Summary
Epigenetic alterations, including DNA methylation and histone modifications, are key drivers in prostate cancer development and progression. Targeting these epigenomic changes offers potential novel therapeutic strategies for this widespread cancer.
Area of Science:
- Oncology
- Epigenetics
Background:
- Prostate cancer is a leading cause of cancer death in men globally.
- Epigenetic alterations, including DNA methylation and histone modifications, play a significant role in prostate cancer development alongside genomic changes.
Purpose of the Study:
- To provide a comprehensive overview of epigenetic alterations in prostate cancer.
- To focus on the roles of DNA methylation and histone modifications in prostate cancer development and progression.
Main Methods:
- Review of existing literature on epigenetic alterations in prostate cancer.
- Analysis of the impact of DNA methylation (hyper- and hypomethylation) and histone modifications (acetylation, methylation, phosphorylation, ubiquitination) on gene expression and cancer development.
Main Results:
- Aberrant DNA hypermethylation inactivates tumor suppressor genes involved in DNA repair, cell cycle, apoptosis, and cell adhesion.
- Aberrant DNA hypomethylation can lead to oncogene activation.
- Histone acetylation deregulation contributes to aberrant super-enhancer formation and gene activation.
- Histone methylation (e.g., H3K27 trimethylation via EZH2) and other modifications are implicated in prostate cancer.
Conclusions:
- Epigenetic aberrations are crucial in prostate cancer pathogenesis.
- Targeting these epigenomic alterations presents promising avenues for novel therapeutic strategies.

01:37Epigenetic Regulation
3.5K
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.

02:04Covalently Linked Protein Regulators
8.2K
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.

02:32Histone Modification
15.3K
The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.

The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.
