    Hybrid protein assembly-histone modification mechanism for PRC2-based epigenetic switching and memory

    Cecilia Lövkvist, Pawel Mikulski ... Martin Howard
    Extra protein memory storage elements with positive feedbacks, in addition to histone modifications, can explain epigenetic switching and memory at the PRC2 target gene FLOWERING LOCUS C (FLC).

    A chemical probe of CARM1 alters epigenetic plasticity against breast cancer cell invasion

    Xiao-Chuan Cai, Tuo Zhang ... Minkui Luo
    A chemical probe was characterized for potency, selectivity, and ability to alter CARM1-dependent epigenetic plasticity against cancer cell invasion.

    Inducible mechanisms of disease tolerance provide an alternative strategy of acquired immunity to malaria

    Wiebke Nahrendorf, Alasdair Ivens, Philip J Spence
    Malaria remodels the spleen to imprint tolerance and reduce pathology in subsequent infections.

    Key epigenetic and signaling factors in the formation and maintenance of the blood-brain barrier

    Jayanarayanan Sadanandan, Sithara Thomas ... Peeyush Kumar T
    Histone deacetylase 2 (HDAC2) and polycomb repressive complex 2 (PRC2) control endothelial gene expression for BBB development and prevented Wnt/β-catenin target genes from being expressed in adult CNS ECs.

    Area-specific development of distinct projection neuron subclasses is regulated by postnatal epigenetic modifications

    Kawssar Harb, Elia Magrinelli ... Christian Alfano
    Lmo4 specifies two neuron subclasses in the mouse neocortex by promoting postnatal co-expression of the transcription factors Ctip2 and Satb2 via chromatin remodelling in a time and area-specific manner.

    Epigenetic drift of H3K27me3 in aging links glycolysis to healthy longevity in Drosophila

    Zaijun Ma, Hui Wang ... Nan Liu
    Epigenetic drift of H3K27me3 is one of the molecular mechanisms that contribute to aging, and stimulation of glycolysis promotes metabolic health and longevity.

    Hemi-methylated DNA regulates DNA methylation inheritance through allosteric activation of H3 ubiquitylation by UHRF1

    Joseph S Harrison, Evan M Cornett ... Scott B Rothbart
    Epigenetic modifications to DNA can regulate E3 ubiquitin ligase activity in human cells.

    Mechanistic target of rapamycin (mTOR) pathway in Sertoli cells regulates age-dependent changes in sperm DNA methylation

    Saira Amir, Olatunbosun Arowolo ... Alexander Suvorov
    For the first time, a molecular mechanism is identified, for experimental acceleration and deceleration (rejuvenation) of sperm epigenetic aging.

    Sequence features of retrotransposons allow for epigenetic variability

    Kevin R Costello, Amy Leung ... Dustin E Schones
    Variably methylated retrotransposons have an underlying sequence that allows them to escape KAP1-mediated silencing and recruit ZF-CxxC proteins.

    Transgressions of compartment boundaries and cell reprogramming during regeneration in Drosophila

    Salvador C Herrera, Ginés Morata
    The reconstruction of damaged structures during regeneration requires cell reprogramming mediated by the up regulation of the JNK pathway and the transient debilitation of the epigenetic control mechanism.
