BSG and neoplasm: Pearson Correlation analysis of CD147 protein or mRNA and miR-890 in TNBC was performed, and the data showed that in 20 TNBC tumor samples, miR-890 level was inversely correlated with CD147 protein (Correction coefficient = − 0.702, P = 0.001) but not CD147 mRNA (Correction coefficient = − 0.360, P = 0.119) (Fig. 1b).
