    Nucleolar dynamics and interactions with nucleoplasm in living cells

    Christina M Caragine, Shannon C Haley, Alexandra Zidovska
    The nucleoplasm surrounding nucleoli in living cells plays a key role in nucleolar dynamics and shape fluctuations in vivo.

    Loss of adaptive capacity in asthmatic patients revealed by biomarker fluctuation dynamics after rhinovirus challenge

    Anirban Sinha, René Lutter ... Edgar Delgado Eckert
    Fluctuation of biomarkers is a novel way of studying system stability during stable and unstable states of health and disease, revealing the systems' ability to cope with external perturbations.

    The DNA-binding protein HTa from Thermoplasma acidophilum is an archaeal histone analog

    Antoine Hocher, Maria Rojec ... Tobias Warnecke
    In Thermoplasma acidophilum, an archaeon without histones, a DNA-binding protein acquired from bacteria via horizontal gene transfer mediates histone-like chromatin architecture.

    Soluble PD-L1 generated by endogenous retroelement exaptation is a receptor antagonist

    Kevin W Ng, Jan Attig ... George Kassiotis
    An ancient integration of an endogenous retroelement in the gene encoding PD-L1 is exapted to generate a soluble form that antagonises the suppressive function of the membrane-bound form.

    Novel charged sodium and calcium channel inhibitor active against neurogenic inflammation

    Seungkyu Lee, Sooyeon Jo ... Bruce P Bean
    A cationic molecule derived from an uncharged Cav2.2 calcium channel inhibitor powerfully inhibits both sodium and calcium channels with extracellular application and inhibits both pain and neurogenic inflammation.

    Apolipoprotein M-bound sphingosine-1-phosphate regulates blood–brain barrier paracellular permeability and transcytosis

    Mette Mathiesen Janiurek, Rana Soylu-Kucharz ... Martin Lauritzen
    Shortage of blood-borne apolipoprotein-M–bound sphingosine-1-phosphate, which accompanies various brain disorders, causes paracellular leak and increase in transcytosis at the blood–brain barrier, which can be reversed, thus is of clinical relevance.

    Maternally regulated gastrulation as a source of variation contributing to cavefish forebrain evolution

    Jorge Torres-Paz, Julien Leclercq, Sylvie Rétaux
    Phenotypic evolution can originate from variations in very precocious developmental events, starting even before fecundation, during the fabrication of the egg in the mother's gonad.

    Lactate-mediated epigenetic reprogramming regulates formation of human pancreatic cancer-associated fibroblasts

    Tushar D Bhagat, Dagny Von Ahrens ... Amit Verma
    Lactate in pancreatic cancer micro-environment can lead to TET enzyme activation and loss of DNA methylation seen in cancer associated fibroblasts.

    Electric field causes volumetric changes in the human brain

    Miklos Argyelan, Leif Oltedal ... Christopher Abbott
    The electroconvulsive therapy induced electric field magnitude and laterality is related to volumetric increases in cortical and subcortical structures, but the association with clinical outcomes remains elusive.

    Deamidation disrupts native and transient contacts to weaken the interaction between UBC13 and RING-finger E3 ligases

    Priyesh Mohanty, Rashmi Agrata ... Ranabir Das
    Post-translational modifications regulate transient protein-protein interactions to disrupt Ubiquitin enzyme/ligase complexes, a strategy used by Shigella to inactivate the host immune response.
