    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.

    A powerful drug combination strategy targeting glutamine addiction for the treatment of human liver cancer

    Haojie Jin et al.
    Combination of glutaminase inhibitor CB-839 and ASCT2 inhibitor V-9302 showed efficient antitumor effect against glutamine addicted liver cancer cells via glutathione depletion and reactive oxygen species (ROS) induction.

    Smchd1 is a maternal effect gene required for genomic imprinting

    Iromi Wanigasuriya et al.
    Imprinted gene expression is set up during a critical window of early embryonic development, by the translation of parental imprints by oocyte-supplied Smchd1 into allele-specific gene silencing.

    Repurposing of KLF5 activates a cell cycle signature during the progression from a precursor state to oesophageal adenocarcinoma

    Connor Rogerson et al.
    Genome-wide redistribution of KLF5 binding leads to activation of a cell cycle gene expression programme and proliferation control in oesophageal cancer.

    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.

    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.

    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.

    Large domain movements through the lipid bilayer mediate substrate release and inhibition of glutamate transporters

    Xiaoyu Wang, Olga Boudker
    Substrate releasing or inhibitor binding on the intracellular side of a glutamate transporter homologue require movements of the transport domain through the lipid membrane, which undergoes adaptive deformations.
