Studies also indicated that genistein exsists not only in soybeans but also in many kinds of plants such as vegetables and fruits.As a potential anticancer agent, the actional mechanisms of genistein mainly includes as follows:First, genistein can depress the activity of protein tyrosine kinase and transduction pathways for the phosphorylation of receptors and mitosis signal. So genistein can lead to cells' proliferation depressed. Second, genistein has minimal effects of phytoestrogens. It can be combined with estrogen receptor and improve the synthesis of cellular sex hormone binding glulobin, and improve the activity of UDP-glucuronyl transferase. Through these pathways, it can inhibit the cell activity of breast cancer and prostate cancer.

作为一个很有潜力的抗肿瘤物质，三羟异黄酮的作用机制主要包括：①抑制蛋白酪氨酸激酶活性，可阻抑PTK引起的受体磷酸化和有丝分裂的信号传递，导致癌细胞增殖受抑；②弱雌激素作用：可通过与体内雌激素受体结合，并可增加细胞内性激素结合球蛋白的合成，增加UDP-葡糖醛酸转移酶的活性等途径抑制乳腺癌和前列腺癌细胞活性；③拓扑酶Ⅰ和Ⅱ抑制剂，抑制细胞活性；④上调细胞周期性负性调节因子P21WAF1/CIP1的表达，使之负性调节因子作用增强；⑤可阻止胰岛素样生长因子-Ⅰ、肝细胞生长因子和神经生长因子的作用而抑制肿瘤生长；⑥其他：抗氧化作用、抑制热休克蛋白、诱导细胞凋亡、抑制新生血管生成和抑制多种耐药相关蛋白等。

The results suggest the expression of Nm23-〓 Protein is more often seen in the cases of adenosis with atypical hyperplasia than in the cases of carcinoma, the expression of Nm23-〓 might be a marker of adenosis with atypical hyperplasia in cases of FCD; Lower level of Nm23-〓 suggests in had a high metastatic potentiality in breast cancer.

在浸润性导管癌组中，有腋窝淋巴结转移组的Nm23-〓含量显著低于无液窝淋巴结转移组。结果提示：Nm23-〓蛋白在不典型增生上皮中的表达比癌组织更常见，Nm23-〓蛋白过度表达可能是乳腺上皮不典型增生的一个特征；在乳腺癌病例中，Nm23-〓蛋白表达与腋窝淋巴结状态有关。

The results demonstrate that a greatly increased bioavailability of As under the flooded conditions is the main reason for an enhanced As accumulation by flooded rice, and growing rice aerobically can dramatically decrease the As transfer from soil to grain.

这两种硅运输蛋白都在根部表达，其中一种称为Lsi1的蛋白是亚砷酸盐进入水稻的门户，而另一种称为Lsi2的蛋白控制着从根部到茎再到谷粒的流动。这组研究者还发现硅酸—含有硅、氢和氧—会干扰亚砷酸盐的摄取。他们提出，增加土壤中可利用的硅，可能会减少从土壤和灌溉用水到水稻的砷的运输。（生物谷Bioon.com

Neuroglobin, a recently identified monomer globin in nerve system, is highly affinitive with oxygen similar to myoglobin. After the coding region of rat NGB gene was sub cloned into the prokaryotic expression vector pGEX 4T 2, the recombinant vector was introduced into E. coli BL21 (DE3) cells for efficient expression.

氧是人类及许多生物赖以生存的重要条件，严重缺氧和低氧可危及人体生命。2 0 0 0年 9月，德国Burmester等人首次报道了人和小鼠脑内存在特异的功能上类似于肌红蛋白的携氧蛋白———脑红蛋白(neuroglobin ，NGB) [1 ] 。

Staining for agrin, the major HS proteoglycan core protein in the GBM, was unaltered.

而GBM内主要的HS蛋白多糖核心蛋白—集聚蛋白染色没有变化。
