Project description:Asthma is a chronic inflammatory airway disease characterized by airway inflammation and remodeling. The role of 15-oxo-5Z,8Z,11Z,13E-eicosatetraenoic acid (15-oxoETE), a 15-HETE metabolite catalyzed by 15-prostaglandin dehydrogenase (15-PGDH), has been relatively unexplored in asthma. In this study, we used RNA-seq to explore the effect of 15-KETE on the transcriptome of airway epithelial cells, aiming to identify its potential downstream targets and mechanisms of action.

Project description:To investigate the detailed molecular mechanisms for the regulatory role of HIF-1α in colon, microarray gene expression analysis was performed on colon RNA isolated from 6- to 8-week-old Hif-1α+/+, Hif-1αLSL/LSL mice. Background & Aims: The progression and growth of solid tumors leads to a state where tumors outgrow their capacity for efficient oxygenation and nutrient uptake and an increase in tumor hypoxia. Tumor hypoxic response is mediated by hypoxia-inducible factor (HIF)-1a and HIF-2a. These transcription factors regulate a battery of genes that are critical for tumor oxygenation, tumor metabolism, and cell proliferation and survival. Therefore, inhibitors of HIF have been sought for as anti-neoplastic agents in several different kinds of cancers. Interestingly, in ischemic and inflammatory diseases of the intestine, activation of HIF-1a is beneficial, and can reduce intestinal inflammation. The efficacy of pharmacological agents that chronically activate HIF-1a are decreased due to the tumorigenic potential of HIF. However, recent advance in understanding HIF signaling have identified mechanisms, which could allow for isoform specific activators. Activation of HIF-2a increases colon carcinogenesis and progression in mouse models. However, the role of chronic HIF-1a activation is unclear in the progression in colon cancer. The present data demonstrates that activation of HIF-1a in epithelial cells does not increase colon carcinogens or progression in two mouse models of colon cancer, and provides the proof of principle that HIF-1a activation maybe safe as therapies for inflammatory bowel disease. Global gene expression profiling in colon RNAs isolated from 6- to 8-week-old Hif-1α+/+ (n=5, Shah 019) and Hif-1αLSL/LSL (n=5, Shah 020).

Project description:Mitochondria fulfill vital metabolic functions and act as crucial cellular signaling hubs integrating their metabolic status into the cellular context. Here, we show that defective cardiolipin-remodeling, upon loss of the cardiolipin acyl transferase Tafazzin, mutes HIF-1a signaling in hypoxia. Tafazzin-deficiency does not affect posttranslational HIF-1a regulation but rather HIF-1a gene-expression, a dysfunction recapitulated in iPSCs-derived cardiomyocytes from Barth Syndrome patients with Tafazzin-deficiency. RNAseq analyses confirmed drastically altered signaling in Tafazzin mutant cells. In hypoxia, Tafazzin-deficient cells display reduced production of reactive oxygen species (ROS) perturbing NF-kB activation and concomitantly HIF-1a gene-expression. In agreement, Tafazzin-deficient mice hearts display reduced HIF-1a levels and undergo maladaptive hypertrophy with heart failure in response to pressure overload challenge. We conclude that defective mitochondrial cardiolipin-remodeling dampens HIF-1a signaling through inactivation of a non-canonical signaling pathway: Lack of NF-kB activation through reduced mitochondrial ROS production diminishes HIF-1a transcription.
