Project description:Chronic hypoxia causes detrimental structural alterations in the lung, which are partially dependent on stress responses of the endothelium. In this context, we revealed that hypoxia-exposed murine lung endothelial cells (MLEC) activate nuclear factor of activated T-cells 5 (NFAT5/TonEBP) - a transcription factor that adjusts the cellular transcriptome to cope with multiple environmental stressors. Here, we studied the impact of NFAT5 on hypoxia-induced gene expression in MLEC by comparing the transcriptome of control and Nfat5-deficient MLEC, which were isolated from mouse lungs after exposure to normoxia and hypoxia for 7 days and processed for scRNA seq.

Project description:NFAT5 is an osmoprotective transcription factor whose DNA binding domain shares structural homology with NFkappaB and other member of NFAT family, but its role in chronic inflammatory diseases remains unclear. The mRNA profiling of synoviocytes and endothelial cells transfected with NFAT5-targeted siRNA reveals three major changes in cellular processes associated with the pathogenesis of rheumatoid arthritis: cell cycle and survival, angiogenesis, and cell migration. The cells were transfected with NFAT5-targeted siRNA or non-specific scrambled (control) siRNA.

Project description:The skin protects the human body against dehydration and harmful challenges. Keratinocytes (KCs) are the most frequent epidermal cells, and it is anticipated that KC-mediated transport of Na+ ions creates a physiological barrier of high osmolality against the external environment. We studied in KCs the role of NFAT5, a transcription factor whose activity is controlled by osmotic stress. Cultured KCs from adult mice secrete more than 300 proteins, and upon NFAT5 ablation, the secretion of several matrix proteinases, including metalloproteinase-3 (Mmp3) and kallikrein-related peptidase 7 (Klk7), was markedly enhanced. An increase in Mmp3 and Klk7 RNA levels was also detected in transcriptomes of Nfat5-/- KCs, along with increases of numerous components of ‘Epidermal Differentiation Complex’ (EDC), as proline-rich Sprr and S100 proteins. NFAT5 and Mmp3 are co-expressed in basal KCs from fetal and adult skin but not in skin of newborn mice. This is correlated with a strong increase in Mmp3 and Klk7 expression in KCs of newborn mice and suggests, along with the fragile epidermis of adult Nfat5-/- mice, a suppressive effect of NFAT5 on the expression of matrix proteases in skin. Our data suggest that NFAT5 controls the expression of matrix proteases in skin and contributes to the many fold changes during embryonal skin development and skin integrity in adults.

Project description:Chronic hypoxic stress stimulates lung endothelial cells to promote vascular remodeling processes, which - in the long run - increase the resistance of pulmonary arteries. While several molecular determinants promoting these maladaptive changes have been delineated, their transcriptional regulation is not well studied. In this context, we revealed that hypoxia activates nuclear factor of activated T-cells 5 (NFAT5/TonEBP) in murine lung endothelial cells (MLECs) - a transcription factor that regulates the adjustment of the cellular transcriptome to cope with osmotic, biomechanical or metabolic environmental stressors. Here, we studied the functional relevance of NFAT5 for the control of endothelial hypoxic stress responses in the lung. Genetic ablation of Nfat5 in endothelial cells did not evoke any obvious phenotypic alterations under normoxia. However, microarray-based transcriptome analyses of lung tissue revealed significant alterations 7 but not 21 days after exposure to normobaric hypoxia (10% O2).

Project description:Tonicity-Responsive Enhancer-Binding Protein (NFAT5), also known as Tonicity-Responsive Enhancer Binding Protein (TonEBP), is a important transcription factor in the regulation of osmoprotective and inflammatory genes. NFAT5 has been reported to regulate the pathological processes of inflammatory and autoimmune disorders. Our data provides a insight to the gene expression in NFAT5 deficiency BV2 microglia cells, which NFAT5 knocked down by sh-RNA.
