To date, the expression profile of lncRNAs in GC have been screened by different groups and several disordered lncRNAs related to GC carcinogenesis have been investigated, such as MALAT1, HOTAIR, and UCA1(Liu et al., 2014; Li et al., 2017; Wang et al., 2019). The gene discussed is UCA1; the disease is gastric cancer.
