    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.

    Glial and neuronal Semaphorin signaling instruct the development of a functional myotopic map for Drosophila walking

    Durafshan Sakeena Syed, Swetha B.M. Gowda ... K VijayRaghavan
    Signaling from glia and nerves regulate the development of axonal and dendritic motor neuron architecture, needed for walking in the fruit fly species Drosophila.

    Bim escapes displacement by BH3-mimetic anti-cancer drugs by double-bolt locking both Bcl-XL and Bcl-2

    Qian Liu, Elizabeth J Osterlund ... David William Andrews
    The pro-apoptotic BH3-protein Bim contains two distinct binding sites for anti-apoptotic proteins that together confer resistance of Bim/Bcl-2 and Bim/Bcl-XL complexes to BH3-mimetic drugs under development for use in humans.

    Human DNA2 possesses a cryptic DNA unwinding activity that functionally integrates with BLM or WRN helicases

    Cosimo Pinto, Kristina Kasaciunaite ... Petr Cejka
    The nuclease of hDNA2 limits its processive DNA unwinding capacity; the helicase function becomes stimulatory when hDNA2 is in complex with BLM or WRN helicase to degrade dsDNA.

    On cross-frequency phase-phase coupling between theta and gamma oscillations in the hippocampus

    Robson Scheffer-Teixeira, Adriano BL Tort
    Phase-locking of hippocampal theta and gamma waves has been proposed to support memory formation, but an analysis using robust statistical methods finds no convincing evidence for the phenomenon.

    Mechanisms and functions of respiration-driven gamma oscillations in the primary olfactory cortex

    Joaquin Gonzalez, Pablo Torterolo, Adriano BL Tort
    Computational analyses of in-vivo cerebral activity show that gamma oscillations in the olfactory cortex originate from local feedback inhibition following each sniff and serve to segregate competing odor representations through a winner-take-all process, providing an optimal window to decode odor.

    Inter-membrane association of the Sec and BAM translocons for bacterial outer-membrane biogenesis

    Sara Alvira, Daniel W Watkins ... Ian Collinson
    The protein translocation apparatus of the inner- (Sec) and outer-membrane (BAM) interact to form a trans-periplasmic super-complex capable of long-range, PMF-dependent conformational changes to facilitate efficient outer-membrane protein maturation.

    Metastasis of colon cancer requires Dickkopf-2 to generate cancer cells with Paneth cell properties

    Jae Hun Shin, Jooyoung Park ... Alfred LM Bothwell
    DKK2 is crucial for the development of lysozyme-expressing cancer cells with Paneth cell characteristics necessary for liver metastasized colon cancer growth.

    Deletion of Stk11 and Fos in mouse BLA projection neurons alters intrinsic excitability and impairs formation of long-term aversive memory

    David Levitan, Chenghao Liu ... Sacha B Nelson
    Stk11 and Fos expression plays an important role in CTA long-term memory formation by modulating the intrinsic excitability of BLApn.

    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.
