PDK4 and breast cancer: To explore candidate drug molecules for BC, we considered 8 HubGs-mediated proteins (COL11A1, COL10A1, CD36, ACACB, CD24, PLK1, UBE2C, and PDK4) and 3 regulatory TF proteins (GATA2, SRF, and FOXC1) as the receptors for docking analysis with 142 candidate drug molecules (ligands) that were collected from different sources (see Table S2).
