Summary
Inherited DNA methylation patterns can influence cancer risk. This study identified 41 heritable methylation marks linked to prostate cancer risk, with 9 near VTRNA2-1 associated with aggressive forms.
Area of Science:
- Genetics
- Epigenetics
- Cancer Research
Background:
- Inherited DNA methylation marks are implicated in familial cancer risk.
- Understanding these heritable marks is crucial for assessing cancer susceptibility.
Purpose of the Study:
- To conduct a genome-wide search for heritable DNA methylation marks associated with prostate cancer risk.
- To identify specific methylation patterns that may explain familial prostate cancer aggregation.
Main Methods:
- Measured peripheral blood DNA methylation in 133 members from 25 multi-case prostate cancer families using the EPIC array.
- Identified methylation marks with Mendelian inheritance patterns.
- Tested the 1,000 most heritable marks for association with prostate cancer risk.
Main Results:
- Identified 41 heritable DNA methylation marks significantly associated with prostate cancer risk after multiple testing correction.
- Nine of these marks, located near the VTRNA2-1 metastable epiallele, showed nominal association with aggressive prostate cancer risk in a separate prospective cohort study.
Conclusions:
- Heritable DNA methylation marks are associated with prostate cancer risk.
- Specific methylation marks, particularly those near VTRNA2-1, may serve as biomarkers for aggressive prostate cancer.

02:30Genomic Imprinting and Inheritance
34.9K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.

6.4K
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...

02:59Cancer Prevention
6.3K
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.

02:23Abnormal Proliferation
4.6K
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...
