Project description:Nuclear factor of activated T cells 5 (NFAT5) and cyclooxygenase 2 (COX2; PTGS2) both participate in diverse pathologies including cancer progression. However, the biological role of the NFAT5-COX2 signaling pathway in human endometrial cancer has remained elusive. The present study explored whether NFAT5 is expressed in endometrial tumors and if NFAT5 participates in cancer progression. To gain insights into the underlying mechanisms, NFAT5 protein abundance in endometrial cancer tissue was visualized by immunohistochemistry and endometrial cancer cells (Ishikawa and HEC1a) were transfected with NFAT5 or with an empty plasmid. As a result, NFAT5 expression is more abundant in high-grade than in low-grade endometrial cancer tissue. RNA sequencing analysis of NFAT5 overexpression in Ishikawa cells upregulated 37 genes and downregulated 20 genes. Genes affected included cyclooxygenase 2 and hypoxia inducible factor 1α (HIF1A). NFAT5 transfection and/or treatment with HIF-1α stabilizer exerted a strong stimulating effect on HIF-1α promoter activity as well as COX2 expression level and prostaglandin E2 receptor (PGE2) levels. Our findings suggest that activation of NFAT5-HIF-1α-COX2 axis could promote endometrial cancer progression.

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:Temozolomide (TMZ) therapy offers minimal clinical benefits in patients with glioblastoma multiforme (GBM) with high EGFR activity, underscoring the need for effective combination therapy. Here, we show that tonicity-responsive enhancer binding protein (NFAT5) lysine methylation, is a determinant of TMZ response. Mechanistically, EGFR activation induces phosphorylated EZH2 (Ser21) binds and triggers NFAT5 methylation at K668. Methylation prevents NFAT5 cytoplasm interaction with E3 ligase TRAF6, thus blocks TRAF6 induced K63-linked ubiquitination mediated NFAT5 lysosomal degradation and cytosol localization restriction, result in NFAT5 protein stabilization, nuclear accumulation and activation. Methylated NFAT5 leads to the upregulation of MGMT, a transcriptional target of NFAT5, which is responsible for unfavorable TMZ response. Inhibition of NFAT5 K668 methylation improved TMZ efficacy in orthotopic xenografts and PDX models. Notably, NFAT5 K668 methylation levels are elevated in TMZ-refractory specimens and confer poor prognosis. Our findings suggest targeting NFAT5 methylation as an effective therapeutic strategy to improve TMZ response in tumors with EGFR activation.
