BACKGROUND Egg laying in Magang geese is characterized by extended interruption between clutches and lowing laying rate. Both the ovarian follicular development and ovulation characteristics, and the associated endocrine and molecular regulatory mechanisms involved are poorly understood, but could be important for guiding development of molecule aided(More)
OBJECTIVE To investigate the effect of immunization with prokaryotically expressed recombinant fusion protein of extracellular near-transmembrane domain of Tibet minipig leptin receptor (OBR) on fat deposition in SD rats. METHODS A pair of specific primers containing BamHI and HindIII restriction enzyme sites was designed to amplify the extracellular(More)
Myostatin (Mstn) is a conserved negative regulator of skeletal muscle mass in mammals. However, whether precise disruption of Mstn in livestock can be achieved and safely used to improve meat productivity has not been proven. We applied CRISPR/Cas9 system to generate Mstn knock-out (KO) rabbits and goats and then analyzed the changes in their phenotypes to(More)
Goat's milk, considered a substitute for cow's milk, has a high nutritional value. However, goat's milk contains various allergens, predominantly β-lactoglobulin (BLG). In this study, we employed the CRISPR/Cas9 system to target the BLG locus in goat fibroblasts for sgRNA optimization and generate BLG knock-out goats through co-injection of Cas9 mRNA and(More)
This study aims to knock out the goat β-lactoglobulin (BLG) gene using CRISPR-Cas9 system and knock in human lactoferrin (hLF) at the BLG locus, and further study the effect of RAD51 stimulatory compound (RS-1) on homologous recombination efficiency. First, we designed an sgRNA targeting the first exon of goat BLG gene and constructed a co-expression vector(More)
