission. Mutations in DNM1L are associated with neurological disorders and cardiac dysfunction. To decipher the role of DNM1L in human induced pluripotent stem cells (hiPSCs) and in their differentiated counterparts, we used CRISPR/Cpf1 and generated a human iPSC line with a mutation by targeting exon 18 of the DNM1L gene. The generated compound heterozygous (biallelic) DNM1L mutant cell line showed normal cell morphology, genomic stability, and expression of classical stem cell markers. Furthermore, the cells can be differentiated efficiently into the three germ layers meso-, endo-, and ectoderm.

CRISPR/Cas9-mediated editing of ERCC6 in iPSCs: A disease model for Cockayne Syndrome type B.

Cockayne Syndrome type B (CSB) is caused by mutations in the ERCC6 gene, which encodes a key protein involved in transcription-coupled nucleotide excision repair (TC-NER) and chromatin remodeling. Deficiency in CSB leads to defective transcriptional recovery after DNA damage, oxidative stress accumulation, and progressive neurodegeneration. In this work, we generated a CRISPR/Cas9-engineered human induced pluripotent stem cell (iPSC) line, IUFi004-A-12, carrying a homozygous mutation in ERCC6 causing a premature stop codon in its 10th exon. The modified iPSCs displayed normal morphology, expressed pluripotency markers, and differentiated into all three germ layers. This model enables mechanistic studies of CSB dysfunction and facilitates therapeutic development for Cockayne Syndrome.
