Epigenetic inheritance of acquired traits through sperm RNAs and sperm RNA modifications

Abstract

Once deemed heretical, emerging evidence now supports the notion that the inheritance of acquired characteristics can occur through ancestral exposures or experiences and that certain paternally acquired traits can be 'memorized' in the sperm as epigenetic information. The search for epigenetic factors in mammalian sperm that transmit acquired phenotypes has recently focused on RNAs and, more recently, RNA modifications. Here, we review insights that have been gained from studying sperm RNAs and RNA modifications, and their roles in influencing offspring phenotypes. We discuss the possible mechanisms by which sperm become acquisitive following environmental-somatic-germline interactions, and how they transmit paternally acquired phenotypes by shaping early embryonic development.

  • Long-lived RNA molecules appear to be less affected by these barriers and therefore more likely to carry epigenetic information across generations.

    “Long-lived RNA molecules appear to be less affected by these barriers and therefore more likely to carry epigenetic information across generations4, although the mechanisms are largely unsolved.”

    From A critical view on transgenerational epigenetic inheritance in humans (2018) · cites this paper as [4]

    The Abstract (page unavailable) says non-coding RNAs can escape epigenetic reprogramming and that sperm RNAs can transfer acquired traits. The Sperm RNA modifications section (page unavailable) suggests that modifications increase tsRNA stability and may preserve its function after fertilization. It does not establish that long-lived RNA molecules generally are less affected by the barriers or more likely than shorter-lived RNAs to carry information across generations. (LLM, conf=0.85)

  • Numerous reports on transgenerational responses to environmental or metabolic factors in mice and rats have been published in the past 10 years.

    “In the past 10 years, numerous reports on transgenerational responses to environmental or metabolic factors in mice and rats have been published (for a comprehensive review, see refs. 4–7).”
  • The factors studied include endocrine disruptors, high fat diet, obesity, diabetes, undernourishment as well as trauma.

    “The factors include endocrine disruptors, high fat diet, obesity, diabetes, undernourishment as well as trauma.”
  • DNA methylation was an early proposed carrier of epigenetic information, and later work showed chromatin proteins and noncoding RNAs also matter.

    “DNA methylation was proposed early on as a carrier of epigenetic information with subsequent work revealing that chromatin proteins and noncoding RNAs are also important for this process [10][11][12][13][14] .”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
