Summary
Epigenetic alterations, including DNA methylation and histone modifications, are key drivers in hepatocellular carcinoma (HCC) development. Targeting these reversible changes offers new therapeutic strategies for liver cancer.
Area of Science:
- Oncology
- Molecular Biology
- Epigenetics
Background:
- Hepatocellular carcinoma (HCC) presents a significant clinical challenge with a poor prognosis.
- The underlying molecular pathogenesis of HCC remains incompletely understood.
- Recent molecular studies have identified numerous genetic and epigenetic alterations in HCC.
Purpose of the Study:
- To review the epigenetic changes involved in hepatocellular carcinoma pathogenesis.
- To explore the potential of epigenetic modifications as therapeutic targets in HCC.
- To discuss the implications of epigenetic alterations for predicting treatment response in HCC.
Main Methods:
- Review of recent scientific literature on epigenetic modifications in HCC.
- Analysis of genetic and epigenetic alterations, including DNA methylation and histone modifications.
- Investigation of the role of non-coding RNAs and cancer stem cells in HCC development.
Main Results:
- HCC pathogenesis involves altered DNA methylation patterns and enzyme dysfunction.
- Histone modifications significantly impact gene expression in HCC cells.
- Dysregulated non-coding RNAs (microRNAs, long non-coding RNAs) and liver cancer stem cells contribute to HCC.
Conclusions:
- Epigenetic changes in HCC are crucial for its development and progression.
- The reversible nature of epigenetic modifications presents opportunities for novel therapeutic interventions.
- Understanding these epigenetic alterations can guide personalized treatment strategies and improve patient outcomes.

01:37Epigenetic Regulation
3.2K
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.

01:58Cell Specific Gene Expression
14.3K
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

03:17Inheritance of Chromatin Structures
6.8K
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...

02:30Genomic Imprinting and Inheritance
35.7K
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.

02:59Cancer Prevention
6.8K
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.

01:32Chromatin Modification in iPS Cells
2.0K
Chromatin modification alters gene expression; therefore, scientists can add histone-modifying enzymes, histone variants, and chromatin remodeling complexes to somatic cells to aid reprogramming into pluripotent stem (iPS) cells.
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...
