Project description:Spermatogonial stem cells are foundation of spermatogenesis. In our previous study, we observed a rapid degeneration of spermatogenesis by conditional knockout (cKO) of Nanos2 in adult spermatogonia, but the underlying mechanisms are largely unknown. While, conditional overexpression (cOE) of Nanos2 also inhibited germ cell development and stayed in undifferentiation status. Here we used cultured germline stem cells (GSCs) to study the mechanisms of Nanos2 in spermatogonia. We compared Nanos2 expression in cultured GSCs with in vivo isolated Nanos2 positive cells, and found the level of Nanos2 is significantly lower in GSCs as compared to Nanos2 positive cells. Thus we generated Nano2 cOE GSCs lines. By conditional inducing expression of Nanos2 we compared gene expression profile to control GSCs. These data provide the first evidence of Nanos2 regulating genes in spermatogonial stem cells.

Project description:PURPOSE: To provide a detailed gene expression profile of the normal postnatal mouse cornea. METHODS: Serial analysis of gene expression (SAGE) was performed on postnatal day (PN)9 and adult mouse (6 week) total corneas. The expression of selected genes was analyzed by in situ hybridization. RESULTS: A total of 64,272 PN9 and 62,206 adult tags were sequenced. Mouse corneal transcriptomes are composed of at least 19,544 and 18,509 unique mRNAs, respectively. One third of the unique tags were expressed at both stages, whereas a third was identified exclusively in PN9 or adult corneas. Three hundred thirty-four PN9 and 339 adult tags were enriched more than fivefold over other published nonocular libraries. Abundant transcripts were associated with metabolic functions, redox activities, and barrier integrity. Three members of the Ly-6/uPAR family whose functions are unknown in the cornea constitute more than 1% of the total mRNA. Aquaporin 5, epithelial membrane protein and glutathione-S-transferase (GST) omega-1, and GST alpha-4 mRNAs were preferentially expressed in distinct corneal epithelial layers, providing new markers for stratification. More than 200 tags were differentially expressed, of which 25 mediate transcription. CONCLUSIONS: In addition to providing a detailed profile of expressed genes in the PN9 and mature mouse cornea, the present SAGE data demonstrate dynamic changes in gene expression after eye opening and provide new probes for exploring corneal epithelial cell stratification, development, and function and for exploring the intricate relationship between programmed and environmentally induced gene expression in the cornea.
