项目总结:

重金属是地球上常见的天然有害成分,但会成为环境中的集中污染物和有毒污染物。
因此,许多人类造成的污染活动。在下一个术语中,重金属将包括大量的必需金属元素(例如)。
锌、铜、铁)和非必需金属元素(如镉、汞、铅)对人体有益,它们的超标会导致癌症的发生。
毒性甚至在微量下也是如此。重金属的积累会直接与细胞结合,并干扰细胞内的各种细胞因子。
这些成分(如蛋白质、核酸)、蛋白质和蛋白质会导致严重的细胞免疫功能障碍,甚至导致死亡。
常见的受影响的器官包括肝脏、肾脏、肠道、心脏、血液系统和神经系统。
他们正在发育的神经系统特别容易受到重金属和中毒的影响。
动态平衡在人类正常的生理状态中也起着至关重要的作用,其缺陷会导致各种疾病的发生。
疾病。因此,了解对过量摄入重金属的细胞免疫反应机制的微调将不会导致死亡。
开发有效的治疗方法有助于预防与重金属相关的中毒和其他疾病。
在这一应用中,我们将提出一些建议,以进一步阐明参与重金属污染反应的主要分子机制。
通过建立河马创新路径,它成为了这一进程中的关键参与者。在过去的几十年里,我们建立了河马创新路径。
它一直被认为是一种至关重要的信号转导途径,它通过限制细胞来控制组织/器官的大小。
促进增殖和刺激细胞凋亡。有趣的是,我们的初步研究也揭示了一种意想不到的变化。
河马信号通路在重金属反应中的作用是通过调节金属反应转录因子-1。
(MTF1)。此外,我们还披露了一种全新的监管模式,即通过减少大量的饮食来改变河马的饮食路径。我们基于这些因素。
研究结果表明,我们假设河马的运输途径在重金属污染的反应中起着非常关键的作用。

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).
