Sixteen downregulated DEPs with anti-tumorigenic potential (YWHAZ, TUBB2A, HSPB1/HSP27, HNRNPK, PCBP2, MCCC2, UGDH, TPI1, ATP5F1B, DLST, FTL, HYOU1, PRDX6, RPL31, RPL7A, and RPS3) were submitted for protein–protein interaction (PPI) network construction with the STRING database (https://string-db.org/, accessed on 19 September 2023) to emphasize the specific interaction network associated with JTBhigh condition in the MCF7 BC cell line (Figure 1). This evidence concerns the gene UGDH and breast cancer.
