We compared our module 3 osteosarcoma genes (Fig 8 and S7 File) with the four consensus modules of Jin et al. [45] and found that six of our biomarker candidates were also in Jin’s consensus module 1, these genes are SPARC, COL6A3, PCOLCE, CALD1, ITGB5, and DPYSL3. Here, PCOLCE is linked to osteosarcoma.
