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).
