Identification of Prognostic Biomarkers Among DAAM1, FHOD1,FMN2 and INF2 in Breast Cancer Patients
Research Square (Research Square)(2021)
摘要
Background: The formin family proteins are main regulators of actin filaments, which play a crucial role in the migration of cells and carcinogenesis.The specific functions of the formin family proteins in breast cancer still remain unknown.To dissolve this problem,we selected four formin proteins including DAAM1,FHOD1, FMN2 and INF2 and investigated their mRNA expression and survival data in BC(breast carcinoma) patients using diverse databases. Methods: we used these databases including Oncomine, Ualcan, GEPIA 2,HumanProtein Atlas,Metascape,Kaplan-Meier plotter,cBioPortal and TIMER and the software of Cytoscape in our study. Results: DAAM1 and FMN2 were lowly expressed in BC tissues,while FHOD1 and INF2 were highly expressed in BC tissues.The expression levels of DAAM1, FMN2 and FHOD1 were relevant to major subclasses,and the mRNA level of FHOD1 was related to cancer staging.Moreover,High mRNA levels of FHOD1 and INF2 were relevant to poorer prognosis of BC patients,while low mRNA level of DAAM1 was correlated with better prognosis.we also found that there were significant associations between the expressions of DAAM1,FHOD1,FMN2 and INF2 and six types of infiltrated immune cells(B Cells,CD4 + T cells,CD8 + T cells, neutrophil,macrophage,and dendritic cell). Conclusions: our study indicated that FHOD1 and INF2 were potential biomarkers to identify short survival of BC patients,FMN2 was potential prognostic marker to suggest favorable survival of BC patients.
