Remodeling of major genomic fabrics and their interplay in metastatic clear cell renal carcinoma

ABSTRACT: Clear cell renal carcinoma (CCRC) accounts for >80% of all kidney cancers but what triggers the tumorigenesis in the kidney and metastases in the bones are still under debate. Our hypothesis is that remodeling of the genomic fabrics of certain functional pathways and their interplay beyond critical limits are key causes of CCRC. We profiled the transcriptomes of metastatic chest wall and of two primary cancerous sites of the renal medulla and compared them with that of non-cancerous kidney resection margins. Samples were collected from a 74 years old male with metastatic carcinoma, consistent with renal cell carcinoma, clear cell type, Fuhrman grade 3, who undergone total right kidney nephrectomy and resection of a chest wall mass. Transcriptomic analysis pointed the tumor region in the right kidney that led to the chest wall metastases. The tumor proved heterogeneous not only in the expression level but also in the expression control, coordination and interplay of pathways responsible for cellular processes and genetic and environmental information processing. The differently regulated pathways in the two sides of the tumor: CCRC, and HIF-1, Vegfa and mTor signaling indicate activation of distinct mechanisms.

Four-conditions (CTR = control - non-cancerous kidney resection margins, PTA = primary tumor side A, PTB = primary tumor side B, MET = chest wall metastasis. Four biological replicates of each condition.

Expression profiling of formalin-fixed, paraffin-embedded (FFPE) breast cancer metastases of the lymph node and autopsy tissues [DASL HumanRef-v3 samples]

Project description:We performed an expression profiling study of 168 primary breast tumors, lymph node metastases, and autopsy samples of primary breast tumours and metastases to liver, chest wall, lymph node, lung, and spleen, as well as positive and negative RNA controls, with technical replicates, to assess quality control methodology and probe-level reproducibility of the Illumina DASL microarray assay. The experiment included both Illumina DASL HumanRef-v3 and DASL HT-12; this series includes only the 120 HumanRef-v3 samples . This series includes 120 samples in total: 19 autopsy tissues of the chest wall, liver, lymph nodes, lung, spleen, liver, and breast, 5 negative controls, 6 positive controls, and 90 lymph node metastases.

Cell-type specific gene programs of the normal human nephron define kidney cancer subtypes

Project description:Comprehensive transcriptome studies of cancers often rely on corresponding normal tissue samples to serve as a transcriptional reference. In this study we performed in-depth analyses of normal kidney tissue transcriptomes from TCGA and demonstrate that the histological variability in cellularity, inherent in the kidney architecture, lead to considerable transcriptional differences between samples. This should be considered when comparing expression profiles of normal and cancerous kidney tissues. We exploited these differences to define renal cell-specific gene signatures and used these as framework to analyze renal cell carcinoma (RCC) ontogeny. Chromophobe RCCs express FOXI1-driven genes that define collecting duct intercalated cells whereas HNF-regulated genes, specific for proximal tubule cells, are an integral part of clear cell and papillary RCC transcriptomes. These networks may be used as framework for understanding the interplay between genomic changes in RCC subtypes and the lineage-defining regulatory machinery of their non-neoplastic counterparts.

Renal Cell Carcinoma Differential Expression

Project description:We investigated the changes in gene expression accompanying the development and progression of kidney cancer using 31,500 element complementary DNA arrays. We measured expression profiles for paired neoplastic and non-cancerous renal epithelium samples from 37 individuals. Using an experimental design optimized for factoring out technological and biological noise, and an adapted statistical test, we find 1738 differentially expressed cDNAs with an expected number of 6 false positives. Functional annotation of these genes provided views of the changes in the activities of specific biological pathways in renal cancer. Cell adhesion, signal transduction, and nucleotide metabolism were among the biological processes with a large proportion of genes overexpressed in renal cell carcinoma. Downregulated pathways in the kidney tumor cells included small molecule transport, ion homeostasis, and oxygen and radical metabolism. Our expression profiling data uncover gene expression changes shared with other epithelial tumors, as well as a unique signature for renal cell carcinoma. Expression data for the differentially expressed cDNAs are available in the web supplement (http://www.dkfz-heidelberg.de/abt0840/whuber/rcc). Keywords = renal clear cell carcinoma, kidney

Expression data from renal cysts of autosomal dominant polycystic kidney disease (ADPKD) patients

Project description:To elucidate the molecular pathways that modulate renal cyst growth in autosomal dominant polycystic kidney disease (ADPKD) Keywords: Disease state analysis We performed global gene profiling on renal cysts of different size (small cysts: less than 1 ml, n=5; medium cysts: between 10-25 ml, n=5; large cysts: greater than 50 ml, n=3) and minimally cystic tissue (MCT, n=5) from five PKD1 polycystic kidneys. Additionally, non-cancerous renal cortical tissue from three nephrectomized kidneys with isolated renal cell carcinoma was used as normal control tissue (n=3). This dataset is part of the TransQST collection.

Expression data from patients with different stages of clear cell renal cell carcinoma

Project description:Clear cell renal cell carcinoma is the most common type among kidney cancers, accounting for 80% of all kidney cancer cases and over 30% of patients have metastases at the time disease is diagnosed. The process od epithelial-mesenchymal transition is crucial for the development and progression of cancer, and here we wanted to check the expression of genes on different stages of tumor progression, and find which of them changes significantly with increased grade.
