Project description:Generation of a new library of targeted mass spectrometry assays for accurate protein quantification in malignant and normal kidney tissue. Aliquots of primary tumor tissue lysates from 86 patients with initially localized renal cell carcinoma (RCC), 75 patients with metastatic RCC treated with sunitinib or pazopanib in the first line and 17 adjacent normal tissues treated at Masaryk Memorial Cancer Institute (MMCI) in Brno, Czech Republic, or University Hospital Pilsen (UHP), Czech Republic, were used to generate the spectral library. Two previously published datasets (dataset A and B) and two newly generated RCC datasets (dataset C and D) were analyzed using the newly generated library showing increased number of quantified peptides and proteins, depending on the size of the library and LC-MS/MS instrumentation. This PRIDE project also includes quantitative analysis results for all four datasets and raw files for dataset C and D. Dataset A is characterized in DOI: 10.1038/nm.3807. It consists of 18 samples from 9 RCC patients involving one cancer and non-cancerous sample per patient. Dataset B is characterized in DOI: 10.3390/biomedicines9091145. It consists of 16 tumor samples and 16 adjacent normal tissues from 16 mRCC patients treated at Masaryk Memorial Cancer Institute (MMCI) in Brno, Czech Republic. Dataset C involves only tumor tissues from dataset B. Half of them responded to sunitinib treatment in the first line three months after treatment initiation and half did not. Dataset D involves 16 RCC patients treated at University Hospital Pilsen (UHP), Czech Republic. All were localized at the time of initial diagnosis, half of the tumors developed distant metastasis in five years after the diagnosis.
Project description:The aim of this study was to compare effect of everolimus on growth of different renal cell carcinoma (RCC) populations and develop design for experiments to measure the early response of everolimus in clear cell RCC (ccRCC) cell lines including renal cancer stem cells. Gene expression profiling using microarray was performed to determine the early response to everolimus after 3 days of treatment with optimizied concentration of drug in two ccRCC cell lines 1) parental clear cell renal cell carcinoma ccRCC-PCSC (HKPCSC -human parental kidney cancer stem cells) and 2) ccRCC-CSC - clear cell renal cell carcinoma -cancer stem cells (HKCSC - human kidney cancer stem cells).
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:Genotype data from 55 Fulani individuals from Ziniare, Burkina Faso and 7 Czechs & Slovaks collected in Prague, Czech Republic The data was typed in Illumina Omni2.5-Octo BeadChip.
Project description:Aberrant DNA methylation is common in cancer. To associate DNA methylation with gene function, we performed RNAseq upon tumor tissue and matched normal tissues of two ccRCC (clear cell renal cell carcinoma) patients. To quantify 5mC and 5hmC level in each CG site at genome-wide level, we performed BS-seq and TAB-seq upon tumor tissue and matched normal tissues of two ccRCC (clear cell renal cell carcinoma) patients, respectively. mRNA profiles of tumor and matched normal tissues from two ccRCC patients were generated by deep sequencing, using Hiseq 2000. Single-nucleotide-resolution, whole-genome, 5mC and 5hmC profiles of tumor and matched normal tissues from two ccRCC (clear cell renal cell carcinoma) patients were generated by deep sequencing, using Hiseq 2000.

Project description:Clear cell papillary renal cell carcinoma (CCPRCC) is a low-grade renal neoplasm with morphological characteristics mimicking both clear cell renal cell carcinoma (CCRCC) and papillary renal cell carcinoma (PRCC). However, despite some overlapping features, their morphological, immunohistochemical, and molecular profiles are distinct. To better understand the biology of this tumor, we analyze the miRNA expression profiles of a set of CCPRCC by microarrays.
