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). The gene discussed is MCCC2; the disease is breast cancer.
