FABP7 and neoplasm: Single-cell expression analysis revealed that KRT5 and FABP7 were highly enriched in tumor cells, UGT2B4 was predominantly expressed in epithelial cells, BIRC3 and KLRB1 were enriched in CD8+ T cells, while MRC1 and CD209 were highly expressed in monocytes/macrophages (Figure 8D-J and Figure S9).
