Abstract
OBJECTIVE
To investigate the expression and significance of GDF3 in testicular cancer through bioinformatics analysis.
METHODS
Using the TCGA and GTEx databases, differential expression analysis and pan-cancer analysis were performed to identify the target gene GDF3, and the clinical relevance of GDF3 in testicular cancer was analyzed using the UALCAN database. Based on the R packages "org.Hs.eg.db" and "clusterProfiler," gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were conducted to explore the potential functions of GDF3 in testicular cancer. The correlation of GDF3 with immune chemokines and immune inhibitors in testicular cancer was investigated using the TISIDB database.
RESULTS
The GDF3 was significantly upregulated in testicular cancer (P<0.001) and closely associated with clinical staging (P<0.05) and tumor subtypes (P<0.001). The immune-related analysis revealed that GDF3 was strongly correlated with immune chemokines CCL26 (rho=0.599, P<0.001), CCL7 (rho=0.525, P<0.001), immune inhibitor ADORA2A (rho=0.723, P<0.001), and PVRL2 (rho=0.585, P<0.001).
CONCLUSION
The GDF3 is closely related to the occurrence, development, and immune microenvironment of testicular cancer.
