Characterization of SHARPIN knockout Syrian hamsters developed using CRISPR/Cas9 system

Background : SHARPIN (SHANK- associated RH domain interactor) is a component ofthe linear ubiquitination complex that regulates the NF- κB signaling pathway. To betterunderstand the function of SHARPIN, we sought to establish a novel geneticallyengineered Syrian hamster with SHARPIN disruption using the CRISPR/Cas9 system.Methods : A single- guide ribonucleic acid targeting exon 1 of SHARPIN gene was designedand constructed. The zygotes generated by cytoplasmic injection of the Cas9/gRNA ribonucleoprotein were transferred into pseudopregnant hamsters. Neonatalmutants were identified by genotyping. SHARPIN protein expression was detectedusing Western blotting assay. Splenic, mesenteric lymph nodes (MLNs), and thymicweights were measured, and organ coefficients were calculated. Histopathologicalexamination of the spleen, liver, lung, small intestine, and esophagus was performedindependently by a pathologist. The expression of lymphocytic markers and cytokineswas evaluated using reverse transcriptase- quantitative polymerase chain reaction.Results : All the offspring harbored germline- transmitted SHARPIN mutations.Compared with wild- type hamsters, SHARPIN protein was undetectable in SHARPIN −/−hamsters. Spleen enlargement and splenic coefficient elevation were spotted inSHARPIN −/− hamsters, with the descent of MLNs and thymuses. Further, eosinophilinfiltration and structural alteration in spleens, livers, lungs, small intestines, and esophagiwere obvious after the deletion of SHARPIN. Notably, the expression of CD94 and CD22 was downregulated in the spleens of knockout (KO) animals. Nonetheless,the expression of CCR3, CCL11, Il4 , and Il13 was upregulated in the esophagi. Theexpression of NF- κB and phosphorylation of NF- κB and IκB protein significantly diminishedin SHARPIN −/− animals.Conclusions : A novel SHARPIN KO hamster was successfully established using theCRISPR/Cas9 system. Abnormal development of secondary lymphoid organs andeosinophil infiltration in multiple organs reveal its potential in delineating SHARPINfunction and chronic inflammation.
