Project description:We show that knock-in mutations of the nuclear corepressor SMRT in C57Bl6 mice (SMRTmRID) produces a novel respiratory distress syndrome (RDS) due to prematurity of the type I pneumocyte. Treatment with the anti-thyroid hormone drug, propylthiouracil (PTU), completely rescues the SMRT-induced RDS, suggesting an unrecognized and essential role for the thyroid hormone receptor (TR) in lung development. We show that TR and SMRT control type I pneumocyte differentiation through Klf2, which in turn appears to directly activate the type I pneumocyte gene program. Conversely, mice without lung Klf2 lack mature type I pneumocytes and die shortly after birth, closely recapitulating the SMRTmRID phenotype. These results identify a second nuclear receptor, the TR, in type I pneumocyte differentiation and suggest a new type of therapeutic option in the treatment of glucocorticoid non-responsive RDS. Total RNA was obtained from WT and SMRT-RID E18.5 lungs of embryos from mothers treated with Diet containing 0.15% PTU or control chow for 2 days (from E16.5).

Project description:The disease caused by the novel coronavirus of 2019 (COVID-19) has resulted in significant morbidity and mortality world-wide. A systemic hyper-inflammation characterizes the severe COVID-19 disease often associated with acute respiratory distress syndrome (ARDS). Bloodbiomarkers with prognostic relevance are of great importance in effective triage and critical care of severe COVID-19 patients. In the present study we report higher plasma abundance of soluble urokinase-type plasminogen activator receptor (sUPAR), shown to be expressed by an abnormally expanded circulating myeloid cell population, in severe COVID-19 patients with acute respiratory distress syndrome. SUPAR level was found to be linked to a characteristic proteomic signature of plasma. A receiver operator characteristics curve analysis identified a cut-off value of sUPAR at 2000pg/ml, which was linked to characteristic differential expression in the immune transcriptome as well as clinical outcomes in our patient cohort. Thus we identified sUPAR as a biomarker with strong predictive potential for clinical outcomes in severe COVID-19.

Project description:SMRT (silencing mediator of retinoid and thyroid hormone receptors) is recruited by numerous transcription factors to mediate lineage and signal dependent transcriptional repression. We generated a knock-in mutation in the receptor interaction domain (RID) of SMRT (SMRTmRID) that solely disrupts its interaction with nuclear hormone receptors. SMRTmRID-derived 3T3-MEFs display a dramatically increased adipogenic capacity and accelerated differentiation rate. We measured global gene expression in wild-type versus SMRTmRID-derived 3T3-MEFs in the undifferentiated state to examine which pathways were altered. Our results demonstrate that SMRT-RID dependent repression is a key determinant of the adipogenic set point. Experiment Overall Design: 3T3 cells derived from wild-type and SMRT RID MEFs were cultured under pre-differentiated conditions prior to harvesting for RNA.

Project description:Pulmonary surfactant (PS) produced by alveolar type II (ATII) cells is necessary in maintaining normal lung function, and a decrease or change in composition of PS is the main cause of alveolar collapse in acute respiratory distress syndrome (ARDS). But the mechanism of decrease or com-position change of PS is still unknown.
