Gene expression analysis in primary human renal tumors, categorized by VHL genotype and HIF-alpha expression

Human renal cell carcinomas (RCC) have differential expression of HIF-1alpha and HIF-2alpha, depending on VHL genotype and other events. Here, we have divided a series of RCC samples for HIF-alpha expression and VHL genotype, in order to define differentially expressed genes Keywords: Patient Sample Study A total of 57 frozen RCC samples were stained for HIF-1alpha and HIF-2alpha, and genotyped for VHL. 5 VHL WT/HIF-negative, 8 VHL-deficient/HIF-1alpha+/HIF-2alpha+ and 8 VHL-deficient/HIF-2alpha+ tumors were selected for microarray
