In this study, we first analyzed the expression levels of LINC00324 in human GC tissues by using raw microarray data downloaded from GEO (GSE53137)30, and found that LINC00324 expression levels were upregulated in GC tissues compared with the corresponding adjacent nontumorous tissues (Fig. 1a).Then, the expression levels of LINC00324 were investigated in 66 paired GC tissues and adjacent normal tissues by qRT-PCR and normalized to GAPDH. Here, GAPDH is linked to gastric cancer.
