Abstract
Genetically modified pigs are becoming an invaluable animal model for agricultural, pharmaceutical, and biomedical applications. Unlike traditional transgenesis, which is accomplished by randomly inserting an exogenous transgene cassette into the natural chromosomal context, targeted genome editing confers precisely editing (e.g., mutations or indels) or insertion of a functional transgenic cassette to user-designed loci. Techniques for targeted genome engineering are growing dramatically and include, e.g., zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) systems. These systems provide enormous potential applications. In this chapter, we review the use of TALENs for targeted genome editing with focus on their application in pigs. In addition, a brief protocol, including construction of sequence-specific TALENs, delivery of TALENs into primary porcine fibroblasts, and detection of TALEN-mediated cleavage, is described. This chapter is useful for scientists who are inexperienced with TALEN engineering of porcine cells as well as of other large animals.
