RNA-Triggered Cell Killing with CRISPR–Cas12a2

RNA-triggered cell killing with CRISPR–Cas12a2

Selectively eradicating target cells on the basis of their genetic or transcriptional identity remains important in basic research, medicine, biotechnology and agriculture1–3. For applications involving bacteria, CRISPR nucleases offer promising options due to their ability to enact RNA-guided counterselection4–7; however, using these same nucleases for counterselection in eukaryotes has proven much more restrictive8–14. Here we show that Cas12a…

Scientists Demonstrate CRISPR's Precision in Targeting and Eliminating

In a groundbreaking advancement in molecular biology and genetic medicine, researchers at Utah State University, led by Associate Professor Ryan Jackson and doctoral candidate Kadin Crosby, have unveiled compelling new insights into the CRISPR-Cas12a2 system that promise to revolutionize targeted disease treatment. Published on May 6, 2026, in the prestigious journal Nature, this study elucidates the unique and highly specific RNA-targeted cell-…

Next Generation CRISPR Gene Editing Could Help Target Cancer Cells

A CRISPR gene editing protein called Cas12a2 can be turned into a kind of programmable self‑destruct switch for cells, which researchers think could be a new way to treat conditions like cancer if the technique is validated. Cas12a2 eliminates eukaryotic cells based purely on which RNA transcripts they express, and the investigators showed this can be used to selectively destroy virus‑infected cells, unedited cells, and cancer cells bearing a si…
