GSEA by c2wikipathway database showed that CXCR2P1 was significantly enriched to Interactions Between Immune Cells And MicroRNAs In Tumor Microenvironment (2.402 x 10-3, shown as Figure 6A), which indicated that CXCR2P1 might regulate the expression of PD-L1 through microRNAs. Here, CD274 is linked to neoplasm.
