Abstract: OBJECTIVE: To investigate expression of SLC50A1 and its significance in breast cancers (BC).METHODS: Plasma samples from 39 BC patients who met the inclusion criteria of this study were investigated using the enzyme-linked immunosorbent assay.The Mann-Whitney U-test and Kendall's Tau-b were used to analyze differences and correlations between SLC50A1 protein levels and their clinical data.The multivariate Cox regression was used to investigate prognostic significance of SLC50A1 according to the results of the log-rank test.Furthermore,the TCGA database was downloaded to compared different expressions of SLC50A1 from 1 109 BC and 113 adjacent normal tissues.RESULTS: Clinical data from the BC patients indicated that SLC50A1 protein expression was associated with metastasis,hormone receptor and Ki67(P< 0.05).Correlation analyses of plasma SLC50A1 levels indicated a positive correlation between plasma SLC50A1 level and CA153,Kendall's Tau-b=0.257(P=0.004).Multivariate Cox regression analyses indicated that SLC50A1 was an independent prognostic factor in BC patients (HR=0.385,P=0.03).The TCGA data analyses indicated that the SLC50A1 expression levels were higher in BC than in adjacent tissues (P<0.01).CONCLUSION: Plasma SLC50A1 levels were increased in advanced BC,and SLC50A1 expression was an independent prognostic factor for BC.SLC50A1 may be useful as a target for prognosis prediction and therapy of BC.
