ABSTRACT
Objective To investigate the expression of CD276 in pan-cancer,its effect on patient prognosis,and its mechanism of action.Methods TCGA and GTEx databases were used to study the differential expression of CD276 in tumor and normal tissues;R language was used to analyze the effects of CD276 on the prognosis of patients with pan-cancer,the tumor microenvironment,the tumor mutation burden,and microsatellite instability;the correlation between the expression of CD276 in tumor tissues and the tumor immune cell infil-tration was further examined;the biological function of CD276 was analyzed using Gene Set Enrichment Analysis(GSEA);and finally,real-time PCR was used to validate the expression of CD276 in tumors in vitro.Results A statistical difference in CD276 expression was detected between tumor and normal tissues(P<0.05).CD276 affects tumor prognosis and is strongly associated with the tumor microenvi-ronment,tumor mutational burden,microsatellite instability,and tumor immune cell infiltration.Conclusion Comprehensive pan-cancer analysis identified CD276 as a biomarker for immune infiltration and poor cancer prognosis,which can be used as a novel immunomodula-tory target for the development of immunotherapeutically-targeted drugs,providing new ideas for tumor therapy.
