Researchers who applied linalool to the HeLa cell line observed increased expression in genes including TP53 (encoding the p53 tumor suppressor protein), CDKN1A (p21), CDKN1B (p27), CDKN2A (p16), and CDKN2C (p18), all of which facilitate and direct tumor suppression [76]. The gene discussed is TP53; the disease is neoplasm.
