- Remodeling the epigenome and (epi)cytoskeleton: a new paradigm for co-regulation by methylation
Summary: A shared chromatocytoskeletal machinery uses methylation to remodel chromatin and the cytoskeleton; we discuss how this might regulate and integrate cellular functions, and suggest the term ‘epiregulation’ to describe this co-regulation.
- Changes in the expression of genes involved in DNA methylation and histone modification in response to daily food availability times in zebra finches: epigenetic implications
Summary: An enforced daily feeding schedule in the long term could serve as a conditioning environment that shapes overall hypothalamic regulation, liver and gonadal functions in diurnal vertebrates at the genetic levels.
- Parental stressor exposure simultaneously conveys both adaptive and maladaptive larval phenotypes through epigenetic inheritance in the zebrafish (Danio rerio)
Editors' Choice: Exposure to environmental stressors may be detrimental for a population; however, it may prompt epigenetically inherited adaptive phenotypes in the offspring, acting as a bridge for survival when persistent stressors occur.
- Histone deacetylase activity is required for Botrylloides leachii whole-body regeneration
Summary: Histone deacetylases are key epigenetic modifiers in Botrylloides leachii, a tunicate capable of whole-body regeneration. HDAC activity is required for regeneration and correct gene expression in this novel model system.
- Changes of gene expression but not cytosine methylation are associated with male parental care reflecting behavioural state, social context and individual flexibility
Summary: Behavioural state has more influence on gene expression than social context or individual flexibility during a transition to parental care, whereas cytosine methylation is not associated with differential gene expression.
- Genetic accommodation and the role of ancestral plasticity in the evolution of insect eusociality
Summary: Social insects are excellent models for studying phenotypic plasticity. We review issues associated with understanding the genetics of plasticity-first evolution and outline an empirical approach to help advance this field.
- Learning to starve: impacts of food limitation beyond the stress period
Summary: Animals previously exposed to starvation exhibit a wide range of physiological and molecular changes, some of which persist long afterwards and may offer them and subsequent generations protection from future starvation events.
- Long-term programming effect of embryonic hypoxia exposure and high-carbohydrate diet at first feeding on glucose metabolism in juvenile rainbow trout
Summary: Embryonic hypoxia and dietary stimuli can affect growth performance and the mRNA levels of glucose-metabolism-related genes in juvenile rainbow trout.
- DNA methylation profiles in red blood cells of adult hens correlate with their rearing conditions
Summary: Differential DNA methylation occurs in red blood cells of adult hens reared under different conditions, i.e. in cages or open aviaries.
- Preconditioning in the reef-building coral Pocillopora damicornis and the potential for trans-generational acclimatization in coral larvae under future climate change conditions
Highlighted Article: Preconditioning and trans-generational acclimatization may provide a buffer for reef-building corals against the stress of rapidly changing climate.
