  2. Cellular stress response - Wikipedia

    en.wikipedia.org/wiki/Cellular_stress_response

    Cellular stress responses are primarily mediated through what are classified as stress proteins.Stress proteins often are further subdivided into two general categories: those that only are activated by stress, or those that are involved both in stress responses and in normal cellular functioning.

  3. Integrated stress response - Wikipedia

    en.wikipedia.org/wiki/Integrated_stress_response

    The integrated stress response can be triggered within a cell due to either extrinsic or intrinsic conditions. Extrinsic factors include hypoxia, amino acid deprivation, glucose deprivation, viral infection and presence of oxidants. The main intrinsic factor is endoplasmic reticulum stress due to the accumulation of unfolded proteins.

  4. Stress (biology) - Wikipedia

    en.wikipedia.org/wiki/Stress_(biology)

    For instance, extreme stress (e.g. trauma) is a requisite factor to produce stress-related disorders such as post-traumatic stress disorder. [6] A 2024 review by Cochrane reported that the global estimated lifetime prevalence of post-traumatic stress disorder (PTSD) in adults is approximately 3.9%.

  5. Transcriptional regulation - Wikipedia

    en.wikipedia.org/wiki/Transcriptional_regulation

    Expression of EGR1 transcription factor proteins, in various types of cells, can be stimulated by growth factors, neurotransmitters, hormones, stress and injury. [24] In the brain, when neurons are activated, EGR1 proteins are up-regulated and they bind to (recruit) the pre-existing TET1 enzymes which are highly expressed in neurons.

  6. Chronic stress - Wikipedia

    en.wikipedia.org/wiki/Chronic_stress

    Prolonged stress can disturb the immune, digestive, cardiovascular, sleep, and reproductive systems. [17] For example, it was found that: Chronic stress reduces resistance of infection and inflammation, and might even cause the immune system to attack itself. [27] Stress responses can cause atrophy of muscles and increases in blood pressure. [28]

  7. Stressor - Wikipedia

    en.wikipedia.org/wiki/Stressor

    A stressor is a chemical or biological agent, environmental condition, external stimulus or an event seen as causing stress to an organism. [1] Psychologically speaking, a stressor can be events or environments that individuals might consider demanding, challenging, and/or threatening individual safety.

  8. Epigenetics of anxiety and stress–related disorders - Wikipedia

    Paternal stress is an important factor in the determination of inheritance of genes as well as maternal stress inheritance. Factors such as environment and experiences can alter the epigenetic of paternal genes as well as in sperm. Epigenetic changes to the DNA in sperm ("epigenetic tags") prior to conception can be passed to offspring.
