| 摘 要： | 利用反义ＲＮＡ抑制基因表达的技术，发现ｃｙｃｌｉｎＥ基因在表达受到抑制后，乳腺癌细胞增殖速率和致癌性明显下降，结果还表明ｃｙｃｌｉｎＥ基因的抑制，可使ｐ２１＾ｗａｆｌ的转录水平上升，由此说明ｃｙｃｌｉｎＥ的异常与乳腺癌的发生有着密切的关系，在细胞周期调控上ｐ２１＾ｗａｆｌ的转录受到ｃｙｃｌｉｎＥ表达水平的明显影响。

| Abstract: | The elemental composition is analysed of sporus in twelve species of Selagneilla by X ray microanalysis in the scanning electron microscope. Seven elements, namely, Mg, Si, P, S, Cl, K and Ca, are found in the small sporus whereas Mg, Si, S, K and Cu exist in the large sporus. In the small sporus P, Cl, Al, Fe and Cu are rarely detected, however, Al, P and Fe are seldomly observed in the large sporus. The results show that among different species the amount of the same element is quite different and in same species the elemental composition and amount vary considerably. |
