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:microRNAs are small (22-24 nucleotide), non-coding RNA transcripts that play a role in RNA silencing and post transcriptional regulation of gene expression. They have been implicated to have profound roles in many cancers. The role of microRNAs in chondrosarcoma progression is not well understood. Our lab has identified miR-181a to be up-regulated in chondrosarcoma. miR-181a modulates CXCR4 signaling by targeting RGS-16, leading to increased levels of VEGF and MMP-1, major factors in tumor invasion. In an effort to identify other targets of miR-181a apart from RGS-16, we carried out a gene array to compare gene expression between untreated/control CS-1(chondrosarcoma cell line) cells and CS-1 cells transduced with a lenti virus expression construct with anti-miR-181a sequence.
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.
