The von Hippel-Lindau tumor suppressor gene (VHL) is mutated in clear cell renal cell carcinomas (RCC), leading to the activation of hypoxia-inducible factor (HIF)-mediated gene transcription.
Elevated number of circulating EPCs seems to be related to high EPO production from RCC with novel double somatic mutation of the VHL gene in this patient.
We concluded that a strong expression of PTEN in renal cell cancer did not block the PI3K-mediated phosphorylation of Akt in the tumour specimens analysed.
Finally, immunohistochemical staining of Cyr61/CCN1 and CTGF/CCN2 in RCC tissue samples showed that increased expression of these proteins correlates with the loss of VHL protein expression.
It is of great interest to know whether RCCs occurring in the dialytic kidneys harbour the same or similar mutations of the von Hippel-Lindau (VHL) gene as conventional dialysis-unrelated clear cell RCCs so often do.
The purpose of this study was to determine the existence of vhl gene mutations in renal tumour tissue among patients with sporadic RCC and to assess the effects on the structure of the VHL protein.
Loss of expression of von Hippel-Lindau tumor suppressor protein associated with improved survival in patients with early-stage clear cell renal cell carcinoma.
Effect of radiation and ibuprofen on normoxic renal carcinoma cells overexpressing hypoxia-inducible factors by loss of von Hippel-Lindau tumor suppressor gene function.
The von Hippel-Lindau tumor suppressor gene (VHL), which resides on chromosome 3p25, is mutated or silenced in >50% of sporadic clear cell renal cell carcinomas.
