    Horizontal transfer of whole mitochondria restores tumorigenic potential in mitochondrial DNA-deficient cancer cells

    Lan-Feng Dong et al.
    A genetic approach documents that mitochondrial DNA moves from donor cells to recipient mtDNA-depleted cells in whole mitochondria and that this restores mitochondrial respiration and the capacity of the cells to form tumours.

    Point of View: Is cell size a spandrel?

    Ariel Amir
    Analysis of experiments on bacteria suggests that the dependence of cell size on growth rate is not an adaptation but a causal consequence of a regulatory mechanism that controls DNA replication.
  1. Point of View: The sustainable professor

    Point of View: Managing a sustainable deep-sea ‘blue economy’ requires knowledge of what actually lives there

    Adrian G Glover et al.
    High-throughput, integrative taxonomy has a crucial role to play in ensuring that the resources in our oceans are managed and developed in a sustainable manner.

    Acute intermittent hypoxia enhances corticospinal synaptic plasticity in humans

    Lasse Christiansen et al.
    Acute intermittent hypoxia is a noninvasive approach that enhances corticospinal function in humans, likely through alterations in corticospinal-motoneuronal synaptic transmission.

    Proteasome storage granules protect proteasomes from autophagic degradation upon carbon starvation

    Richard S Marshall, Richard D Vierstra
    Proteasomes are protected from autophagic elimination upon carbon starvation by sequestration into cytoplasmic storage granules, which aid cell fitness by providing a cache of proteasomes that can be rapidly remobilized when carbon availability improves.

    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.

    NFATc2 enhances tumor-initiating phenotypes through the NFATc2/SOX2/ALDH axis in lung adenocarcinoma

    Zhi-Jie Xiao et al.
    NFATc2 maintains the drug-induced TIC phenotypes through trans-activating SOX2/ALDH1A1 expression and scavenging stress from ROS.

    Cellular localization of the cell cycle inhibitor Cdkn1c controls growth arrest of adult skeletal muscle stem cells

    Despoina Mademtzoglou et al.
    Ablation of the Cdkn1c cell cycle inhibitor leads to defective muscle stem cell dynamics and myogenic potential, while progressive cytoplasmic to nuclear cellular localization of the Cdkn1c protein regulates growth arrest.
