초록

Purpose : To address the ability of Olibanum to induce cell death, we investigated the effect of olibanum on cell apoptosis. Twenty-four hours later, apoptosis occurred following olibanum exposure in a dose-dependent manner. Methods : We culture HeLa cell which is human metrocarcinoma cell in D-MEM included 10% fetal bovine serum(Hyclone Laboratories) below $37^{\circ}C$, 5% CO2. Then we observed apoptosis of log phage cell which is changed cultivation liquid 24 Hours periodically. Results : The treatment of BAPTA-AM regulated olibanum-induced apoptosis in HeLa human cervical carcinoma cells. The 24 hr-earlier -thapsigargin-pretreated cell showed the resistance against olibanum-induced apoptosis and the Ru360-mitochondrial uniporter-inhibited olibanum-induced apoptosis, too. It means that olibanum leads to the accumulation of calcium and the resultant apoptosis in HeLa cells. Immunoblotting data also shows that the expression of GRP78, ER stress marker protein, was induced by the olibanum. Bcl-2, anti-apototic protein, was decreased and that the expression of Bax, pro-apoptotic protein, was increased by the addition of olibanum. Interestingly, the olibanum increased the activity of caspase-8 as well as calpain cysteine pretense in HeLa cervical carcinoma cells. Calpain inhibitor-calpastatin as well as caspase-8C/A expression abrogated olibanum-induced apoptosis in the carcinoma cells. The inhibition of caspase-8 regulated olibanum-induced calpain activation but the inhibition of calpain did not have any effect on the caspase-8 activation in HeLa human cervical carcinoma cells. Conclusion : We conclude that olibanum induces the accumulation of calcium and the resultant apoptosis in which caspase-8 and calpain are involved.
