Abstract

The present study aimed to identify the core genes and pathways involved in depression in patients with ovarian cancer (OC) who suffer from high or low‑grade depression. The dataset GSE9116 from Gene Expression Omnibus database was analyzed to identify differentially expressed genes (DEGs) in these patients. To elucidate how certain genes could promote depression in patients with OC, pathway crosstalk, protein‑protein interaction (PPI) and comprehensive gene‑pathway analyses were determined using WebGestalt, ToppGene and Search Tool for the Retrieval of Interacting Genes and gene ontology analysis. Key genes and pathways were extracted from the gene‑pathway network, and gene expression and survival analysis were evaluated. A total of 93 DEGs were identified from GSE9116 dataset, including 84 upregulated genes and nine downregulated genes. The PPI, pathway crosstalk and comprehensive gene‑pathway analyses highlighted C‑C motif chemokine ligand 2 (CCL2), Fos proto‑oncogene, AP‑1 transcription factor subunit (FOS), serpin family E member 1 (SERPINE1) and serpin family G member 1 (SERPING1) as core genes involved in the promotion of depression in patients with OC. These core genes were involved in the following four pathways ‘Ensemble of genes encoding ECM‑associated proteins including ECM‑affiliated proteins’, ‘ECM regulators and secreted factors’, ‘Ensemble of genes encoding extracellular matrix and extracellular matrix‑associated proteins’ and ‘MAPK signaling pathway and IL‑17 signaling pathway’. The results from gene expression and survival analysis demonstrated that these four key genes were upregulated in patients with OC and high‑grade depression and could worsen patients' survival. These results suggested that CCL2, FOS, SERPINE1 and SERPING1 may serve a crucial role in the promotion of depression in patients with OC. This finding may provide novel markers for predicting and treating depression in patients with OC; however, the underlying mechanisms remain unknown and require further investigation.
