Neurohormonal regulation of metabolism and ageing in the heart and brain
The X-Signaling lab
The X-Signaling lab
We are a part of the UCLA Cardiovascular theme and metabolic theme. Dr. Xiang is a member of the UCLA MCIP and Neuroscience Gratudate Program.
Our lab investigates diabetes and metabolic disorders in the settings of obesity and ageing, focusing on the links to cardiovascular and neurodegenerative diseases. Using tools ranging from stem cells, single-molecule imaging, genomics and proteomics, to whole-animal genetic models, we aim to uncover mechanisms and develop innovative therapies for conditions such as diabetes, heart failure, and Alzheimer’s disease.
