    Chlamydia trachomatis-containing vacuole serves as deubiquitination platform to stabilize Mcl-1 and to interfere with host defense

    Annette Fischer, Kelly S Harrison ... Thomas Rudel
    Obligate intracellular Chlamydia secrete a deubiquitinating enzyme (Cdu1) into the membrane of the Chlamydia-containing vacuole to deubiquitinate selected host proteins and support the survival of the bacteria during genital infection.

    Epstein-Barr virus ensures B cell survival by uniquely modulating apoptosis at early and late times after infection

    Alexander M Price, Joanne Dai ... Micah A Luftig
    Epstein-Barr virus hijacks host anti-apoptotic machinery to ensure survival during latent infection.

    Epistatic mutations in PUMA BH3 drive an alternate binding mode to potently and selectively inhibit anti-apoptotic Bfl-1

    Justin M Jenson, Jeremy A Ryan ... Amy E Keating
    Short peptides that bind tightly to anti-apoptotic protein Bfl-1 but not other Bcl-2 family members provide a tool for diagnosing cancer cell survival mechanisms and a lead for developing new therapeutics.

    Targeting MYC dependency in ovarian cancer through inhibition of CDK7 and CDK12/13

    Mei Zeng, Nicholas P Kwiatkowski ... Nathanael S Gray
    A multi-transcriptional CDKs inhibitor suppresses MYC and induces regression of ovarian tumors, indicating that targeting CDK7, 12, 13 with THZ1 may be an effective approach for treating MYC-dependent malignancies.

    Yap1 safeguards mouse embryonic stem cells from excessive apoptosis during differentiation

    Lucy LeBlanc, Bum-Kyu Lee ... Jonghwan Kim
    During ES cell differentiation, Yap1 directly regulates apoptosis-related genes like Bcl-2 and Mcl-1 to attenuate apoptosis and promote cell survival to allow for successful cell fate changes.

    Bid maintains mitochondrial cristae structure and function and protects against cardiac disease in an integrative genomics study

    Christi T Salisbury-Ruf, Clinton C Bertram ... Sandra S Zinkel
    An integrative approach, combining genetic mouse and large-scale human genetics studies, was used to reveal a novel role for the Bcl-2 protein Bid in maintenance of mitochondrial function that alters susceptibility to myocardial infarction.

    Unifying the known and unknown microbial coding sequence space

    Chiara Vanni, Matthew S Schechter ... Antonio Fernàndez-Guerra
    A newly developed computational framework provides an overview of the extent, diversity, and relevance of the genes of unknown function in genomes and metagenomes.

    The carboxyl-terminal sequence of PUMA binds to both anti-apoptotic proteins and membranes

    James M Pemberton, Dang Nguyen ... David W Andrews
    A second anti-apoptotic protein binding site in PUMA confers resistance to BH3 mimetic drugs and binds the protein to membranes.

    IL-4 and helminth infection downregulate MINCLE-dependent macrophage response to mycobacteria and Th17 adjuvanticity

    Judith Schick, Meltem Altunay ... Roland Lang
    The expression of DECTIN-2 family C-type lectin receptors on macrophages and monocytes is inhibited by the Th2 cytokine IL-4, which suggests a mechanism for inhibition of Th17 responses to MINCLE-dependent vaccination responses by underlying helminth infection.

    The carboxyl-terminal sequence of bim enables bax activation and killing of unprimed cells

    Xiaoke Chi, Dang Nguyen ... David W Andrews
    The C-terminal membrane binding domain of Bim is shown to interact with and activate Bim enabling it to kill cells not dependent on anti-apoptotic proteins for survival.
