Abstract

Summary: Aging is accompanied by alterations in epigenetic marks that control chromatin states, including histone acetylation and methylation. Enzymes that reversibly affect histone marks associated with active chromatin have recently been found to regulate aging in Caenorhabditis elegans . However, relatively little is known about the importance for aging of histone marks associated with repressed chromatin. Here, we use a targeted RNAi screen in C. elegans to identify four histone demethylases that significantly regulate worm lifespan, UTX‐1, RBR‐2, LSD‐1, and T26A5.5. Interestingly, UTX‐1 belongs to a conserved family of histone demethylases specific for lysine 27 of histone H3 (H3K27me3), a mark associated with repressed chromatin. Both utx‐1 knockdown and heterozygous mutation of utx‐1 extend lifespan and increase the global levels of the H3K27me3 mark in worms. The H3K27me3 mark significantly drops in somatic cells during the normal aging process. UTX‐1 regulates lifespan independently of the presence of the germline, but in a manner that depends on the insulin‐FoxO signaling pathway. These findings identify the H3K27me3 histone demethylase UTX‐1 as a novel regulator of worm lifespan in somatic cells.

  • Knockdown of H3K27me3 demethylase UTX-1 increases lifespan in C. elegans, suggesting H3K27me3 levels are beneficial for longevity.

    “Knockdown of the H3K27me3 demethylase UTX-1 increases lifespan in C. elegans (Jin et al., 2011; Maures et al., 2011; Ni et al., 2012), suggesting that H3K27me3 levels are beneficial for longevity.”

  • Age-associated changes in global H3K27me3 levels are context dependent.

    “Interestingly, age-associated changes in global H3K27me3 levels are also context dependent.”

  • Global H3K27me3 increases with age in killifish brain and mouse quiescent satellite cells but decreases during C. elegans aging and in human progeria models.

    “Global H3K27me3 increases with age in the killifish brain and mouse quiescent satellite cells (Baumgart et al., 2014; Liu et al., 2013) but decreases with age during C. elegans aging and in human progeria models (Maures et al., 2011; Ni et al., 2012; Shumaker et al., 2006; Zhang et al., 2015b).”

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.
