LINC00662 is overexpressed in BC tissues and promotes cell proliferation, migration, invasion and stemness. A QRT-PCR analysis was applied to detect LINC00662 expression in normal tissues and tumorous tissues. The mean, SD and 95% CI have been provided in Additional file 6: Table S4. B QRT-PCR analysis was applied to detect LINC00662 expression in MCF-10A, MDA-MB-231, MCF-7, MDA-MB-468 and MDA-MB-453. C QRT-PCR was employed to examine the efficiency of sh-LINC00662#1/2/3. D Cell colony formation assay disclosed cell proliferative ability after the silencing of LINC00662 in MDA-MB-231 and MCF-7 cells. E Transwell assays were conducted to investigate cell migratory and invasive ability after knockdown of LINC00662 in BC cells. F Sphere formation assay was applied to detect cell stemness after LINC00662 knockdown in BC cells. G Western blot assay was conducted to examine the levels of stemness-related proteins after LINC00662 ablation in BC cells. ^**p < 0.01
