Project description:Long non-coding RNAs (lncRNA) play an important role in carcinogenesis, but knowledge of lncRNA expression in renal cell carcinoma is rudimental. We screened 32,183 lncRNA transcripts in malignant and adjacent normal renal tissue and determined dysregulation of approximately 4% of the lncRNA transcripts in clear cell renal cell carcinoma tissue. The distinct changes of lncRNA expression may be used to develop a non-invasive biomarker, because lncRNAs are detectable in bodily fluids.

The distinct changes of lncRNA expression may be used to develop a non-invasive biomarker, because lncRNAs are detectable in bodily fluids. Microarray experiments were performed to determine the expression of 32,183 lncRNA transcripts belonging to 17,512 lncRNAs in 15 corresponding normal and malignant renal tissues
Project description:Non-coding RNAs play an important role in the pathogenesis of human malignancies. So far, microRNAs have been investigated in detail in clear cell renal cell carcinoma, but the knowledge about other small non-coding RNAs like snoRNA, tRNA and piRNA remains small. There is increasing evidence that these non-coding RNAs are also involved in regulation of gene expression, and we therefore performed small RNA sequencing in a cohort of 18 corresponding normal and malignant tissue samples from patients with clear cell renal cell carcinoma. We observed differential expression of microRNAs, but also some dysregulated tRNA and snoRNA in clear cell renal cell carcinoma tissue
Project description:MicroRNAs (miRNAs), non-coding RNAs regulating gene expression, are frequently aberrantly expressed in human cancers. Next-generation deep sequencing technology enables genome-wide expression profiling of known miRNAs and discovery of novel miRNAs at unprecedented quantitative and qualitative accuracy. Deep sequencing was performed on 22 fresh frozen clear cell renal cell carcinoma (ccRCC), 11 non-tumoral renal cortex (NRC) samples and 2 ccRCC cell lines (n=35). The 22 ccRCCs patients belonged to 3 prognostic sub-groups, i.e. Those without disease recurrence, with recurrence and with metastatic disease at diagnosis Deep sequencing was performed on 22 fresh frozen clear cell renal cell carcinoma (ccRCC), 11 non-tumoral renal cortex (NRC) samples and 2 ccRCC cell lines (n=35). The 22 ccRCCs patients belonged to 3 prognostic sub-groups, i.e. Those without disease recurrence, with recurrence and with metastatic disease at diagnosis.

Project description:Analysis of the small non-coding RNA expression profile in cell-free serum RNA of patients with clear cell renal cell carcinoma (RCC) and patients with benign renal tumors (BRT) in order to identify novel non-invasive biomarkers for patients with RCC. Aims: (1) to compare the expression profile of patients with RCC and BRT. (2) to compare the expression profile of patients with localized (M=0) and metastatic (M=1) RCC.
