Fig. 1. Expression distributions for 55 most highly expressed microRNA 5'-isoforms in a sample of colorectal cancer tissues. Horizontal lines in the boxes are median values, box limits correspond to lower and upper quartiles, whisker termini correspond to minimal and maximal values
Fig. 2. Regulatory network of interactions among microRNA isoforms, their targets and transcription factors. Blue, green and red colors correspond to microRNA 5'-isoforms, transcription factors and target genes, respectively. The edges are colored in accordance with the type of regulator. The vertex sizes are linearly related to degrees
Fig. 3. Strongly connected subgraph of interactions between microRNA 5'-isoforms and transcription factors. Ellipses and rectangles denote microRNA isoforms and transcription factors, respectively. Arrows correspond to expression activation, blunt-end lines correspond to expression inhibition
