<h4>Background</h4>Renal neoplasms encompass a variety of malignant and benign tumors, including many with shared characteristics. The diagnosis of these renal neoplasms remains challenging with currently available tools. In this work, we demonstrate the total protein approach (TPA) based on high-resolution mass spectrometry (MS) as a tool to improve the accuracy of renal neoplasm diagnosis.<h4>Methods</h4>Frozen tissue biopsies of human renal tissues [clear cell renal cell carcinoma (n = 7), pa ...[more]

miRNA transcript levels in ccRCC-derived cell lines and proximal tubular epithelial cell samples

Project description:Despite numerous studies reporting deregulated microRNA (miRNA) and gene expression patterns in clear cell renal cell carcinoma (ccRCC), no direct comparisons have been made to its presumed normal counterpart; the renal proximal epithelial tubular cells (PTEC). The aim of this study was to determine the miRNA expression profiles of ten clear cell renal cell carcinoma-derived cell lines and short-term cultures of PTEC, and to correlate these with their gene expression, and copy-number profiles. Using microarray-based methods, a significantly altered expression level in ccRCC cell lines was observed for 23 miRNAs and 1630 genes. The set of miRNAs with significantly decreased expression levels include all members of the miR-200 family known to be involved in the epithelial to mesenchymal transition (EMT) process. Expression levels of 13 of the 47 validated target genes for the downregulated miRNAs were increased more than two-fold. Our data reinforce the importance of the EMT process in the development of ccRCC. For mRNA expression data of these cell lines see GEO Series accession number GSE20491. MicroRNA profiling was performed on two proximal tubular epithelial cell samples (both cell samples were hybridized twice (biological duplicates)) and ten clear cell renal cell carcinoma- derived cell lines (one of which; RCC-JF in duplicate)

MicroRNA expression data from human renal cell cancer subtypes

Project description:MicroRNAs play a vital role in the process of tumorigenesis. To identify and characterize miRNA Expression in renal cell cancer, we performed microarray based screening of miRNA expression profiles in clear cell, papillary type 1 and papillary type 2 renal cell cancer. We selected cases of confirmed clear cell, papillary type 1 and papillary type 2 renal cell carcinoma and generated pairs of tumor and corresponding normal tissue by manual microdissection.

Genome-wide gene expression profiles of clear cell renal cell carcinoma; Identification of molecular targets for treatment of renal cell carcinoma

Project description:In order to clarify the molecular mechanism involved in renal carcinogenesis, and identify molecular targets for diagnosis and treatment, we analyzed genome-wide gene expression profiles of 15 surgical specimens of clear cell renal cell carcinoma (RCC), compared to normal renal cortex, using a combination of laser microbeam microdissection (LMM) with a cDNA microarray representing 27,648 genes. Tissue samples of surgically-resected clear cell renal cell carcinoma (ccRCC) and their corresponding clinical information were obtained from patients with written informed consent. The total of 15 cancer patients (6 women and 9 men; median age, 66; range, 36-75 years) that had been confirmed histologically as ccRCC were selected for this study. Two to three pieces of cancer tissue had been taken from each patient at the time of radical nephrectomy. Normal tissue had been obtained from the distant region from cancer area in the resected kidney tissue. These samples were immediately embedded in TissueTek OCT compound (Sakura, Tokyo, Japan), frozen, and stored at -80°C. The frozen tissues were sliced into 8-μm sections using a cryostat (Sakura) and then stained with H&E for histological examination. We used LMM technology to collect pure populations of ccRCC cells as well as non-cancerous renal cortex. A mixture of normal renal cortex cells in kidney tissues from 11 patients was prepared as a universal control. Experiments were performed using 6 sets of slides (slide set 1-6 corresponding to ID_REF 1-27648).

PRCC_GEX

Project description:Papillary renal cell carcinomas (pRCC) are the second most common form of renal carcinoma, after clear cell Renal carcinoma (ccRCC). PRCC account for 10 to 15% of RCC and gather a heterogeneous population with no specific systemic treatment. Pathological classification by Elbe divides pRCC population in two morphologically different subtypes. Type 1 consists of predominantly basophilic cells, whereas type 2 contains mostly eosinophilic cells. Type 1 architecture corresponds with a single line of cells along the papillary axis, whereas type 2 generally exhibits several cell strata on the axis. Furthermore, type 2 cells demonstrate more aggressive characteristics, such as the presence of nucleoli and increased nuclear size. The papillary cores often contain edema fluid, foamy macrophages, and psammoma bodies. Further clinical reports identified that type I tumors are more likely to present as numerous, bilateral , indolent, low grade pRCC, whereas type II are associated with higher grade and poor prognosis related to metastatic evolution.

Expression data in human renal cell carcinoma samples from patients who did or did not respond to anti-PD-1 (Nivolumab) immunotherapy

Project description:Pre-treatment tumor expression of PD-L1 has been shown to correlate with favorable clinical outcomes following PD-1 blocking therapies. However, the majority of patients with PD-L1+ tumors do not respond to treatment. With the goal of obtaining insights into the mechanisms underlying the response to anti-PD-1 targeted therapies in patients with renal cell carcinoma (RCC) with positive tumor expression of PD-L1, microarray expression data was obtained for pre-treatment tumors from patients with RCC who did or did not have a positive response to anti-PD-1 (nivolumab) therapy. Insight into these mechanisms may lead to improved rationally designed therapies, and biomarkers for selecting patients who are more likely to benefit from these treatments. Gene expression profiling was performed on total RNA extracted from 11 formalin-fixed paraffin-embedded (FFPE) RCC specimens, 4 of which were from patients who had a positive response (objective tumor regression) to the anti-PD-1 (nivolumab) immunotherapy, and 7 of which were from patients who did not have a response.
