| Abstract | To investigate the regulation of Ets family transcription factors Ets1 and Ets2 on the development of mouse testis and elucidate the effects of Ets1 and Ets2 on self-renewal and differentiation of spermatogonial stem cells. Mouse testis tissues were collected from specific developmental stages including the postnatal days 1, 5, 10, 15, 20, 25, 30, 35, 40, 50 and 70; busulfan peritoneal injection was performed and mouse testis tissues were collected on the 0th, 3rd, 5th, 8th, 10th, 18th days after injection respectively. The mRNA expression levels of Ets1 and Ets2 in samples were analyzed by semi-quantitative RT-PCR. The expression of Ets1 was significantly higher during the period of postnatal 1∼30 day than that at postnatal day 35 (P<0.05 or 0.01), while its expression decreased evidently and maintained at a stable level afterwards. Ets2 expressed significantly higher during the period of postnatal 1∼25 day than that at postnatal day 35 (P<0.05 or 0.01), while it decreased significantly and maintained at a stable level afterwards similarly. After busulfan treatment, the expression of Ets1 declined and reached the lowest level at day 5, then increased gradually and reached the level of day 0 after busulfan treatment and maintained steadily around day 9. Notably, the expressions of Ets1 at day 5 and day 8 were significantly higher than that of day 0 after busulfan treatment (P<0.05 or 0.01). No obvious changes was observed for the expression of Ets2 during 1∼9 day after busulfan treatment, while it decreased dramatically at day 10, which was significantly lower than that of day 0 and day 18 (P<0.05 or 0.01). The expression of Ets2 gradually increased after day 10 and reached its normal level around day 18. Taken together, Ets1 and Ets2 may affect the early development of mouse testis, adult spermatogenesis, as well as the proliferation and differentiation of spermatogonia. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
