GGPS1, FDPS, and GART are upregulated in multiple cancers in addition to breast cancer (also TNBC) (Figure 4 and Figure 5, Supplementary Figure S9), including hard-to-treat cancers such as esophageal, pancreatic, lung, and oral cancers and glioblastoma (Figure 2, Supplementary Figures S3 and S9–S11). Here, GGPS1 is linked to breast carcinoma.
