ZNF667 and head and neck squamous cell carcinoma: Also other lncRNAs are upregulated in HNSCC and may display oncogenic properties, such as ZFAS1 (Kolenda et al. 2019), PVT1 (Yu et al. 2018), CASC9 (Sassenberg et al. 2019), TUG1 (Zhang et al. 2018b), MIAT (Zhong et al. 2019), SNHG20 (Wu et al. 2019), or RGMB-AS (Xu and Xi 2019), or downregulated and may act as tumor suppressor genes, such as STR5-AS (Wang et al. 2019a), C5orf66-AS1 (Lu et al. 2018), AC012456.4 (Hu et al. 2018b), LINC01133 (Kong et al. 2018), ZNF667, and ZNF667-AS1 (Meng et al. 2019).
