a Volcano plots showing the differential expression of RNAs (lncRNAs, miRNAs, and mRNAs) in breast cancer (BC), which were drawn using the R packages ggplot2; X axis indicates the mean expression differences of lncRNAs, miRNAs, and mRNAs between BC and normal samples, and Y axis represents log transformed false discovery rate (FDR) values. b Heatmaps demonstrate differential expression of lncRNAs, miRNAs, and mRNAs between BC and adjacent normal samples, which were plotted using the pheatmap package; X axis denotes differentially expressed lncRNAs (DElncRNAs), DEmiRNAs, and DEmRNAs and Y axis represents the samples. Blue represents normal samples, while red stands for BC samples. The expression values are shown in line with the color scale
