Genetic Analysis of Pathways Regulated by the von Hippel-Lindau Tumor Suppressor in Caenorhabditis elegans

Project description:The von Hippel-Lindau (VHL) tumor suppressor functions as a ubiquitin ligase that mediates proteolytic inactivation of hydroxylated a subunits of hypoxia-inducible factor (HIF). Although studies of VHL defective renal carcinoma cells suggest the existence of other VHL tumor suppressor pathways, dysregulation of the HIF transcriptional cascade has extensive effects that make it difficult to distinguish whether, and to what extent, observed abnormalities in these cells represent effects on pathways that are distinct from HIF. Here, we report on a genetic analysis of HIF dependent and independent effects of VHL inactivation by studying gene expression patterns in C. elegans. We show tight conservation of the HIF-1/VHL-1/EGL-9 hydroxylase pathway. However, persisting differential gene expression in hif-1 versus hif-1; vhl-1 double mutant worms clearly distinguished HIF-1 independent effects of VHL-1 inactivation. Genomic clustering, predicted functional similarities, and a common pattern of dysregulation in both vhl-1 worms and a set of mutants (dpy-18, let-268, gon-1, mig-17 and unc-6), with different defects in extracellular matrix formation, suggest that dysregulation of these genes reflects a discrete HIF-1 independent function of VHL-1 that is connected with extracellular matrix function.

Transcription profiling of liver from mice with constitutively active Hypoxia Inducible Factor (HIF-1a and HIF-2a) or inactivated von Hippel-Lindau tumor suppressor gene product (pVHL)

Project description:The effects of constitutively active Hypoxia Inducible Factor (HIF) and inactivated von Hippel-Lindau tumor suppressor gene product (pVHL) were examined in a mouse model. Conditionally expressed, constitutively active HIF-1a and HIF-2a were compared with inactivated pVHL.

Transcription profiling of pancreatic islet cells in wild type and von Hippel-Lindau tumor suppressor knock-out mice

Project description:Understanding the nature of the various glucose-derived signals for insulin secretion (both triggering and amplifying) is essential for gaining insight into the functional failure of the beta-cells in diabetes and the development of drugs for correcting this problem. The beta-cells uniquely couple changes in cellular metabolism to electrical activity and thus insulin release. In mice, beta-cell specific deletion of the von Hippel-Lindau (VHL) tumor suppressor protein leads to the activation of a HIF transcription program that includes genes involved in glycolysis, suppression of mitochondrial activity and lactate production. This reprogramming of cellular metabolism results in abnormal insulin secretion properties. Experiment Overall Design: Three batches of isolated islets from each genotype where used for RNA isolation and Affymetrix measurements.

Effect of deletion of von-Hippel-Lindau (VHL) in the proximal tubule in diabetic kidney disease

Project description:To establish the role of proximal tubular hypoxia in diabetic kidney disease, we use a mouse line with a specific deletion of von-Hippel-Lindau (VHL) in the proximal tubule and treat them with streptozotocin (STZ) to induce a type I diabetes mellitus. 10 weeks after induction of diabetes mellitus samples were collected.

Zebrafish von Hippel-Lindau (vhl) tumor suppressor mutants compared to siblings at 7 dpf

Project description:We have generated two zebrafish lines carrying inactivating germline mutations in the von Hippel-Lindau (VHL) tumor suppressor gene ortholog vhl. Mutant embryos display a general systemic hypoxic response, including the upregulation of hypoxia-induced genes by 1 day post-fertilization and a severe hyperventilation and cardiophysiological response. vhl mutants develop polycythemia with concomitantly increased epo/epor mRNA levels and Epo signaling. In situ hybridizations reveal global up-regulation of both red and white hematopoietic lineages. Hematopoietic tissues are highly proliferative, with enlarged populations of c-myb+ HSCs and circulating erythroid precursors. Chemical activation of Hif-signaling recapitulated aspects of the vhl-/- phenotype. Furthermore, microarray expression analysis confirms the hypoxic response and hematopoietic phenotype observed in vhl-/- embryos. We conclude that Vhl participates in regulating hematopoiesis and erythroid differentiation. Injections with human VHLp30 and R200W mutant mRNA demonstrate functional conservation of VHL between mammals and zebrafish at the amino acid level, indicating that vhl mutants are a powerful new tool to study genotype-phenotype correlations in human disease. Zebrafish mutants are the first congenital embryonic viable systemic vertebrate animal model for VHL, representing the most accurate model for VHL-associated polycythemia to date. They will contribute to our understanding of hypoxic signaling, hematopoiesis and VHL-associated disease progression.

RNA expression data from kidneys lacking von Hippel-Lindau (VHL) protein in tubular epithelial cells

Project description:The cellular response to low oxygen supply is mediated by hypoxia-inducible factors (HIF). Under hypoxic conditions, HIF is stabilized and target genes are induced. Under normoxia, however, HIF is ubiquitinated through the von Hippel-Lindau protein (VHL), which results in proteasomal degradation. HIF activation leads to induction of genes involved in erythropoiesis, angiogenesis, and cell survival. Furthermore, HIF orchestrates a metabolic shift from oxidative phosphorylation to glycolysis to facilitate ATP production under low oxygen conditions. We used microarrays to detail gene expression changes in kidneys with stable HIF activation in renal tubules, which was achieved by tubule-specific VHL ablation.
