Non-CpG methylation-a key epigenetic modification in cancer
Briefings in Functional Genomics
|July 28, 2021
Summary
Non-CpG methylation, an epigenetic modification, plays a role in gene regulation. This review explores its mechanisms in development and cancer, highlighting its potential impact on cancer progression.
Area of Science:
- Epigenetics
- Molecular Biology
- Genomics
Background:
- Non-CpG methylation, the methylation of cytosine residues not followed by guanine, is a significant epigenetic modification.
- It plays a crucial role in gene regulation, analogous to CpG methylation.
- Previous technological limitations hindered understanding of its locus-specific functions.
Purpose of the Study:
- To review the mechanisms of non-CpG methylation in embryonic and developed tissues.
- To elucidate the role of non-CpG methylation in cancer development and progression.
- To discuss factors influencing non-CpG methylation levels and their functional significance in cancer.
Main Methods:
- Review of current literature on non-CpG methylation.
- Analysis of high-throughput sequencing and enrichment methods.
- Discussion of epigenetic mechanisms and their role in oncogenesis.
Main Results:
- Advances in high-throughput analyses enable genome-wide elucidation of non-CpG methylation distributions.
- The functional basis of non-CpG methylation in gene expression is established.
- The specific role of non-CpG methylation in cancer development requires further investigation.
Conclusions:
- Non-CpG methylation is a key epigenetic regulator with potential implications in cancer.
- Understanding its maintenance, alteration, and regulatory factors is crucial for cancer research.
- Further studies are needed to fully ascertain the role of non-CpG methylation in cancer progression.

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

01:37Epigenetic Regulation
3.3K
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.

02:23Abnormal Proliferation
4.8K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

01:06Induced Pluripotent Stem Cells
4.7K
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

02:04Covalently Linked Protein Regulators
8.1K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.

02:38Mitogens and the Cell Cycle
7.2K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
