    Activation of transient receptor potential vanilloid 4 is involved in pressure overload-induced cardiac hypertrophy

    Yan Zou, Miaomiao Zhang ... Bing Han
    Activation of TRPV4 induced increases in Ca2+ influx, activated CaMKII, enhanced pro-inflammatory NFκB-NLRP3 signaling, and promoted inflammation response, thus contributing to pathological cardiac remodeling.

    Endoplasmic reticulum stress activates human IRE1α through reversible assembly of inactive dimers into small oligomers

    Vladislav Belyy, Iratxe Zuazo-Gaztelu ... Peter Walter
    Stress sensors in the membrane of the endoplasmic reticulum respond to the accumulation of unfolded proteins by briefly forming small phosphorylation-competent oligomers and dissolving back into active dimers.

    Live imaging of the co-translational recruitment of XBP1 mRNA to the ER and its processing by diffuse, non-polarized IRE1α

    Silvia Gómez-Puerta, Roberto Ferrero ... Franka Voigt
    Development of a live single-molecule imaging approach to visualize XBP1 mRNAs, which are recruited for translation on the ER and efficiently spliced in the absence of large IRE1α foci.

    MAF1, a repressor of RNA polymerase III-dependent transcription, regulates bone mass

    Ellen Phillips, Naseer Ahmad ... Deborah L Johnson
    Identification of a novel role for the transcriptional repressor, MAF1, and RNA polymerase III-dependent transcription, in osteoblast differentiation, mineralization, and bone biology.

    On demand expression control of endogenous genes with DExCon, DExogron and LUXon reveals differential dynamics of Rab11 family members

    Jakub Gemperle, Thomas S Harrison ... Patrick T Caswell
    DExCon, LUXon, and DExogron approaches simultaneously block endogenous gene expression and permit tuning of re-expression levels in time and space; proof-of-principle reveals unforeseen differences in protein kinetics, cargo handling, and cell migration regulation between closely related Rab11 family members.

    Intrinsic excitability mechanisms of neuronal ensemble formation

    Tzitzitlini Alejandre-García, Samuel Kim ... Rafael Yuste
    Optogenetic and electrical stimulation of primary visual cortex neurons reveals synaptic and cell-intrinsic mechanisms that underlie neuronal ensemble formation.

    DNA-damage induced cell death in yap1;wwtr1 mutant epidermal basal cells

    Jason KH Lai, Pearlyn JY Toh ... Timothy E Saunders
    Substrate rigidity modulates genomic stress in the epidermal basal cells of the developing zebrafish embryo and Yap1 and Wwtr1 are required for its survival.

    Endocytic trafficking promotes vacuolar enlargements for fast cell expansion rates in plants

    Kai Dünser, Maria Schöller ... Jürgen Kleine-Vehn
    Cellular and vacuolar size expansion are coordinated.

    Inhibition of the sodium-dependent HCO3- transporter SLC4A4, produces a cystic fibrosis-like airway disease phenotype

    Vinciane Saint-Criq, Anita Guequén ... Carlos A Flores
    The reduction of bicarbonate secretion into the airways reproduces cystic fibrosis-like features, independently of chloride secretion.

    Subtype-specific responses of hKv7.4 and hKv7.5 channels to polyunsaturated fatty acids reveal an unconventional modulatory site and mechanism

    Damon JA Frampton, Koushik Choudhury ... Sara I Liin
    Polyunsaturated fatty acids facilitate or impede Kv7 channel activation, depending on channel subtype and their dominant functional site(s).
