-estradiol 和 flavone 對 SC-M1 細胞基 因表現的影響

利用 mRNA 鑑別展示(DD RT-PCR)找出所有受藥物影響的基因接著將有差 異的 band 取下後進行核酸序列分析。如表六及表七是經 NCBI 基因庫比對之結 果。如 Figure 54 至 Figure 59 及表六結果顯示胃癌細胞受 17

α

-estradiol (E2)影響 的基因共有 32 個,有 12 個基因被誘導表現,有 20 個基因表現被抑制,其中 9 個基因是未知的。受 flavone 影響基因共有 22 個,有 5 個被誘導表現,有 17 個 基因被抑制其中有 3 個是屬於未知的基因。如 Figure 60 至 64 及表七受 apigenin 影響的基因共有 47 個基因,有 25 個被誘導表現,有 22 個基因被抑制其中有 17 個是屬於未知的基因。

2. 檢測 17

α

-estradiol 對 SC-M1 細胞的細胞膜上 Oncostatin M receptor 的影響 由 DD RT-PCR 結果 Figure 54、56 和 Table 6 發現 17

α

-estradiol 可以誘導 Oncostatin M receptor 基因的表現,因此我們利用抗體檢測 17

α

-estradiol 是否真的 會增加細胞膜上 Oncosatin M receptor 的表現,而結果與 DD RT-PCR 結果是相符 合。

3. 加入 p38 MAPK 抑制劑 SB 203580 和 MAPK/ERK kinase I 抑制劑 PD 98059 檢測對人類胃癌細胞株 SC-M1 的存活率的影響,由 Figure 66 結果發現在有先加 入 10

µ

M SB 203580 作用 3 小時後的細胞存活率增加 6 %,因此推論 17

α

-estradiol 是藉由 oncostatin M receptor 下游訊息調控路徑 p38 MAPK 來導致人類胃癌細胞 株 SC-M1 產生細胞凋亡。
