Somatic mutations or loss of expression of tumor suppressor VHL happen in the vast majority of clear cell Renal Cell Carcinoma, and it's causal for kidney cancer development.
Clear cell renal cell carcinoma (ccRCC) is the major subtype of kidney cancer that is characterized by frequent inactivation of the von Hippel-Lindau (VHL) gene in 80-90% of the tumors.
Loss of VHL function causes the overexpression of transforming growth factor (TGF)-alpha, leading us to hypothesize that TGF-alpha could be a potential TAA for immunotherapy of kidney cancer, which was evaluated in this study.
However, the low frequency of biallelic inactivation suggests that either PTEN/MMAC1 is inactivated by other mechanisms or it is not the only target of chromosome 10q deletion in primary bladder and renal cell cancer.
We provided novel structural and functional information on the expression of the IL-2 receptor in kidney cancer cells and in other normal and neoplastic human epithelial tissues.
Statistical analyses showed that grade, vascular invasion, and necrosis in bladder cancer, a high Gleason score in prostate cancer, and the 1-year mortality rate in renal cancer were significantly related with p53 nuclear overexpression (P < 0.05).
The c-met receptor is present in specific tubular segments in the normal kidney and is frequently expressed in higher nuclear grade renal cancers, suggesting a role in renal carcinoma progression.
ABCB1 and ABCC2 mRNA and protein expression levels were determined by real-time polymerase chain reaction or immunohistochemistry in kidney cancer and adjacent unaffected cortex tissue of 82 nephrectomized renal cell cancer (RCC) patients (63 clear-cell RCC (CCRCC), 19 non-CCRCC).
Cap43 protein is expressed at low levels in normal tissues; however, in a variety of cancers, including lung, brain, melanoma, liver, prostate, breast, and renal cancers, Cap43 protein is overexpressed in cancer cells.
