CMTM6 promotes the survival, migration, invasion and trastuzumab resistance of BC cells in vitro. A qRT-PCR and Western blot validated CMTM6 silencing in JIMT-1 cells and CMTM6-overexpresstion in SKBR3 cells. Negative control (NC) JIMT-1 and SKBR3 cells were transduced with lentivirus for the control shRNA or transfected with the control plasmid, respectively. B, C CCK-8 assay determined the viability of the indicated BC cells following treatment with trastuzumab (0–100 μg/ml). D, E ethynyl-2′-deoxyuridine (EdU) analysis of the proliferation of CMTM6-silenced JIMT-1 cells, CMTM6 overexpressing SKBR3 cells, control JIMT-1 cells and SKBR3 cells following treatment with trastuzumab (10 μg/ml). (scale bar, 50 μM). F, G TUNEL analysis of apoptotic CMTM6-silenced JIMT-1 cells, CMTM6 overexpressing SKBR3 cells, control JIMT-1 and SKBR3 cells following treatment with trastuzumab (10 μg/ml). H, I Cell invasion assay revealed that CMTM6 silencing inhibited JIMT-1 cell invasion while CMTM6 overexpression enhanced SKBR3 cell invasion following treatment with trastuzumab (10 μg/ml). (scale bar, 50 μM). Data are representative images or expressed as the mean ± SD of each group from three independent experiments. *P < 0.05; **P < 0.01; ***P < 0.001

CMTM6 directly interacts with HER2 and enhancing the HER2 signaling in BC cells. A IHC analysis of HER2 protein expression in BC tissues with low or high CMTM6 protein expression (scale bar, 50 μM). B Association between CMTM6 and HER2 protein expression in BC tissues. C Western blot analysis of CMTM6 and HER2 protein levels in BC tissues. D Correlation between CMTM6 and HER2 protein levels in BC tissues. Data are mean ± SEM. E Confocal microscopy analysis of the subcellular co-localization of CMTM6 (green) and HER2 (red) in JIMT-1 cells, with DAPI nuclear staining (blue) (scale bar, 10 μM). F, G Co-immunoprecipitation revealed the direct interaction between endogenous CMTM6 and HER2 proteins in JIMT-1 cells. H Western blot analysis of CMTM6, HER2, p-HER2, PI3K, AKT, MEK, ERK, N-cadherin and E-cadherin protein levels in CMTM6-silenced JIMT-1, CMTM6 overexpressing SKBR3, control JIMT-1 and SKBR3 cells. Data are representative images of each group of cells from three separate experiments
