  2. Epigenetic therapy - Wikipedia

    en.wikipedia.org/wiki/Epigenetic_therapy

    Epigenetics is the study of changes in gene expression that do not arise from alterations in the DNA sequence, resulting in the heritable silencing of genes without changing the coding sequence. Epigenetic therapy involves using drugs or other techniques to influence these epigenetic mechanisms in addressing specific medical conditions.

  3. Pharmacoepigenetics - Wikipedia

    en.wikipedia.org/wiki/Pharmacoepigenetics

    Individual differences in drug metabolism and response can be partially explained by epigenetic changes. [7] [8] Epigenetic changes in genes that encode drug targets, enzymes, or transport proteins that affect the body's ability to absorb, metabolize, distribute and excrete substances that are foreign to the body (Xenobiotics) can result in changes in one's toxicity levels and drug response.

  4. 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. [2]

  5. Regulation of gene expression - Wikipedia

    en.wikipedia.org/wiki/Regulation_of_gene_expression

    Drugs of abuse cause three types of epigenetic alteration in the brain. These are (1) histone acetylations and histone methylations, (2) DNA methylation at CpG sites, and (3) epigenetic downregulation or upregulation of microRNAs. [11] [12] (See Epigenetics of cocaine addiction for some details.)

    Epigenetics of anxiety and stress–related disorders is the field studying the relationship between epigenetic modifications of genes and anxiety and stress-related disorders, including mental health disorders such as generalized anxiety disorder (GAD), post-traumatic stress disorder, obsessive-compulsive disorder (OCD), and more.

    The researchers suggest that their epigenetic clock, which was trained using cheek cell data, can predict mortality even when the methylome is measured in blood cells, indicating that common ...

  8. Behavioral epigenetics - Wikipedia

    en.wikipedia.org/wiki/Behavioral_epigenetics

    Behavioral epigenetics is the field of study examining the role of epigenetics in shaping animal and human behavior. [1] It seeks to explain how nurture shapes nature, [2] where nature refers to biological heredity [3] and nurture refers to virtually everything that occurs during the life-span (e.g., social-experience, diet and nutrition, and exposure to toxins). [4]
