Abstract
Daily rhythms in behavior, physiology, and metabolism are an integral part of homeostasis. These rhythms emerge from interactions between endogenous circadian clocks and ambient light-dark cycles, sleep-activity cycles, and eating-fasting cycles. Nearly the entire primate genome shows daily rhythms in expression in tissue- and locus-specific manners. These molecular rhythms modulate several key aspects of cellular and tissue function with profound implications in public health, disease prevention, and disease management. In modern societies light at night disrupts circadian rhythms, leading to further disruption of sleep-activity and eating-fasting cycles. While acute circadian disruption may cause transient discomfort or exacerbate chronic diseases, chronic circadian disruption can enhance risks for numerous diseases. The molecular understanding of circadian rhythms is opening new therapeutic frontiers placing the circadian clock in a central role. Here, we review recent advancements on how to enhance our circadian clock through behavioral interventions, timing of drug administration, and pharmacological targeting of circadian clock components that are already providing new preventive and therapeutic strategies for several diseases, including metabolic syndrome and cancer.

Figure 1.. Circadian rhythms emerge from multiple factors including the circadian clock.
Schematic organization of various factors that interact to produce daily rhythms in behavior, physiology and metabolism. Network of cell autonomous circadian oscillators in the suprachiasmatic nucleus (SCN) directly or indirectly communicates with peripheral circadian clocks through neural communications, endocrine agents and body temperature rhythms. Both SCN and peripheral clocks interact to produce daily rhythms in sleep, physical activity, and nutrition metabolism, each of which can also feedback to central or peripheral clocks. Overall, both SCN and the peripheral circadian oscillators are influenced by ambient light-dark cycle.
Figure 2.. Hallmarks of circadian regulation.
A. The genetic code denotes the set of protein coding genes in the genome. The epigenetic code instructs the expression of a subset of genes in the genome to be expressed in a given tissue that determines the tissue identity and function. Similarly, the circadian code instructs a subset of transcripts in every given tissue to be temporally regulated. The ensemble of rhythmic transcripts in different tissues determine the diurnal rhythms in physiology, metabolism and behavior. B. Functional annotation of rhythmic transcripts has revealed some of the basic cellular processes are circadianly modulated in multiple tissues. Some of these processes are depicted below.
Figure 3.. Circadian rhythm disruption and diseases across lifespan.
CRD can manifest in different diseases and disorders during the lifespan of an individual. In early childhood, disruption of the rhythm can cause irritability, mood swings and fatigue that can lead to impaired growth and development in extreme cases. As we age, chronic circadian rhythm disruption continuing over several weeks or months can cause mild disorders like fragmented sleep and compromised learning to an increased risk for a number of chronic diseases, including Type2 diabetes, Alzheimer’s etc. While milder forms of the diseases can be alleviated by behavioral adjustments to improve circadian rhythms, optimal timing of existing drugs or even pharmacological targeting of circadian clock components hold promise for treating some of the severe chronic diseases.
