研究生殖细胞中的基因表达有助于阐明转录调控机制,因为不同的基因在雄性和雌性生殖细胞中被激活。卵母细胞特异性基因Oog1的启动子区域已经被表征。利用这些不同的启动子区域驱动绿色荧光蛋白的表达为我们提供了基因表达调控的重要信息。这个3.9 kb长的启动子在转基因小鼠的雄性和雌性生殖细胞中都起作用。这种两性二态性表达的原因是什么?在这个3.9 kb的启动子区域内外可能存在重要的因子,这些因子是维持适当的性别特异性基因表达所必需的。
Studying gene expression in germ cells is useful for elucidating mechanisms of transcriptional regulation, because different genes are activated in male and female germ cells. The promoter regions of an oocyte-specific gene, Oog1, have been characterized. Driving the expression of green fluorescent protein with these different promoter regions provided us with critical information on the regulation of gene expression. The 3.9 kb long promoter functions in both male and female germ cells in transgenic mice. What is the cause of this sexually dimorphic expression? There may be important factors within and perhaps also outside this 3.9 kb promoter region that are required to maintain proper sex-specific gene expression.
