Few genome-wide lncRNA-microarray studies have been performed with gastric cancer patients’ plasma and compared their results with healthy control plasma to identify lncRNA signatures, namely FAM49B-AS, GUSBP11, CTDHUT, TINCR, CCAT2, AOC4P, BANCR, and LINC00857, which are upregulated in the plasma from gastric cancer patients [81,82]. This evidence concerns the gene TINCR and gastric cancer.
