Wang et al. developed a lncRNA prognostic model of head and neck squamous cell carcinoma, which included PTOV1-AS2 and found that its expression was significantly higher in cancer tissues than in normal tissues, and PTOV1-AS2 was found to be sensitive to four small molecule drugs (nelarabine, decitabine, acrichine, and dasatinib) [25]. Here, PTOV1 is linked to head and neck squamous cell carcinoma.
