New CRISPR editing technique removes methylation marks to reactivate silenced genes
Researchers have developed a third-generation CRISPR technique that modifies gene expression by removing methylation marks rather than cutting DNA sequences. The approach uses catalytically dead Cas9 proteins fused to demethylating enzymes, offering a potentially safer alternative to conventional gene editing for treating inherited blood disorders including sickle cell disease and β-thalassemia.
