Near-infrared light activatable chemically induced CRISPR system.

ABSTRACT: The biggest challenge in using CRISPR technologies, which limits their widespread application in medicine, is off-target effects. These effects could, in principle, be minimized by ensuring that CRISPR is activated primarily in the targeted cells, thereby reducing the likelihood of unintended genetic modifications in non-target tissues. Therefore, the development of a light activatable CRISPR approach to dynamically control gene activation in both space and time would be highly beneficial. A drawback is that the overwhelming majority of recently introduced light activatable CRISPR systems require UV or blue light exposure, severely limiting the penetration depth of light in tissue at which CRISPR can be activated, and, in the case of UV light, raising safety concerns. A small number of sys
