Fig. 4From: Identification and functional analysis of a three-miRNA ceRNA network in hypertrophic scarsPPI networks of miR-422a (a), miR-2116-3p (b), and miR-3187-3p (c), with top 10, 20, and 20 hub genes (highlighted), respectively. The node size increased in proportion to its degree, which was calculated by the built-in algorithm in Cytoscape. PPI, protein–protein interactionBack to article page
