Although prior studies showed the CTD play a crucial role in colon cancer, breast cancer, and antineuroinflammation through target thioredoxin reductase, detyrosinated tubulin, and CDK2, respectively [26, 32, 33], we found that CTD could inhibit the proliferation of cancer cells by directly targeting AKT expression. The gene discussed is AKT1; the disease is breast carcinoma.
