    Network-wide abnormalities explain memory variability in hippocampal amnesia

    Georgios PD Argyropoulos, Clare Loane ... Christopher R Butler
    Hippocampal damage is associated with changes across the extended hippocampal system, and these may explain variability in memory between patients presenting with hippocampal amnesia.

    Altered functional connectivity during speech perception in congenital amusia

    Kyle Jasmin, Frederic Dick ... Adam Taylor Tierney
    Individuals with amusia, who have unreliable pitch processing, show decreased functional connectivity between right auditory and left language-related cortex during speech perception, demonstrating a neural basis for compensatory dimensional weighting.

    Monoubiquitination by the human Fanconi anemia core complex clamps FANCI:FANCD2 on DNA in filamentous arrays

    Winnie Tan, Sylvie van Twest ... Andrew J Deans
    Biochemical reconstitution experiments uncover the ubiquitin-mediated function of a DNA repair protein, key to the understanding of Fanconi Anemia, a cancer-associated bone marrow failure syndrome.

    Hyperphosphatemia increases inflammation to exacerbate anemia and skeletal muscle wasting independently of FGF23-FGFR4 signaling

    Brian Czaya, Kylie Heitman ... Christian Faul
    Hyperphosphatemia, by itself and in the context of chronic kidney disease, contributes to iron restrictive anemia by directly targeting the liver and elevating proinflammatory cytokines and hepcidin, which contributes to widespread tissue injury, such as skeletal muscle wasting.

    Human hippocampal CA3 damage disrupts both recent and remote episodic memories

    Thomas D Miller, Trevor T-J Chong ... Clive R Rosenthal
    Human hippocampal cornu ammonis 3 damage impairs both recent and remote autobiographical episodic memory, and disrupts functional integration in medial temporal lobe subsystem regions of the default network.

    A critical role for mTORC1 in erythropoiesis and anemia

    Zachary A Knight, Sarah F Schmidt ... Jeffrey M Friedman
    Transcription profiling of activated cells using Phospho-Trap, a new method for identifying activated cells, reveals a critical role for mTOR signaling in red blood cell development and the pathogenesis of anemia

    Receptor-mediated mitophagy regulates EPO production and protects against renal anemia

    Guangfeng Geng, Jinhua Liu ... Lihong Shi
    Fundc1-mediated mitophagy protects renal EPO-producing cells from myofibroblastic conversion under stresses.

    Phage resistance profiling identifies new genes required for biogenesis and modification of the corynebacterial cell envelope

    Amelia C McKitterick, Thomas G Bernhardt
    Using bacteriophages as probes, new genes involved in cell surface construction were identified in a class of bacteria that includes important pathogens like Mycobacterium tuberculosis.

    Atypical memory B-cells are associated with Plasmodium falciparum anemia through anti-phosphatidylserine antibodies

    Juan Rivera-Correa, Maria Sophia Mackroth ... Ana Rodriguez
    The association of atypical memory B-cells and autoimmune antibodies (anti-phosphatidylserine) with hemoglobin levels in malaria patients uncovers a novel mechanism for the human malaria-induced anemia previously identified in mice.
    1. Evolutionary Biology

    Intermolecular epistasis shaped the function and evolution of an ancient transcription factor and its DNA binding sites

    Dave W Anderson, Alesia N McKeown, Joseph W Thornton
    Experimental mapping of the joint sequence space of an ancient transcription factor (TF) and its DNA binding sites reveals that epistasis across the molecular interface permitted the evolution of a new and specific TF-DNA complex.
