  • Chicks from stressed females elicit overprotective behaviour in adoptive mother quail. [Journal Article]
    Behav Processes. 2020 Jul 06 [Online ahead of print]Aigueperse N, Houdelier C, … Lumineau S
  • Beyond the genetic links between mother and young, prenatal effects experienced by offspring can modulate their mother's behaviour and stress. Here we investigated the consequences of stress-induced prenatal maternal effects on quail chicks' behaviour and maternal behaviour. We evaluated how adoptive quail mothers (unstressed) raised chicks of females that had either been stressed (PS) or were no…

  • Programming and reprogramming from conception till death [Journal Article]
    Orv Hetil. 2020 06; 161(25):1028-1034.Csaba G
  • During conception (fusion of maternal and paternal germ cells) a new entity is formed, which has individual structure and functions. From its gene-pool (genome) epigenetic regulation selects those genes which are durably or acutely working, supplying a theoretically lifelong program. However, this program could be changed spontaneously or artificially, and there are life periods when the spontane…

  • Mobile genetic elements threaten genome integrity in all organisms. RDE-3 (also known as MUT-2) is a ribonucleotidyltransferase that is required for transposon silencing and RNA interference in Caenorhabditis elegans1-4. When tethered to RNAs in heterologous expression systems, RDE-3 can add long stretches of alternating non-templated uridine (U) and guanosine (G) ribonucleotides to the 3' termin…
  • Why does COVID-19 disproportionately affect older people? [Journal Article]
    Aging (Albany NY). 2020 05 29; 12(10):9959-9981.Mueller AL, McNamara MS, Sinclair DA
  • The severity and outcome of coronavirus disease 2019 (COVID-19) largely depends on a patient's age. Adults over 65 years of age represent 80% of hospitalizations and have a 23-fold greater risk of death than those under 65. In the clinic, COVID-19 patients most commonly present with fever, cough and dyspnea, and from there the disease can progress to acute respiratory distress syndrome, lung cons…
  • Nonequilibrium Strategy for Fast Target Search on the Genome. [Journal Article]
    Phys Rev Lett. 2020 May 15; 124(19):198101.Cagnetta F, Michieletto D, Marenduzzo D
  • Vital biological processes such as genome repair require fast and efficient binding of selected proteins to specific target sites on DNA. Here we propose an active target search mechanism based on "chromophoresis," the dynamics of DNA-binding proteins up or down gradients in the density of epigenetic marks, or colors (biochemical tags on the genome). We focus on a set of proteins that deposit mar…

  • Epigenetic Methods and Twin Studies. [Review]
    Adv Exp Med Biol. 2020; 1253:95-104.Ceribelli A, Selmi C
  • Genomic predisposition fails to fully explain the onset of complex diseases, which is well illustrated by the largely incomplete concordance among monozygotic twins. Epigenetic mechanisms, including DNA methylation, chromatin remodeling, and non-coding RNA, are the link between environmental stimuli and disease onset on a permissive genetic background in autoimmune and chronic inflammatory diseas…
  • The Development of Epigenetics in the Study of Disease Pathogenesis. [Review]
    Adv Exp Med Biol. 2020; 1253:57-94.Jeffries MA
  • The study of epigenetics has its roots in the study of organism change over time and response to environmental change, although over the past several decades the definition has been formalized to include heritable alterations in gene expression that are not a result of alterations in underlying DNA sequence. In this chapter, we discuss first the history and milestones in the 100+ years of epigene…
  • Epigenetics in Health and Disease. [Review]
    Adv Exp Med Biol. 2020; 1253:3-55.Zhang L, Lu Q, Chang C
  • Epigenetic mechanisms, which include DNA methylation, histone modification, and microRNA (miRNA), can produce heritable phenotypic changes without a change in DNA sequence. Disruption of gene expression patterns which are governed by epigenetics can result in autoimmune diseases, cancers, and various other maladies. Mechanisms of epigenetics include DNA methylation (and demethylation), histone mo…
  • On the problem of biological form. [Journal Article]
    Theory Biosci. 2020 May 16 [Online ahead of print]Linde-Medina M
  • Embryonic development, which inspired the first theories of biological form, was eventually excluded from the conceptual framework of the Modern Synthesis as irrelevant. A major question during the last decades has centred on understanding whether new advances in developmental biology are compatible with the standard view or whether they compel a new theory. Here, I argue that the answer to this …
