Fig. 4From: High frequency of intron retention and clustered H3K4me3-marked nucleosomes in short first introns of human long non-coding RNAsExemplary screenshots from UCSC genome browser highlighting the correlation between the layered H3K4me3 bar plots from different cell types (blue, cyan, yellow, red, pink bars) and the available long non-coding transcripts (green lines and bars) from LNCipedia [59]. The black bars represent the user-defined regions. The UCSC genome browser links to the tracks are provided in the supplementary material (Additional file 1: Table S1).Back to article page
