近年来,合成生物学已经成为一门新的学科,传统上由电子设备执行的功能被“细胞设备”取代,细胞设备是由生物部分(又名生物部分)构建的DNA基因编码电路。蜂窝设备可以用于感知和响应自然和人工信号。然而,该领域的一个主要挑战是,许多细胞信号通路之间的串扰使用相同的信号内源分子,可能导致不希望看到的激活。为了克服这个问题,我们利用了一种特定的启动子,它可以激活具有天然、无毒配体的基因,在低背景或不希望看到的非靶标表达的高诱导转录水平上。在这里,我们使用了孤儿芳香烃受体(AHR),这是一种配体激活的转录因子,激活后与细胞色素P450家族1,A亚家族多肽1(CYP1A1)启动子的特定AHR反应元件(AHR)结合。黄酮类化合物已被鉴定为AHR配体。这里提供的数据显示,成功地创造了一种合成基因“关闭”开关,可以使用光学报告基因直接进行监测。这是对合成的纳米级生物部分进行生物工程的第一步,用于构建分子事件传感器。
In recent years, Synthetic Biology has emerged as a new discipline where functions that were traditionally performed by electronic devices are replaced by “cellular devices”; genetically encoded circuits constructed of DNA that are built from biological parts (aka bio-parts). The cellular devices can be used for sensing and responding to natural and artificial signals. However, a major challenge in the field is that the crosstalk between many cellular signaling pathways use the same signaling endogenous molecules that can result in undesired activation. To overcome this problem, we utilized a specific promoter that can activate genes with a natural, non-toxic ligand at a highly-induced transcription level with low background or undesirable off-target expression. Here we used the orphan aryl hydrocarbon receptor (AHR), a ligand-activated transcription factor that upon activation binds to specific AHR response elements (AHRE) of the Cytochrome P450, family 1, subfamily A, polypeptide 1 (CYP1A1) promoter. Flavonoids have been identified as AHR ligands. Data presented here show the successful creation of a synthetic gene “off” switch that can be monitored directly using an optical reporter gene. This is the first step towards bioengineering of a synthetic, nanoscale bio-part for constructing a sensor for molecular events.
