Outline of Final Research Achievements |
We examined the role of nitric oxide (NO) on apoptosis and S-nitrosylation that might affect apoptosis. To inhibit NO production, pregnant rats were administered an NO synthase inhibitor, L-NAME, apoptotic cells were observed in the endometrium of L-NAME-treated and -untreated rats. L-NAME-treatment significantly increased apoptosis and the expressions of cleaved-caspase-3 and X-linked inhibitor of apoptosis (XIAP), but significantly decreased thioredoxin (Trx) -1. Furthermore, L-NAME-treatment significantly induced S-nitrosylation (SNO) of cleaved caspase-3 and XIAP that were associated with a marked decline in Trx-1. These results suggest that apoptosis in the endometrium is positively and negatively regulated by NO through caspase and its inhibitor and S-nitrosylation of those factors during mid-gestation.
