Herein, we sought to investigate the possible role and prognostic value of NPM1 in triple-negative breast cancer (TNBC). Methods: An array of public databases, including bc-GenExMiner v4.0, GOBO, GEPIA, UALCAN, ONCOMINE database and Kaplan-Meier plotter, were used to investigate the expression feature and potential function of NPM1 in TNBC. Immunohistochemistry, immunofluorescence, proliferation and colony formation, flow cytometry and western-blotting assays were used to analyze and verify the function and relevant mechanism of NPM1 in TNBC tissues and cells. Results: According to analysis from bc-GenExMiner, the expression level of NPM1 was significantly higher in basal-like subtypes than luminal-A, HER-2 or normal-like subtypes of breast cancer (P
