    Cryo-EM structures of the human glutamine transporter SLC1A5 (ASCT2) in the outward-facing conformation

    Xiaodi Yu et al.
    Cryo-EM structures of unliganded SLC1A5 and its complex with glutamine in outward-facing state provide insights into the substrate specificity and transport mechanism and will be helpful for developing selective inhibitors.

    miR-34a is a microRNA safeguard for Citrobacter-induced inflammatory colon oncogenesis

    Lihua Wang et al.
    miR-34a prevents inflammation-induced colonic regeneration from oncogenesis by simultaneously targeting processes in both immune and epithelial cells, including T helper 17 cell differentiation, recruitment, and IL-17 induced epithelial proliferation.

    Hyperosmotic stress memory in Arabidopsis is mediated by distinct epigenetically labile sites in the genome and is restricted in the male germline by DNA glycosylase activity

    Anjar Wibowo et al.
    Transient adaptation to environmental fluctuations in plants is mediated through discrete epigenetic changes.

    Consensus designs and thermal stability determinants of a human glutamate transporter

    Erica Cirri et al.
    A fast evolutionary approach to engineer membrane protein kinetic stability yields folded excitatory neurotransmitter transporters and provides insights into their denaturing pathway.

    Nrg1 is an injury-induced cardiomyocyte mitogen for the endogenous heart regeneration program in zebrafish

    Matthew Gemberling et al.
    Neuregulin1 is induced upon cardiac injury in adult zebrafish, and is sufficient to drive massive proliferative growth of the heart.

    The transcription factors Runx3 and ThPOK cross-regulate acquisition of cytotoxic function by human Th1 lymphocytes

    Yasmina Serroukh et al.
    The acquisition of cytotoxic function by human CD4 T cells is an integral part of the T helper 1 differentiation pathway and is limited by the transcription factor ThPOK.

    GLO-Roots: an imaging platform enabling multidimensional characterization of soil-grown root systems

    Rubén Rellán-Álvarez et al.
    A luminescence-based imaging system is presented that allows soil-based environmental stimuli to be studied in root systems under physiologically relevant conditions.

    Environmental cystine drives glutamine anaplerosis and sensitizes cancer cells to glutaminase inhibition

    Alexander Muir et al.
    Cell culture models widely used in cancer research do not reflect metabolism in tumors; by altering culture systems to better model tumor metabolism we find that environmental cystine promotes tumor glutamine metabolism.

    Antigen receptor control of methionine metabolism in T cells

    Linda V Sinclair et al.
    Antigen receptor control of methionine transport is critical to co-ordinate protein synthesis and the production of methyl donors for nucleotide and protein methylations which are required for T cell differentiation.

    Autocrine regulation of stomatal differentiation potential by EPF1 and ERECTA-LIKE1 ligand-receptor signaling

    Xingyun Qi et al.
    The stomatal precursor cell uses autocrine peptide-receptor kinase signaling to self-inhibit its differentiation potential in order to ensure proper stomatal development on the plant epidermis.
