Summary
Disruptions in the body's internal clock (circadian rhythm) are linked to breast cancer. This study explores the molecular links between circadian clock mechanisms and tumor development.
Area of Science:
- Chronobiology
- Oncology
- Molecular Biology
Background:
- The circadian clock regulates essential physiological and behavioral systems.
- Dysfunctional circadian clocks are associated with various pathologies.
- Epidemiological data suggest a correlation between circadian rhythm disruption and breast cancer incidence.
Purpose of the Study:
- To investigate the molecular pathways connecting the circadian machinery to breast cancer development.
- To elucidate the mechanisms underlying the link between circadian disruption and tumorigenesis.
Main Methods:
- Speculative analysis of molecular pathways.
- Review of existing epidemiological and molecular data.
- Hypothesizing potential links between clock genes and breast cancer.
Main Results:
- Identification of potential molecular signaling cascades.
- Hypothesized roles for specific clock-controlled genes in cancer progression.
- Proposed mechanisms for how circadian disruption may promote breast cancer.
Conclusions:
- Circadian clock dysfunction may contribute to breast cancer initiation and progression.
- Further research is needed to validate the proposed molecular pathways.
- Understanding these links could offer novel therapeutic strategies for breast cancer.

02:19Circadian Rhythms and Gene Regulation
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 years,...

02:45Biological Clocks and Seasonal Responses
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.
02:39Positive Regulator Molecules
Mitotic cell division results in daughter cells that exactly resemble the parent cell. However, errors in the DNA replication or distribution of genetic material may lead to genetic mutations that may be passed down to every new cell formed from the resulting abnormal cell. Propagation of such mutant cells is restricted through checkpoint mechanisms present at different stages of the cell cycle. These checkpoints involve regulator molecules that either promote or demote cell cycle events.
03:03mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
