Tissue expression pattern of intronic antisense lncRNAs. (A) Heat map representing the abundance of 4303 RCC-expressed intronic antisense lncRNAs (columns) across other nine human tissues (rows) based on public RNA-seq data [68]. Color intensity represents fractional density expression of each lncRNA across all tissues (see Material and methods for details). There are 628 lncRNAs (out of the 4303; i.e. 15%) at the right hand side of this panel that were exclusively detected in RCC. (B) Heat map indicating the presence (red) or the absence (white) of 1239 RCC-expressed lncRNAs (columns) in seven human cell lineages (rows) from public strand-oriented RNA-Seq libraries [69]. These 1239 intronic antisense lncRNAs represent 29% of the 4303 lncRNAs detected in RCC; the other 3064 lncRNAs (71%) were detected exclusively in RCC, not in the cell lines (not shown). Expression data was hierarchically clustered.
