Expression patterns of eight one-to-one cis- NATs and the distribution of small RNAs located in overlapped regions of these gene pairs. (A-H) Expression patterns of eight cis- NATs are displayed. The left Y-axis of each graph represents FPKM of each transcript. Blue bars indicate FPKM of plus- transcripts (above the X-axis); red bars indicate FPKM of its partner of minus- transcripts (below the X-axis). The right Y-axis indicates the number of small RNAs located in overlapped regions. The green curves represent unique nat-siRNAs, and the purple curves represent all nat-siRNAs. FPKM refers to Fragments Per Kilobase of exon Models.
