Summary (written by the submitters)
we combined their genome-wide profiles of tumors and normal adjacent tissues in 10 ccRCC patients. The results showed that 283 miRNAs were down-regulated and 187 up-regulated, meanwhile 7473 mRNAs were up-regulated and 3439 down-regulated in ccRCC. Expressions of 12 miRNAs and genes were validated in 10 patients we studied by RT-qPCR (validation rate from 60% to 100%).

Differentially expressed gene analysis showed the collective change of miR-200 and SLC22A gene family, and pathway analysis revealed down-regulation of multiple metabolic pathways and up-regulation of focal adhesion, ECM-receptor interaction, etc. Moreover, A miRNA cluster located in chromosome Xq27.3 were significantly down-regulated in ccRCC, which were verified in 53 ccRCC patients by RT-qPCR (validation rate from 63.8% to 88.6%).56 and 586 potentially novel miRNAs and mRNA we detected according to statistical analyses. In addition, 14 miRNA candidates were randomly selected to validate using qRT-PCR and Sanger sequcencing technology, 10 of out 14 could be successfully amplified,.Plus, the sequences of all 5 randomly selected amplified products were confirmed by cloned Sanger sequencing.Our data demonstrated a combined profiling of miRNAs and mRNAs in ccRCC, which showed the decreased metabolism and the perturbation of renal cell function. Moreover, this study identified the expression alteration of a miRNA cluster on Xq27.3, which suggested its potential function in carcinogenesis of ccRCC

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.
