(Submitter supplied) This study investigates the genes that promote clear cell renal cell carcimoma (ccRCC) metastasis using 4 primary metastatic and 5 non-metastatic tumor samples. U133 plus 2.0 array was used to identify the diffrently expressed genes between the primary metastatic and non metastatic ccRCC samples

(Submitter supplied) A total of 3 metastatic and 3 non-metastatic ccRCC tissues were collected from patients. These tissues were flash frozen in liquid nitrogen immediately after surgery and subsequently stored at -80℃. All the resected nodules or metastatic masses were identified as renal tumor by pathologic examination. No patients received anticancer treatments before surgery in this study. We analyzed gene expression microarray data from our gene chip with 3 metastatic ccRCC tissues compared with 3 non-metastatic ccRCC tissues.

(Submitter supplied) Metastatic clear cell renal cell carcinoma (ccRCC) has a poor prognosis and unpredictable course and there are no molecular markers that reliably predict ccRCC metastasis. In this study, specimens from 84 patients with ccRCC were directly cultured in vitro. The primary cultures from 38 of 94 specimens contained more than 90% tumor cells at 4th passages. After identified by immunostaining, the primary cultures of metastatic- and nonmetastatic ccRCC specimens from the age-, gender-matched patients were subjected to cDNA microrray assays. more...

(Submitter supplied) Clear cell renal cell carcinoma (ccRCC), the major histotype of cancer derived from kidney, is lack of robust prognostic and/or predictive biomarker and powerful therapeutic target. We previously identified that follistatin-like protein 1 (FSTL1) was significantly down-regulated in ccRCC at the transcription level. In the present study, we characterized, for the first time, that FSTL1 immunostaining was selectively positive in the cytoplasm of distal convoluted tubules. more...

(Submitter supplied) The understanding of metastatic spread is limited and molecular mechanisms causing particular characteristics of metastasis are largely unknown. This comprises the extremely varying dormancy periods of tumor cells in the secondary organ after metastatic spread, represented by the disease-free survival (DFS) of the patients, or differing numbers of metastases in different patients. Knowing the molecular fundamentals of these phenomena would support the individual prediction of patients´ outcome and facilitate the decision for an appropriate monitoring and therapy regime. more...

(Submitter supplied) MethylCap-Seq experiments of 4 ccRCC cell lines (SKRC1, SKRC10, SKRC52, SKRC59) and one "normal" kidney cell line (HK2) were performed, and used, in combination with DAC/TSA re-expression data, to mine the ccRCC specific cancer methylome. Identified candidate DNA-methylation markers were evaluated by MSP in two independent series, yielding 4 validated markers (GREM1, NEURL, LAD1, NEFH) of which promoter methylation was highly predictive of survival.

(Submitter supplied) MicroRNAs (miRNAs) expression profiles are widely investigated in the major cancers, but their expression in patients plasmas of cancers have not yet to be fully elucidated. We investigated expression profiles of miRNAs in patients preoperative/postoperative plasmas of clear cell renal cell carcinomas (ccRCCs) by using a miRNAs microarray platform which covers a total of 1,523 human miRNAs.

(Submitter supplied) It is unclear how the loss of TGF-b signaling components affects metastatic abilities in clear cell renal cell carcinoma (ccRCC). In this study, we identified that low TGFBR3 expression in ccRCC cells enhanced primary tumor formation and lung metastasis. In the presence of TGFBR3, TGF-b2 decreased the aldehyde dehydrogenase (ALDH)-positive ccRCC cell population, in which renal cancer-initiating cells are enriched. more...

(Submitter supplied) It is unknown if gene expression profiles from primary RCC tumors differ from patient-matched metastatic tumors. Thus, we sought to identify differentially expressed genes between patient-matched primary and metastatic RCC tumors in order to understand the molecular mechanisms underlying the development of RCC metastases.

(Submitter supplied) Tumor-specific alternative splicing is implicated in the progression of cancer, including clear cell renal cell carcinoma (ccRCC). Using ccRCC RNA-sequencing data from The Cancer Genome Atlas, we found that epithelial splicing regulatory protein 2 (ESRP2), one of the key regulators of alternative splicing in epithelial cells, is expressed in ccRCC. ESRP2 mRNA expression did not correlate with the overall survival rate of ccRCC patients, but the expression of some ESRP-target exons correlated with the good prognosis and with the expression of Arkadia (also known as RNF111) in ccRCC. more...

(Submitter supplied) Background: Clear cell renal cell carcinomas (ccRCCs) display divergent clinical phenotypes. Up to one third of patients with local disease at diagnosis will progress. Therefore, it is a need to identify patients at risk for recurrence. In the present study, we analyzed genome-wide promoter DNA methylation at diagnosis in relation to clinicopathological parameters, in order to identify DNA methylation profiles associated with risk for progress. more...
