Why different species are predisposed to different tumor spectra is not well understood. In particular, whether the physical location of tumor suppressor genes relative to one another influences tumor predisposition is unknown. Renal cancer presents a unique opportunity to explore this question. Renal cell carcinoma (RCC) of clear-cell type (ccRCC), the most common type, begins with an intragen...

PURPOSE von Hippel-Lindau (VHL) disease is a dominantly inherited, multisystemic tumor syndrome caused by mutations in the VHL gene. This study was conducted to establish genotype-phenotype correlations between the positions of disease-causing missense mutations and the ocular phenotypes of VHL disease. METHODS Participants with clinically defined VHL disease and documented germline missense ...

Hypoxic signaling is a central modulator of cellular physiology in cancer. Core members of oxygen-sensing pathway including the von Hippel-Lindau tumor suppressor protein (pVHL) and the hypoxia inducible factor (HIF) transcription factors have been intensively studied, but improved organismal models might speed advances for both pathobiologic understanding and therapeutic modulation. To study H...

The von Hippel-Lindau (VHL) tumor suppressor gene regulates extracellular matrix deposition. In VHL negative renal cancer cells, VHL(-), the lack of fibronectin matrix assembly is thought to promote and maintain tumor angiogenesis allowing vessels to infiltrate tumors. Therefore, and considering the importance of this process in tumor growth, we aimed to study why VHL(-) renal cancer cells fail...

von Hippel-Lindau (VHL) tumor suppressor protein-inactivated in VHL disease and sporadic kidney cancer-is a component of an E3 ubiquitin ligase complex that selectively ubiquitinates the alpha subunit of the hypoxia-inducible factor (HIF) transcription factor for subsequent destruction by the 26S proteasome. Here, we report the identification and characterization of the first VHL homologue, VHL...

OBJECTIVE We studied the reciprocal effect of pregnancy and von Hippel-Lindau (VHL) disease by analyzing the influence of pregnancy on VHL disease-related lesions and VHL disease on pregnancy outcome. METHODS Medical charts and imaging reports from the VHL disease expertise centers in the Netherlands were used to retrospectively assess lesion progression score before and after pregnancy and t...

Hypoxia-inducible factor (HIF)-1α and HIF-2α play an important role in liver fibrosis. von Hippel-Lindau protein (VHL), a key mediator of HIF-α, regulates fibrosis in an organ- and cell-specific way. In this study, human liver samples were collected from hepatitis C-, alcoholic-, and cholestatic-associated fibrotic and healthy individuals. Two mouse models of liver fibrosis were established: bi...

During the last decade the knowledge about the molecular mechanisms of the cellular adaption to hypoxia and the function of the "von Hippel Lindau" (VHL) protein in renal cell carcinoma (RCC) has increased, but there exists little information about the overlap and differences in gene/protein expression of both processes. Therefore the aim of this study was to dissect VHL- and hypoxia-regulated ...

Von Hippel-Lindau (VHL) syndrome is characterized by hemangioblastomas of the brain, spinal cord, and retina, renal cysts, clear cell renal cell carcinoma, and pheochromocytoma. VHL is caused by mutations in the VHL tumor suppressor gene. We attempted to detect mutation in the VHL gene in a 5-generation Chinese family with VHL. We identified a novel small duplication that altered the reading fr...
