SNORA68 is upregulated in TNBC cells and is related to TNBC. A The heatmap shows that the expression level of SNORA68 was greater in MDA-MB-231 cells than in MCF-7 cells, as detected by snoRNA sequencing. B qRT‒PCR was used to detect the expression of SNORA68 in human normal breast epithelial cells and breast cancer cells of different subtypes. C qRT-PCR was used to detect the expression of SNORA68 between MCF-7, SKBR3 and TNBC cells. D The expression of SNORA68 in breast cancer was analysed via the SNORic database. E The relationship between SNORA68 and survival among breast cancer patients was analysed via the SNORic database. F SNORic image shows the differential expression of SNORA68 in subtypes of breast cancer.* P < 0.05, ** P < 0.01
