Figure 1: The expression levels of HOTAIR were significantly upregulated in GC tissues and cells. (a) Difference between the expression levels of HOTAIR in 54 pairs of GC tissues and adjacent nontumor tissues. (b) The expression levels of HOTAIR in human GC cell lines AGS, MGC-803, SGC-7901, BGC-823, and a normal gastric epithelium cell line GES-1. The expression levels of HOTAIR were normalized to GAPDH. P<0.05.
