Opportunistically expressed (usually at the basal levels of transcription), but still permit the continued expression of genes that are regulated by strong promoters/enhancers (such as housing-keeping gene), the expresison of these genes might play a key role in the embryonic development; 5 The sum of these two opposing processes-activation and repression-would dictate the final pattern of gene expression that manifests itself as a dramatic reprogramming of gene expression during the maternal-to-zygotic transition and support further embryonic development.

这些基因的表达对于胚胎的后继发育可能是至关重要的；5）通过胚胎基因表达的激活与抑制：这两个作用相反的机制依不同时间顺序协同作用于胚胎基因，从而在指导胚胎发育的控制权由母源性表达产物移交到胚胎特异的基因表达产物的过程中&再程序化&胚胎基因的表达，形成特定的表达模式，以支持胚胎的后继发育。

Estrogen can effectively prevent bone loss by inhibiting osteal formation and resorption and decreasing bone transformation in ovariectomized rats, which may be related to the increased transcription of renal VDR.

Methods: The mRNA expressions of VEGF, kinaseinsert domain-containing receptor and fms-like tyrosine kinase1 (flt-1) in the tubal pregnant decidual tissue, the normal oviductal tissue and the early pregnant human endometrial decidual tissue were detected and compared with semiquantitative reverse transcription polymerase chain reaction.

采用半定量RT-PCR方法，检测输卵管妊娠蜕膜组织中的VEGF、KDR、Flt-1 mRNA的表达，并与正常输卵管黏膜及正常宫内早孕子宫蜕膜组织比较。

P16 gene is composed of two intervening sequences and three exons , and encodes p16 protein , which is the inhibiter of CDK4 and CDK6 . They can together prevent phosphorylation deactivation of pRB , and make the cell cycle blocked in G1 stage. P16 gene promoter region has a great of CpG islands , which can be methylated when some adverse factor appears , and so the genetic transcription of p16 can be inhibited , which leads to gene silencing, cell paraplasm, and tumor generate.

抑癌基因p16编码蛋白P16 ，是细胞周期蛋白CDK4和CDK6抑制剂，它阻止pRB磷酸化失活，使细胞周期阻滞于G1期。P16基因启动子区域富含CpG岛，当受到各种有害因素影响时，容易发生甲基化，从而抑制P16基因转录，导致基因沉默，细胞异常增生，导致肿瘤的发生[5]。

There was no identical proteins in the database we searched, but it shared high sequence homology with PNZIP from Pharbitis nil and two other open reading frames of unknown function from Synechocystis spp and Porphyra purpurea. These together defined a new family of evolutionarily conserved leucine zipper proteins, which might play a role as a transcription factor in the regulation of gene expression.
