STKE2006 Feb 21; 2006 AB - In mammals, circadian rhythms regulate many aspects of behavior and physiology, including sleep-wake cycles and metabolism. Disruption of these rhythms is associated with certain psychiatric illnesses such as bipolar disorder. Yin et al. describe a potential molecular link between circadian clock control and bipolar disorder. In cultured fibroblasts, a key negative regulator of clock gene expression, the Rev-erbα nuclear receptor, was rapidly degraded after exposure to lithium, which is used in treating bipolar disorder. This destabilization of Rev-erbα led to activation of clock genes. L. Yin, J. Wang, P. S. Klein, M. A.
