SNHG22 was highly expressed in TNBC cells and facilitated TNBC cell growth. a The expression of SNHG22 was tested in TNBC cells and the normal MCF-10A cells through qRT-PCR. b The knockdown efficiency of SNHG22 was detected through qRT-PCR in MDA-MB-231 and MDA-MB-468 cells. c, d Colony formation and EdU experiments were utilized to measure cell proliferation after knockdown of SNHG22. e, f Caspase-3 detection and flow cytometry analysis were utilized to estimate cell apoptosis in these two TNBC cells after silencing SNHG22. g, h Wound healing and transwell experiments were conducted to evaluate cell migration and invasion when SNHG22 was inhibited in indicated TNBC cells. *P < 0.05, **P < 0.01
