Figure 5. Top GO terms associated with TNS1 and immunohistochemical analysis of TNS1 expression in BCa and normal urothelial tissues. (A) STRING database analysis shows the protein interaction network between TNS1 and TNS1-related proteins. The nodes represent proteins and the lines represent protein-protein interactions. (B) Top 10 GO terms related to TNS1 and TNS1-related proteins based on functional enrichment analysis using DAVID. The blue bars represent the number of TNS1-related genes in each GO term. (C) Immunohistochemical analysis results show TNS1 protein expression in BCa and adjacent normal urothelial tissues from T1, T2, T3 and T4 stage BCa patients.
