    The mTORC1-mediated activation of ATF4 promotes protein and glutathione synthesis downstream of growth signals

    Margaret E Torrence et al.
    ATF4 is a metabolic effector of mTORC1 signaling, co-opted to induce gene targets involved in amino acid synthesis, uptake, and tRNA charging, contributing to mTORC1-driven protein and glutathione synthesis.

    Reprogramming of translation in yeast cells impaired for ribosome recycling favors short, efficiently translated mRNAs

    Swati Gaikwad et al.
    A mutant impaired for ribosome recycling exhibits translational reprogramming wherein strong mRNAs outcompete weak mRNAs, also observed when preinitiation complexes are diminished by eIF2α phosphorylation or 40S ribosomal subunit depletion.

    eIF2B conformation and assembly state regulate the integrated stress response

    Michael Schoof et al.
    eIF2-P activates the integrated stress response by inducing a conformational change in eIF2B that decreases substrate (eIF2) binding and reduces eIF2B's catalytic activity.

    Prolonging the integrated stress response enhances CNS remyelination in an inflammatory environment

    Yanan Chen et al.
    Oligodendrocytes with an enhanced ability to withstand cytotoxic stress display an increased capacity to remyelinate demyelination lesions of the CNS in the presence of an inflammatory environment.

    MITF reprograms the extracellular matrix and focal adhesion in melanoma

    Ramile Dilshat et al.
    Analysis of knockout and knockdown melanoma cells and TCGA melanoma data shows that the microphthalmia-associated transcription factor (MITF) is a major repressor of extracellular matrix (ECM) and focal adhesion genes.
