Developmental & Comparative Immunology, Journal Year: 2017, Volume and Issue: 75, P. 86 - 98

Published: March 1, 2017

The interplay between nutrition and immune system is well recognised, however the true integration of research nutrition, animal energy status function still far from clear. In fish especially for species maintained in aquaculture, formulated feeds are significantly different natural diet with recent changes nutrient sources, protein oil sources now being predominated by terrestrial derived ingredients. Additionally, many incorporated to health management termed functional feeds, which believed improve health, reduce disease outbreaks and/or post-infection recovery. Using new omics technologies, including transcriptomics (microarray RNA-seq) proteomics, impacts on becoming clearer. By using molecular pathway enrichment analysis, modules genes can indicate how both local (intestinal) systemic altered. Although great progress has been made define host function, understanding intestinal microbiome only just beginning emerge.

Generation of Myostatin Gene-Edited Channel Catfish (Ictalurus punctatus) via Zygote Injection of CRISPR/Cas9 System

Scientific Reports, Journal Year: 2017, Volume and Issue: 7(1)

Published: July 31, 2017

Abstract The myostatin (MSTN) gene is important because of its role in regulation skeletal muscle growth all vertebrates. In this study, CRISPR/Cas9 was utilized to successfully target the channel catfish, Ictalurus punctatus , suppressor MSTN. induced high rates (88–100%) mutagenesis protein-encoding sites MSTN-edited fry had more cells ( p < 0.001) than controls, and mean body weight gene-edited increased by 29.7%. nucleic acid alignment mutated sequences against wild-type sequence revealed multiple insertions deletions. These results demonstrate that a highly efficient tool for editing catfish genome, opens ways facilitating genetic enhancement functional genomics. This approach may produce growth-enhanced increase productivity.
