Summary
Systems biology integrates complex biological systems to understand circadian rhythms and their links to diseases. Lifestyle significantly impacts these rhythms, influencing health and disease development through gene expression networks.
Area of Science:
- Integrative biology and systems biology approaches.
- Understanding complex biological systems and decoding life.
- Multiscale phenomena of circadian rhythms.
Background:
- Circadian rhythms influence gene expression, metabolism, and behavior.
- Circadian control systems involve feedback loops of core proteins.
- Disrupted circadian rhythms are linked to diseases like obesity and cancer.
Purpose of the Study:
- To review the relationship between circadian control systems and diseases.
- To explore the role of systems biology in understanding circadian rhythm disorders.
- To highlight the impact of lifestyle on circadian rhythm and health.
Main Methods:
- Utilizing systems biology approaches: genomics, transcriptomics, proteomics.
- Analyzing interactions between circadian control systems and diseases.
- Reviewing studies on circadian rhythm disorders and associated genes/proteins.
Main Results:
- Complex interactions between circadian control and diseases are delineated.
- Circadian core proteins regulate gene expression via feedback loops.
- Lifestyle is a key factor modifying circadian rhythm and disease risk.
Conclusions:
- Systems biology provides a framework for understanding circadian rhythm disorders.
- Disruption of circadian rhythms is associated with various pathologies.
- Gene expression networks modulated by lifestyle are crucial in circadian health and disease.

4.7K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.

The cell cycle regulation directs how a cell proceeds from one phase to the next and begins mitosis. The cell cycle control system includes intracellular regulatory molecules and external triggers. They provide "stop" or "advance" signals and operate at specific cell cycle stages termed checkpoints to ensure that a particular process is completed before the cell advances to the next phase.

The cell cycle is an organized set of events that leads the cell to divide into two daughter cells, each containing chromosomes identical to the parent cell. It is the cell cycle that leads to the formation of an entire organism from a single-cell zygote. Besides, cell division also functions in the renewal or repair of tissues in adult multicellular eukaryotes. For example, in the bone marrow, the stem cells divide to form new blood cells. Although essential for several functions, cell...
