An example is in prostate cancer, where upregulated GCN5 downregulates Egr-1 expression via the PI3K/PTEN/Akt signaling pathway, negatively affecting IL-6-induced prostate cancer cell metastasis and epithelial-mesenchymal transition (EMT) (Shao et al., 2018). The gene discussed is PTEN; the disease is prostate carcinoma.
