Clear cell renal cell carcinoma is by far the most common form of kidney cancer; however, a number of histologically similar tumors are now recognized and considered distinct entities. The Cancer Genome Atlas published data set was queried (http://cbioportal.org) for clear cell renal cell carcinoma tumors lacking VHL gene mutation and chromosome 3p loss, for which whole-slide images were reviewed. Of the 418 tumors in the published Cancer Genome Atlas clear cell renal cell carcinoma database, 387 had VHL mutation, copy number loss for chromosome 3p, or both (93%)...

A whole-transcriptome analysis of gene expression in six samples of clear cell renal cancer was performed. Using bioinformatics methods, we established a relationship between gene expression data and changes in activity of metabolic pathways: in this cancer type, the expression of genes involved in the metabolism of carbohydrates, lipids, and amino acids as well as in energy metabolism changed most significantly.

Cytosine5-hyxymethylation (5hmC)which is a new epigenetic modification form plays important roles in the development and progression of tumors. In the present study, we observed that levels of 5hmC in the promoter region of Von Hippel-Lindau (VHL) were lower in 97 samples of renal clear cell carcinoma tissue than in matched adjacent benign tissues. Moreover, when the cancer tissue samples were divided based on pathological staging, VHL expression and the level of 5hmC in the VHL promoter were both lower in pathological grade III tumors than in grades I or II...

A 64-year-old man with a lesion of the pancreatic tail was referred for Ga-DOTATATE PET/CT imaging. His medical history included previous metastatic clear cell renal cell cancer. Ga-DOTATATE PET/CT demonstrated increased DOTATATE uptake (SUVmax 10.5) in a pancreatic tail lesion. Histopathology of the resected lesion confirmed clear renal cell cancer metastasis. This case illustrates that clear cell renal cancer metastasis can demonstrate Ga-DOTATATE accumulation.

AIM: In 2012, the International Society of Urological Pathology (ISUP) introduced a novel grading system for clear cell and papillary renal cell carcinoma (RCC) based upon increasing nucleolar prominence in grades 1 to 3, with the presence of extreme nuclear pleomorphism and/or tumour giant cells and/or sarcomatoid and/or rhabdoid differentiation as criteria for grade 4. This system is now incorporated in the latest World Health Organization renal tumour classification, being designated WHO/ISUP grading...

Clear cell renal cell carcinoma (ccRCC) is a common urologic malignancy. Long non-coding RNA colon cancer-associated transcript 2 (CCAT2) has been suggested as serving pivotal roles in tumorigenesis. However, the clinical significance and biological role of CCAT2 in ccRCC remains elusive. The purpose of this study is to identify the function of CCAT2 in ccRCC and its possible molecular mechanism. Expression of CCAT2 was analyzed in 61 ccRCC tissues and two ccRCC cell lines (786-O and ACHN) by quantitative reverse transcription polymerase chain reaction...

Neddylation is a post-translational protein modification associated with cancer development. MLN4924 is a neddylation inhibitor currently under investigation in multiple phase I studies on various malignancies, and its clincal name is Pevonedistat. It has been documented that MLN4924 blocks Cullins neddylation and inactivates CRLs and, in turn, triggers cell-cycle arrest, apoptosis, senescence and autophagy in many cancer cells. In this study, we investigated the anti-tumor effect of MLN4924 in human clear cell renal carcinoma (ccRCC)...

<p>Clear cell renal cell carcinoma (ccRCC) is the most common type of kidney cancer and it forms highly vascularized tumors. The monocyte endoribonuclease MCPIP1 negatively regulates inflammation by degrading mRNA encoding proinflammatory cytokines, such as IL-6, IL-1 and IL-12. MCPIP1 is also a negative regulator of NFκB and AP1 activity and it influences a broad range of miRNA activities. Here we report that MCPIP1 protein levels are decreased during renal cancer progression. In patient-derived tumors, and xenografts established in NOD-SCID or nude mice, low MCPIP1 levels correlated strongly with increased proliferation, tumor outgrowth and vascularity...

BACKGROUND AND OBJECTIVE: Small kidney cancers are a heterogeneous group with varying malignant potential. Pathologic information obtained from a renal biopsy may guide decision-making for small kidney cancers. We sought to assess the effect of pathologic information from renal biopsy on the nonsurgical management of small kidney cancers in a population-based cohort of patients over 65 years of age. METHODS: In the Surveillance, Epidemiology and End Results-Medicare dataset, we identified patients ≥66 years diagnosed with a kidney cancer<4cm between 2002 and 2011...

Sarcomatoid renal cell carcinoma (SRCC) ranks among the most aggressive clinicopathologic phenotypes of RCC. However, the paucity of high-quality, genome-wide molecular examinations of SRCC has hindered our understanding of this entity.<br /><br />Experimental Design: We interrogated the mutational, copy number, and transcriptional characteristics of SRCC and compared these data with those of non-sarcomatoid RCC (RCC). We evaluated whole exome sequencing, single nucleotide polymorphism, and RNA sequencing data from patients with SRCC (n=65) and RCC (n=598) across different parent RCC subtypes, including clear cell RCC, papillary RCC, and chromophobe RCC subtypes...

Inactivation of the von Hippel-Lindau tumor suppressor protein (pVHL) is the signature lesion in the most common form of kidney cancer, clear cell renal cell carcinoma (ccRCC). pVHL loss causes the transcriptional activation of hypoxia-inducible factor (HIF) target genes, including many genes that encode histone lysine demethylases. Moreover, chromatin regulators are frequently mutated in this disease. We found that ccRCC displays increased H3K27 acetylation and a shift toward mono- or unmethylated H3K27 caused by an HIF-dependent increase in H3K27 demethylase activity...

BACKGROUND: The focus of tumour-specific antigen analyses has been on single nucleotide variants (SNVs), with the contribution of small insertions and deletions (indels) less well characterised. We investigated whether the frameshift nature of indel mutations, which create novel open reading frames and a large quantity of mutagenic peptides highly distinct from self, might contribute to the immunogenic phenotype. METHODS: We analysed whole-exome sequencing data from 5777 solid tumours, spanning 19 cancer types from The Cancer Genome Atlas...

We investigated the expression level of p53 upregulated modulator of apoptosis (PUMA), myeloid cell leukemia-I (MCL-1), and p53 in renal cell carcinoma (RCC) and para-carcinoma tissues, as well as their clinical significance. The expression levels of PUMA, MCL-1, and p53 in RCC and para-carcinoma tissues were measured using immunohistochemical and quantitative real-time PCR methods. Correlations between protein expression and pathological characteristics were analyzed. Renal clear cell carcinoma showed elevated MCL-1 and p53 protein expression (P > 0...

Renal cell carcinoma (RCC) is one of the most aggressive urologic cancers, however, the mechanism on supporting RCC carcinogenesis is still not clear. By using gene expression profile analysis and functional clustering, PDZ domain-containing 1 (PDZK1) was revealed to be downregulated in human clear cell renal cell carcinoma (ccRCC) samples, which was also verified in several independent public ccRCC data sets. Using PDZK1 overexpression and knockdown models in ccRCC cell lines, we demonstrated that PDZK1 inhibited cell proliferation, cell cycle G1/S phase transition, cell migration and invasion, indicating a tumor-suppressor role in the development and progression of ccRCC...

CD163 is preferentially expressed by monocyte/macrophages; however, recent studies using immunohistochemistry (IHC) have reported that some cancer cells also express CD163. In the present IHC study, we investigated CD163 staining of cancer cells and macrophages in clear cell renal cell carcinoma (ccRCC) tissues and determined the relationship between cancer cell CD163 expression and clinical prognosis in patients with ccRCC. IHC for CD163 was performed in ccRCC tissues from 103 patients. CD163-positive cancer cells were detected in 35% of the patients (36/103); however, the positive signals on cancer cells were significantly lower than those on macrophages...

Caveolin-1 (CAV1) has been identified to be up-regulated in many cancers, including clear cell renal cell carcinoma (ccRCC). However, its potential function is still unclear in ccRCC. In this study, we demonstrated that CAV1 was frequently overexpressed in renal cell carcinoma tissues and cells, and was significantly associated with various clinicopathological parameters. In addition, high CAV1 expression was associated with poor disease-free survival (DFS) rate and could serve as a useful diagnostic indicator in ccRCC patients with different clinicopathological stages...

BACKGROUND: A key feature of clear cell renal cell carcinoma (ccRCC) is the inactivation of the von Hippel-Lindau tumour suppressor protein (pVHL) that leads to the activation of hypoxia-inducible factor (HIF) pathway also in well-oxygenated conditions. Important regulator of HIF-α, prolyl hydroxylase PHD3, is expressed in high amounts in ccRCC. Although several functions and downstream targets for PHD3 in cancer have been suggested, the role of elevated PHD3 expression in ccRCC is not clear...
