(Submitter supplied) The capacity of lung tissue to heal without scarring deteriorates with aging. The pulmonary vasculature has emerged as a central regulator of lung repair, and aging-associated endothelial cell dysfunction has been associated with defective lung response to injury and sustained fibrosis. To shed light into aging-associated cellular and transcriptional responses of lung endothelial cells during lung fibrogenesis, we carried out a single cell RNA-seq analysis of bleomycin-treated young (2 months) and aged (72 months) lungs during the early phase of fibrosis resolution (30 days post bleomycin). more...

(Submitter supplied) We identified the transcription factor ETS-related gene (ERG) as a putative orchestrator of lung capillary homeostasis and repair following injury, and whose function was dysregulated in aging. Single-cell RNA-seq of ERG deficient mouse lungs revealed transcriptional abnormalities and fibrogenic features, resembling those associated with aging and IPF, including reduced number of lung progenitor ECs, known as general capillary (gCap) ECs.

(Submitter supplied) In order to elucidate the contribute of the pulmonary vasculature to lung fibrosis, we injured young and aged mice with bleomycine, to create a model of resolving versus persistent lung fibrosis. The animals were sacrificed 30 days after the injury (time point in which we observed a divergent resolving vs persistent lung fibrosis in young vs aged mice). We found that lung fibrosis resolution in young mice was accompained by the activation of transcriptional programs promoting vascular repair and lung fibrosis resolution. more...

(Submitter supplied) Dysfunction of the vascular angiocrine system is critically involved in regenerative defects and fibrosis of injured organs. Previous studies have identified various angiocrine factors and found that risk factors such as aging and metabolic disorders can disturb the vascular angiocrine system in fibrotic organs. One existing key gap is what sense the fibrotic risk to modulate the vascular angiocrine system in organ fibrosis. more...

(Submitter supplied) A hallmark of idiopathic pulmonary fibrosis (IPF) and other interstitial lung diseases is dysregulated repair of the alveolar epithelium. The Hippo pathway effector transcription factors YAP and TAZ are implicated as essential for type 1 and type 2 alveolar epithelial cell (AT1 and AT2) differentiation in the developing lung, yet aberrant activation of YAP/TAZ is a prominent feature of the dysregulated alveolar epithelium in IPF. more...

(Submitter supplied) Fibrotic diseases account for nearly half of all deaths in the developed world. Despite its importance, the pathogenesis of fibrosis remains poorly understood. Recently, the two mechanosensitive transcription cofactors YAP and TAZ have emerged as important profibrotic regulators in multiple murine tissues. Despite this growing recognition, a number of important questions remain unanswered, including which cell types require YAP/TAZ activation for fibrosis to occur and the time course of this activation. more...

(Submitter supplied) In brief, we have applied a novel and unbiased approach to identify distinct and dynamic cell populations, including an in-depth analysis of the fibroblast population, in lung fibrosis. We found that while fibroblast number did not increase after injury, a population of activated fibroblasts can be identified in the fibrotic mouse lung. Using expression profiles of 1,945 lung fibroblasts we redefine the molecular characteristics of activated fibroblasts, finding that they are not a separate population but rather exhibit a similar, yet amplified, gene expression pattern to non-activated cells.

(Submitter supplied) Wildtype mice were given saline or bleomycin by oropharyngeal instillation. After 14 days, during the fibrotic phase of the response, lungs were dissected and total RNA was extracted and used for gene expression profiling. The aim was to identify those genes regulated during the development of fibrosis in this animal model of bleomycin-induced lung fibrosis.

(Submitter supplied) The results of this study indicate that the expression of YAP/TAZ was significantly upregulated in stenotic fibroblasts, which was associated with the YAP/TAZ target gene signature. YAP/TAZ knockdown suppressed the activation of intestinal fibroblasts. In intestinal fibroblasts, YAP/TAZ were activated by the Rho-ROCK1 signalling pathway. High YAP/TAZ expression was positively correlated with ROCK1 expression, which is a prognostic marker for intestinal obstruction in CD patients.

(Submitter supplied) Regenerating new alveolar epithelium is essential for recovery from many lung diseases. This multi-cellular regenerative process occurs when type II alveolar pneumocytes (AT2), with support from mesenchymal niche cells, proliferate to generate more AT2 cells and transdifferentiate in type I pneumocytes. To elucidate how coordinated events between AT2 cells and mesenchyme restore alveolar epithelium we used unbiased genome-wide analysis of chromatin accessibility and gene expression in both cell types following acute lung injury. more...

(Submitter supplied) Pulmonary fibrosis (PF) is a chronic interstitial lung disease that causes irreversible and progressive lung scarring and respiratory failure. Activation of fibroblasts (FBs) play a central role in progression of PF. Here we report that platelet endothelial aggregation receptor 1 (Pear1) in FBs is a new molecular target for PF therapy. Pear1 deficiency spontaneously caused respiratory function decline and alveolar collagens accumulation in old mice. more...

(Submitter supplied) Tissue homeostasis requires lineage fidelity of stem cells. Dysregulation of cell fate specification and differentiation leads to various diseases, yet the cellular and molecular processes remain elusive. We demonstrate that YAP/TAZ activation reprograms airway secretory cells to lose cellular identity and acquire squamous alveolar type 1 (AT1) fate in the lungs. Significantly, this cell fate conversion is mediated via distinctive transitional cell states of Damage-Associated Transient Progenitors (DATPs), recently known to emerge during injury repair, in mouse and human lungs. more...
