    Non-canonical function of an Hif-1α splice variant contributes to the sustained flight of locusts

    Ding Ding, Jie Zhang ... Le Kang
    The long-distance flight of locusts is greatly facilitated by a muscle-abundantly expressed Hif-1α splice variant, which remains active in normoxia and scavenges flight-induced reactive oxygen species by upregulating the expression of DJ-1 (PARK 7).

    Alternative Splicing: A new role for Hif-1α

    Mingyu Shin, Jiwon Shim
    A gene normally involved in responding to hypoxia helps to protect insect muscles during migratory flight in a non-oxygen dependent manner.

    Prolonged β-adrenergic stimulation disperses ryanodine receptor clusters in cardiomyocytes and has implications for heart failure

    Xin Shen, Jonas van den Brink ... William E Louch
    Prolonged β-adrenergic stimulation causes ryanodine receptor clusters to disperse, drastically altering the frequency and kinetics of Ca2+ release events called ‘Ca2+ sparks’ in a process that is dependent on CaMKII and PKA.

    An amphipathic helix in Brl1 is required for nuclear pore complex biogenesis in S. cerevisiae

    Annemarie Kralt, Matthias Wojtynek ... Karsten Weis
    Genetic, proteomic, and structural analyses provide insight into the role of Brl1 during nuclear pore complex biogenesis, suggesting a function in the fusion of outer and inner nuclear membranes.

    Interleukin-33 regulates the endoplasmic reticulum stress of human myometrium via an influx of calcium during initiation of labor

    Li Chen, Zhenzhen Song ... Guoying Zhang
    IL-33 plays an important role in the initiation of labor by leading to stress of the ER via an influx of calcium ions in human uterine smooth muscle cells.

    Self-organization of kinetochore-fibers in human mitotic spindles

    William Conway, Robert Kiewisz ... Daniel J Needleman
    A biophysical model in which kinetochore microtubules nucleate at kinetochores and growth polward along nematic streamlines quantitatively explains kinetochore microtubule lengths, orientations, and spatially varying dynamics in metaphase human spindles.

    trim-21 promotes proteasomal degradation of CED-1 for apoptotic cell clearance in C. elegans

    Lei Yuan, Peiyao Li ... Hui Xiao
    The phagocytic receptor CED-1 is kept at the appropriate level by E3 ligase trim-21-mediated ubiquitination-proteasomal degradation for apoptotic cell clearance, which is independent of retromer-dependent recycling and lysosomal degradation.

    A pulse-chasable reporter processing assay for mammalian autophagic flux with HaloTag

    Willa Wen-You Yim, Hayashi Yamamoto, Noboru Mizushima
    HaloTag becomes resistant to lysosomal proteolysis upon ligand binding, enabling us to measure various types of autophagic flux easily and precisely by using HaloTag-containing reporters for processing assays.
