    Pharmacological brake-release of mRNA translation enhances cognitive memory

    Carmela Sidrauski, Diego Acosta-Alvear ... Peter Walter
    A compound that prevents stressors such as UV light and viral infection from downregulating protein synthesis inside cells improves memory performance in mice.

    Global cellular response to chemotherapy-induced apoptosis

    Arun P Wiita, Etay Ziv ... James A Wells
    The simultaneous monitoring of transcription, translational control, protein production and proteolysis in the same system can improve our understanding of how cancer cells respond to chemotherapy.

    Structural basis of GSK-3 inhibition by N-terminal phosphorylation and by the Wnt receptor LRP6

    Jennifer L Stamos, Matthew Ling-Hon Chu ... William I Weis
    Phosphorylation of the Wnt receptor LRP6 directly inhibits glycogen synthase kinase-3 by acting as a pseudosubstrate that stabilizes an active conformation of the enzyme, identical to autoinhibition by phosphorylation of its N terminus.

    MUL1 acts in parallel to the PINK1/parkin pathway in regulating mitofusin and compensates for loss of PINK1/parkin

    Jina Yun, Rajat Puri ... Ming Guo
    By reducing mitochondrial fusion, MUL1 compensates for the mutations in PINK1 or parkin that underlie certain cases of Parkinson's disease.

    Pharmacological inhibition of cystine–glutamate exchange induces endoplasmic reticulum stress and ferroptosis

    Scott J Dixon, Darpan N Patel ... Brent R Stockwell
    Erastin and sorafenib inhibit system xc- and induce ER stress, suggesting these may be useful tools for probing the functions of system xc- and its role in inducing ER stress and ferroptosis.

    Reversal of β cell de-differentiation by a small molecule inhibitor of the TGFβ pathway

    Barak Blum, Adam N Roose ... Douglas A Melton
    Loss of mature β cell identity in diabetes can be prevented and rescued by small molecule inhibitors of the TGFβ pathway.

    Genome-wide regulatory dynamics of translation in the Plasmodium falciparum asexual blood stages

    Florence Caro, Vida Ahyong ... Joseph L DeRisi
    Ribosome profiling has bridged the knowledge gap between transcription and translation during malaria blood stage development and provided a comprehensive gene expression resource for this parasite.

    Translation of 5′ leaders is pervasive in genes resistant to eIF2 repression

    Dmitry E Andreev, Patrick BF O'Connor ... Pavel V Baranov
    Most of the mRNAs whose translation is resistant to the stress-induced repression of protein synthesis contain upstream open reading frames that are efficiently translated under normal conditions.

    dPob/EMC is essential for biosynthesis of rhodopsin and other multi-pass membrane proteins in Drosophila photoreceptors

    Takunori Satoh, Aya Ohba ... Akiko K Satoh
    A membrane protein complex in the endoplasmic reticulum is a key factor for the biogenesis of multi-pass transmembrane proteins, including Rh1, and its loss causes retinal degeneration.
