Cas9 is a groundbreaking molecular tool in the field of genetic engineering, discovered in 2012 by Jennifer Doudna and Emmanuelle Charpentier. It is an RNA-guided DNA endonuclease derived from the bacterial CRISPR-Cas immune system. Cas9 enables precise genome editing by inducing double-strand breaks at specific target sites within the DNA sequence. This technology revolutionized gene editing due to its simplicity, efficiency, and versatility.
SY5Y, a human neuroblastoma cell line, has been extensively employed in neuroscience research. Originally established in 1970, SY5Y cells exhibit characteristics reminiscent of immature sympathetic neurons, making them a valuable model for studying neuronal development, differentiation, and neurodegenerative diseases.
The development of Cas9 Stable Cell Line-SH-SY5Y integrates the power of Cas9 technology with the utility of the SY5Y cell line. This engineered cell line, established in recent years, facilitates efficient and precise genome editing within the SY5Y cellular context. It serves as a potent tool for elucidating the molecular mechanisms underlying neurodevelopmental processes and neurological disorders, offering unprecedented opportunities for advancing our understanding of neuronal biology.
Researchers employed CRISPR‐Cas9 technology to investigate the impact of a rare mutation (rs144662445) in the AKAP9 gene, linked to Alzheimer's disease (AD) in African Americans (AA), on tau pathology and the tau interactome in SH‐SY5Y P301L neuron‐like cells. The mutation notably elevated phosphorylated tau levels, particularly at Ser396/Ser404. Additionally, analysis of the tau interactome revealed dysregulation of RNA translation, localization, and oxidative activity, resembling findings from human AD brain samples. Functional assays confirmed reduced protein synthesis and increased oxidative stress, mimicking AD pathology. These findings highlight the role of AKAP9 in AD pathogenesis.
