| 7. | The two single - pass transmembrane proteins , delta and serrate , have been identified as notch ligands . the transcription factor suppressor of hairless [ su ( h ) ] is the major downstream effector of notch signaling pathway . rbp - j , the mammalian homolog of su ( h ) , recognizes the core sequence ( c / tgtgggaa ) of dna
Rbp - j是果蝇促神经发生基因su ( h ) ( suppressorofhairless )在哺乳动物的同源物，它通过其识别序列( c tgtgggaa )结合于受调控基因的启动子区，在转录激活因子的驱动下调节细胞分化和个体发育相关基因的表达。
|
| 8. | The tumor cells transfected with restin are arrested in gl phase and the cell proliferation is inhibited . it implies that restin may be correlated to cell cycle regulation . other data showed that the necdin , a homolog of restin , could suppress cell growth by interacting with transcription factor e2f1 and p53
而与restin的同源蛋白的necdin ，可以与细胞周期促进蛋白sv40大t抗原、腺病毒eia 、转录因子ezfi等相互作用，抑制细胞生长;也可以和转录因子p53作用参与生长抑制和抑制p53诱导的细胞凋亡。
|
| 9. | Many studies show that leafy is high homolog even among distantly related plant species . exception of these , little studies on tissue culture and transformation of ginkgo have been done . this paper emphasizes on the isolation , cloning and analysing two ginkgo orthologs of leafy from the male tree
为此，本实验从银杏leafy同源基因的克隆入手，分析其雌雄株lfy基因结构差异，构建lfy基因的植物正义反义表达载体，建立矮牵牛遗传转化体系，以研究银杏lfy同源基因的功能，同时建立了银杏组织培养体系，为银杏的遗传转化和提早开花结果奠定基础。
