XCR1 and malignant colon neoplasm: SCD1 expression was significantly correlated with β-catenin expression that was inversely correlated with CD8a and XCR1 (figure 4D) as previously reported in human melanoma.18 These results indicate that the SCD1/β-catenin/CCL4 pathway may also be involved in the non-T cell inflamed subtype of human colon cancer.
