The SNORA71B promoted proliferation of different metastatic capacity BC cells. a qRT-PCR analysis of relative SNORA71B expression in siSNORA71B-infected high BM BC cells (MDA-MB-231BM). b The relative expression of pcDNA3.1-SNORA71B in SNORA71B-transfected low BM BC cells (MDA-MB-231) using qRT-PCR assay. c, d qRT-PCR detected expression stability of SNORA71B expression at 24 h, 48 h, 72 h, and 96 h after pcDNA3.1-SNORA71B and siSNORA71B transfection. e, f CCK8 assays were utilized to evaluate effect of SNORA71B on the proliferation abilities of the high and low BM BC cells (MDA-MB-231BM, MDA-MB-231). Values are indicated as mean ± SD from three independent experiments. *P < 0.05, **P < 0.01
