    Determining the effects of paternal obesity on sperm chromatin at histone H3 lysine 4 tri-methylation in relation to the placental transcriptome and cellular composition

    Anne-Sophie Pepin, Patrycja A Jazwiec ... Sarah Kimmins
    Epigenomic and transcriptomic analysis reveals that paternal obesity influences sperm histone H3 lysine 4 tri-methylation enrichment and placenta gene expression, which in turn negatively impact its development and function in a manner that may contribute to metabolic disease in offspring.

    Discarded sequencing reads uncover natural variation in pest resistance in Thlaspi arvense

    Dario Galanti, Jun Hee Jung ... Oliver Bossdorf
    Aphid and mildew read counts leftover from the sequencing of greenhouse plants correlated with the environment of origin of the plants, and allowed the mapping of pathogen resistance genes.

    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.

    A scenario for an evolutionary selection of ageing

    Tristan Roget, Claire Macmurray ... Michael Rera
    Ageing is broadly accepted as a by-product of evolution, as thus, models allowing to conceive ageing as an adaptive force of evolution could show significant importance at a time of biogerontology mostly aiming at curing ageing.

    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.

    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.

    Differential susceptibility of male and female germ cells to glucocorticoid-mediated signaling

    Steven A Cincotta, Nainoa Richardson ... Diana J Laird
    Although developing oocytes and sperm of mice both harbor the glucocorticoid receptor, fetal oocytes are resistant to differing levels of gluocorcorticoid stress hormones, while spermatogonia alter RNA splicing.

    Metabolic memory of Δ9-tetrahydrocannabinol exposure in pluripotent stem cells and primordial germ cells-like cells

    Roxane Verdikt, Abigail A Armstrong ... Patrick Allard
    Exposure of embryonic stem cells to physiological concentrations of Δ9-THC remodels cellular metabolism across differentiation.
