MiRNA expression of papillary renal neoplasm with reverse polarity (PRNRP) cases

ABSTRACT: Between 80% and 90% of renal carcinomas are either clear cell renal cell carcinoma or papillary RCC although there are at least 20 other distinct forms of RCC recognised by the World Health Organization (WHO). Emerging or provisional entities have been considered as variants of PRCC, including papillary renal neoplasm with reversed polarity (PRNRP). However, the molecular basis of PRNRP, and miRNA expression profile, is unknown. We used microarray analysis to elucidate the non-coding RNA (ncRNA) profiles of 10 PRNRP cases and compared them with other renal neoplasms. Cases were only considered for this study after fulfilment of strict inclusive histological and immunohistochemical criteria. We used Affymetrix miRNA v.4.0 arrays to elucidate the expression of these samples.

Gene expression of papillary renal neoplasm with reverse polarity (PRNRP) cases + PRCC cases

Project description:Between 80% and 90% of renal carcinomas are either clear cell renal cell carcinoma or papillary RCC although there are at least 20 other distinct forms of RCC recognised by the World Health Organization (WHO). Emerging or provisional entities have been considered as variants of PRCC, including papillary renal neoplasm with reversed polarity (PRNRP). However, the molecular basis of PRNRP is unknown. We used microarray analysis to elucidate the gene profile of 10 PRNRP cases and an additional 7 PRCC cases. Cases were only considered for this study after fulfilment of strict inclusive histological and immunohistochemical criteria. We used Affymetrix Clariom D human arrays to elucidate the expression of these samples.

microRNA profiling in renal cell carcinoma subtypes

Project description:Renal cell carcinoma is the most common neoplasm of the adult kidney. A few subtypes of RCC include papillary RCC (pRCC), chromophobe RCC (chRCC) and the benign oncocytoma tumor. In some cases, distinguishing between the RCC subyptes is difficult. We performed a mircroRNA (miRNA) microarray to determine differential miRNA expression between pRCC, chRCC, and oncocytoma. We performed a miRNA microarray on 10 tumor samples of each papillary renal cell carcinoma (pRCC), chromophobe renal cell carcinoma (chRCC), and oncocytoma.

miRNA expression of Tubulocystic Renal Cell Carcinoma (TC-RCC) cases

Project description:Eleven TC-RCC cases were selected on the basis of the criteria defined by the 2012 Vancouver Classification of Renal Neoplasia and WHO 2016 classification criteria, and re-reviewed by a panel of expert renal pathologists. Two of these cases, TC-RCC#9 and #10, had a mixed tubulocystic and papillary histology and were macro-dissected into separate PRCC and TC-RCC components. The molecular basis of TC-RCC, and miRNA expression profile, is unknown. We therefore used Affymetrix miRNA v.2. arrays to elucidate the expression of these samples

Renal cells Carcinoma (RCC) Genome variation profiling by genome tiling array with Nimblegen CGX6 platform

Project description:Papillary renal cell carcinoma (pRCC) is the second most frequent renal cell carcinomas (RCC) after clear cell RCC. In contrast to clear cell RCC, there is no consensual protocol using targeted therapy for metastatic pRCC. Moreover, diagnosis of some pRCC, especially pRCC of type 2 (pRCC2) may be challenging. Our aim was to identify molecular biomarkers that could be helpful for the diagnosis and treatment of pRCC.

Analysis of microRNA expression profiles in Xp11 renal cell carcinoma compared to normal adjacent tissue.

Project description:Renal cell carcinomas (RCCs) with Xp11 translocation (Xp11 RCC) constitute a distinctive molecular subtype characterized by chromosomal translocations involving the Xp11.2 locus, resulting in gene fusions between the TFE3 transcription factor with a second gene (usually ASPSCR1, PRCC, NONO, or SFPQ). RCCs with Xp11 translocations comprise up to 1-4% of adult cases, frequently displaying papillary architecture with epithelioid clear cells.
