PVT1 and cervical carcinoma: Several lncRNAs, including HOTAIR [17], H19 [18], mucosa-associated lymphoid tissue 1 (i.e., MALT1) [19], growth arrest-specific 5 (i.e., GAS5) [20], cervical carcinoma high expressed 1 (i.e., CCHE1) [17], and Pvt1 oncogene (i.e., PVT1) [21], are crucial in tumorigenesis, invasion, metastasis, and radio-resistance [22–24].
