Expression of FATP1 in the TAME is tightly linked to the polarization of CD163+macrophage and predicts survival in breast cancer.
(a) Comparison of FATP1 mRNA expression in normal and tumor breast tissues in the TCGA datasets. (b) FATP1 mRNA expression in different breast cancer subtypes in the breast cancer cohort of TCGA. (c) Correlation analyses between the protein expression levels of FATP1 and CD163 in the TCGA datasets. (d) Kaplan-Meier plots of human BRCA specimens from the TCGA datasets (1082 patients) based on low vs. high gene expression of FATP1. (e) Representative immunohistochemical images of FATP1 in tumor invasive margins and tumor tissues, respectively. (f, i) Kaplan-Meier survival analysis of patients with FATP1-positive and -negative IHC staining in the margin or tumor tissues, respectively. (g, j) Correlation analyses between the protein expression levels of FATP1 and CD163 in the margin or tumor tissues, respectively. (h) Kaplan-Meier survival analysis of patients with biomarker-positive and -negative IHC staining in the margin.*, p < .05; **, p < .01; ***, p < .001; ****, p < .0001; ns, not significant; Correlation calculations represent Pearson’s coefficient.
