HOST2 promoted proliferation and invasion of TNBC cells in vitro. a, b qRT-PCR was conducted to verify the relative expression of HOST2 in MDA-MB-231 and MDA-MB-468 cells transfected with HOST2-siRNA (si-HOST2). c, d MTT assay was performed to determine the cell viability in MDA-MB-231 and MDA-MB-468 cells after knockdown of HOST2. e, f Representative results of the EDU assay of MDA-MB-231 and MDA-MB-468 cells after knockdown of HOST2. g, h Effects of HOST2 knockdown on cell colony formation ability in MDA-MB-231 and MDA-MB-468 cells. i, j Representative results of transwell invasion assay of MDA-MB-231 and MDA-MB-468 cells after knockdown of HOST2. ^*P < 0.05, ^**P < 0.01. All experiments were repeated three times
