Similar to LINC00668, TUG1 (the first identified lncRNA in a screen for genes up-regulated by developing retinal cells in response to taurine) and LINC00152 (an intergenic lncRNA located in the chromosome 2) are also unregulated and well correlated with outcomes in numerous cancers, including gastric cancer. The gene discussed is TUG1; the disease is gastric cancer.
