Combing hiPSCs with CRISPR/Cas9
Mutations in the genes PARK2 (parkin) cause autosomal recessive familial Parkinson's disease. In this study, human iPSCs with PARK2 knockout introduced by genome editing have enabled investigations of parkin dysfunction in human dopaminergic neurons in vitro. This research identified and quantified more than half of all reported mitochondrial proteins and determined large numbers of dysregulated proteins in PARK2 KO neurons compared to healthy isogenic controls. Structural and functional analyses revealed an increase in mitochondrial area and the presence of elongated mitochondria as well as impaired glycolysis and lactate-supported respiration, leading to impaired cell survival in PARK2 KO neurons. This adds valuable insight into the effect of parkin dysfunction in human neurons and provides knowledge of disease-related pathways that can potentially be targeted for therapeutic intervention.
Develop a genome modified iPSC with Ubigene today! Ubigene developed CRISPR-UTM (based on CRISPR/Cas9 technology) which is more efficient than general CRISPR/Cas9 in double-strand breaking, and CRISPR-UTM can greatly improve the efficiency of homologous recombination.
