Background
Renal cell carcinoma (RCC) originates from the renal epithelium and is the most common type of renal cancer with a poor prognosis. As the pathogenesis of kidney renal clear cell carcinoma (KIRC) has not been elucidated, which is necessary to be further explored.
Methods
An expression analysis dataset (GSE126964) was downloaded from the GEO database. Differentially expressed genes (DEGs) between KIRC and normal tissue samples were identified using edgeR and limma analysis. Based on the systematic biology approach of WGCNA, a gene co-expression network was constructed to screen potential biomarkers and therapeutic targets of this disease. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment were performed in the DAVID database.Kaplan-Meier Plotter was used to identify the hub genes associated with overall survival (OS) time of KIRC patients.
Results
A total of 1863 DEGs were identified between the two datasets. Ten co-expressed gene modules were identified using the WGCNA method. GO and KEGG analysis findings revealed that the most enrichment pathways included Notch binding, cell migration, cell cycle, cell senescence, apoptosis, focal adhesions and autophagosomes. Twenty-seven hub genes were identified, among which FLT1, HNRNPU, ATP6V0D2, ATP6V1A, and ATP6V1H were positively correlated with the OS rate of KIRC patients.
Conclusion
In conclusion, DEGs present in both KIRC and normal kidney tissues, which can be considered as the KIRC biomarkers.
