Summary
Epigenetic alterations are crucial in human prostate cancer development and progression. Specific epigenetic markers, like histone modifications and DNA methylation, can serve as diagnostic and prognostic biomarkers for this disease.
Area of Science:
- Oncology
- Epigenetics
- Molecular Biology
Background:
- Epigenetic alterations are increasingly recognized as key drivers in human prostate cancer.
- Understanding these changes offers insights into cancer origins and potential biomarkers.
Purpose of the Study:
- To review the role of epigenetic modifications in prostate cancer development.
- To highlight epigenetic alterations as potential diagnostic and prognostic biomarkers.
- To explore epigenetic machinery as therapeutic targets.
Main Methods:
- Analysis of epigenetic patterns, including DNA methylation and histone modifications.
- Examination of protein complex alterations (e.g., polycomb group proteins).
- Review of small RNA roles in epigenetic regulation.
Main Results:
- Methylation patterns suggest a stem cell origin for prostate cancer.
- Specific histone marks (e.g., H3K9ac, H3K18ac, H4K12ac, H4R3me2, H3K4me2) differentiate low-grade prostate cancer prognosis.
- Elevated EZH2, BMI1, and RING1 levels correlate with poor clinical outcomes.
- GSTpi methylation is a recognized marker for prostate cancer.
Conclusions:
- Epigenetic changes are fundamental to prostate cancer.
- Identified epigenetic markers hold promise for diagnostics and prognostics.
- Epigenetic machinery components are viable therapeutic targets.
- Small RNAs present novel therapeutic and chemoprevention strategies.

01:37Epigenetic Regulation
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.

02:59Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

01:33Cancer-Critical Genes I: Proto-oncogenes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

03:17Inheritance of Chromatin Structures
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying DNA...
