  • Title: Molecular biology of renal cell carcinoma.
    Author: Mellado B, Gascón P.
    Journal: Clin Transl Oncol; 2006 Oct; 8(10):706-10. PubMed ID: 17074668.
    Abstract:
    Recent developments in molecular biology have lead to an increased understanding of the events involved in renal cell carcinoma (RCC) carcinogenesis. In this field, basic molecular pathways important to oncogenic transformation secondary to Von Hippel-Lindau (VHL) tumor suppression gene inactivation, associated to clear-cell RCC, have been elucidated. Loss of function of VHL results in the high-expression of pro-angiogenic growth factors, such as vascular endothelial growth factor (VEGF) and platelet derived growth factor (PDGF). New therapies against specific targets in RCC have demonstrated significant clinical activity in patients. These therapeutic approaches are based on the VEGF inhibition by using anti-VEGF monoclonal antibodies (bevacizumab) or multi-kinase inhibitors, that also target PDGF and c-kit tyrosine kinases (sorafenib, sunitinib); or by the inhibition of the mammalian target of rapamycin (mTOR) pathway (temsirolimus). This article reviews current knowledge of molecular pathogenesis of inherited and sporadic RCC.
