Abstract:
Epigenetics is considered as the science of hereditary phenotype which does not encompass amendment in the DNA. This occurs through chemical processes that modify the phenotype, without altering the genotype. A large number of studies showed that metabolic diseases are highly associated with epigenetic alterations suggesting that epigenetic factors may play a central role in cancer. Recent advancements in the rapidly evolving field of cancer epigenetics have shown extensive reprogramming of every component of the epigenetic machinery in cancer including DNA methylation, histone modifications,

Abstract:
Cancer is a disease with extraordinary clinical significance, with much of medical research being devoted to it. Innumerable factors are relevant in fully understanding cancer but the epigenetic aspect stands out. Epigenetics is the study of changes, often germ-line, to the genome affecting the gene expression by silencing certain genes and modifying the gene expression. The three primary mechanisms for epigenetic changes are DNA methylation, histone modification and non-coding RNA (ncRNA) associated gene silencing.

Abstract Cancer development takes 10 to 50 years, and epigenetics plays an important role. Recent evidence suggests that ~80% of human cancers are linked to environmental factors impinging upon genetics/epigenetics.

Many dietary phytochemicals possess powerful antioxidant and anti-inflammatory properties that are hallmarks of cancer prevention.

Abstract:
Epigenetics is the study of heritable changes in gene expression that occur without changes to the underlying DNA sequence. Epigenetic modifications can include DNA methylation, histone modifications, and non-coding RNAs, among others. These modifications can influence the expression of genes by altering the way DNA is packaged and accessed by transcriptional machinery, thereby affecting cellular function and behavior. Epigenetic modifications can be influenced by a variety of factors, including environmental exposures, lifestyle factors, and aging, whilst abnormal epigenetic modifications hav

Abstract:
Technological advancements in cell-free DNA (cfDNA) liquid biopsy have triggered exponential growth in numerous clinical applications. While cfDNA-based liquid biopsy has made significant strides in personalizing cancer treatment, the exploration and translation of epigenetics in liquid biopsy to clinical practice is still nascent. This comprehensive review seeks to provide a broad yet in-depth narrative of the present status of epigenetics in cfDNA liquid biopsy and its associated challenges. It highlights the potential of epigenetics in cfDNA liquid biopsy technologies with the hopes of enha

Abstract:
In recent years, significant strides in both conceptual understanding and technological capabilities have bolstered our comprehension of the factors underpinning cancer initiation and progression. While substantial insights have unraveled the molecular mechanisms driving carcinogenesis, there has been an overshadowing of the critical contribution made by epigenetic pathways, which works in concert with genetics. Mounting evidence demonstrates cancer as a complex interplay between genetics and epigenetics. Notably, epigenetic elements play a pivotal role in governing alternative pre-mRNA splici

Abstract:
Age is the greatest risk factor for breast cancer, but the reasons underlying this association are unclear. While there is undeniably a genetic component to all cancers, the accumulation of mutations with age is insufficient to explain the age-dependent increase in breast cancer incidence. In this viewpoint, we propose a multilevel framework to better understand the respective roles played by somatic mutation, microenvironment, and epigenetics making women more susceptible to breast cancer with age. The process of aging is associated with gradual breast tissue changes that not only corrupt the

Abstract: Epigenetics, the study of heritable changes in gene expression without alterations to the DNA sequence, is crucial for the complex interplay of genetic and environmental factors influencing human health. This overview traces the historical evolution of epigenetics, from early conceptualizations by Valentin Haecker and Conrad Waddington to modern insights such as epigenetic editing. Key mechanisms such as DNA methylation, histone modifications, and noncoding RNAs are explored, highlighting their roles in various diseases including cancer, cardiovascular conditions, neurodegenerative d

Abstract:
The critical role of dysregulated epigenetic pathways in cancer genesis, development, and therapy has typically been established as a result of scientific and technical innovations in next generation sequencing. RNA interference, histone modification, DNA methylation and chromatin remodelling are epigenetic processes that control gene expression without causing mutations in the DNA. Although epigenetic abnormalities are thought to be a symptom of cell tumorigenesis and malignant events that impact tumor growth and drug resistance, physicians be

Abstract:
Epigenetics regulates gene expression, cell type development during differentiation, and the cell response to environmental stimuli. To survive, bacteria need to evade the host immune response. Bacteria, including Helicobacter pylori (Hp), reach this target epigenetically, altering the chromatin of the host cells, in addition to several more approaches, such as DNA mutation and recombination. This review shows that Hp prevalently silences the genes of the human gastric mucosa by DNA methylation. Epigenetics includes different mechanisms. However, DNA methylation persists after DNA replication
