| Research Abstract |
Spermatogenesis is a complex process, and many genes are systematically expressed. We screened 4 genes in maturing rat testis using differential display method. Hrasls5 gene product might function as a tumor suppressor as well as in spermatogenesis, as deduced from its amino acid sequence. RGD1303144 gene was expressed dominantly in spermatocytes. Colon cancer autoantigen gene, Sdccag8, was also localized to the spermatocytes in 7-week-old rat testis, and its protein was detected in the spermatids. Sdccag8 may have a role in the development from spermatocyte to spermatid. In situ hybridization revealed that Ttc29 was expressed primarily in spermatocytes. Ttc29 expression was up-regulated by treatment with FSH. Ttc29 encodes axonemal dynein, which is a component of sperm flagella. These data indicate that axonemal dynein expression starts in spermatocytes and is regulated by FSH
