    Evolution of reduced co-activator dependence led to target expansion of a starvation response pathway

    Bin Z He et al.
    The phosphate starvation response network in a commensal yeast evolved to expand its downstream targets via changes in the main transcription factor's dependence on its co-activator, potentially altering the physiological response.

    Stress induced gene expression drives transient DNA methylation changes at adjacent repetitive elements

    David Secco et al.
    Phosphate starvation in rice induces widespread, but transient, modulation of DNA methylation near stress responsive genes that is independent from the RNA-directed DNA methylation pathway.

    Two bifunctional inositol pyrophosphate kinases/phosphatases control plant phosphate homeostasis

    Jinsheng Zhu et al.
    Genetic and biochemical analysis of two enzymes reveals that inositol pyrophosphate signaling molecules allow plants to sense and regulate cellular phosphate levels, and to take up more phosphate when needed.

    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.

    Multiplex image-based autophagy RNAi screening identifies SMCR8 as ULK1 kinase activity and gene expression regulator

    Jennifer Jung et al.
    An image-based multiplex autophagosome RNAi screen targeting all Rab GTPases as well as their GAPs and GEFs identifies the Rab GEF SMCR8 as multifaceted autophagy modulator, which regulates kinase activity and gene expression of ULK1.

    Full length RTN3 regulates turnover of tubular endoplasmic reticulum via selective autophagy

    Paolo Grumati et al.
    Full length RTN3 homodimerization mediates ER tubules fragmentation and their subsequent delivery to lysosome.

    Loss of Ptpn11 (Shp2) drives satellite cells into quiescence

    Joscha Griger et al.
    The stem cells of the postnatal muscle allow postnatal muscle growth and repair and withdraw from the cell cycle when the tyrosine phosphatase Ptpn11 (Shp2) is inhibited or mutated in mice.

    LARP1 functions as a molecular switch for mTORC1-mediated translation of an essential class of mRNAs

    Sungki Hong et al.
    LARP1 turns off and on the translation of an essential class of mRNAs by acting as a key effecter and regulator for mTORC1.

    Human biallelic MFN2 mutations induce mitochondrial dysfunction, upper body adipose hyperplasia, and suppression of leptin expression

    Nuno Rocha et al.
    Specific human mitofusin 2 mutations induce selective upper body obesity with suppressed leptin expression and severe adipose mitochondrial dysfunction.
