Abstract:
Objective To investigate the expression of R-spondin3(RSPO3)in breast cancer and its prognostic value.Methods TIMER,The Cancer Genome Atlas(TCGA),Gene ExpressionProfilling In-teractive Analysis 2(GEPIA2),Human Protein Atlas(HPA)and other databases were used to analyze the differential expression of RSPO3 in breast cancer tissues and normal tissues around cancer,and analyze the correlation between its expression level and pathological parameters of breast cancer;then the expression and structural characteristics of RSPO3 transcripts in breast cancer were investigated by GEPIA2database;Kaplan-Meier Plotter was used to plot the prognosis survival curve between RSPO3 and breast cancer patients;gene ontology(GO)and kyoto encyclopedia of genes and ge-nomes(KEGG)were used for gene function enrichment analysis and metabolic pathway analysis;TIMER database was used to analyzed the relationship between RSPO3 expression level and immune cell infiltration in tumor microenvironment.Results RSPO3 was low ex-pressed in breast cancer,and its expression level was related to the age,tumor diameter and molecular type of breast cancer patients.The low expression of RSPO3 in breast cancer was related to poor prognosis of patients;the results of GO function enrichment analysis showed that RSPO3 interacting genes were mainly enriched in biological processes involving immune cells and their receptors;the results of im-mune cell infiltration analysis showed that the expression level of RSPO3 in breast cancer tissue was positively correlated with the infiltra-tion level of CD8+T cells,CD4+T cells,CD4+T cell memory,macrophages,B cells,etc.It was negatively correlated with the infiltra-tion level of Treg;the results of KEGG metabolic pathway analysis showed that RSPO3may be involved in Wnt/β-catenin pathway.Conclusion Low expression of RSPO3 in breast cancer is related to the poor prognosis of patients,which may be involved in the progres-sion of breast cancer through inhibition of immune cell infiltration and activation of Wnt/β-catenin pathway.
