Circadian rhythms play crucial roles in orchestrating diverse physiological processes that are critical for health and disease. Dysregulated circadian rhythms are closely associated with various human metabolic diseases, including type 2 diabetes, cardiovascular disease, and non-alcoholic fatty liver disease. Modern lifestyles are frequently associated with an irregular circadian rhythm, which poses a significant risk to public health. While the central clock has a set periodicity, circadian oscillators in peripheral organs, particularly in the liver, can be entrained by metabolic alterations or stress cues. At the molecular level, the signal transduction pathways that mediate stress responses interact with the key determinants of circadian oscillation to maintain metabolic homeostasis under physiological or pathological conditions. In the liver, a number of nuclear receptors or transcriptional regulators, which are regulated by metabolites, hormones, the circadian clock, or environmental stressors, serve as direct links between stress responses and circadian metabolism. In this review, we summarize recent advances in the understanding of the interactions between stress responses (endoplasmic reticulum stress response, oxidative stress response, and inflammatory responses) and circadian metabolism, and the role of these interactions in the development of metabolic diseases.
