The expression of Bcl-2 was weak or negative; there is no difference among various groups.Research Conclusion: lCadmium can accelerate the apoptosis of GCs and is related with dose; 2Cadmium accelerate atresic of follicular; and increase the number of interstitial gland;3Cadmium enhance the expression of bax, and no affect obviously on bcl-2;4 Selenium restrained the effect of cadmium-induced apoptosis on granulosa cells, but it cant be interdicted completely.

实验结论：1 镉能促进小鼠卵巢颗粒细胞凋亡，并具有剂量效应关系。2 镉能促进卵泡闭锁，使卵巢间质腺数量增加。3 镉能增强颗粒细胞凋亡相关基因bax的表达，对bcl-2的表达则无明显影响。4 硒具有一定的抑制镉致颗粒细胞凋亡的作用，但不能完全阻断。

Similar patterns of changes in Sox2 expression and in bFGF expression were observed in atrophic retina and in injured retina.

在萎缩的视网膜和损伤的视网膜中发现了Sox2和bFGF表达变化中的相似模式。

This principle concerns about that if it is hard to make difference from the factors of awork expressed and the ideas embodied by the expression , or that the factors expressed in a work is so limited that the same orsimilar expression of others does not constitute an infringement of copyright.

合并原则关注的是作品的表达性成分和作品表达体现的思想是否难以区分，或者表达性成分很有限以致他人的相同或相似的表达不构成侵权。

The expression of Bax and Bcl-2 in cerebellum cortex and bathypelagic nuclei of the ovariectomized SD rat were up-regulated and down-regulated respectively, and the expression of the 2 proteins was regulated to normal after the rats were treated with 17β-estradiol.

结果显示，摘除双侧卵巢后，SD大鼠小脑皮质及深层核团中Bcl-2的表达有不同程度的降低，而Bax的表达出现不同程度的上升；给予外源性17β-雌二醇治疗后，2种蛋白的比例基本恢复正常。

Bi-allelic or biparental expression of alleles may be present in some tissues and uniparental expression in other tissues.

某些组织中可能出现等位基因的双等位基因或双亲表达，其他组织中是单亲表达。angelman综合征和prader-willi综合征都可因第15号染色体缺失而产生。

One was the pqsA' positive expression plasmid constructed by cloning the pqsA'-lacZ fusion digested from pYHP441 into miniCTX-1, whose sequence was then integrated into wild type PAO-1 chromosome by biparental mating procedure. The other was pqsA-E operon knock-out plasmid whose sequence between pqsD and pqsE operon was inserted by tetracycline cassette by the site specific insertion mutagenesis strategy and the mutant constructed by biparental mating of S17-1 that harbored the plasmid and pqsA' positive expression mutant.

一种是酶切质粒pYHP441获得pqsA'-lacZ片段后，亚克隆入质粒miniCTX-1中，构建成PqsA'的阳性表达质粒，随后将构建的质粒，通过双亲交配过程整合入野生型铜绿假单胞菌株PAO-1染色体组中；另一种是通过点特异插入诱变策略，将四环素基因盒插入启动子pqsD和pqsE之间，构建的阴性质粒转化入大肠杆菌S17-1株后，和上述pqsA'阳性表达突变株进行双亲交配过程。

In the NPC cell lines,loss of BLU expression correlated with hypermethylation of the 20 CpG sites in the 5′ region of BLU(approximately -292bp to -23bp upstream the translation start site)as revealed by bisulphite sequencing. Expression of the gene was restored aftertreatment with 5-aza-2-deoxycytidine in CNE2, suggesting that repression of BLUtranscription might at least be partially mediated by promoter methylation.

结果显示，BLU基因翻译起点ATG上游-292--23bp区间内的20个CpG位点在5例细胞系中均被完全或者部分甲基化，与基因的表达缺失呈负相关关系；去甲基化试剂5-Aza-CdR处理CNE2后基因表达部分恢复，说明甲基化至少是引起BLU基因转录抑制的部分原因。

It also indicates that the expression of WT1 is regulated strictly in time and space, and the aberrant expression of WT1 may result in retarded differentiation of blastemal cell leading NR or nephroblastoma.

提示在散发性肾母细胞瘤发生中除WT1突变外，WT1表达延迟可能是其中起重要作用的机制之一；WT1基因与肾母细胞瘤的组织分化有关，可能诱导胚基细胞向上皮细胞方向分化。
