    Phosphatidylinositol 3-kinase and COPII generate LC3 lipidation vesicles from the ER-Golgi intermediate compartment

    Liang Ge, Min Zhang, Randy Schekman
    Building on previous work (Ge et al., 2013), it is shown that the ER-Golgi intermediate compartment is a platform for the production of COPII vesicles as precursor membranes for the lipidation of LC3, which is an essential step in autophagosome biogenesis.

    NFATc1 marks articular cartilage progenitors and negatively determines articular chondrocyte differentiation

    Fan Zhang, Yuanyuan Wang ... Xianpeng Ge
    NFATc1 is identified as a molecular marker of articular cartilage progenitor cells and a transcriptional repressor of chondrocyte differentiation, providing fundamental insights into the origin and differentiation mechanism of articular chondrocytes.

    Dynamic modulation of decision biases by brainstem arousal systems

    Jan Willem de Gee, Olympia Colizoli ... Tobias H Donner
    Rapid increases in the brain’s level of alertness, or arousal, contribute to variability in decision making by reducing existing biases.

    H3K4 mono- and di-methyltransferase MLL4 is required for enhancer activation during cell differentiation

    Ji-Eun Lee, Chaochen Wang ... Kai Ge
    MLL4 (KMT2D) is a major mammalian H3K4 mono- and di-methyltransferase that is essential for enhancer activation, cell-type-specific gene expression, and cell differentiation.

    Maternal obesity may disrupt offspring metabolism by inducing oocyte genome hyper-methylation via increased DNMTs

    Shuo Chao, Jun Lu ... Zhao-Jia Ge
    Maternal obesity mouse model reveal that melatonin deficiency causes the genomic hyper-methylation of oocytes via increasing the expression of DNA methyltransferases.

    The ER–Golgi intermediate compartment is a key membrane source for the LC3 lipidation step of autophagosome biogenesis

    Liang Ge, David Melville ... Randy Schekman
    A cell-free biochemical assay for protein lipidation identifies the ER–Golgi intermediate compartment as a key early station in the formation of an autophagosome.

    Polypyrimidine tract binding protein 1 protects mRNAs from recognition by the nonsense-mediated mRNA decay pathway

    Zhiyun Ge, Bao Lin Quek ... J Robert Hogg
    The RNA-binding protein PTBP1 is recruited to sites near stop codons in retroviral and human mRNAs, shielding them from detection and degradation by the nonsense-mediated mRNA decay pathway.

    Humans strategically shift decision bias by flexibly adjusting sensory evidence accumulation

    Niels A Kloosterman, Jan Willem de Gee ... Johannes Jacobus Fahrenfort
    Decision-makers are able to intentionally control neural excitability to strategically bias sensory evidence accumulation towards the decision bound that maximizes reward within a given ecological context.

    Choice history biases subsequent evidence accumulation

    Anne E Urai, Jan Willem de Gee ... Tobias H Donner
    Choice history signals bias the interpretation of current sensory input, akin to shifting endogenous attention toward (or away from) the previously selected interpretation.

    Pupil-linked phasic arousal predicts a reduction of choice bias across species and decision domains

    Jan Willem de Gee, Konstantinos Tsetsos ... Tobias H Donner
    Across species and domains of decision-making, pupil-linked phasic arousal predicts suppression biases in the accumulation of evidence leading up to a choice.
