Abstract
Nonrodent animal models have recently become more valuable in preclinical studies. The limitation of nonrodent animal models is that they must demonstrate relatively reliable and predictable responses in addition to representing complex etiologies of a genetically diverse patient population. In our study, we applied CRISPR/Cas9 technology to produce transgenic rabbits. This approach can be useful for creating genetically divergent and homogeneous populations for studies in translational medicine. NADPH oxidase 4 (NOX4) is a promising therapeutic target, as it is linked to several pathologies including stroke, atherosclerosis, and lung and kidney fibrosis. NOX4 knockout (KO) rabbit lines were created in order to study the in vivo effects resulting from a lack of NOX4 protein and loss of gene function. One of the knockout founders was a germline multiallelic knockout male. Its offspring segregated into three distinct NOX4 knockout and a wild-type lines. Mosaicism is a relatively frequent phenomenon in rabbit transgenesis. Our results point to the possible application of mosaicism in preclinical studies. However, careful planning and evaluation of results are necessary. The predicted off-target sites were studied as well, and no signs of off-target events were detected.
