The focus of Dr. Fleig’s research interest revolves around cellular signaling events as they relate to health and disease. Over the past 20 years, Dr. Fleig has been using biophysical and pharmacological approaches elucidating ion channel function and its relationship to cell signaling. Mediated by very rewarding collaborations she was able to incorporate molecular aspects to this work leading to the original identification and biophysical as well as functional characterization of several novel ion channels. One of these, TRPM7, has been implicated in anoxia-mediated cell death following ischemia and emerges as a key regulator of cell proliferation with therapeutic implications for cancer treatment. The results of Dr. Fleig’s work identified TRPM7 to be at the nexus of mechanisms that regulate both cellular and whole body magnesium homeostasis in mammals.
