Project description:p73 is a p53 family transcription factor that plays critical roles during development and tumor suppression. We analyzed p73 activity using a combination of ChIP-on-Chip and gene expression profiling, both at baseline and after treatment with the mTOR inhibitor rapamycin. We generated an mTOR-p73 gene signature that predicts rhabdomyosarcoma tumor subtype and patient outcome, and is enriched for p73 target genes involved in mesenchymal stem cell differentiation and tumorigenesis. Rh30 rhabdomyosarcoma cells were infected with lentivirus (either control or expressing one of two RNAi constructs targeting p73) for 3 d, and treated with vehicle or 40 nM rapamycin for 24 h, and then total RNA was harvested. Experiments were performed in duplicate for a total of 8 samples. For p73 RNAi, a different targeting construct was used for each replicate.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
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.
