From: Trend analysis of the role of circular RNA in goat skeletal muscle development
Characterization and expression patterns of circRNAs in goat skeletal muscle. a Types of circRNAs in goat skeletal muscle. b Number of exons contained in goat circRNAs. c Distribution of all identified circRNAs on goat chromosomes. The histogram indicates the circRNA density of each chromosome. d Principal component analysis (PCA) of circRNA in 21 goat skeletal muscle samples. Similar colors represent the same phase. Arrows indicate the direction of progression between successive muscle stages. e Unsupervised clustering of all circRNAs identified in goat skeletal muscle
