PVT1 and small cell lung carcinoma: This cancer-related region has drawn the attentionof researchers because of its role in DNA rearrangement,direct interaction with c-Myc, and production of abouttwenty lncRNAs and six microRNAs(Colombo et al., 2015).It has been shown that the expression of lncRNA PVT1is associated with enhanced proliferation and invasionof osteosarcoma, small cell lung cancer, and melanoma.Treatment with siRNA-PVT1 results in cell cycle arrest,apoptosis, and the suppression of proliferation(Huanget al., 2016; Zhou et al., 2016; Wang et al., 2018).
