The transformational impact of site-specific DNA modifiers on biomedicine and agriculture

Polkoff, KathrynPiedrahita, Jorge A

The development of genetically modified livestock has been dependent on incremental technological advances such as embryo transfer, homologous recombination, and somatic cell nuclear transfer (SCNT). This development rate has increased exponentially with the advent of targeted gene modifiers such as zinc finger nucleases, TAL-effector nucleases (TALENs) and clustered regularly interspaced short palindromic repeats (CRISPR-Cas). CRISPR-Cas based systems in particular have broad applicability, and have low technical and economic barriers for their implementation. As a result, they are having, and will continue to have, a transformational impact in the field of gene editing in domestic animals. With these advances also comes the responsibility to properly apply this technology so it has a beneficial effect throughout all levels of society.(AU)
