New Gene-Editing Tool Targets Mutations with Unmatched Precision

A breakthrough tool called Helicase-Assisted Continuous Editing (HACE) allows scientists to create precise genetic mutations in specific genes without affecting the rest of the genome. By combining helicase enzymes with CRISPR technology, HACE introduces mutations into targeted DNA sequences, advancing our ability to study gene functions and disease mechanisms. The tool has already identified drug resistance mutations in cancer-related genes and splicing defects in blood cancers, showcasing its potential for therapeutic discovery.

How Our Brains Turn Into Smarter Disease Fighters

CRISPR gene editing created the G795A amino acid which was introduced to microglia derived from human stem cells. Researchers were able to transplant the donor microglia immune cells into humanized rodent models while administering an FDA-approved cancer drug called pexidartinib. The inclusion of the amino acid cause the donated microglia to thrive and resist the drug, while the host microglia died. The findings open the door for new methods of using microglia to treat a range of neurodegenerative disorders.
