Purpose : 이 연구는 MCF-7 인간 유방암 세포주에 대한 활락효령단(活絡效靈丹) 추출물의 증식억제효과, 세포독성효과, 세포사 유발효과를 확인하기 위하여 이루어졌다. Methods : MCF-7 인간 유방암 세포주는 Dulbecco's modified Eagle's medium/F12 (DMEM/F12)에 10% fetal bovine serum (FBS)와 항생제를 가하여 만든 배지를 이용하여 배양하였고 MCF-7 세포를 96-well plate에 접종한 후 다양한 농도 (0 ${\sim}$ 2000 g/ml)의 활락효령단(活絡效靈丹)이 든 배지로 처리한 후 72시간 동안 배양하였고 또한 1000g/ml의 활락효령단(活絡效靈丹)이 든 배지로 처리한 후 48, 96, 192 시간동안 배양하여 각각 MTS assay kit로 세포생존율을 측정하였다. 세포독성은 Sulforhodamine B assay 방법을 이용해 측정하였고 세포사 과정에서 MCF-7 세포에서의 caspase 활성화를 측정하기 위해 Western blotting을 수행하여 poly ADP ribose polymerase (PARP)의 절단을 확인하였다. Results : 실험결과 활락효령단(活絡效靈丹) 추출물에 의한 세포성장 및 독성효과는 시간 및 농도에 비례하는 것으로 나타났고 세포고사과정에서 작용하는 caspase의 전기질인 PARP 절단량이 활락효령단(活絡效靈丹) 처리 농도에 비례에 증가하였다. Conclusions : 활락효령단(活絡效靈丹)은 다양한 기전에 의해서 유방암 세포에 대한 억제효과를 가질 수 있는 것으로 인식할 수 있다.

This experimental study was carried out to evaluate the effects of Hwallakhyoreungdan on angiogenic inhibition mechanism. In order to investigate the effects of Hwallakhyoreungdan on angiogenic inhibition mechanism, MTT assay, cell adhesive inhibition effect, DNA fragmantaion analysis, Nuclear condensation assay, FACScan analysis, Angiogenic lumen formation assay, Immunocytochemistry analysis, RT-PCR for mRNA expression, Western blot analysis and Confocal analysis for $Ca^{2+}$ change were performed. The results were summarized as follows: 1. The cell adhesive inhibition ability was strong from $5{\mu}g/ml$. 2. The $G_0/G_1$ arrest peak was existed on ECV304 cell-line. 3. The cells on Collagen plate were inhibition of proliferation and inducement of apoptosis by HR water extract. 4. Angiogenic lumen formation was inhibited by HR water extract. 5. LFA-1 and ELAM-1's expression were inhibited by HR water extract. They are commenly participation on inflammation and tumor regeneration. 6. The expression of MMP-9 and uPA were inhibited by HR water extract. 7. The expression of integrin ${\alpha}_v{\beta}_3$ was inhibited by HR water extract. 8. The expression of intracellular molecule were successively inhibited by HR water extract therefore the proliferation of ECV304 cell line was stopped and apoptosis was induced. 9. The change of $Ca^{2+}$ was decreased by HR water extract it cause confusion of signal transduction pathway therefore it was take part in apoptosis. According to the results, Hwallakhyoreungdan showed to be a key antaonist of integrin ${\alpha}_v{\beta}_3$, and to be induction of apoptosis by p53 through flow cytometry. This report also demonstrated that expressions of MMP-9 and uPA was blocked under the angiogenesis model. Thus, we suggests that Hwallakhyoreungdan blocks angiogenesis by inducing apoptosis of ECV304 and ECVPAR cell lines and another oriental herbal medicine that treats blood-stasis type also has angiogenic inhibition effects.
