Genome editing in cultured fishes

چکیده
Abstract With external fertilization, high fecundity, and established methods for propagation larval rearing cultured species, fish provide systems well suited to genome-editing procedures. While early experiments utilized zinc-finger nucleases transcription activator-like effector (TALENs), most recent ones have used the CRISPR/Cas9 editor, achieved rates of targeted genomic insertion above those classical transgenic methods, with lower frequencies off-site integration. Genome-editing fishes focused on improving growth rate disease resistance, achievement reproductive confinement, other valued traits. As reviewed here, advances in knowledge key molecular pathways and, some cases, favorable alterations phenotype been achieved. For example, loss-of-function myostatin, a negative regulator muscle growth, led increased mass, greater weight, fillet yield genome-edited lines red sea bream, tiger puffer, Nile tilapia than their unedited counterparts. The bream line become first animal reach commercial production. all animals, wide adoption will depend upon addressing issues regulation, consumer acceptance, breeding infrastructure.

CRISPR/Cas9-Directed Genome Editing of Cultured Cells.
Human genome engineering has been transformed by the introduction of the CRISPR (clustered regularly interspaced short palindromic repeats)/Cas (CRISPR-associated) system found in most bacteria and archaea. Type II CRISPR/Cas systems have been engineered to induce RNA-guided genome editing in human cells, where small RNAs function together with Cas9 nucleases for sequence-specific cleavage of t...
متن کاملGenome-size evolution in fishes
Fishes possess both the largest and smallest vertebrate genomes, but the evolutionary significance of this variation is unresolved. The present study provides new genome-size estimates for more than 500 species, with a focus on the cartilaginous and ray-finned fishes. These results confirm that genomes are smaller in ray-finned than in cartilaginous fishes, with the exception of polyploids, whi...

Custom genome editing has become an essential element of molecular biology. In particular, the generation of fusion constructs with epitope tags or fluorescent proteins at the genomic locus facilitates the analysis of protein expression, localization, and interaction partners at physiologic levels. Following up on our initial publication, we now describe a considerably simplified, more efficien...
