BACKGROUND No validated renal cell carcinoma (RCC) marker is known for detection of asymptomatic disease in selected populations or for prognostic purposes or treatment monitoring. We identified immunogenic proteins as tumor markers for RCC by combining conventional proteome analysis with serological screening, and we investigated the diagnostic clinical value of such markers in serum. METHOD...

Despite high protein expression and enzymatic activity of cytochrome P450 1B1 (CYP1B1) in renal cell cancer (RCC), its functional significance has not been elucidated. Here we explored the functional role and regulatory mechanism of CYP1B1 in RCC. Reduction of CYP1B1 levels fail to prevent in vitro tumorigenicity such as proliferation, apoptosis, and cell cycle progression of RCC cells. Moreove...

von Hippel-Lindau (VHL) disease is a cancer syndrome, which includes renal cell carcinoma (RCC), and is caused by VHL mutations. Most, but not all VHL phenotypes are due to failure of mutant VHL to regulate constitutive proteolysis of hypoxia-inducible factors (HIFs). Janus kinases (JAK1, 2, 3, and TYK2) promote cell survival and proliferation, processes tightly controlled by SOCS proteins, whi...

Microarray gene expression profiles of both renal cell carcinoma (RCC) tissues and a RCC cell line were analyzed using singular value decomposition (SVD) and functional clustering. The SVD projections of the expression profiles revealed significant differences between the profiles of RCC tissues and a RCC cell line. Based on the biological processes, selected genes were annotated and clustered ...

Renal cell carcinoma (RCC) originated from parenchyma and the majority of malignancies originating in the renal pelvis are transitional cell carcinoma (TCC). In the present study, a rare case of RCC growing into the renal pelvis and mimicking TCC in medical imaging is reported. The preoperative differentiation between RCC and TCC is important in order to identify the type of surgical treatment ...

While irradiation of red cell concentrates (RCC) prevents graft-versus-host disease in susceptible transfusion recipients, it also damages red blood cells (RBC). To understand the ability of irradiation regulations to prevent transfusion of inferior units, we irradiated 980 RCC in saline-adenine-glucose-mannitol (SAGM) using various combinations of pre-irradiation age and post-irradiation stora...

Renal artery aneurysms (RAAs) are a rare condition; however, the coexistence of an RAA with renal cell carcinoma (RCC) is extremely rare. The present study reports the case of a patient found to simultaneously have an operable RAA and RCC. The patient was treated by radical nephrectomy. Surgical intervention for RAA is controversial, and the appropriate treatment for RCC with RAA has not been w...

Renal cell carcinoma (RCC) in autosomal dominant polycystic kidney (ADPKD) is rare. To date, 54 cases of RCC in ADPKD have been reported. Among these, only 2 cases have different histologic types of RCC. Here we describe a 45-year-old man who received radical nephrectomy for multifocal RCC with synchronous papillary and clear cell histology in ADPKD and chronic renal failure under regular hemod...

Targeting mTOR (mammalian target of rapamycin) is an effective approach in the treatment of advanced RCC (renal cell carcinoma). Rapamycin-like drugs (rapalogues) have shown clinical activities and have been approved for the treatment of RCC. Recently, with the development of ATP-competitive inhibitors of mTOR, therapies targeting mTOR have entered a new era. Here, we discuss the biological rel...
