Project description:Effect of fumarase point mutation or knock-out on transcriptional profile in yeast to model hereditary leiomyomatosis and renal cell cancer (HLRCC).
Project description:Fumarate hydratase (FH) mutations cause hereditary leiomyomatosis and renal cell cancer (HLRCC). We have conditionally inactivated the murine ortholog (Fh1) in renal tubular epithelial cells in order to generate an in vivo model of HLRCC. Fh1 knockout mice recapitulates important aspects of HLRCC including the development of renal cysts that overexpress hypoxia inducible factor alpha (Hifa) and Hif-target genes. We used microarrays to detail the global programme of gene expression underlying cyst development in Fh1 knockout mice and identified distinct classes of up-regulated genes during this process. Keywords: gene expression, comparison (wild-type n=3 vs knockout n=3)
Project description:Gene expression profiles of normal kidney (3 technical replicates) and a renal tumor (3 technical replicates) from a hereditary leiomyomatosis and renal cell cancer (HLRCC) patient carrying a germline mutation in the fumarate hydratase (FH) gene.

Keywords: gene expression, comparison (wild-type n=3 vs knockout n=3) Renal epithelial tissue was macro-dissected from Fh1 knockout mice and sex-matched litter mate control disease-free animals for RNA extraction and hybridization on Affymetrix microarrays.
Project description:Gene expression profiles of normal kidney (3 technical replicates) and a renal tumor (3 technical replicates) from a hereditary leiomyomatosis and renal cell cancer (HLRCC) patient carrying a germline mutation in the fumarate hydratase (FH) gene. Tumor and normal tissue from one patient, both in 3 techincal replicates.
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:Fumarate hydratase (FH) is the enzyme in the Krebs cycle, which transforms fumarate to malate. Loss of fumarate hyrdragase leads to hereditary leiomyomatosis and renal cell cancer (HLRCC). The biallelic inactivation has been highly accumulated in FH-deficient cells and is considered a major pro-oncogenic factor for HLRCC tumorigenesis. We used microarrays to understand the global readaptation of cell metabolism of gene expression underlying the truncated Krebs cycle by loss of function of fumarate hydratase.
