Transcriptome network analysis reveals candidate genes for renal cell carcinoma - Abstract

CONTEXT:Renal cell carcinoma (RCC) is a kidney cancer that originates in renal parenchyma and it is the most common type of kidney cancer with approximately 80% lethal cases.

AIMS:To interpret the mechanism, explore the regulation of TF-target genes and TF-pathway, and identify the potential key genes of renal cell carcinoma.

SETTINGS AND DESIGN:After constructing a regulation network from differently expressed genes and transcription factors, pathway regulation network and gene ontology (GO) enrichment analysis were made.

MATERIALS AND METHODS:The gene expression profile set GSE6344, a renal cell carcinoma sample set, was collected from NCBI, pathway data from KEGG, and regulationship data from database TRANSFAC and TRED. Statistical Analysis Used: Besides different expressed genes obtained by limma, impact analysis method and GO enrichment were applied to find the significant expressed pathways.

RESULTS:Finally, we constructed a TF-target gene and TF-pathway regulation network of renal cell carcinoma. And some genes proved to be highly related to renal cell carcinoma were identified.

CONCLUSIONS: This study illustrated that by incorporating significantly expressed pathway into a regulation network based analysis, one can derive greater insights into the underlying mechanisms of renal cell carcinoma.
