| Research Abstract |
1. We cloned and sequence a DIG-1 gene that specifically expressed by thymocytes after dexamethason(DEX)treatment.
2. DIG-1 gene encodes 7 transmembrane G protein coupled receptor.
3. We have established 3 lines of DIG-1 transgenic mice.
4. In transgenic mice, thymus were significantly smaller than those in control mice. After DEX injection, the apoptotic cells within thymic cortex increased siginificantly as compared to those in control mice. The apoptotic cells were mainly CD4+CD8+ thymocytes.
5. The expression of apoptosis-related proteins, Bcl-2 and BAX were not significantly different from thosse in transgenic mice.
