In oncology, Wang and colleagues [20] found that the lncRNA MALAT1 is a biomarker for bladder carcinoma, Xie and his colleagues found that the lncRNA HULC is a biomarker for hepatocellular carcinoma [21], and Zhou and colleagues [22] found that the lncRNA H19 is a possible diagnostic marker for gastric cancer [22]. This evidence concerns the gene H19 and gastric cancer.
