中文摘要
项目摘要
重金属是地球上的天然成分,但在环境中会富集并产生毒性
是人类活动的结果。 术语重金属包括许多必需金属(例如,
锌、铜、铁)和非人体必需金属(如镉、汞、铅),其过量会导致
微量也有毒性。积累的重金属直接结合并干扰各种细胞
这类疾病会导致细胞内的蛋白质、核酸等多种成分受损,并导致严重的细胞功能障碍,甚至死亡。 最
通常受影响的器官包括肝、肾、肠、心脏、血液和神经系统。 儿童
他们发育中的神经系统特别容易受到重金属中毒的影响。 重金属
内稳态在人类正常生理中也起着重要作用,其缺陷导致各种人类
疾病因此,了解细胞对过量重金属的精细调节反应将导致
重金属中毒及相关疾病的有效治疗方法。
在本应用中,我们建议阐明参与重金属响应的分子机制
通过建立河马途径作为这一过程中的关键参与者。在过去的几十年里,河马路径
已经被认为是通过限制细胞生长来控制组织/器官大小的关键信号通路。
增殖和刺激细胞凋亡。有趣的是,我们的初步研究揭示了一个意想不到的
Hippo信号通路通过调控金属离子应答转录因子1在重金属应答中的作用
(MTF 1)。此外,我们还发现了一种新的调节河马途径的沉重的膳食。基于这些
研究结果,我们推测,海马途径在重金属反应中起着至关重要的作用。 在这
应用,我们提出1)表征Hippo途径-重金属介导的体内重金属反应(目的1);
2)阐明Hippo通路对MTF 1的调节(目的2); 3)研究Hippo通路对MTF 1的调节,
重金属的Hippo途径(目标3)。
英文摘要
PROJECT SUMMARY
Heavy metals are natural components in the earth but become concentrated and toxic in environment
as a result of human-caused activities. The term heavy metals comprise a number of essential metals (e.g.
zinc, copper, iron) and non-essential metals (e.g. cadmium, mercury, lead) for human, whose excess results in
toxicity even under trace amount. Accumulated heavy metals directly bind to and interfere with various cellular
components (e.g. proteins, nucleic acids), and lead to severe cellular dysfunction and even death. The most
commonly affected organs include liver, kidney, intestine, heart, blood and nervous systems. Children with
their developing nervous systems are particularly vulnerable to heavy metal intoxication. Heavy metal
homeostasis also plays an essential role in human normal physiology, whose defect results in various human
diseases. Therefore, understanding the fine-tuned cellular response to overdosed heavy metals will lead to the
development of effective therapeutic methods against heavy metal-associated intoxication and diseases.
In this application, we propose to elucidate the molecular mechanism involved in heavy metal response
by establishing the Hippo pathway as a key player in this process. Over the past decades, the Hippo pathway
has been recognized as a crucial signaling pathway that controls tissue/organ size by restricting cell
proliferation and stimulating cell apoptosis. Interestingly, our preliminary studies have revealed an unexpected
role of the Hippo pathway in heavy metal response by regulating metal-responsive transcription factor 1
(MTF1). Moreover, we have revealed a novel regulation of the Hippo pathway by heavy meals. Based on these
findings, we hypothesize that the Hippo pathway plays a critical role in heavy metal response. In this
application, we propose 1) to characterize the Hippo pathway-mediated heavy metal response in vivo (Aim 1);;
2) to elucidate the regulation of MTF1 by the Hippo pathway (Aim 2);; and 3) to study the regulation of the
Hippo pathway by heavy metals (Aim 3).
