In triple-negative breast cancer (TNBC), GUSBP11 reduces the proliferation and migration of TNBC cell lines through the regulation of miR-579-3p/SPNS2.13 GUSB Pseudogene 11 also inhibits the cell proliferation and migration of nasopharyngeal cancer (NPC) through the regulation of the miR-1226-3p/TM9SF4 axis to inhibit the growth of NPC cells.14 The gene discussed is SPNS2; the disease is triple-negative breast carcinoma.
