    Episode 54: February 2019

    In this episode, we hear about colour vision in bats, frog vocal systems, ageing, problematic cell lines and how larger neurons could lead to a higher IQ.
    1. Chromosomes and Gene Expression

    Aurora-A mediated histone H3 phosphorylation of threonine 118 controls condensin I and cohesin occupancy in mitosis

    Candice L Wike et al.
    A histone modification that alters the nucleosome structure occurs in mitosis and promotes chromosome packaging and the timely removal of condensin I and cohesion, to achieve chromosome segregation.
    1. Stem Cells and Regenerative Medicine

    Distinct SoxB1 networks are required for naïve and primed pluripotency

    Andrea Corsinotti et al.
    Genetic manipulations show that endogenous transcription factors of the SoxB1 class act redundantly to maintain primed pluripotency and reveal differential effects on transitions between pluripotent and differentiation states.

    Mitochondrial fusion is required for spermatogonial differentiation and meiosis

    Grigor Varuzhanyan et al.
    Mitochondrial fusion enables a metabolic transition during spermatogenesis.

    Neuron-glia signaling in developing retina mediated by neurotransmitter spillover

    Juliana M Rosa et al.
    Retinal waves are correlated with calcium transients in Müller cells, demonstrating that spontaneous activity encompasses both neuronal and glial networks during a crucial period of retinal development.

    A non-canonical mechanism for Crm1-export cargo complex assembly

    Ute Fischer et al.
    Slx9 is a newly discovered type of RanGTP-binding protein required for Crm1-mediated nuclear export.

    A surface proton antenna in carbonic anhydrase II supports lactate transport in cancer cells

    Sina Ibne Noor et al.
    Carbonic anhydrase II features a surface proton antenna that exclusively mediates proton exchange with monocarboxylate transporters to facilitate proton-coupled lactate transport in cancer cells.

    Epistatic mutations in PUMA BH3 drive an alternate binding mode to potently and selectively inhibit anti-apoptotic Bfl-1

    Justin M Jenson et al.
    Short peptides that bind tightly to anti-apoptotic protein Bfl-1 but not other Bcl-2 family members provide a tool for diagnosing cancer cell survival mechanisms and a lead for developing new therapeutics.
    1. Computational and Systems Biology

    Building accurate sequence-to-affinity models from high-throughput in vitro protein-DNA binding data using FeatureREDUCE

    Todd R Riley et al.
    A biophysically principled algorithm can build quantitative models of protein-DNA binding specificity of unprecedented accuracy from a leading type of high-throughput in vitro binding data.

    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.
