Abstract: Disclosed herein include methods and compositions for incorporating an effector gene into the genome of a cell. The method can comprise introducing into a cell a donor nucleic acid comprising a recognition site, a splice acceptor site, a self-cleaving peptide sequence, an effector gene, and an optional transcript stabilization element. The donor nucleic acid can be incorporated into the intron of a target gene differentially expressed in a unique cell type and/or in a cell during a unique cell state via non-homologous end joining (NHEJ)-dependent DNA repair. There are also provided, in some embodiments, methods and compositions for treating a disease or disorder in a subject.
