Project description:Previously, we have reported that genomic loss of 14q occurs more frequently in high grade clear cell renal cell carcinomas (ccRCCs) than low grade ones and shows a significant impact on the expression levels of genes located on this region, suggesting that the genes located on the region and downregulated by the loss may be involved in the malignant transformation of ccRCCs. Here, among the genes located on the minimal common region of 14q loss, we found that 6 were significantly downregulated in high grade ccRCCs due to copy number loss. Using the data set from The Cancer Genome Atlas (TCGA) Research Network, downregulation of one out of the 6 genes, WDR20, was significantly associated with poorer prognosis for the patients with ccRCC, suggesting that downregulation of WDR20 may be involved in the malignant transformation of ccRCC. In functional assays, exogeneous WDR20 significantly inhibited growth and induced apoptosis in RCC cell lines. Interestingly, the phosphorylation levels of ERK and AKT, which reportedly contribute to the malignant phenotype of RCC cells, were clearly reduced by the exogeneous expression of WDR20. Thus, our data suggest that downregulation of WDR20 due to 14q loss may be involved in the malignant transformation of ccRCCs in part through the activation of ERK and AKT pathways. Downregulated expression levels of genes in minimal common region due to 14q loss. Expression levels of 6 genes were determined by microarray analysis and compared between normal kidney tissues (normal, n=16), low grade (low, n=16) and high grade (high, n=16) ccRCCs. The expression level (log2) normalized by the median expression level for the 16 normal samples.

In this array study, we aimed to investigate the effect of WDR20 overexpression on the gene expression profile of an RCC cell line, 786_O. For this aim, we established 3 cell clones stably transfected with the WDR20 expressing vector (786O_WDR20cl1, 786O_WDR20cl2 and 786O_WDR20cl3) and one cell clone stably transfected with the corresponding empty vector (786O_vector) and performed expression microarray analysis using RNAs from these cell lines.

Project description:Non-coding RNAs play an important role in the pathogenesis of human malignancies. So far, microRNAs have been investigated in detail in clear cell renal cell carcinoma, but the knowledge about other small non-coding RNAs like snoRNA, tRNA and piRNA remains small. There is increasing evidence that these non-coding RNAs are also involved in regulation of gene expression, and we therefore performed small RNA sequencing in a cohort of 18 corresponding normal and malignant tissue samples from patients with clear cell renal cell carcinoma. We observed differential expression of microRNAs, but also some dysregulated tRNA and snoRNA in clear cell renal cell carcinoma tissue
