Our previous studies also demonstrated that CAPE represses the growth of oral squamous carcinoma cells (OSCCs), nasopharyngeal cancer (NPC), and bladder carcinoma cells (BCCs) by activating the MAPK signaling pathway to induce the expression of N-myc downstream regulated 1 (NDRG1) [14,15,16]. The gene discussed is NDRG1; the disease is nasopharyngeal carcinoma.
