    Blockade of the LRP16-PKR-NF-κB signaling axis sensitizes colorectal carcinoma cells to DNA-damaging cytotoxic therapy

    Xiaolei Li et al.
    Leukemia-Related Protein 16 (LRP16), a member of the macro domain family, plays a crucial role in orchestrating genotoxicity-initiated NF-κB signaling in the colon and the pathophysiological relevance of NF-κB activation induced by LRP16 in colonic cell survival/recovery from extrinsic DNA damage.

    Cytokinin transfer by a free-living mirid to Nicotiana attenuata recapitulates a strategy of endophytic insects

    Christoph Brütting et al.
    Cytokinin-dependent manipulation of plant metabolism is a strategy employed not only by gallers and leaf-miners but also by a free-living insect, Tupiocoris notatus, which directly transfers cytokinins at feeding sites to manipulate its host plant.

    Proteostasis collapse, a hallmark of aging, hinders the chaperone-Start network and arrests cells in G1

    David F Moreno et al.
    Cells accumulate damaged proteins during aging and, by compromising the function of chaperones in folding newly synthesized G1 cyclins, proteostasis breakdown inhibits cell-cycle entry and drives yeast cells into senescence.

    Global analysis of p53-regulated transcription identifies its direct targets and unexpected regulatory mechanisms

    Mary Ann Allen et al.
    The first global analysis of the effects of the transcription factor p53 on RNA synthesis illuminates several novels aspects of the molecular mechanism of action of this potent tumor suppressor.

    Mycobacterium tuberculosis exploits host ATM kinase for survival advantage through SecA2 secretome

    Savita Lochab et al.
    Mycobacterium tuberculosis (Mtb), effectors secreted through SecA2 pathway cause double strand breaks (DSBs) in the host DNA, which in turn activates ATM kinase to gain survival advantages, through Akt.

    Naked mole-rat mortality rates defy Gompertzian laws by not increasing with age

    J Graham Ruby et al.
    Unlike all other mammals studied to date, the age-specific risk of mortality for naked mole-rats did not increase over decades of life, identifying this species as a non-aging mammal.

    Smad4 restricts differentiation to promote expansion of satellite cell derived progenitors during skeletal muscle regeneration

    Nicole D Paris et al.
    Ablation of canonical TGFβ signaling in muscle stem cells at any age is detrimental, and not beneficial, to effective skeletal muscle regeneration due to the promotion of premature fate commitment at the expense of progenitor amplification.

    Quantitative mapping of human hair greying and reversal in relation to life stress

    Ayelet M Rosenberg et al.
    A method to profile hair pigmentation patterns establishes a new approach for psychobiological studies and links metabolic changes to greying in humans.

    Mammalian genes induce partially reprogrammed pluripotent stem cells in non-mammalian vertebrate and invertebrate species

    Ricardo Antonio Rosselló et al.
    Cells from vertebrate and invertebrate model systems can be reprogrammed into stem-like cells using mouse genes.

    Whole-genome sequencing analysis of semi-supercentenarians

    Paolo Garagnani et al.
    Genetic variants located in DNA repair genes and a reduced burden of somatic mutations protect the oldest living persons from age-related diseases, allowing an healthy aging phenotype.
