  2. Cancer epigenetics - Wikipedia

    en.wikipedia.org/wiki/Cancer_epigenetics

    Cancer-related metabolic changes lead to locus-specific recoding of epigenetic marks. Cancer epigenetics can be precisely reprogramed by cellular metabolism through 1) dose-responsive modulation of cancer epigenetics by metabolites; 2) sequence-specific recruitment of metabolic enzymes; and 3) targeting of epigenetic enzymes by nutritional ...

  3. Epigenetics and melanoma - Wikipedia

    en.wikipedia.org/wiki/Epigenetics_and_melanoma

    Epigenetics is the term used to refer to stable changes in DNA that affect gene expression but do not involve changes in the underlying nucleotide sequence of the organism (Patino et al. 2008). The mechanisms by which epigenetics occur involve hypo- and hypermethylation of DNA, histone modifications by acetylation , methylation , and ...

  4. Somatic evolution in cancer - Wikipedia

    en.wikipedia.org/wiki/Somatic_evolution_in_cancer

    In addition to well studied epigenetic promoter methylation, more recently there have been substantial findings of epigenetic alterations in cancer due to changes in histone and chromatin architecture and alterations in the expression of microRNAs (microRNAs either cause degradation of messenger RNAs or block their translation) [54] For ...

  5. Carcinogenesis - Wikipedia

    en.wikipedia.org/wiki/Carcinogenesis

    The central role of DNA damage and epigenetic defects in DNA repair genes in carcinogenesis. DNA damage is considered to be the primary cause of cancer. [17] More than 60,000 new naturally-occurring instances of DNA damage arise, on average, per human cell, per day, due to endogenous cellular processes (see article DNA damage (naturally occurring)).

  6. Epigenetics - Wikipedia

    en.wikipedia.org/wiki/Epigenetics

    Epigenetic mechanisms. In biology, epigenetics is the study of heritable traits, or a stable change of cell function, that happen without changes to the DNA sequence. [1] The Greek prefix epi-(ἐπι-"over, outside of, around") in epigenetics implies features that are "on top of" or "in addition to" the traditional (DNA sequence based) genetic mechanism of inheritance.

    Recently, the team published their research in Frontiers in Aging, showing that CheekAge can accurately predict mortality risk, even when epigenetic data from other tissues is used.

  8. Epigenetic priming - Wikipedia

    en.wikipedia.org/wiki/Epigenetic_Priming

    Epigenetic priming refers to a latent epigenetic state triggered by stimuli, such as a drug or environmental changes. The epigenetically primed state is characterized by chromatin loosening, which is the change of chromatin state from heterochromatin (tightly bound and inaccessible) to euchromatin (loosely bound and fully accessible), which leads to an increased transcription of certain genes ...

  9. Cancer research - Wikipedia

    en.wikipedia.org/wiki/Cancer_research

    Cancer epigenetics is the study of epigenetic modifications to the DNA of cancer cells that do not involve a change in the nucleotide sequence, but instead involve a change in the way the genetic code is expressed.
