    Repressive H3K9me2 protects lifespan against the transgenerational burden of COMPASS activity in C. elegans

    Teresa Wei-sy Lee, Heidi Shira David ... David John Katz
    The transgenerational inheritance of lifespan is facilitated by the accumulation of repressive chromatin across generations.

    Heritable epigenetic changes are constrained by the dynamics of regulatory architectures

    Antony M Jose
    A foundation for analyzing epigenetic changes within the context of regulatory architectures that enable heredity.

    Paternal nicotine exposure alters hepatic xenobiotic metabolism in offspring

    Markus P Vallaster, Shweta Kukreja ... Oliver J Rando
    A novel paternal effect based on nicotine exposure reveals that offspring exhibit an adaptive, yet nonspecific, resistance to multiple toxins.

    Exposure to high-sugar diet induces transgenerational changes in sweet sensitivity and feeding behavior via H3K27me3 reprogramming

    Jie Yang, Ruijun Tang ... Liming Wang
    Exposure to high-sugar diet in Drosophila resulted in the suppression of sweet sensitivity and feeding behavior in the offspring via altered epigenetic modifications on the histone, highlighting sustained impact of ancestral experience on the physiology and health of offspring.

    An in vitro approach reveals molecular mechanisms underlying endocrine disruptor-induced epimutagenesis

    Jake D Lehle, Yu-Huey Lin ... John R McCarrey
    The utility of an in vitro cell culture system for studies of molecular mechanisms underlying the initial induction and subsequent propagation of environmentally induced epimutations is demonstrated.

    Maternal obesity may disrupt offspring metabolism by inducing oocyte genome hyper-methylation via increased DNMTs

    Shuo Chao, Jun Lu ... Zhao-Jia Ge
    Maternal obesity mouse model reveal that melatonin deficiency causes the genomic hyper-methylation of oocytes via increasing the expression of DNA methyltransferases.

    Mechanical force of uterine occupation enables large vesicle extrusion from proteostressed maternal neurons

    Guoqiang Wang, Ryan J Guasp ... Monica Driscoll
    Large extracellular vesicle extrusion that eliminates neuronal protein aggregates and organelles is potentiated by uterine filling, linking reproductive status to maternal nervous system health, and demonstrating mechanobiology components in exophergenesis.

    Hyperosmotic stress memory in Arabidopsis is mediated by distinct epigenetically labile sites in the genome and is restricted in the male germline by DNA glycosylase activity

    Anjar Wibowo, Claude Becker ... Jose Gutierrez-Marcos
    Transient adaptation to environmental fluctuations in plants is mediated through discrete epigenetic changes.
