The correlation between four drug–protein pairs and molecular docking of the repurposed drugs onto the potential target proteins. (a,d): Correlation between protein expression and predicted drug response. The figures show the best docking conformation between the protein and the drug (b,e): The three-dimensional interaction diagrams of the best docking conformation for EZH2–AT-13387 and YBX1–KU-55933, respectively. (c,f): Two-dimensional molecular structure diagram of EZH2–AT-13387 and YBX1–KU-55933, respectively.
