Background: Prostate cancer is one of the most common malignancies in urology, especially in developed countries. Our previous studies showed that Lanthionine synthase C-like protein 1 (LanCL1) can promote the proliferation of prostate cancer cells and protect cells from oxidative stress. Also, LanCL1 protects cells by inhibiting the JNK signaling pathway after H2O2 treatment.
Materials and Methods: In our study, we analyzed the data of RNA-seq to identify the DEGs after LanCL1 overexpression. We performed a functional enrichment analysis with gene set enrichment analysis (GSEA) and a database for annotation, visualization, and integrated discovery (DAVID). We also identified the critical hub gene correlated with disease prognosis by Cox regression analysis.
Results: A total of 8928 DEGs were identified. Through the analysis of GO and KEGG, we found that DEGs are significantly enriched in categories related to metabolism, cancer-related signaling pathways, and inflammation. The top 15 hub genes were then identified and ranked by degree from the protein–protein interaction network. Survival analysis showed 4 hub genes related to disease prognosis and ICAM1 expression is an independent risk factor for the prognosis.
Conclusion: Our results suggest the critical genes and pathways that might play key roles after LanCL1 overexpression in prostate cancer. We also provide candidate gene targets that might play important roles in prostate cancer development.
