Figure 3: Genome-wide profiling of differentially expressed lncRNAs during OSF progression to OSCC. (a) The hierarchical heat map showing different expression pattern of lnRNAs. Red represents relatively high expression and the green represents relatively low expression. (b) Numbers of differently expressed lncRNA transcripts as shown by the histogram. (c) Venn diagram and (d) volcano plot showing differentially expressed lncRNAs in three comparison groups (OSF vs normal, OSCC vs normal and OSCC vs OSF).
