HNF1A and gastric cancer: As shown in Fig. 1, the results of lncRNAs expression profile microarray analysis gotten from six GC tissues and their paired adjacent non-neoplastic gastric tissues exhibited that HNF1A-AS1 expression was downregulated in all of the six GC tissues (mean fold change 2.06, p < 0.05), which indicated that this lncRNA may have the potential to be one of the tumor-related LncRNAs.
