Abstract:
Background: Bladder cancer (BCa) is the most common malignancy of the urinary
system. Inflammation is critical in the occurrence and development of BCa. The purpose of this
study was to identify key genes and pathways of inflammatory bowel disease in BCa through text
mining technology and bioinformatics technology and to explore potential therapeutic drugs for
BCa.
Methods: Genes associated with BCa and Crohn's disease (CD) were detected using the text mining
tool GenClip3, and analyzed using Gene Ontology (GO) and the Kyoto Encyclopedia of
Genes and Genomes (KEGG). A protein-protein interaction (PPI) network was constructed by
STRING and visualized in Cytoscape, and modular analysis was performed using the Molecular
Complex Detection plugin (MCODE). Finally, the genes clustered in the first two modules were
selected as core genes, and the drug-gene interaction database was used to discover potential therapeutic
drugs.
Results: We identified 796 genes shared by "Bladder cancer" and "Crohn's disease" by text mining.
Gene function enrichment analysis yielded 18 enriched GO terms and the 6 most relevant
KEGG pathways. A PPI network with 758 nodes and 4014 edges was constructed, and 20 gene
modules were obtained using MCODE. We selected the top two gene clusters as core candidate
genes. We found that 3 out of 55 selected core genes could be targeted by 26 existing drugs.
Conclusion: The results indicated that CXCL12, FGF2 and FSCN1 are potential key genes involved
in CD with BCa. Additionally, 26 drugs were identified as potential therapeutics for BCa
treatment and management.
