    A sphingolipid-dependent diffusion barrier confines ER stress to the yeast mother cell

    Lori Clay et al.
    Sphingolipids govern the compartmentalization of yeast cells through the assembly of lateral diffusion barriers in ER membranes.

    Linking glycemic dysregulation in diabetes to symptoms, comorbidities, and genetics through EHR data mining

    Isa Kristina Kirk et al.
    Text mining of complete EHRs for 14,017 diabetes patients and subsequent clustering led to phenotypically deep clusters, showing distinct glycemic profiles, comorbidities, and SNP association patterns.

    Mitochondria supply ATP to the ER through a mechanism antagonized by cytosolic Ca2+

    Jing Yong et al.
    ATP enters the endoplasmic reticulum (ER) lumen through an SLC35B1/AXER-dependentCaATiER mechanism, and ATP usage in the ER renders 'anti-Warburg' effect by increasing ATP regeneration from OxPhos while decreasing glycolysis.

    Shaping of inner ear sensory organs through antagonistic interactions between Notch signalling and Lmx1a

    Zoe F Mann et al.
    A dynamic confrontation between Notch signalling and the transcription factor Lmx1a at the borders of the developing inner ear sensory patches regulates their segregation and the positioning of their boundaries.

    Lamellar projections in the endolymphatic sac act as a relief valve to regulate inner ear pressure

    Ian A Swinburne et al.
    The pressure of fluid in the inner ear is controlled by opening of cellular valves in the endolymphatic sac to allow for regulated transepithelial fluid flow.

    Generation of inner ear hair cells by direct lineage conversion of primary somatic cells

    Louise Menendez et al.
    Direct reprogramming of somatic cells to an inner ear sensory hair cell-like state provides an experimental platform to identify causes and treatments for hair cell loss and hearing deficits.

    Transient role of the middle ear as a lower jaw support across mammals

    Neal Anthwal et al.
    The incus of the middle ear plays a role in supporting the lower jaw prior to the formation of the mammalian jaw joint allowing early feeding in monotremes and marsupials.

    Size control of the inner ear via hydraulic feedback

    Kishore R Mosaliganti et al.
    Size regulation of the otic vesicle, the progenitor of the inner ear, is mediated by mechanical feedback involving fluid influx, hydraulic pressure, and tissue mechanics.

    NHR-14 loss of function couples intestinal iron uptake with innate immunity in C. elegans through PQM-1 signaling

    Malini Rajan et al.
    Nuclear receptor NHR-14 regulates the subcellular localization of the zinc transcription factor PQM-1 to coordinate innate immunity with iron sequestration during pathogen infection in C. elegans..

    Noncanonical binding of BiP ATPase domain to Ire1 and Perk is dissociated by unfolded protein CH1 to initiate ER stress signaling

    Marta Carrara et al.
    The chaperone protein BiP forms complexes with Ire1 and Perk that dissociate when unfolded proteins bind to BiP to activate the unfolded protein response in the ER.
