Expression of LncRNA AK023391 was upregulated in gastric cancer (GC). a LncRNA microarray analyses of five GC tissue samples and five corresponding adjacent normal tissues were performed. b LncRNA microarray identification of AK023391 and the most obvious changes in 20 upregulated lncRNAs and four downregulated lncRNAs. c qRT-PCR verification of the expression levels of 20 upregulated lncRNAs in GC tissues. d LncRNA expression profile and qRT-PCR analysis of the expression of AK023391 in GC tissues and adjacent normal tissues. T: tumor tissue; N: normal tissue
