POLR1H and gastric cancer: To examine whether lncRNAs transcribed from the chromosome 6p22.1 risk locus contribute to gastric cancer development, we firstly measured levels of three candidate lncRNAs (LINC00240, LINC01012, and ZNRD1-AS1) in paired gastric cancer specimens and normal tissues of Discovery cohort (n = 96) (Fig. 1A).
