Analysis of blood myelomonocytic cells from RCC patients

ABSTRACT: Myelomonocytic cells (i.e., monocytes or macrophages) play a key role in tumor progression as revealed by numerous mice tumor model studies. However, their contribution in human tumor progression is not well-studied. Using Renal Cell Carcinoma (RCC) as a model for human cancer, we performed a transcriptomal profiling of blood monocytes from RCC patients to investigate the contribution of these cells in cancer progression. As compared to monocytes from healthy donors (Mo), transcriptome analysis of monocytes from RCC patients (RCC-Mo) showed a distinct gene expression signature consisting of cytokines, chemokines and various inflammation-related genes. Validation of these genes by qPCR as well as other functional assays indicated RCC-Mo possess an inflammatory and tumor promoting phenotype.

Blood monocytes from RCC patients (with early or metastatic disease) or healthy donors (controls) were isolated, and then differential gene expression was detected with Limma.

Analysis of classical monocytes from healthy donors, pretreatment RCC patients, and RCC long term survivors.

Project description:Peripheral blood monocytes are the starting material utilized in conventional dendritic cell (DC) vaccination for the treatment of a broad range of malignancies. While the use of cytokines and growth factors to polarize monocyte-derived DC to distinct phenotypes is well-established, little is known about the contributions of distinct human monocyte subsets to monocyte-derived DC function and patient responses to vaccination. To investigate the status of monocyte subsets in cancer patients and following culture into DC, we isolated classical (C-Mo), intermediate (I-Mo), and non-classical (NC-Mo) from the peripheral blood of renal cell carcinoma (RCC) patients prior to DC vaccination (NCT00085436) and from anonymous healthy donors. Patients treated with DC vaccination who were long term survivors (>100 months survival) had a unique monocyte signature with a two-fold higher percentage of NC-Mo in pretreatment peripheral blood compared to other RCC patients. RCC patient monocytes from each subset were transcriptionally distinct from healthy donor monocytes. Further transcriptional analysis determined that each monocyte subset was characterized by a discrete gene expression profile before and after DC maturation. Phenotypic analysis showed that DC derived from NC-Mo expressed higher levels of CD80, CD83, CD86, HLA-DR, and CD40 compared to DC originating from C-Mo and secreted increased amounts of IL-12p70 following CD40L stimulation. Collectively, these findings establish that DC derived from NC-Mo are potent antigen presenting cells and provide the foundation for future vaccination strategies that enrich NC-Mo prior to DC maturation.

Identification of RCC subtype-specific microRNAs – meta-analysis of high-throughput RCC tumor microRNA expression data [miRNA-Seq]

Project description:Renal cell carcinoma (RCC) is one of the most common cancers worldwide with nearly non-symptomatic course till advanced stage of disease. RCC can be distinguished into three subtypes: papillary (pRCC), chromophobe (chRCC) and clear cell renal cell carcinoma (ccRCC) representing up to 75% of all RCC cases. Detection and RCC monitoring tools are limited to standard imaging techniques, in combination with non-RCC specific morphological and biochemical read-outs. RCC subtype identification relays mainly on results of pathological examination of tumor slides. Molecular, clinically applicable and ideally non-invasive tools aiding RCC management are still non-existent, although molecular characterization of RCC is relatively advanced. Hence many research efforts concentrate on identification of molecular markers that will assist with RCC sub-classification and monitoring. Due to stability and tissue-specificity miRNAs are promising candidates for such biomarkers. Here we performed a meta-analysis study, utilized seven available NGS and seven microarray RCC studies in order to identify subtype-specific expression of miRNAs. We concentrated on four potentially oncocytoma-specific miRNAs (miRNA-424-5p, miRNA-146b-5p, miRNA-183-5p, miRNA-218-5p), two pRCC (miRNA-127-3p, miRNA-139-5p) and eight ccRCC specific miRNAs (miRNA-200c-3p, miRNA-362-5p, miRNA-363-3p and miRNA-204-5p, 21-5p, miRNA-224-5p, miRNA-155-5p, miRNA-210-3p) and validated their expression in an independent sample set. Additionally, we found ccRCC-specific miRNAs to be differentially expressed in ccRCC Fuhrman grades and identified alterations in their isoform composition in tumor tissue. Our results revealed that changes in expression of selected miRNA might be potentially utilized as a tool aiding ccRCC subclass discrimination and propose a miRNA panel aiding RCC subtype distinction.

lncRNA_mRNA microarray in RCC

Project description:Recent large-scale transcriptome analyses have yielded large numbers of transcripts, including long non-coding RNAs (lncRNAs) which were found aberrant in various diseases, especially in cancers. But few lncRNAs that may be involved in renal cell carcinoma (RCC) haven't yet been reported.So we aimed to reveal the expression pattern of lncRNAs in 5 paired RCC tumor samples and the matched adjacent normal tissues by microarray.
