Network construction of rhein targets. a Rhein target protein–protein interaction network (PPI). b Extended rhein target PPI network (EPPI). In these networks, each node is a protein, and an edge indicates that two proteins interact with each other. Purple nodes represent known rhein targets; green nodes represent potential rhein targets; light blue nodes represent extended adjacent proteins of rhein targets
