Summary
The circadian clock influences aging and cancer by regulating gene expression. Understanding its role may lead to new chronochemotherapy strategies and tissue rejuvenation for combating these diseases.
Area of Science:
- Molecular Biology
- Chronobiology
- Oncology
Background:
- The circadian clock, driven by transcription-translation feedback loops (TTFLs), regulates numerous physiological processes.
- Key clock proteins like BMAL1 and CLOCK control over 50% of human genes.
- Disruption of circadian clock function by the tumor microenvironment is implicated in tumorigenesis.
Purpose of the Study:
- To explore the complex relationships between the circadian clock, aging, and cancer.
- To discuss the hypothesis of relocalization of chromatin modifiers (RCM) in the context of circadian rhythm's role in aging and carcinogenesis.
- To introduce chromatin remodeling as a potential strategy for tissue rejuvenation against aging and cancer.
Main Methods:
- Literature review and hypothesis discussion.
- Analysis of the role of circadian rhythm in aging and carcinogenesis.
- Exploration of chromatin remodeling mechanisms.
Main Results:
- The circadian clock's TTFL mechanism is fundamental to biological rhythms.
- Tumor microenvironments can interfere with clock gene functions, promoting cancer.
- Chronochemotherapy optimization requires further justification.
Conclusions:
- Elucidating the interplay between circadian rhythms, aging, and cancer is crucial.
- RCM and circadian rhythm functions offer insights into aging and carcinogenesis.
- Chromatin remodeling presents a novel therapeutic avenue for aging and cancer treatment.

4.1K
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...

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

3.7K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

2.2K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

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.
