(a) The grouped graph of expression correlation of circ0009910 (a), miR-145-5p (b), and PEAK1 (c) in colorectal cancer and adjacent tissue as computed by nonparametric Spearman correlation. (b) Hierarchical clustering showing expression values (log2 transformed) of circ0009910, miR-145-5p, and PEAK1 in CRC samples compared with adjacent colorectal tissues. Red strips indicate high relative expression and green strips indicate low relative expression. The rows and columns show samples and transcripts respectively
