From: Targeting miRNA by CRISPR/Cas in cancer: advantages and challenges
An illustration shows applying Ca12a instead of Cas9 protein, which has the ability to recognize PAM sequences in miRNA editing. By altering the miR-21 coding sequences in glioma cells, CRISPR/Cas12a decreases miR-21 expression through microenvironment cells, which controls both in vitro and in vivo cell proliferation.
