| abstractText | It is estimated that more than two thousand genes exhibit testis-predominant expression pattern. The functions of hundreds of these genes have been explored during mouse spermatogenesis. However, there are still many genes whose relevance to reproduction in vivo remains unexplored. Our previous studies, as well as the other documented study, have indicated that Spata34, an evolutionarily conserved gene in metazoan species, was exclusively expressed in mouse testes and involved in spermatogenesis by regulating cell cycle progression. The present study aims to determine the effect of Spata34 gene knockout on mouse reproduction in vivo by generating a Spata34 gene knockout model using CRISPR/Cas9-mediated genome editing technology. We found that the Spata34 gene KO mice had normal fertility compared with wild type mice, and no overt detectable difference was found in testis/body weight ratios, testicular histology, sperm counts and spermatozoa motility parameters between WT and Spata34 KO mice. Our report indicated that the testis-specific-expressed gene Spata34 was not required for male mouse fertility, which will help to avoid unnecessary expenditures and effort by other researchers. |
