    Fast turnover of genome transcription across evolutionary time exposes entire non-coding DNA to de novo gene emergence

    Rafik Neme, Diethard Tautz
    Deep sequencing of transcriptomes from closely related taxa shows that the whole genome can become subject to evolutionary testing within a short time frame via de novo evolution of genes.

    Philosophy of Biology: The meanings of 'function' in biology and the problematic case of de novo gene emergence

    Diane Marie Keeling et al.
    A lexicon to help scientists and philosophers discuss the meaning of function in molecular biology more clearly is proposed.

    A de novo evolved gene in the house mouse regulates female pregnancy cycles

    Chen Xie et al.
    A female specifically expressed new protein-coding gene that has emerged out of non-coding sequences without detectable signatures of adaptive evolution affects female pregnancy cycles.

    Synteny-based analyses indicate that sequence divergence is not the main source of orphan genes

    Nikolaos Vakirlis et al.
    Homology information implicit in regions of conserved synteny allows quantification of gene origination by complete sequence divergence, revealing a larger-than-expected role for other mechanisms of origin, including de novo origination.

    Multi-step vs. single-step resistance evolution under different drugs, pharmacokinetics, and treatment regimens

    Claudia Igler et al.
    The number and effects of mutations leading to full drug resistance crucially determine treatment failure probability and should be used to inform antimicrobial treatment strategies with regard to avoidance of resistance emergence.

    An adjunctive therapy administered with an antibiotic prevents enrichment of antibiotic-resistant clones of a colonizing opportunistic pathogen

    Valerie J Morley et al.
    Cholestyramine, an FDA-approved bile acid sequestrant, can be repurposed to inactivate the antibiotic daptomycin in the gut, which prevents the emergence of transmissible antibiotic resistance in gastrointestinal Enterococcus faecium populations.

    Genetic Novelty: How new genes are born

    Urminder Singh, Eve Syrkin Wurtele
    Analysis of yeast, fly and human genomes suggests that sequence divergence is not the main source of orphan genes.

    Dynamic turnover of centromeres drives karyotype evolution in Drosophila

    Ryan Bracewell et al.
    De novo formation of centromeres creates diverse karyotypes in flies and is accompanied by rapid turnover of centromere-associated satellite repeats.

    ARID1A loss in adult hepatocytes activates β-catenin-mediated erythropoietin transcription

    Rozenn Riou et al.
    A chromatin remodeling factor cooperates with Wnt signaling pathway to transcribe erythropoietin in the adult liver, inducing its secretion and a dramatic erythropoiesis in the spleen.

    Primary and promiscuous functions coexist during evolutionary innovation through whole protein domain acquisitions

    José Antonio Escudero et al.
    The coexistence of ancestral and innovative functions is possible and fosters evolutionary innovation in events involving the acquisition of whole protein domains.
