Among them, the genes contained in GO 0019882 were TAP1, PSMA8, PSMD9, THBS1, KIF3A, HLA-DPA1, RAB10; Pathway hsa04612 contained the following genes: HLA-DPA1, NFYA, RFX5, TAP1. The above experimental data confirmed that tRF-17-79MP9PP could inhibit breast malignant activities of cancer cells, so its target gene should be associated with tumor cell invasion, metastasis or proliferation. Here, RFX5 is linked to neoplasm.
