    The Hox transcription factor Ubx stabilizes lineage commitment by suppressing cellular plasticity in Drosophila

    Katrin Domsch et al.
    The Hox transcription factor Ultrabithorax (Ubx) represses alternative gene programs during lineage development by lineage-specific Polycomb protein complex retention at Ubx-targeted chromatin sites.

    Viral miRNA adaptor differentially recruits miRNAs to target mRNAs through alternative base-pairing

    Carlos Gorbea et al.
    iRICC, a new method to identify RNA-RNA interactions in vivo, provides mechanistic insight into the function of a viral non-coding RNA.

    Importance of miRNA stability and alternative primary miRNA isoforms in gene regulation during Drosophila development

    Li Zhou et al.
    Selective degradation of mature miRNAs shapes temporal miRNA expression patterns and is important for proper regulation of target genes to support normal development of Drosophila embryos.

    A population of innate myelolymphoblastoid effector cell expanded by inactivation of mTOR complex 1 in mice

    Fei Tang et al.
    A novel population of hematopoietic cells unmasked by mTORC1 inactivation reveals a new mechanism of innate immune tolerance and a new consequence of defective hematopoiesis.

    TWIST1 and chromatin regulatory proteins interact to guide neural crest cell differentiation

    Xiaochen Fan et al.
    Network propagation connects TWIST1 with epigenetic regulators CHD7, CHD8, and WHSC1, which collectively promote the bias toward neural crest while suppressing neural stem cell programmes, and subsequently enhance ectomesenchyme potential.

    The transcriptional elongation rate regulates alternative polyadenylation in yeast

    Joseph V Geisberg et al.
    The elongation rate of RNA polymerase II broadly affects the profile of poly(A) sites, and hence 3' mRNA isoforms, and it can mediate alternative polyadenylation in response to environmental conditions.

    An alternative splicing program promotes adipose tissue thermogenesis

    Santiago Vernia et al.
    NOVA pre-mRNA spacing factors suppress adipose tissue energy expenditure.

    Natural variation in stochastic photoreceptor specification and color preference in Drosophila

    Caitlin Anderson et al.
    Binding site affinity and transcription factor levels are finely tuned in nature to regulate stochastic expression, setting the ratio of alternative photoreceptor fates and determining color preference.

    wtf genes are prolific dual poison-antidote meiotic drivers

    Nicole L Nuckolls et al.
    Selfish wtf meiotic drive genes use overlapping transcripts to encode both a trans-acting poison to kill gametes that do not inherit the gene and a gamete-autonomous antidote to specifically rescue the gametes that do.

    Epigenetic reprogramming rewires transcription during the alternation of generations in Arabidopsis

    Michael Borg et al.
    Epigenetic reprogramming of the distinct repressive marks H3K27me3 or H3K9me2 guides the transition between the haploid and diploid life forms that encompass the life cycle of land plants.
