    MEIS-mediated suppression of human prostate cancer growth and metastasis through HOXB13-dependent regulation of proteoglycans

    Calvin VanOpstall, Srikanth Perike ... Donald J Vander Griend
    The HOXB13 binding partner MEIS1 suppresses prostate cancer proliferation, invasion, and metastasis by promoting expression of the anti-oncogenic extracellular proteoglycan Decorin.

    Aberrant corticosteroid metabolism in tumor cells enables GR takeover in enzalutamide resistant prostate cancer

    Jianneng Li, Mohammad Alyamani ... Nima Sharifi
    Prostate cancer resistance to androgen receptor antagonist therapy occurs by way of tumors impeding local glucocorticoid metabolism and inactivation and thereby permitting sustained glucocorticoids to stimulate up-regulated glucocorticoid receptor.

    GCN2 eIF2 kinase promotes prostate cancer by maintaining amino acid homeostasis

    Ricardo A Cordova, Jagannath Misra ... Kirk A Staschke
    The ISR kinase GCN2 is critical for maintaining tumor amino acid levels to facilitate growth, suggesting a novel therapeutic strategy for the treatment of prostate cancer by inducing starvation for essential amino acids.

    CREB5 reprograms FOXA1 nuclear interactions to promote resistance to androgen receptor-targeting therapies

    Justin H Hwang, Rand Arafeh ... William C Hahn
    A comprehensive molecular interrogation of CREB5 interactions identified changes in protein and chromatin interactions of FOXA1 that promoted therapy resistance in prostate cancer cells.

    TLE3 loss confers AR inhibitor resistance by facilitating GR-mediated human prostate cancer cell growth

    Sander AL Palit, Daniel Vis ... Michiel S van der Heijden
    A mechanistic link between TLE3 loss and glucocorticoid receptor-mediated androgen receptor inhibitor resistance supports the rationale to target GR during anti-hormonal treatment in castrate-resistant prostate cancer.

    A comparative study of the cryo-EM structures of Saccharomyces cerevisiae and human anaphase-promoting complex/cyclosome (APC/C)

    Ester Vazquez-Fernandez, Jing Yang ... David Barford
    The yeast APC/C cryo-EM structure reveals substantial similarities with the human APC/C structure but also important differences in mechanisms of phosphorylation-dependent regulation and activation by coactivators.

    FLEXIQuant-LF to quantify protein modification extent in label-free proteomics data

    Christoph N Schlaffner, Konstantin Kahnert ... Hanno Steen
    FLEXIQuant-LF provides the framework to enable large-scale identification of differentially modified peptides and quantification of their modification extent in label-free mass spectrometry data without prior knowledge of the modification type.
