Other well-described oncogenic lncRNAs involved in BC include MALAT1, HOTAIR, TUG1, ANRIL and PVT1, whereas well-known lncRNAs-MEG3 and GAS5 represent tumor suppressor lncRNA molecules (Sun et al., 2015; Gulìa et al., 2017; Guo et al., 2018; Liu et al., 2017b; Xie et al., 2017a; Yang et al., 2017; Yu et al., 2019; Jiao et al., 2018; Liu et al., 2018a; Wang et al., 2018b; Huang et al., 2019a; Tian et al., 2019). Here, HOTAIR is linked to breast cancer.
