    Mouse brain transcriptome responses to inhaled nanoparticulate matter differed by sex and APOE in Nrf2-Nfkb interactions

    Amin Haghani et al.
    Transcriptome analysis of mouse brain revealed that the APOE4 allele and sex can alter air pollution neurotoxicity in adults.

    Gene regulation gravitates toward either addition or multiplication when combining the effects of two signals

    Eric M Sanford et al.
    When two signals increase transcription of the same gene, their combined effect tends to reflect either the sum of the individual increases or the product of the individual fold-changes.

    Regulation of shoot meristem shape by photoperiodic signaling and phytohormones during floral induction of Arabidopsis

    Atsuko Kinoshita et al.
    The shoot meristem becomes domed in shape during floral transition and this is controlled by flowering pathways and the phytohormone gibberellin causing increases in cell size and number.

    Matrix metalloproteinase 1 modulates invasive behavior of tracheal branches during entry into Drosophila flight muscles

    Julia Sauerwald et al.
    Tracheal-derived matrix metalloproteinase 1 activity sustains tracheal branch invasion into myotubes by modulating ECM properties and dynamic behavior of sprouting tip cells.

    The splicing regulator PTBP2 controls a program of embryonic splicing required for neuronal maturation

    Qin Li et al.
    PTBP2 ensures that adult protein variants are expressed only in mature neurons through regulation of alternative splicing during early neuronal development.

    Stella modulates transcriptional and endogenous retrovirus programs during maternal-to-zygotic transition

    Yun Huang et al.
    Soon after fertilisation, a critical portion of the embryonic genome is switched on through the actions of maternally inherited Stella, in part through controlling the activation of transposable elements.

    A multicellular rosette-mediated collective dendrite extension

    Li Fan et al.
    Migrating skin carries the amphid rosette vertex anteriorly to extrude and position dendrites.
