Abstract:
Immunohistological detection of each of the four Id proteins (Id1-Id4) in sections of mouse testis revealed a unique temporal and spatial expression pattern for each Id protein during spermatogenesis. Furthermore, each Id protein displayed a distinctive, dynamic pattern of subcellular distribution. Id1 was uniquely expressed in MI/MII spermatocytes undergoing meiotic division. Id4 protein was detectable in the cytoplasm of type A1 spermatogonia, as well as in late pachytene and in diplotene spermatocytes. Id2 protein, which was most abundant in Sertoli cell nuclei, was also detectable in pachytene and diplotene spermatocytes, but as with Id4, it was absent from MI/MII cells. In postmeiotic spermatids, Id1, Id2, and Id4 proteins were expressed in a stage- and subcellular-specific manner. Expression of Id3 was restricted to Sertoli cell cytoplasm. In malignant seminoma cells, all four Id proteins were abundantly expressed with accompanying changes in their subcellular distribution. The observed expression of Id proteins in postproliferative Sertoli cells and spermatids and during specific stages of meiosis implies novel functional roles for this class of transcriptional regulator during spermatogenesis.
