Xiping Cheng completed her PhD in 2003 at the 4th Military Medical University, China.After several years of research on chronic pain and spinal cord regeneration at the 4th Military Medical University, she continued her postdoctoral studies at the University of Michigan where she focused on investigating calcium channels, their dysfunction in humandiseases, and the treatment of these diseases by manipulating channel functions.One of her studies focused on the role of a temperature-sensitive Ca2+-permeable channel-TRPV3 showed that TRPV3 can form a complex with the epidermal growth factor receptor (EGFR) to regulate proper formation of skin and hair (Cell. 2010, highlighted by Cell and Science Signaling). Later on, she discovered that TRPML1 KO mice exhibit primary, early onset muscular dystrophy. Her study showed that TRPML1, a lysosome Ca2+ channel, is crucial for muscle sarcolemma resealing (Nature Medicine, 2014). Currently at Regeneron, she is studying the role of endolysosomal system in muscle and metabolism diseases.


Research Interest

Intracellular calcium signaling and endolysosomal system using multidisciplinary approaches including mouse genetics, biochemistry, cellular and molecular biology, and live imaging. Her research focused on a better understanding of lysosome dysfunction in human diseases and the treatment of these diseases by regulating lysosome function
