In contrast, SLC35A2 was found to have negative correlations with cancer-associated fibroblast XCELLs, and CD8+ T cells in the HER2 subtype; natural killer (NK) cell-activated CIBERSORT-ABS in the luminal A subtype, and hematopoietic stem cells in the luminal B subtype. Here, SLC35A2 is linked to cancer.
