    Down the Penrose stairs, or how selection for fewer recombination hotspots maintains their existence

    Zachary Baker, Molly Przeworski, Guy Sella
    Modeling the evolution of PRDM9 in light of recent results implicating the importance of PRDM9 binding symmetry suggests the advantage of new PRMD9 alleles is in limiting the number of binding sites used effectively rather than increasing net binding.

    Polysome-CAGE of TCL1-driven chronic lymphocytic leukemia revealed multiple N-terminally altered epigenetic regulators and a translation stress signature

    Ariel Ogran, Tal Havkin-Solomon ... Rivka Dikstein
    Examination of the changes in the transcription start site selection in TCL1-driven chronic lymphocytic leukemia and their impact on mRNA translation revealed a marked elevation of intra-genic cryptic promoters, which are predicted to generate multiple N-terminally truncated or modified proteins.

    The dual role of amyloid-β-sheet sequences in the cell surface properties of FLO11-encoded flocculins in Saccharomyces cerevisiae

    Clara Bouyx, Marion Schiavone ... Jean Marie François
    The role of amyloid-β-aggregation sequence and of the various domains in the physiological function of the FLO11-encoded adhesin in the yeast Saccharomyces cerevisiae are disclosed in this report.

    Loss of MGA repression mediated by an atypical polycomb complex promotes tumor progression and invasiveness

    Haritha Mathsyaraja, Jonathen Catchpole ... Robert N Eisenman
    The MYC transcription factor network member MGA is a subunit of a non-canonical Polycomb complex, which, when inactivated, accelerates tumorigenesis in mouse models of cancer and proliferation in colon organoids.

    shinyDepMap, a tool to identify targetable cancer genes and their functional connections from Cancer Dependency Map data

    Kenichi Shimada, John A Bachman ... Timothy J Mitchison
    shinyDepMap helps users explore the essentiality, selectivity, and function of the genes across hundreds of cancer cell lines and identify cancer drug targets.

    Systematic identification of cis-regulatory variants that cause gene expression differences in a yeast cross

    Kaushik Renganaath, Rockie Chong ... Frank W Albert
    Yeast promoters can harbor multiple natural DNA variants that influence gene expression, interact genetically, evolve under negative selection, alter transcription factor motifs, and remain challenging to predict.

    PRDM9 activity depends on HELLS and promotes local 5-hydroxymethylcytosine enrichment

    Yukiko Imai, Mathilde Biot ... Bernard de Massy
    Biochemical and genetic approaches uncover a chromatin remodeler for PRDM9 binding and the parallel local epigenetic modification of cytosines in mouse spermatocytes.

    ZCWPW1 is recruited to recombination hotspots by PRDM9 and is essential for meiotic double strand break repair

    Daniel Wells, Emmanuelle Bitoun ... Simon R Myers
    ZCWPW1 has co-evolved with PRDM9, in particular the PRDM9-SET domain, and although not involved in PRDM9's role in positioning recombination events, it is required for PRDM9's role in pairing chromosomes.

    Sexual Reproduction: Reading the epigenetic code for exchanging DNA

    Mathilde Biot, Bernard de Massy
    Three independent studies show that a protein called ZCWPW1 is able to recognize the histone modifications that initiate the recombination of genetic information during meiosis.
