EST similarity analysis was finished by comparing sequences with BLASTx searches in NCBI. The results showed that they are proteins involved in biological processes such as energy metabolism and RNA molecular level regulation. Some of them are enzymes and structural proteins in the cell. This study provides useful information for future studies on molecular mechanism of filament coloring and for breeding new silkworm variety that spin color cocoons.

通过BLAST比对和对所得表达序列标签的同源分析表明，这些基因主要涉及能量代谢因子、RNA分子水平相关调节因子、酶类、结构蛋白等，由此初步探明了参与黄血基因协同作用的相关基因表达蛋白的种类和数量，可为进一步研究蚕茧着色的分子机制及通过遗传选择培育天然有色茧品种提供基础信息。

Asian stem borer is polyphagic and has 2-3generations on different host plants in one year .whatmore ,the interactions between Asian stem borer and its hosts increase its genetic aberrance .

长期以来，二化螟给我国的水稻生产带来了严重的经济损失。二化螟食性杂，寄主范围广，与众多寄主存在复杂的交互作用使得其遗传差异变大。

The stable prostatic carcinoma cell subline highly expressingTSLC1 has successfully established, which provided a basis for further exploring the rolesof TSLC1 in prostatic carcinoma.

(1)成功建立了稳定表达TSLC1的T_3B细胞系，该细胞系遗传性质稳定，为进一步研究TSLC1在前列腺癌中发挥的作用奠定了基础。

Methods The triceps and subscapular skinfolds were measured and the body composition were estimated by using Changling's and Brozek's models in a total of 376 twin pairs of Han nationality,including 245 monozygotic and 131 likesex dizygotic twin pairs aged 6 to 18 years.Modelfitting method with Mx package was performed to evaluate the proportion of variance components and to analyze the effect of sex,age and development period on the skinfold thickness and body composition.

测量376对6～18岁同性别双生子(同卵245对，异卵131对)肱三头肌、肩胛下皮褶厚度，用长岭和Brozek公式估算体成分；用Mx软件拟合最佳模型，计算各指标遗传与环境方差组分，分析年龄、性别和不同发育期的作用。

It is more likely that an increased genetic susceptibility plays a role in the NAFLD.

很可能是强的遗传易感性在NAFLD中具有重要作用。

We summarized that CRC is a disease caused by synergism of environment and diet, life style and heredity.

结直肠癌是由环境、饮食以及生活方式与遗传因素协同作用的结果。
