    In vivo reprogramming of pancreatic acinar cells to three islet endocrine subtypes

    Weida Li, Mio Nakanishi ... Qiao Zhou
    Combinations of transcription factors can convert pancreatic acinar cells into endocrine α-, β- and δ-cells in vivo.

    Sequential activation of transcriptional repressors promotes progenitor commitment by silencing stem cell identity genes

    Noemi Rives-Quinto, Hideyuki Komori ... Cheng-Yu Lee
    Silencing of stem cell identity genes during progenitor commitment ensures that intermediate progenitors robustly commit to generate differentiated cell types rather than abnormal stem-cell-like cells during indirect neurogenesis.

    Hyperglycemia induced cathepsin L maturation linked to diabetic comorbidities and COVID-19 mortality

    Qiong He, Miao-Miao Zhao ... Jin-Kui Yang
    High glucose levels promote CTSL maturation and translocation from the endoplasmic reticulum to the lysosome via the ER-Golgi-lysosome axis.

    Biallelic TANGO1 mutations cause a novel syndromal disease due to hampered cellular collagen secretion

    Caroline Lekszas, Ombretta Foresti ... Thomas Haaf
    The first human TANGO1-associated syndromal disease manifests as impaired collagen secretion, highlighting the importance of TANGO1 in human pathophysiology.

    Gradients in the biophysical properties of neonatal auditory neurons align with synaptic contact position and the intensity coding map of inner hair cells

    Alexander L Markowitz, Radha Kalluri
    The biophysical diversity that is intrinsic to spiral ganglion neurons emerges as spatial gradients during early post-natal development and endures through subsequent maturation to likely contribute to sound intensity coding.

    GSK3 inhibition rescues growth and telomere dysfunction in dyskeratosis congenita iPSC-derived type II alveolar epithelial cells

    Rafael Jesus Fernandez, Zachary JG Gardner ... F Brad Johnson
    Telomere dysfunction in iPSC-derived type II alveolar epithelial cells causes senescence and gene expression changes including Wnt-related changes that GSK3 inhibition can rescue, providing insight into pulmonary fibrosis pathogenesis.

    Reducing lipid bilayer stress by monounsaturated fatty acids protects renal proximal tubules in diabetes

    Albert Pérez-Martí, Suresh Ramakrishnan ... Matias Simons
    Monounsaturated fatty acids protect against DKD by enhancing membrane fluidity and decreasing ER lipid bilayer stress in renal proximal tubules.

    Murine Fam65b forms ring-like structures at the base of stereocilia critical for mechanosensory hair cell function

    Bo Zhao, Zizhen Wu, Ulrich Müller
    Super-resolution microscopy reveals a highly organized compartment in the stereocilia of mechanosensory hair cells of the inner ear, which is critical for hair cell function and affected in disease.

    Tendon and motor phenotypes in the Crtap-/- mouse model of recessive osteogenesis imperfecta

    Matthew William Grol, Nele A Haelterman ... Brendan H Lee
    Ultrastructural, biochemical, and behavioral assessments reveal that the Crtap-/- mouse model of severe, recessive Osteogenesis Imperfecta presents with defects in tendon structure and strength that correlate with severe motor deficits.
