SLFN5 and neoplasm: According to the TCGA database, the SLFN5, SLFN12, SLFN12L, and SLFN14 expressions in GC were primarily related to T cell infiltration, particularly Tcm cell infiltration, whereas SLFN11 was primarily related to macrophages and dendritic cells (DCs) and SLFN13 was not significantly related to tumor immune cell infiltration (Figures 7A–F).
