WebDec 17, 2024 · The team tested twin PE plus Bxb1 recombinase by inserting large DNA into a variety of target sites in the human genome, including at “safe harbor loci” thought to be ideal for gene therapy because inserting genes there has been found to not induce cancer or other apparent toxicities. WebTargeted insertion of large pieces of DNA is an important goal of genetic engineering. However, this goal has been elusive since classical methods for homology-directed repair are inefficient and often not feasible in many systems.
