Summary
Colorectal cancer, a major health threat, progresses through genetic and epigenetic changes. Understanding these epigenetic alterations aids in early diagnosis, prognosis, and treatment strategies for colorectal cancer.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Colorectal cancer (CRC) is a leading cause of cancer-related mortality worldwide.
- Its development involves complex genetic and epigenetic alterations.
- Epigenetic modifications play a crucial role in CRC pathogenesis.
Purpose of the Study:
- To explore the significance of epigenetic changes in colorectal cancer.
- To highlight the role of DNA methylation, histone modification, and non-coding RNAs in CRC.
- To underscore the potential of epigenetic markers for clinical applications in CRC.
Main Methods:
- Review of current literature on epigenetic alterations in colorectal cancer.
- Analysis of the roles of DNA methylation, histone modifications, and non-coding RNAs (microRNAs, lncRNAs).
- Examination of the clinical implications of these epigenetic changes.
Main Results:
- Epigenetic changes, including DNA methylation, histone modification, and non-coding RNAs, are integral to colorectal cancer progression.
- These epigenetic mechanisms influence key cellular processes relevant to cancer development.
- Specific epigenetic markers show promise for early detection and outcome prediction.
Conclusions:
- Epigenetic alterations are critical drivers in colorectal cancer.
- Epigenetic markers offer valuable tools for early diagnosis, prognosis, and chemosensitivity assessment in CRC.
- Targeting epigenetic pathways presents a novel therapeutic avenue for colorectal cancer treatment.

Epigenetic Regulation
33.5K
Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Epigenetic Regulation
3.7K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

mTOR Signaling and Cancer Progression
4.6K
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.

Tumor Progression
7.2K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Cancer
53.6K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

What is Cancer?
14.0K
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
