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. This evidence concerns the gene THBS1 and neoplasm.
