Abstract

Creating mouse models of human genetic disease (Gurumurthy and Lloyd, Dis Models Mech 12(1):dmm029462, 2019) and livestock trait (Schering et al. Arch Physiol Biochem 121(5):194-205, 2015; Habiela et al. J Gen Virol 95 (Pt 11):2329-2345, 2014) have been proven to be a useful tool for understanding the mechanism behind the phenotypes and fundamental and applied research in livestock. A single base pair deletion of prolactin receptor (PRLR) has an impact on hair morphology phenotypes beyond its classical roles in lactation in cattle, the so-called slick cattle (Littlejohn et al. Nat Commun 5:5861, 2014). Here, we generate a knock-in mouse model by targeting the specific locus of PRLR gene using Cas9-mediated genome editing via homology-directed repair (HDR) in mouse zygotes. The mouse model carrying the identical PRLR mutation in slick cattle may provide a useful animal model to study the pathway of thermoregulation and the mechanism of heat-tolerance in the livestock.

Keywords: CRISPR; Genome editing; Heat-tolerance; Homology-directed repair; Prolactin receptor; Thermoregulation; Zygote microinjection.
