Description
The transcriptional regulator YAP orchestrates important cell functions, determining tissue homeostasis, organ growth control, and tumorigenesis. Mechanical stimuli are a key input to YAP activity, but the mechanisms controlling this regulation remain largely uncharacterized. We show that CAV1 positively modulates the YAP mechanoresponse to substrate stiffness through actin cytoskeleton-dependent and Hippo kinase-independent mechanisms. RHO activity is necessary but not sufficient for CAV1-dependent mechanoregulation of YAP activity. Systematic quantitative interactomic studies and image-based siRNA screenings provide evidence that this actin-dependent regulation is determined by YAP interaction with the 14-3-3 protein YWHAH. Constitutive YAP activation rescued phenotypes associated with CAV1 loss, including defective ECM remodeling. CAV1-mediated control of YAP activity was validated in vivo in a model of pancreatitis-driven acinar-to-ductal metaplasia. We propose that this CAV1-YAP mechanotransduction system controls a significant share of cell programs linked to these two pivotal regulators, with potentially broad physiological and pathological implications. Overall design: RNA-Seq in WT and Cav1KO mouse embryonic fibroblasts (MEFs) cultured on stiff or soft polyacrylamide hydrogels

Description
Primary human bronchial epithelial cells were transduced with control or hYAP(S127A) lentivirus in sphere forming conditions. Bronchospheres were harvested on day 18-20 for RNAseq analysis Overall design: Passage 1 Primary HBECs from 2 independent donors were transduced with control or hYAP lentivirus. 48 hours post infection, cells were plated on transwell inserts in a 50-50 mixture of ALI medium-Cultrex BME reduced growth factor (RGF) to form spheres. Well differentiated bronchospheres were harvested for RNA-seq analysis on day 18-20 by combining 3 wells of each group for each donor.

ShhCre;Mst1/2flx/flx (Mst1/2 D/D) mice were generated to conditionally delete Mst1 and Mst2 from epithelial progenitors during lung morphogenesis. Lungs from E18.5 control and Mst1/2 D/D mice were mechanically and enzymatically dissociated to generate single cell suspension. Epcam(+) cells were isolated using magnetic microbeads.

Description
Mst1 and Mst2 were conditionally deleted from non-ciliated bronchiolar epithelial cells in the mature lung. Bronchiolar epithelial cells from control and Mst1/2 deleted mice were isolated by cell sorting and used for RNA-seq analysis. Overall design: Scgb1a1-rtTA/tetO-Cre/Mst1;2-flx/flx (Mst1/2 D/D) mice were generated to conditionally delete Mst1 and Mst2 from non-ciliated, secretory bronchiolar epithelial cells. Adult mice were maintained on doxycycline food for 16 days to induce deletion of Mst1/2. Lin-/CD326+/CD24-intermediate cells were isolated by fluorescence cell sorting to enrich for the targeted airway epithelial cells. mRNA isolated from Lin-/CD326+/CD24-intermediate cells from control and Mst1/2 D/D mice was pooled and analyzed by RNA-seq to identify transcriptional changes following deletion of Mst1 and Mst2 from mature lung bronchiolar epithelial cells.

Description
Idiopathic pulmonary fibrosis (IPF) is a lethal interstitial lung disease causing alveolar remodeling, inflammation, and fibrosis. We utilized single cell RNA-sequencing (scRNA-Seq) to identify epithelial cell types and associated biological processes involved in the pathogenesis of IPF. Transcriptomic analysis of epithelial cells from normal human lung defined gene expression patterns associated with highly differentiated alveolar type 2 (AT2) cells, indicated by enrichment of RNAs critical for surfactant homeostasis. In contrast, scRNA-seq of IPF cells identified three distinct subsets of epithelial cell types with characteristics of conducting airway basal and goblet cells and, an additional atypical "transitional" cell that contribute to pathological processes in IPF. Individual IPF cells frequently co-expressed alveolar AT1, AT2, and conducting airway selective markers, demonstrating "indeterminate" states of differentiation not seen in normal lung development. Pathway analysis predicted aberrant activation of canonical signaling via TGF-ß, HIPPO/YAP, P53, and AKT-PI3 Kinase. Immunofluorescence confocal microscopy identified the disruption of alveolar structure and loss of the normal proximal-peripheral differentiation of pulmonary epithelial cells. Single cell transcriptomic analyses of respiratory epithelial cells identified loss of normal epithelial cell identities and unique contributions of epithelial cells to the pathogenesis of IPF. Present scRNA-seq transcriptomic analysis of normal and IPF respiratory epithelial cells provides a rich data source to further explore lung health and disease. Overall design: Dissociated single-cell preparations from peripheral lung of IPF patients (n = 3) and controls (n = 3) from cohort 2 were enriched for AT2 epithelial cells by FACS for CD326 (CD326) double positive, CD45 (hematopoietic) negative, CD31 (endothelial) negative cells, and HTII-280 after dissociation by proteases.

Description
Progressive tissue fibrosis is a major cause of morbidity, and idiopathic pulmonary fibrosis (IPF) is a terminal illness characterized by unremitting matrix deposition in the lung with very limited choice of therapies. The imcomplete understanding of the mechanisms of progressive fibrosis curbs the progress in therapeutics development. Of which, the origin of fibrotic fibroblasts has been poorly defined during the pathogenesis of tissue fibrosis. Here, we fate-mapped a early embryonic transcription factor T-box gene 4 (Tbx4)-derived mesenchymal progenitors in injured adult lung and found that Tbx4+ lineage cells are the major source of myofibroblasts. The ablation of Tbx4+ cells or disruption of Tbx4 signaling attenuated lung fibrosis in bleomycin injury model in mice in vivo. Furthermore, Tbx4+ fibroblasts are more invasive and the regulation of fibroblast invasiveness by Tbx4 is through mediating hyaluronan synthase 2 (HAS2). This study identified a major mesenchymal transcription factor driving the development of fibrotic fibroblasts during lung fibrosis. Understanding the origin, signaling, and functions of these fibroblasts would prove pivotal in the development of therapeutics for patients with progressive fibrotic diseases.
