CircEIF3H overexpression significantly promoted TNBC cell proliferation (Fig. 5A), Edu incorporation and colony formation (Fig. 5B and Fig. S8A) in TNBC cells, and HSPD1/RBM8A/G3BP1 knockdown attenuated the cancer-promoting effect induced by the circEIF3H overexpression. This evidence concerns the gene RBM8A and cancer.
