    Implications of being born late in the active season for growth, fattening, torpor use, winter survival and fecundity

    Britta Mahlert et al.
    Being born late in the active season is associated with a fast life history in a hibernating species, the garden dormouse (Eliomys quercinus).

    Erythropoietin signaling regulates heme biosynthesis

    Jacky Chung et al.
    EPO/JAK2/PKA signaling cascade via AKAP10 relocalization to the outer mitochondrial membrane results in the phosphorylation of the terminal heme synthesis enzyme ferrochelatase, which contributes to heme production in red cells.

    Novel mechanism of metabolic co-regulation coordinates the biosynthesis of secondary metabolites in Pseudomonas protegens

    Qing Yan et al.
    The production of two secondary metabolites is co-regulated in a bacterium via an intermediate in one pathway that is converted into signals to activate the second pathway.

    Principles of cellular resource allocation revealed by condition-dependent proteome profiling

    Eyal Metzl-Raz et al.
    Steadily growing cells prepare for conditions that demand increased translation by producing excess ribosomes, at the expense of lower steady-state growth rate.

    PPP1R15A-mediated dephosphorylation of eIF2α is unaffected by Sephin1 or Guanabenz

    Ana Crespillo-Casado et al.
    The notion that the drug-like small molecule Sephin1 protects against protein misfolding by selectively disrupting a cellular phosphatase is refuted.

    The genetic basis of aneuploidy tolerance in wild yeast

    James Hose et al.
    A single gene allele underlies differences in aneuploidy tolerance in yeast.

    Misfolded GPI-anchored proteins are escorted through the secretory pathway by ER-derived factors

    Eszter Zavodszky, Ramanujan S Hegde
    ER-resident chaperones and cargo receptors make excursions to the cell surface and endocytic compartments when they accompany misfolded clients to lysosomes for degradation.

    Mechano-redox control of integrin de-adhesion

    Freda Passam et al.
    Ligand binding, force and chemistry combine to control the function of a cell surface receptor.

    iTAP, a novel iRhom interactor, controls TNF secretion by policing the stability of iRhom/TACE

    Ioanna Oikonomidi et al.
    Secretion of the inflammatory cytokine TNF requires a protein called iTAP/FrmD8, which controls the cell surface stability of the TNF shedding machinery, iRhom2 and TACE/ADAM17.
